Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

Cloud Hosting Firm Loses All Customer Data After Ransomware Attack

CloudNordic, a Danish cloud hosting provider, has told customers to consider all of their data as having been lost following a ransomware infection that encrypted the large Danish cloud provider. The threat actors had destroyed the organisation’s backups, which prevented the firm from recovering effectively. The attack also impacted AzeroCloud, which is owned by the same company.

Worryingly, many organisations believe that having backups and using the cloud is enough for them to be able to recover from any cyber incident; unfortunately, as shown in the CloudNordic and AzeroCloud attacks, it is not enough. Organisations need to have a recovery plan in place which is tested and improved, to best strengthen themselves in the event of a cyber incident.

Would You Infect Others to Rid Yourself of Ransomware?

Hackers continually develop ransomware with new and creative attack methods that keep internet security professionals on their toes and pose challenges for people trying to detect threats. Victims of ransomware usually see messages asking them to pay for file access restoration; however, the Popcorn Time ransomware group takes a different approach to getting victims involved.

The Popcorn Time ransomware approach works via the referral method. The ransomware group is willing to give victims access to their files if they send the referral link to two other people, extending the attacker’s reach. Most people would hesitate to distribute a ransomware link through email, WhatsApp, or another method that is easy for victims to identify them as the perpetrators. Law enforcement bodies categorise ransomware attacks as crimes that come with hefty fines and prison time. Even those choosing to send the links to people they know face disastrous consequences beyond law enforcement, including the loss of jobs and relationships.

Artificial Intelligence and USBs Drive 8% Rise in Cyber Attacks

Checkpoint’s 2023 Mid-Year Security Report shows an 8% surge in global weekly cyber attacks during Q2, marking the most significant increase in two years. The report highlights the fusion of advanced artificial intelligence (AI) technology with traditional tools like USB devices used for disruptive cyber attacks.

Other significant findings include the evolution of ransomware tactics. The report found that ransomware groups are exploiting vulnerabilities in common corporate software and shifting focus from encrypting data to stealing it. USB devices have resurfaced as threats, employed by both state-affiliated groups and cyber-criminals to distribute malware globally. The misuse of AI has escalated, as attackers use generative AI tools for phishing emails, keystroke monitoring malware and basic ransomware code.

Ransomware Attacks Broke Records in July, Mainly Driven By One Group

A number of ransomware actors are utilising the threat of releasing sensitive data to get organisations to pay ransoms; in some cases this is combined with encryption to give the actor two avenues of payment. A report has found there were over 500 attacks last month, an increase of 153% compared to one year ago, and a 16% increase compared to June. Within Europe, there was a 59% increase in ransomware attacks from June to July.

Part of the significant rise is due to the ransomware group called Cl0p, whose attack on the MOVEit software has accounted for hundreds of victims this year. The Cl0p ransomware group has kept its promise to publish files on the clearweb of all its victims if contact was not made. The clearweb is simply what we know as the internet; anyone can access it. As such, there will be many organisations who are now having their sensitive data published and readily viewable for anyone who has access to the internet.

Cyber Risk in The Boardroom

The relationship between the CISO and the wider boardroom has become increasingly cooperative, with 77% of CEO’s seeing cyber as a strategic function and a potential source of competitive advantage. While it is ultimately up to the board to take steps to keep cybersecurity high on the agenda, the CISO also has a responsibility to press the message and bridge any gaps.

CISOs must deliver concerns, strategies and recommendations in a business-first manner, while avoiding jargon and overly technical language. Attracting and retaining good quality senior security professionals is very challenging in the current market and Black Arrow offer a fractional CISO service, giving access to a whole team of specialists with wider expertise, experience and backgrounds, for less than the cost of hiring one individual.

Malware-Infected Advertising Grows Ever More Sophisticated, And More Damaging

The malware exploits known as malware-infected ads, or malvertising, have been around for decades, but new reports point to a steady rise in efficacy. With malvertising, the infected ads are typically placed on legitimate ad networks, which makes them more difficult to spot and remove. The technique continues to use more and more sophisticated mechanisms for getting their infections spread throughout the web and keeping them running for a long time. The exploits can operate in one of several ways, including intercepting a user’s clickstream on random hyperlinks and substituting them with redirects to advertising websites.

Adblockers either on endpoints or at the network level can also help to prevent malvertising from causing harm.

Cyber Security is Everyone’s Responsibility

A recent survey found that 41% of respondents said that poor quality training, or a lack of training altogether, and insider threats were impacting their organisation’s security. Cyber security involves everyone as any employee can be an entry point for a cyber incident, but they also have the power to prevent one. It is important to make sure all employees are provided adequate training. Not every role requires the same training however, so it is important for organisations to identify and provide training that is appropriate to employees. Black Arrow provide live in person and online instructor lead cyber security training, both through Cyber Risk and Governance Workshops for Senior Leadership and Awareness, Behaviour and Culture Training for employees and contractors.

QR Code Hacks Are Another Thing to Worry About Now

One of the upcoming technologies thrust upon us is QR codes. At this point, you can find them at most restaurants and parking sites. You simply scan the code and you are taken to the relevant site, for example, the menu for the restaurant. Attackers have cottoned on to this and started to use QR codes in phishing attacks; the idea being that the victim will scan the code without scrutinising it and be taken to a malicious website instead.

Security Basics Aren’t So Basic Anymore

The basics of cyber security, it turns out, aren’t so basic anymore. What was considered basic has moved way beyond just having firewalls and antivirus, and the most basic controls nowadays include more advanced controls such as robust identity and access management, multi-factor authentication (MFA) and patching and vulnerability management. Many of these now basic controls are lacking or non-existent across the economy according to cyber security experts. A report found that only 28% of Microsoft users had MFA enabled as 2022 closed.

You can’t solve all the problems at once. However, progress on these fronts also relies heavily on the need for a cultural shift. Organisations need to get to the point where they view cyber security in the same light as locks on doors and seatbelts in cars.

Apple MacOS Security Myths

Apple has maintained a reputation as being more secure than other manufacturers, and whilst Apple has put many different security mechanisms into its operating system, no technology is bulletproof. Assuming an Apple device is invulnerable can lead users to believe that their Mac will not get viruses or be subject to a plethora of other cyber threats. As a result, this can lead to poor cyber hygiene from the individual, as they assume they are safe regardless of what they do. Apple users need to remain every bit as aware of risks, social engineering, keeping devices up to date, and having appropriate security controls.

Security Leaders Report Misalignment of Investments and Risk Reduction

The cyber risk landscape was analysed in a recent report that examined the amount of risk that organisations are willing to accept, their resource constraints and key priorities for approaching cyber risk in the future. The report found 66% of respondents indicating that they have limited visibility and insight into their cyber risk profiles, hindering their ability to prioritise investments and allocate resources effectively. 67% of organisations experienced a breach requiring attention within the last two years despite having traditional threat-based security measures in place. Further, 61% of security executives expressed concerns over the current misalignment between cyber security investments and their organisation's risk reduction priorities.

