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

75% of Organisations Worldwide Set to Ban ChatGPT and Generative AI Apps on Work Devices

Newly released research found that 75% of organisations worldwide are currently implementing or considering bans on ChatGPT and other generative Artificial Intelligence (AI) applications within the workplace, with 61% stating that it will be a long term or permanent solution. Despite this, the majority recognised the opportunity such applications bring to the workplace, with 55% believing it would increase efficiency. All in all, 81% remained in favour of AI, highlighting that whilst organisations see the benefit, they are not ready to take the plunge for fear of being caught flat-footed.

Many organisations may simply not have the expertise-in house or confidence to employ AI effectively. These organisations lack an effective AI management plan, which governs the usage of AI in the corporate environment, rather than banning it outright. By having a clear-set AI plan, organisations can use AI to improve their efficiency, whilst maintaining cyber resilience. An increasing number of organisations have approached us at Black Arrow to discuss how to embrace AI securely; contact us to see how we can help you.

How an Eight-Character Password Could be Cracked in Just a Few Minutes

Strong and complex passwords are necessary to protect online accounts and data from cyber criminals. Complex passwords typically use lowercase and uppercase characters, numbers, and special characters. But complexity by itself can still open your password to cracking if it doesn’t contain enough characters, according to research by security firm Hive Systems. The report found that a complex password of eight characters can be cracked in only five minutes, and other weaker or shorter passwords are cracked instantly. However, passwords that have a greater number of characters are less vulnerable: for example an 18 character password, even if only lowercase letters, would take 481,000 years for a computer to crack.

Since creating and remembering multiple complex and lengthy passwords on your own is impossible, a password manager is your best bet. By using a password manager for yourself or within your organisation, you can generate, store and apply strong passwords for websites and online accounts.

Ransomware Victims Surge 143% as Threat Actors Pivot to Zero-Day Exploits

The number of organisations that became victims of ransomware attacks surged 143% between the first quarter of 2022 and first quarter of this year, as attackers increasingly leveraged zero-day vulnerabilities to break into target networks.

In many of these attacks, threat actors did not bother to encrypt data belonging to victim organisations. Instead, they focused solely on stealing their sensitive data and extorting victims by threatening to sell or leak the data to others. The tactic left even those with otherwise robust backup and restoration processes backed into a corner; this highlights the need for organisations to be able to detect and ideally block anomalous exfiltration of data, and have effective and rehearsed incident response plans to address the concept of pure exfiltration, because having backups is not enough.

The costs of these types of controls continue to fall making them viable for even smaller businesses. Without tools like Managed Detection and Response (MDR) and Data Loss Prevention (DLP), attacks of this nature cannot be detected until it is too late to do anything to stop them.

How Executives’ Personal Devices Threaten Business Security

Individuals, including executives, are considered a major target for cyber attacks. Motivated attackers know the right individual people they want to go after to achieve their larger organisational goal, and they’ll use any means necessary to be successful.

A recent report found that most executives are using their personal devices for work, creating a “backdoor” for cyber criminals to access large organisations. 50% of executive respondents reported receiving work-related scams in their personal emails.

Personal device use can be effective for organisations, however they need to implement an effective bring-your-own-device (BYOD) procedure and provide employees, including executives, with frequent user awareness and education training. All users at all levels within an organisation need to understand the risks, and importantly the role they play in keeping the organisation secure.

77% of Financial Firms Saw an Increase in Cyber Attack Frequency

According a recent report on the financial services sector, 77% of firms reported an increase in attack frequency, and 87% said attacks were more severe. These firms unanimously said they would look to outsource their cyber security programs to third-party providers to shore up their cyber defences. Among the respondents, firms need to protect hybrid work environments (62%), consolidate cyber security and managed IT services (41%) and tap industry-specific and regulatory expertise (33%).

Protecting Against Sophisticated Cyber Attacks Requires Layered Defences

Faced with an influx of sophisticated cyber threats, including usage of AI to further enhance the efficacy of social engineering attacks, and the growth of both malware-as-a-service (MaaS) and ransomware-as-a-service (RaaS), it is critical for organisations to invest in layered security defences.