Many CISOs Tout SaaS (Cloud) Cyber Security Confidence, but 79% Admit to Incidents

Cyber security, IT, and business leaders alike recognise SaaS (cloud) cyber security as an increasingly important part of the cyber threat landscape. And at first glance, respondents appear generally optimistic about their SaaS cyber security as 85% answered that they are confident or very confident in their company's or customer's data security in sanctioned SaaS apps.

Despite the confidence, 79% of respondents confirmed that their organisation had identified SaaS cyber security incidents over the past 12 months. Many of those incidents occurred in environments with cyber security policies in place and enforced, as 66% of respondents claimed in their responses.

If You Ever Used Duolingo, Watch Out for Phishing Email

Users of Duolingo, past and present, should be wary of phishing emails as data on about 2.6 million accounts were scraped through an exposed application programming interface (API), and then offered on a hacking forum back in January. Login and real names, email addresses, phone numbers, and courses studied were part of the collection, which went for $1,500. Now that data has resurfaced on a different forum, and at a substantially lower cost of just a few dollars, users of the service can expect this data to be used in fresh phishing campaigns.

91% of Security and IT Professionals: Criminals are Already Using AI in Email Attacks

Recent research found that 91% of security and IT professionals are noticing cyber criminals already using AI as part of email attack campaigns, with 74% indicating they have experienced an increase in the use of AI by cyber criminals in the past six months. This is worrying as 52% reported that email security is among one of their top three concerns.

Organisations need to make sure that their technologies, procedures and policies are updated to factor in AI-enabled email attacks to help reduce the risk they pose to the organisation. Such improvements should also include employees.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

  • 50% of UK CEOs see Cyber as a Bigger Business Risk than the Economy

Half of UK CEOs consider cyber security as a bigger risk to their organisation than economic uncertainty, a new study by Palo Alto Networks has found. The findings came from a survey of 2500 CEOs from the UK, Germany, France, Brazil and the UAE at large organisations (500+ employees).

Despite the recognition of the business threats posed by cyber attacks, UK CEOs have a lower level of understanding of cyber security risks than their international counterparts, with just 16% saying they have a complete understanding. This compares to 21% in Brazil, 21% in the UAE, 22% in France and 39% in Germany. Additionally, many UK CEOs feel detached from responsibility for cyber security at their organisations, instead leaving it to the responsibility of IT, although IT is only part of the solution.

  • Report Finds 78% of Organisations Felt Prepared for Ransomware Attacks, Yet Half Still Fell Victim

Fortinet has unveiled its 2023 Global Ransomware Report based on a recent global survey and explores cyber security leaders’ perspectives on ransomware, particularly how it impacted their organisations in the last year and their strategies to mitigate an attack. The report found that the global threat of ransomware remains at peak levels, with half of organisations across all sizes, regions and industries falling victim in the last year.

The top challenges to stopping a ransomware attack were people and process related, with many organisations lacking clarity on how to secure against the threat. Specifically, four out of the five top challenges to stopping ransomware were people or process related. The second largest challenge was a lack of clarity on how to secure against the threat as a result of a lack of user awareness and training and no clear chain-of-command strategy to deal with attacks.

Despite the global macroeconomic environment, security budgets will have to increase in the next year with a focus on AI/ML technologies to speed detection, centralised monitoring tools to speed response and better preparation of people and processes.

  • SMBs and Regional MSPs are Increasingly Targeted by State-Sponsored APT Groups

Advanced persistent threat (APT) attacks were once mainly a concern for large corporations in industries that presented cyber espionage interest. That's no longer the case and over the past year in particular, the number of such state-sponsored attacks against small- and medium-sized businesses (SMBs) has increased significantly.

Cyber security firm Proofpoint analysed its telemetry data more than 200,000 SMB customers over the past year and saw a rise in phishing campaigns originating from APT groups, particularly those serving Russian, Iranian, and North Korean interests.

SMBs are also targeted by APT groups indirectly, through the managed services providers (MSPs) that maintain their infrastructure. Proofpoint has seen an increase in attacks against regional MSPs because their cyber security defences could be weaker than larger MSPs yet they still serve hundreds of SMBs in local geographies.

https://www.csoonline.com/article/3697648/smbs-and-regional-msps-are-increasingly-targeted-by-state-sponsored-apt-groups.html#tk.rss_news

  • IT Employee Piggybacked on Cyber Attack for Personal Gain

A 28-year-old former IT employee of an Oxford-based company has been convicted of blackmailing his employer and unauthorised access to a computer with intent to commit other offences.

The convicted employee was the one who began to investigate the incident and, along with colleagues and the police, tried to mitigate it and its fallout. But he also realized that he could take advantage of the breach to line his own pockets.

“He accessed a board member’s private emails over 300 times as well as altering the original blackmail email and changing the payment address provided by the original attacker. This was in the hope that if payment was made, it would be made to him rather than the original attacker,” the South East Regional Organised Crime Unit (SEROCU) revealed. He went as far as creating an almost identical email address to that of the original attacker, using it to pressure his employer into making the payment.

While some insider threats may stem from negligence or ignorance, this case highlights a more sinister scenario involving a malicious, opportunistic individual. Malicious insiders exploit their authorized access and privileges to engage in harmful, unethical, or illegal activities.

  • Ransomware Threats Are Growing, and Targeting Microsoft Devices More and More

Ransomware attacks have never been this popular, a new report from cyber security researchers Securin, Ivanti, and Cyware has stated. New ransomware groups are emerging constantly, and new vulnerabilities being exploited are being discovered almost daily, but out of all the different hardware and software, Microsoft’s products are being targeted the most.

Attackers are now targeting more than 7,000 products built by 121 vendors, all used by businesses in their day-to-day operations. Most products belong to Microsoft, which has 135 vulnerabilities associated with ransomware. In just March 2023, there had been more breaches reported, than in all three previous years combined. Even though most cyber security incidents never get reported, too. In the first quarter of the year, the researchers discovered 12 new vulnerabilities used in ransomware attacks, three-quarters of which (73%) were trending in the dark web.

  • Microsoft Reports Jump in Business Email Compromise (BEC) Activity

Thirty-five million business email compromise (BEC) attempts were detected in the last year, according to the latest Microsoft Cyber Signals report. Activity around BEC spiked between April 2022 and April 2023, with over 150,000 daily attempts, on average, detected by Microsoft’s Digital Crimes Unit.

Rather than targeting unpatched devices for vulnerabilities, BEC operators focus on leveraging the vast volume of daily email and other message traffic to trick victims into sharing financial information or unknowingly transferring funds to money mule accounts. Their goal is to exploit the constant flow of communication to carry out fraudulent money transfers.

Using secure email applications, securing identities to block lateral movement, adopting a secure payment platform and training employees are a few effective methods, according to the report.

  • Forrester Predicts 2023’s Top Cyber security Threats: From Generative AI to Geopolitical Tensions

The nature of cyber attacks is changing fast. Generative AI, cloud complexity and geopolitical tensions are among the latest weapons and facilitators in attackers’ arsenals. Three-quarters (74%) of security decision-makers say their organisations’ sensitive data was “potentially compromised or breached in the past 12 months” alone. Forrester’s Top Cyber security Threats in 2023 report provides a stark warning about the top cyber security threats this year, along with prescriptive advice to CISOs and their teams on countering them. By weaponising generative AI and using ChatGPT, attackers are fine-tuning their ransomware and social engineering techniques.

Perimeter-based legacy systems not designed with an AI-based upgrade path are the most vulnerable. With a new wave of cyber attacks coming that seek to capitalise on any given business’ weakest links, including complex cloud configurations, the gap between reported and actual breaches will grow.

Forrester cites Russia’s invasion of Ukraine and its relentless cyber attacks on Ukrainian infrastructure as examples of geopolitical cyber attacks with immediate global implications. Forrester advises that nation-state actors continue to use cyber attacks on private companies for geopolitical purposes like espionage, negotiation leverage, resource control and intellectual property theft to gain technological superiority.

  • Advanced Phishing Attacks Surge 356% in 2022

A new report published this week observed a 356% growth in the number of advanced phishing attacks attempted by threat actors in 2022, with the total number of attacks having increased by 87%. Among the reasons behind this growth is the fact that malicious actors continue to gain widespread access to new tools, including artificial intelligence (AI) and machine learning (ML)-powered tools. These have automated the process of generating sophisticated attacks, including those characterized by social engineering as well as evasion techniques.

The global threat landscape continues to evolve with a meteoric rise in the number of attacks, combined with increasingly sophisticated attack techniques designed to breach and damage organisations.

Additionally, the report highlighted that the changing threat landscape has resulted from the swift adoption of new cloud collaboration apps, cloud storage and productivity services for external collaboration.

https://www.infosecurity-magazine.com/news/advanced-phishing-attacks-surge/

  • Today’s Cyber Defence Challenges: Complexity and a False Sense of Security

Organisations can mistakenly believe that deploying more security solutions will result in greater protection against threats. However, the truth of the matter can be very different. Gartner estimates that global spending on IT security and risk management solutions will exceed $189.7 billion annually in 2023, yet the breaches keep on coming. Blindly purchasing more security tools can add to complexity in enterprise environments and creates a false sense of security that contributes to today’s cyber security challenges.

To add to the dilemma, the new work-from-anywhere model is putting a strain on IT and security teams. Employees shifting between corporate and off-corporate networks are creating visibility and control challenges, which are impacting those teams’ ability to diagnose and remediate end user issues and minimize cyber security risks. In addition, they have to deal with a broad mix of networks, hardware, business and security applications, operating system (OS) versions, and patches.

https://www.securityweek.com/todays-cyber-defense-challenges-complexity-and-a-false-sense-of-security/

  • Almost All Ransomware Attacks Target Backups

Data stored in backups is the most common target for ransomware attackers. Almost all intrusions (93%) target backups and in 75% of cases succeed in taking out victims’ ability to recover. In addition, 85% of global organisations suffered at least one cyber attack in the past year according to the Veeam 2023 Ransomware trends report. Only 16% of organisations avoided paying ransom because they were able to recover from backups, down from 19% in last year’s survey.

According to the survey, criminals attempt to attack backup repositories in almost all (93%) cyber events in EMEA, with 75% losing at least some of their backups and more than one-third (39%) of backup repositories being completely lost.

Other key findings included that 21% said ransomware is now specifically excluded from insurance policies; and of those with cyber insurance, 74% saw increased premiums since their last policy renewal.

With most ransomware actors moving to double and triple extortion the days of a backup being all you need to keep you safe are far behind and firms should do more to prevent being the victim of ransomware in the first place.

https://www.computerweekly.com/news/366538492/Almost-all-ransomware-attacks-target-backups-says-Veeam

  • NCSC Warns Against Chinese Cyber Attacks on Critical Infrastructure

The UK National Cyber Security Centre (NCSC) and several other international security agencies have issued a new advisory warning the public against Chinese cyber activity targeting critical national infrastructure networks. According to the document, the People’s Republic of China (PRC)’s associated threat actors employed sophisticated tactics to evade detection while conducting malicious activities against targets in the US and Guam. These tactics are expected to be used on critical infrastructure targets outside the US, including the UK.

The document further added that the threat actors mainly focused on credential access theft via brute force and password spraying techniques. The NCSC advisory provides network defenders with technical indicators and examples of techniques used by the attacker to help identify any malicious activity.

https://www.infosecurity-magazine.com/news/ncsc-warns-chinese-cyber-attacks/

  • Half of All Companies were Impacted by Spearphishing in 2022

Spearphishing is a sliver of all email exploits but the extent to which it succeeds is revealed in a new study from cyber security firm Barracuda Networks, which analysed 50 billion emails across 3.5 million mailboxes in 2022, unearthing around 30 million spearphishing emails and affecting 50% of all companies.

The report identified the top prevalent spearphishing emails were Scamming (47%) used to trick victims into disclosing sensitive information and the other being brand impersonation (42%) attacks mimicking a brand familiar with the victim to harvest credentials.

The report found that remote work is increasing risks. Users at companies with more than a 50% remote workforce report higher levels of suspicious emails — 12 per day on average, compared to 9 per day for those with less than a 50% remote workforce.

https://www.techrepublic.com/article/barracuda-networks-spearphishing-study/

  • Google's .zip, .mov Domains Give Social Engineers a Shiny New Tool

Two new top-level domain names (.zip and .mov) have caused concern among security researchers, who say they allow for the construction of malicious URLs that even tech-savvy users are likely to miss. While a top-level domain (TLD) that mimics a file extension is only one component in the lookalike attack, the overall combination is much more effective with the .zip or .mov extension.

There's no question that phishing links that involve these TLDs can be used to lure unsuspecting users into accidentally downloading malware. Unlike other kinds of phishing URLs that are intended to lure the user to enter credentials into a phony login page, the lures with the .zip or .mov domains are more suited to drive-by download types of attacks.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

  • Three Ransomware Gangs Consecutively Attacked the Same Network

Hive, LockBit and BlackCat, three prominent ransomware gangs, consecutively attacked the same network, according to Sophos. The first two attacks took place within two hours, and the third attack took place two weeks later. Each ransomware gang left its own ransom demand, and some of the files were triple encrypted.