Services like managed detection and response (MDR) are integral to monitoring, investigating and responding to threats in real time. But without a strong and comprehensive foundational cyber security posture, managed services alone cannot effectively mitigate threats. To ensure comprehensive defences against emerging threats, organisations must prioritise proactive measures that can stop attacks before they even start. As adversaries continue to refine their attack techniques, layered protection that covers every stage in the attack chain becomes imperative.

Managing Human Cyber Risks Matters Now More Than Ever

As artificial intelligence (AI) amplifies the sophistication and reach of phishing, vishing, and smishing attacks, understanding and managing human cyber risks has become increasingly vital, according to the SANS Institute. It makes sense as no matter the technological advancement, the human element has always been a point of entry for attackers.

A recent study found that mature security programs, marked by robust teams and leadership support, are characterised by having at least three full-time employees in their security awareness teams. In some cases, this isn’t feasible for an organisation and this is where outsourcing comes in. By outsourcing security awareness, organisations can ensure that they have access to security awareness experts, to keep their organisation educated. Here at Black Arrow we offer regular security and awareness training, bespoke to your organisation, for your employees and leadership team.

Hackers are Targeting Top Executives’ Microsoft 365 Accounts to Steal Work Logins

Cyber security provider Proofpoint reported that high-level execs at some of the world’s leading companies are repeatedly targeted with credential-stealing attacks. More alarmingly, according to Proofpoint, around one-third (35%) of the compromised users had multi-factor authentication (MFA) enabled.

The attacks come amid a rise in cases of EvilProxy, a phishing tool that allows attackers to steal even MFA-protected credentials. In the three months to June 2023, around 120,000 EvilProxy phishing emails were observed being sent to hundreds of targeted organisations globally, with many targeting Microsoft 365 user accounts in particular. Approximately 39% of the victims were C-level executives of which 17% were Chief Financial Officers, and 9% were Presidents and CEOs. Users must be trained effectively, to help mitigate the chance of them suffering a phishing attack. The C-suite is no exception.

UK Shaken by Major Data Breaches

Recent major data breaches impacting crucial institutions like the UK Electoral Commission (which exposed the data of 40 million UK voters) and the Police Service of Northern Ireland, have brought attention to potential risks. Following a recent freedom of information request 10,000 police officers and staff details where published including details such as first name and surname, their rank or grade and the unit and where they are based. This breach occurred when a junior member of staff forgot to remove the master spreadsheet containing sensitive data when responding to the request.

Threat of Cyber Attacks to UK National Security Upgraded: Compared to Chemical Weapons or Nuclear Attack

The UK government has raised the threat level posed by cyber attacks, now deeming the risk of cyber attacks to be more severe than that presented by small-scale chemical, biological, radiological, or nuclear (CBRN) attacks according to the latest National Risk Register (NRR) report for 2023. The report also highlighted artificial intelligence (AI) as a “chronic risk” – that is, one that poses “continuous challenges that erode our economy, community, way of life, and/or national security”.

Mac Users are Facing More Dangerous Security Threats Than Ever Before

Apple’s MacBook Pro or iPhone devices are often perceived as safer, from a cyber security standpoint, compared to those from Microsoft or Google, mostly because of its “walled garden” approach. However, another key reason why hackers were not historically as interested in Apple was the smaller market share Apple held. That is no longer the case and as attacks are rising against Apple devices, this is something we expect to see continuing to accelerate.

In the last 10 years, Apple’s market share on desktop has increased from less than 7.5% to just over 20% today. Apple frequently patches actively exploited vulnerabilities, with overall 261 security vulnerabilities addressed so far this year. A recent report found that Mac users are targeted by three key threats: Trojans, Adware, and Potentially Unwanted Applications (PUA). Of the three, Trojans are the biggest single threat, making up more than half of all threat detections. Of all those detections, around half (52.7%) were for the EvilQuest encryption malicious software.