It’s bad enough to get one ransomware note, let alone three. Multiple attackers create a whole new level of complexity for recovery, particularly when network files are triple encrypted. Cyber security that includes prevention, detection and response is critical for organisations of any size and type—no business is immune.

The “Multiple Attackers: A Clear and Present Danger” whitepaper further outlines additional cases of overlapping cyber attacks, including cryptominers, remote access trojans (RATs) and bots. In the past, when multiple attackers have targeted the same system, the attacks usually occurred across many months or multiple years. The attacks described in Sophos’ whitepaper took place within days or weeks of each other—and, in one case, simultaneously—often with the different attackers accessing a target’s network through the same vulnerable entry point.

Typically, criminal groups compete for resources, making it more difficult for multiple attackers to operate simultaneously. Cryptominers normally kill their competitors on the same system, and today’s RATs often highlight bot killing as a feature on criminal forums. However, in the attack involving the three ransomware groups, for example, BlackCat—the last ransomware group on the system—not only deleted traces of its own activity, but also deleted the activity of LockBit and Hive.

In another case, a system was infected by LockBit ransomware. Then, about three months later, members of Karakurt Team, a group with reported ties to Conti, was able to leverage the backdoor LockBit created to steal data and hold it for ransom.

  • As The Cost of Cyber Insurance Rises, The Number of Organisations Who Can’t Afford It Is Set to Double

The number of organisations that will be either unable to afford cyber insurance, be declined cover, or experience significant coverage limitations is set to double in 2023, according to Huntsman Security.

Even for those insured, the perfect storm of ongoing attacks, tightening regulations and growing financial pressures is making it more likely that any attack on an organisation will leave it exposed.

Factors like the supply chain crisis, inflation and skill shortages are all adding to the difficulty for organisations trying to execute on their cyber security strategy. At the same time, increases in insurance premiums, limits on coverage, increasing underwriting rigour, and capacity constraints are all limiting the accessibility of cyber insurance, for many.

Loss ratios will not improve until premium incomes better match the current level of pay-outs. With this reduced insurance access alongside increasing cyber threats and tightening regulations, many organisations are losing cyber insurance as an important risk management tool. Even those who can still get insurance are paying a prohibitively high cost.

With a third of UK firms subject to cyber attacks at least once a week, cyber insurance as part of overall risk management is crucial. To bridge this accessibility gap insurers are seeking to improve the quality of risk information, so premiums better reflect the true cost of that risk. Unless organisations can demonstrate they have insurers’ specified controls in place to manage their security risks, insurers will continue to have difficulty quantifying that risk. It’s for these reasons that insurers have changed the basis upon which their products are offered to reflect the risk being underwritten more accurately.

In this environment, improving and demonstrating the effectiveness of security controls will now be essential: both for organisations looking to improve their cyber resilience and oversight while enhancing their eligibility for insurers, and for insurers who need to minimise their own exposure by ensuring the accuracy of their risk pricing process.

  • Identity Cyber Attacks, Microsoft 365 Dominate Cyber Security Incidents, Expel Research Finds

Identity-based cyber attacks (including credential theft, credential abuse and long-term access key theft) accounted for 56% of all incidents in Q2 of 2022, and Microsoft 365 remained the prime target for SaaS attacks, according to Expel’s Quarterly Threat Report.

Among the key findings:

  • Business email compromise (BEC) and business application compromise (BAC) access to application data represented 51% of all incidents.

  • Identity-based attacks in popular cloud environments like Amazon Web Services (AWS) accounted for 5%.

  • Ransomware groups change tactics, with threat groups and their affiliates all but abandoning the use of Visual Basic for Application (VBA) macros and Excel 4.0 macros to gain initial entry to Windows-based environments. In Q1, a macro-enabled Microsoft Word document (VBA macro) or Excel 4.0 macro was the initial attack vector in 55% of all pre-ransomware incidents. In Q2, that figure fell sharply to 9%. Instead, ransomware operators opted to use disk image (ISO), short-cut (LNK) and HTML application (HTA) files to gain initial entry.

  • Cloud attacks are becoming more sophisticated, with 14% of identity attacks against cloud identity providers tackling the multi-factor authentication (MFA) requirement by continuously sending push notifications.

  • Microsoft 365 is a common threat target, with BEC in Microsoft Office 365 (O365) remaining the top threat to organisations in Q2. 45% of all Q2 incidents were BEC attempts in O365. No BEC attempts were identified in Google Workspaces. 19% of BEC attempts bypassed MFA in O365 using legacy protocols, a 16% increase of compared to Q1.

  • Exploit Activity Surges 150% in Q2 Thanks to Log4Shell

Detections of malware events, botnet activity and exploits all increased significantly in the second quarter of 2022, according to new data from Nuspire.

The managed security services provider (MSSP) gathered the data from its endpoint detection and response (EDR) and managed detection and response (MDR) tools to produce its Q2 2022 Quarterly Threat Report.

The company recorded an increase in malware events of over 25%, a doubling of botnet detections and a rise in exploit activity of 150% versus the first quarter.

Botnet activity in particular surged towards the end of Q2, thanks to the Torpig Mebroot botnet – a banking trojan designed to scrape credit card and payment information from infected devices, the report revealed. Nuspire claimed it is particularly difficult to detect and remove, because it targets a machine’s master boot record.

It attributed much of the surge in exploit activity to the persistent threat posed by the Log4j bugs discovered at the end of December 2021. At the time, experts warned that the ubiquity of the utility, and the difficulty many organisations have in finding all instances of the CVE due to complex Java dependencies, means it may be exploited for years.

  • Ransomware Is Not Going Anywhere: Attacks Are Up 24%

Avast released a report revealing a significant increase in global ransomware attacks, up 24% from Q1/2022. Researchers also uncovered a new zero-day exploit in Chrome, as well as signals of how cyber criminals are preparing to move away from macros as an infection vector.

After months of decline, global ransomware attacks increased significantly in Q2/2022, up 24% from the previous quarter. The highest quarter-on-quarter increases in ransomware risk ratio occurred in Argentina (+56%), UK (+55%), Brazil (+50%), France (+42%), and India (+37%).

Businesses and consumers should be on guard and prepared for encounters with ransomware, as the threat is not going anywhere anytime soon.

The decline in ransomware attacks observed in Q4/2021 and Q1/2022 were thanks to law enforcement agencies busting ransomware group members, and caused by the war in Ukraine, which also led to disagreements within the Conti ransomware group, halting their operations. Things dramatically changed in Q2/2022. Conti members have now branched off to create new ransomware groups, like Black Basta and Karakurt, or may join other existing groups, like Hive, BlackCat, or Quantum, causing an uptick in activity.

  • Email Is the Single Biggest Threat to Businesses, And Here’s What You Can Do About It

Email remains one of the most popular methods of communication, particularly for business communications. There were 316.9 billion emails sent and received every day in 2021, and this is set to increase to 376.4 billion by 2025. But despite the scale of its use and how much people exchange confidential information over email, it is not a secure system by design.

Consequently, email is a major attack vector for organisations of all sizes. Deloitte found that 91% of all cyber attacks originate from a phishing email (an email that attempts to steal money, identity or personal information through a spoof website link that looks legitimate). The cost to organisations can be catastrophic with the National Cyber Security Centre (NCSC) reporting in August 2021 that phishing email attacks had cost UK organisations more than £5 million in the past 13 months.

It’s not enough for individuals to create complex passwords or rely on the security services of their email provider. Spam filters are not enough to stop malicious emails creeping into inboxes. Fortunately, safeguarding your emails with enterprise-grade email security doesn’t have to cost the earth or be hard to integrate so businesses of any size can protect themselves.

  • Realtek SDK Vulnerability Exposes Routers from Many Vendors to Remote Attacks

A serious vulnerability affecting the embedded Configurable Operating System (eCos) software development kit (SDK) made by Taiwanese semiconductor company Realtek could expose the networking devices of many vendors to remote attacks.

The security hole, tracked as CVE-2022-27255 and rated ‘high severity’, has been described as a stack-based buffer overflow that can allow a remote attacker to cause a crash or achieve arbitrary code execution on devices that use the SDK. An attack can be carried out through the wide area network (WAN) interface using specially crafted session initiation protocol (SIP) packets.

The Realtek eCos SDK is provided to companies that manufacture routers, access points and repeaters powered by RTL819x family SoCs. The SDK implements the base functionalities of the router, including the web administration interface and the networking stack. Vendors can build on top of this SDK to add custom functionality and their branding to the device.

Realtek informed customers about the eCos SDK vulnerability in March, when it announced the availability of a patch. However, it’s up to the original equipment manufacturer (OEM) using the SDK to ensure that the patch is distributed to end-user devices.

The vulnerability can be exploited remotely — directly from the internet — to hack affected routers running with default settings. No user interaction is required for successful exploitation.

  • Most Companies Are at An Entry-Level When It Comes to Cloud Security

Ermetic released a study by Osterman Research that found 84% of respondents were at an entry-level (one or two rating, with four being the highest) in terms of their cloud security capabilities.

The study found that only 16% ranked on the Ermetic Cloud Security Model at the top two levels, and 80% of companies said they lack a dedicated security team responsible for protecting cloud resources from threats.

“One of the most unexpected findings that emerged from this study was the lack of cloud security maturity among the largest enterprises surveyed,” said the author of the report. “Less than 10% of companies with more than 10,000 employees reported being at the top two maturity levels, while nearly 20% of smaller enterprises have achieved repeatable or automated & integrated cloud security capabilities.”

The report shows why new cloud data breaches are being reported all the time. Multi-cloud deployments, plus low investment in security, does not make for a good combination.

The new frontiers of cyber security, such as cloud security or internet of things (IoT) security are often at early stages of maturity. Organisations that are mature in their IT and data centre security are already overwhelmed and stretched thin and that’s why automation and simplification will help organisations accelerate their maturity in areas like cloud security.

There’s a mistaken belief that cloud computing environments inherently have security built-in — they don’t.

  • The Impact of Exploitable Misconfigurations on Network Security

Network professionals feel confident with their security and compliance practices but data suggests that they also leave their organisations open to risk, which is costing a significant amount of revenue, according to Titania.

In addition, some businesses are not minimising their attack surface effectively. Companies are prioritising firewall security and chronicle a fast time to respond to misconfigurations when detected in annual audits. However, switches and routers are only included in 4% of audits and these devices play a vital role in reducing an organisation’s attack surface and preventing lateral movement across the network.

Respondents also indicated that financial resources allocated to mitigating network configuration, which currently stands around 3.4% of the total IT budget, and a lack of accurate automation are limiting factors in misconfiguration risk management.

The study, which surveyed 160 senior cyber security decision-makers revealed:

  • Misconfigurations cost organisations millions, up to 9% of their annual revenue but the true cost is likely to be higher.

  • Compliance is a top priority, with 75% of organisations across all sectors saying their business relies on compliance to deliver security. Whilst almost every organisation reported that it is meeting its security and compliance requirements, this is at odds with a number of the other findings from the survey and other reports that show a decline in organisations maintaining full compliance with regulated data security standards.

  • Remediation prioritisation is a challenge. 75% said their network security tools meant they could categorise and prioritise compliance risks ‘very effectively’. However, 70% report difficulties prioritising remediation based on risk and also claim inaccurate automation as the top challenges when meeting security and compliance requirements.

  • Routers and switches are mostly overlooked. 96% of organisations prioritise the configuration and auditing of firewalls, but not routers or switches. This leaves these devices exposed to potentially significant and unidentified risks.

  • Industrial Spy Ransomware: New Threat Group Emerges to Exfiltrate Data, Extort Victims

A new ransomware group dubbed Industrial Spy that first emerged in April 2022 is specialising in exfiltration and double extortion tactics and has the potential to do significant damage, Zscaler’s threat tracking team said.

The threat crew has shown that it possesses the capability to breach organisations and have been “actively adding unencrypted data from two or three victims every month,” Zscaler said. In some instances, the threat group appears to only exfiltrate and ransom data. In other cases, they encrypt, exfiltrate and ransom the data, the cloud security provider said.

At this point, it’s not clear who’s behind the threat entry or if it’s nation-state affiliated. The group started as a data extortion marketplace where criminals could buy large companies’ internal data, promoting the marketplace through Readme.txt files downloaded using malware downloaders.

In May, 2022, the threat group introduced their own ransomware to create double extortion attacks that combine data theft with file encryption.

What you need to know:

  • Industrial Spy started by ransoming stolen data and more recently has combined these attacks with ransomware.

  • The threat group exfiltrates and sells data on their dark web marketplace, but does not always encrypt a victim’s files.

  • The ransomware utilises a combination of RSA and 3DES to encrypt files.

  • Industrial Spy lacks many common features present in modern ransomware families.

  • The Industrial Spy ransomware family is relatively basic, and parts of the code appear to be in development.

  • UK NHS Service Recovery May Take a Month After MSP Ransomware Attack

Managed service provider (MSP) Advanced confirmed that a ransomware attack on its systems disrupted emergency services (111) from the United Kingdom's National Health Service (NHS). Customers of seven solutions from the British MSP have been impacted either directly or indirectly, the company said. The first has stated it could take a month to recover systems to full service.

The ransomware attack started to disrupt Advanced systems on Thursday, August 4 and was identified around 7 AM. It caused a major outage to NHS emergency services across the UK.

Advanced did not disclose the ransomware group behind the attack but said that it took immediate action to mitigate the risk and isolated Health and Care environments where the incident was detected. The company is working with forensic experts from Microsoft (DART) and Mandiant, who are also helping bring the affected systems back online securely and with added defences:

  • Implementing additional blocking rules and further restricting privileged accounts for Advanced staff

  • Scanning all impacted systems and ensuring they are fully patched

  • Resetting credentials

  • Deploying additional endpoint detection and response agents

  • Conducting 24/7 monitoring

After implementing the security measures above, Advanced said it would restore connectivity to its environments and assist customers to gradually reconnect safely and securely.

  • A Single Flaw Broke Every Layer of Security in MacOS

Every time you shut down your Mac, a pop-up appears: “Are you sure you want to shut down your computer now?” Nestled under the prompt is another option most of us likely overlook: the choice to reopen the apps and windows you have open now when your machine is turned back on. Researchers have now found a way to exploit a vulnerability in this “saved state” feature—and it can be used to break the key layers of Apple’s security protections.

The vulnerability, which is susceptible to a process injection attack to break macOS security, could allow an attacker to read every file on a Mac or take control of the webcam. It's basically one vulnerability that could be applied to three different locations.

Top Cyber Stories of the Last Week

  • Business Email Compromise (BEC) Attacks Have Risen 53% Year-Over-Year

Armorblox released a report which highlights the use of language-based attacks that bypass existing email security controls. The report uncovers how the continued increase in remote working has made critical business workflows even more vulnerable to new forms of email-based attacks, often resulting in financial fraud or credential theft.

Language-based attacks have become the new normal for business email compromise (BEC) with 74% of these attacks using language as the main attack vector.

Security teams spend a massive amount of time configuring rules and exceptions in their email security solutions to block impersonation emails – both for executives and other employees. Despite all of that manual work and rule writing, 70% of impersonation emails evaded email security controls.

  • Ransomware Attacks Setting New Records

Zscaler released the findings of its annual ThreatLabz Ransomware Report, which revealed an 80 percent increase in ransomware attacks year-over-year.

In 2022, the most prevalent ransomware trends include double-extortion, supply chain attacks, ransomware-as-a-service, ransomware rebranding, and geo-political incited ransomware attacks. The report details which industries are being targeted the most by cyber criminals, explains the damage caused by double-extortion and supply chain attacks, and catalogues the most active ransomware groups operating today.

Modern ransomware attacks require a single successful asset compromise to gain initial entry, move laterally, and breach the entire environment, making legacy VPN and flat networks extremely vulnerable. Attackers are finding success exploiting weaknesses across businesses’ supply chains as well as critical vulnerabilities like Log4Shell, PrintNightmare, and others. And with ransomware-as-a-service available on the darkweb, more and more criminals are turning to ransomware, realising that the odds of receiving a big payday are high.

The tactics and scope of ransomware attacks have been steadily evolving, but the end goal continues to be a disruption of the target organisation and theft of sensitive information for the purposes of ransom. The size of the ransom often depends on the number of systems infected and the value of the data stolen: the higher the stakes, the higher the payment. In 2019, many ransomware groups updated their tactics to include data exfiltration, commonly referred to as a ‘double extortion’ ransomware.

  • Hackers Are Now Hiding Inside Networks for Longer. That's Not a Good Sign

Cyber criminals are spending more time inside networks before they're discovered, and that's allowing them to do more damage.

The amount of time cyber criminal intruders are spending inside victims' networks is increasing, providing them with the ability to carry out higher complexity campaigns and more damaging cyber attacks.

According to analysis by cyber security researchers at Sophos, who examined incidents targeting organisations around the world and across a wide range of industry sectors, the median dwell time that cyber criminals spend inside compromised networks is now 15 days, up from 11 days the previous year.

Dwell time is the amount of time hackers are inside the network before they're discovered or before they leave – and being able to spend an increased amount of time inside a compromised network undetected means they're able to more carefully conduct malicious activity, such as monitoring users, stealing data or laying the foundations for a malware or ransomware attack.

  • Paying Ransomware Paints Bigger Bullseye on Target’s Back

Ransomware attackers often strike targets twice, regardless of whether the ransom was paid.

Paying ransomware attackers doesn’t pay off and often paints a bigger target on a victim’s back. Eighty percent of ransomware victims that paid their attackers were hit a second time by the malware scourge.

New ransomware numbers come from a Cybereason’s April ransomware survey of 1,456 cyber security professionals. According to the gated report (registration required), victims that were successfully extorted were not only targeted a second time, but frequently data encrypted by criminals later became unusable during the decryption process because of corruption issues.

The fact that ransomware gangs strike so quickly a second and third time isn’t surprising, because they will try to profit in any possible way so why not hit the same company, demand a higher ransom, and get paid again?

  • Organisations Fix Only 1 in 10 Vulnerabilities Monthly

New research from SecurityScorecard features a couple of eye-popping “only” findings: Only 10 percent of vulnerabilities are remediated each month, and only 60 percent of companies have improved their security profile despite a 15-fold increase in the number of cyber incidents in the last three years.

That’s not good. The research, which sought to measure how long it took the 1.6 million organisations assessed to remediate vulnerabilities in the three-year period from 2019 to 2022, also found the following:

·       53% had at least one exposed vulnerability to the internet, while 22% of organisations amassed more than 1,000 vulnerabilities each, confirming more progress is required to protect organisations’ critical assets.

·       The financial sector is among the slowest remediation rates (median to fix 50% = 426 days), while utilities ranked among the fastest (median = 270 days).

·       Despite a 15-fold increase in exploitation activity for vulnerabilities with published exploit code, there was little evidence that organisations in the financial sector fixed exploited flaws faster.

·       The IT sector (62.6%) and public sector (61.6%) had the highest prevalence of open vulnerabilities.

·       The financial sector (48.6%) exhibited the lowest proportion of open vulnerabilities; however, there is less than a 10% difference between this and other sectors in terms of industries with the most open vulnerabilities.

·       It typically takes organisations 12 months to remediate half of the vulnerabilities in their internet-facing infrastructure.

·       When firms have fewer than 10 open vulnerabilities, it can take about a month to close just half of them, but when the list grows into the hundreds, it takes up to a year to reach the halfway point.

  • Cyber Attack Surface "Spiralling Out of Control"

Global organisations are still beset with cyber visibility and control challenges, with two-fifths (43%) admitting their digital attack surface is out of control as a result, according to new Trend Micro research.

The security vendor polled over 6200 IT and business decision-makers to compile its new study, ‘Mapping the digital attack surface: Why global organisations are struggling to manage cyber risk’.

It revealed that nearly three-quarters (73%) are concerned about the increasing size of their attack surface. Over a third (37%) said it is “constantly evolving and messy,” and just half (51%) thought they were able to fully define its extent.

These visibility challenges are greatest in cloud environments, although problems persist across the board. The report highlights complex supply chains, tool bloat and home working-driven shadow IT as additional contributory factors.

On average, respondents estimated having just 62% visibility of their attack surface.

https://www.infosecurity-magazine.com/news/cyberattack-surface-out-of-control/

  • Phishing Hits All-Time High in Q1 2022

The first quarter of 2022 saw phishing attacks hit a record high, topping one million for the first time, according to data from the Anti Phishing Working Group (APWG).

The industry, law enforcement and government coalition’s new Phishing Activity Trends Report also revealed that March was the worst month on record for phishing, with 384,291 attacks detected.

The financial sector was the worst hit, accounting for 24% of all detected attacks, although webmail and SaaS providers were also popular targets.

Attacks spoofing retailers dropped 17% from the previous quarter to 15% following the busy holiday shopping season, while those against social media services rose significantly, from nearly 9% percent of all attacks to 13% over the same period.

  • Ransomware's ROI Retreat Will Drive More BEC Attacks

Law enforcement crackdowns, tighter cryptocurrency regulations, and ransomware-as-a-service (RaaS) operator shutdowns are driving down the return on investment for ransomware operations across the globe.

A presentation at the RSA Conference last week laid out analysis of the ransomware threat landscape, predicting that there will be a pivot from ransomware toward renewed interest in basic business email compromise (BEC) attacks in the next 6 to 12 months.

Ransomware attacks grab headlines and have been supercharged by a few prolific RaaS operators, but crackdowns on just one group can make an enormous dent.

Ransomware is a centralised ecosystem with small numbers of operators responsible for the majority of attacks.

The recent disappearance of Pysa, left just two groups, Conti and Lockbit, with more than 50% of the share of the total ransomware attacks in the first half of 2022. BEC groups, on the other hand, are diffuse and scattered, making them much harder to eradicate.

Although they're not as quick to make the headlines, BEC attacks have cost business more than $43 billion since 2016, according to the FBI, and make up $1 out of every $3 lost to cyber attacks, far outpacing ransomware losses.

Ransomware has had a moment over the past couple of years, in part because once threat actors were able to abandon arcane wire transfers to collect ransoms and rely on cryptocurrency, caps on transactions were lifted and it became simple to collect much larger amounts. But new crypto regulations are chilling the ability of these cyber criminals to rely on its infrastructure to do business, adding "friction" to the transactions.

BEC attacks, by comparison, rely on social engineering to corrupt a business's financial supply chain to get employees to willingly part with the cash, making them exponentially harder to track and stop.

  • The Real Cost of Cyber Attacks: What Organisations Should Be Prepared For

With each passing year, hackers and cyber criminals of all kinds are becoming more sophisticated, malicious, and greedy conducting brazen and often destructive cyber-attacks that can severely disrupt a company’s business operations. And this is a big problem, because, first and foremost, customers rely on a company’s ability to deliver services or products in a timely manner. Cyber attacks not only can affect customers’ data, but they can impact service delivery.

Data breaches and costs associated with them have been on the rise for the past few years, but, according to a 2021 report, the average cost per breach increased from $3.86 million in 2020 to $4.24 million in 2021. The report also identified four categories contributing most global data breach costs – Lost business cost (38%), Detection and escalation (29%), Post breach response (27%), and Notification (6%).

Ransomware attacks cost an average of $4.62 million (the cost of a ransom is not included), and destructive wiper-style attacks cost an average of $4.69 million, the report said.

For a business, a data breach is not just a loss of data, it can also have a long-lasting impact on operations and undermine customers’ trust in the company. In fact, a survey revealed that 87% of consumers are willing to take their business elsewhere if they don’t trust a company is handling their data responsibly. Therefore, the reputational damage might be detrimental to a business’ ability to attract new customers.

  • Why Smishing and Vishing Attempts Surged In 2021

In The Human Factor Report 2022, security vendor Proofpoint found that SMS phishing (smishing) attacks more than doubled year-on-year in 2021. The report is based on their analysis of over 2.6 billion email messages, 49 billion URLs, 1.9 billion attachments, 28 million cloud accounts and 1.7 billion mobile messages.

The study details the most common attack surfaces and methods including categories of risk, vulnerabilities, attacks, Russian Aligned APT’s, and Privilege as a vector.

Key Findings:

  • Managers and executives make up only 10% of users, but almost 50% of the most severe attack risk

  • Attackers attempt to initiate more than 100,000 telephone-oriented attacks every day.

  • Malicious URLS are 3-4x more common than malicious attachments.

  • Smishing attempts more than doubled in the US over the year, while in the UK over 50% of lures are themed around delivery notification.

  • More than 20 million messages attempted to deliver malware linked to eventual ransomware attack

  • Data loss prevention alerts have stabilised as businesses adopt permanent hybrid work models.

  • 80% of businesses are attacked by a compromised supplier account in any given month.

  • 35% of cloud tenants that received a suspicious login also saw suspicious post-access activity.

  • Know Your Enemy! Learn How Cyber Crime Adversaries Get In…

Cyber security vendor Sophos dug into the incident reports of 144 real-life cyber attacks investigated by its Rapid Response team during 2021.

What they found might not surprise you, but it’s vital information nevertheless, because it’s what really happened, not merely what might have.

Notably:

  • Unpatched vulnerabilities were the entry point for close to 50% of the attackers.

  • Attackers stuck around for more than a month on average when ransomware wasn’t their primary goal.

  • Attackers were known to have stolen data in about 40% of incidents. (Not all data thefts can be proved, of course, given that there isn’t a gaping hole where your copy of the data used to be, so the true number could be much higher.)

  • RDP was abused to circumnavigate the network by more than 80% of attackers once they’d broken in.

Intriguingly, if perhaps unsurprisingly, the smaller the organisation, the longer the crooks had generally been in the network before anyone noticed and decided it was time to kick them out.

In businesses with 250 staff and below, the crooks stuck around (in the jargon, this is known by the quaintly archaic automotive metaphor of dwell time) for more than seven weeks on average.

This compared with an average dwell time of just under three weeks for organisations with more than 3000 employees.

As you can imagine, however, ransomware criminals typically stayed hidden for much shorter periods (just under two weeks, instead of just over a month), not least because ransomware attacks are inherently self-limiting.

After all, once ransomware crooks have scrambled all your data, they’re out of hiding and straight into their in-your-face blackmail phase.

  • Small Businesses Struggle with an Increase in Cyber Attacks

Part of the problem: They don’t believe they are targets, so they don’t make security a priority. Cyber attacks are becoming more common for small businesses, and many aren’t prepared to deal with an attack.

As small businesses have accelerated their adoption of new technologies for remote work, communication, production and sales during the pandemic, their expanded computer networks have created new vulnerabilities to phishing and ransomware attacks. But many small businesses still don’t expect to be targeted by hackers, so preparing for a cyber attack is well down their list of priorities.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

Double Extortion Ransomware Victims Soar 935%

Researchers have recorded a 935% year-on-year increase in double extortion attacks, with data from over 2300 companies posted onto ransomware extortion sites.

Group-IB’s Hi-Tech Crime Trends 2021/2022 report covers the period from the second half of 2020 to the first half of 2021.

During that time, an “unholy alliance” of initial access brokers and ransomware-as-a-service (RaaS) affiliate programs has led to a surge in breaches, it claimed.

In total, the number of breach victims on ransomware data leak sites surged from 229 in the previous reporting period to 2371, Group-IB noted. During the same period, the number of leak sites more than doubled to 28, and the number of RaaS affiliates increased 19%, with 21 new groups discovered.

Group-IB warned that, even if victim organisations pay the ransom, their data often end up on these sites.

MI6 Boss: Digital Attack Surface Growing "Exponentially"

Head of the Secret Intelligence Service (SIS), Richard Moore, explained in a rare speech this week that, unlike the character Q from the James Bond films, even MI6 cannot source all of its tech capabilities in-house.

New partners and tech capabilities will help address MI6’s four key priorities: Russia, China, Iran and global terrorism. It’s a challenge made more acute as technology rapidly advances, he said.

“The ‘digital attack surface’ that criminals, terrorists and hostile states threats seek to exploit against us is growing exponentially. We may experience more technological progress in the next ten years than in the last century, with a disruptive impact equal to the industrial revolution,” Moore argued.

How Phishing Kits Are Enabling A New Legion Of Pro Phishers

Some cybercriminals are motivated by political ideals, others by malice or mischief, but most are only interested in cold, hard cash. To ensure their criminal endeavours are profitable, they need to balance the potential payday against the time, resources and risk required.

It’s no wonder then that so many use phishing as their default attack method. Malicious emails can be used to reach many targets with relative ease, and criminals can purchase ready-made phishing kits that bundle together everything they need for a lucrative campaign.

Crooks Are Selling Access To Hacked Networks. Ransomware Gangs Are Their Biggest Customers

Dark web forum posts offering compromised VPN, RDP credentials and other ways into networks have tripled in the last year.

There's been a surge in cyber criminals selling access to compromised corporate networks as hackers look to cash in on the demand for vulnerable networks from gangs looking to initiate ransomware attacks.

Researchers at cybersecurity company Group-IB analysed activity on underground forums and said there's been a sharp increase in the number of offers to sell access to compromised corporate networks, with the number of posts offering access tripling between 2020 and 2021

Omicron Phishing Scam Already Spotted in UK

The global pandemic has provided cover for all sorts of phishing scams over the past couple of years, and the rise in alarm over the spread of the latest COVID-19 variant, Omicron, is no exception.

As public health professionals across the globe grapple with what they fear could be an even more dangerous COVID-19 variant than Delta, threat actors have grabbed the opportunity to turn uncertainty into cash.

UK consumer watchdog “Which?” has raised the alarm that a new phishing scam, doctored up to look like official communications from the National Health Service (NHS), is targeting people with fraud offers for free PCR tests for the COVID-19 Omicron variant

Phishing Remains the Most Common Cause of Data Breaches, Survey Says

Phishing, malware, and denial-of-service attacks remained the most common causes for data breaches in 2021. Data from Dark Reading’s latest Strategic Security Survey shows that more companies experienced a data breach over the past year due to phishing than any other cause. The percentage of organisations reporting a phishing-related breach is slightly higher in the 2021 survey (53%) than in the 2020 survey (51%). The survey found that malware was the second biggest cause of data breaches over the past year, as 41% of the respondents said they experienced a data breach where malware was the primary vector.

Ransomware Victims Increase Security Budgets Due To Surge In Attacks

As the end of 2021 approaches, there’s no doubt ransomware became a top cybersecurity concern across multiple industries.  Successful ransomware attacks like the Colonial Pipeline, which took down critical US infrastructure, and Kaseya, which hit over 1,500 companies in a single attack, became a popular topic in the news.

Research conducted by Cymulate, however, shows that despite the increase in the number of attacks this past year, overall victims suffered limited damage in both severity and duration. Potential victims have improved their level of preparedness, with 70% reporting an increase of awareness at the boardroom and business management level. The majority (55%) undertook proactive measures to prevent ransomware attacks before they could cause any significant damage, and many of those respondents (38%) prevented attacks even before they could cause any serious downtime. Only 14% of respondents that experienced an attack were down for a week or more.

Control Failures Are Behind A Growing Number Of Cyber Security Incidents

Data from a survey of 1,200 enterprise security leaders reveals that an increase in tools and manual reporting combined with control failures are contributing to the success of threats such as ransomware, which costs organisations an average of $1.85 million in recovery, according to Panaseer.

Currently, only 36% of security leaders feel very confident in their ability to prove controls were working as intended. This is despite 99% of respondents believing it’s valuable to know that all controls are fully deployed and operating within policy, and cybersecurity control failures are currently being listed as the top emerging risk in the latest Gartner Emerging Risks Monitor Report. Attacks only succeed when they hit systems that haven’t been patched or don’t have security controls monitoring them.

MI6 Spy Chief Says China, Russia, Iran Top UK Threat List

China, Russia and Iran pose three of the biggest threats to the U.K. in a fast-changing, unstable world, the head of Britain’s foreign intelligence agency said Tuesday.

MI6 chief Richard Moore said the three countries and international terrorism make up the “big four” security issues confronting Britain’s spies.

In his first public speech since becoming head of the Secret Intelligence Service, also known as MI6, in October 2020, Moore said China is the intelligence agency’s “single greatest priority” as the country’s leadership increasingly backs “bold and decisive action” to further its interests.

Calling China “an authoritarian state with different values than ours,” he said Beijing conducts “large-scale espionage operations” against the U.K. and its allies, tries to ”distort public discourse and political decision-making” and exports technology that enables a “web of authoritarian control” around the world.

Moore said the U.K. also continues “to face an acute threat from Russia.” He said Moscow has sponsored killing attempts, such as the poisoning of former spy Sergei Skripal in England in 2018, mounts cyber attacks and attempts to interfere in other countries’ democratic processes.