Cyber Attack to Cost Outsourcing Firm Capita up to £25m

Capita expects to take a financial hit of as much as £25m as a result of a cyber attack that began in March, pushing the outsourcing group to a pre-tax loss of almost £68m for the first half of the year. The group is still recovering from the attack by the Black Basta ransomware group, which hacked its Microsoft Office 365 software and accessed the personal data of staff working for the company and dozens of clients. Capita, which runs crucial services for local councils, the military, and the NHS, estimated that the financial costs associated with what it called the “cyber incident” would be between £20m and £25m. Previous estimates had put the cost at £15m to £20m.

The group said this new figure reflected the complexities of analysing the “exfiltrated” data, as well as costs of recovery and remediation and new investment to improve its cyber security. However, Capita said it was not currently able to estimate the level of any potential fine related to the incident and had not yet made any provision to cover any future costs. The company’s shares fell by more than 12% in morning trading on Friday after the release of its results, making it the biggest faller on the FTSE 250.

Government and Public Services Face 40% More Cyber Attacks and Struggle to Protect Due to Lack of Resources

A report published by BlackBerry noted a 40% rise in cyber attacks against public sector organisations and government institutions. One of the reasons is the limited resources and resistance that these government and public have; this makes it much easier for an attacker. An easy target is an attractive target.

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

  • How Confident Are Companies In Managing Their Current Threat Exposure?

Crossword Cybersecurity has released a report based on the findings of a survey of over 200 CISOs and senior UK cyber security professionals. The paper reveals companies are more concerned and exposed to cyber threats than ever before, with 61 percent describing themselves as at best only “fairly confident” at managing their current cyber security threat exposure, which should raise some eyebrows around the boardroom.

Respondents also feared their cyber strategy would not keep pace with the rate of tech innovation and changes in the threat landscape. 40 percent of organisations believe their existing cyber strategy will be outdated in two years, and a further 37 percent within three years. Additional investment is needed to address longer term planning, with 44 percent saying they only have sufficient resources in their organisation to focus on the immediate and mid-term cyber threats and tech trends.

  • 'There's No Ceiling': Ransomware's Alarming Growth Signals A New Era, Verizon DBIR Finds

Ransomware has become so efficient, and the underground economy so professional, that traditional monetisation of stolen data may be on its way out.

The past year has seen a staggering acceleration in ransomware incidents, with 25% of all breaches containing a ransomware component.

That's the top-line finding in the 2022 Verizon Data Breach Investigations Report (DBIR), which found that ransomware events in conjunction with breaches ballooned 13% in the past year — last year's report found that just 12% of incidents were ransomware-related. That translates into a rate of increase that's more than the previous five years of growth combined.

The 15th annual DBIR analysed 23,896 security incidents, of which 5,212 were confirmed breaches. About four in five of those were the handiwork of external cyber criminal gangs and threat groups, according to Verizon. And according to Alex Pinto, manager of the Verizon Security Research team, these nefarious types are finding it easier and easier to earn an ill-gotten living with ransomware, making other types of breaches increasingly obsolete.

"Everything in cyber crime has become so commoditised, so much like a business now, and it's just too darn efficient of a methodology for monetising their activity," he tells Dark Reading, noting that with the emergence of ransomware as-a-service (RaaS) and initial-access brokers, it takes very little skill or effort to get into the extortion game.

"Before, you had to get in somehow, look around, and find something worth stealing that would have a reseller on the other end," he explains. "In 2008 when we started the DBIR, it was by and large payment-card data that was stolen. Now, that has fallen precipitously because they can just pay for access someone else established and install rented ransomware, and it's so much simpler to reach the same goal of getting money."

  • Paying Ransom Doesn’t Guarantee Data Recovery

A Veeam report has found that 72% of organisations had partial or complete attacks on their backup repositories, dramatically impacting the ability to recover data without paying the ransom.

Additionally, 76% of organisations admitted to paying the ransom. But while 52% paid the ransom and were able to recover data, 24% paid the ransom but were still not able to recover data.

https://www.helpnetsecurity.com/2022/05/24/paying-ransom-recover-data-video/

  • Report: Frequency Of Cyber Attacks in 2022 Has Increased By Almost 3M

Kaspersky has released a new report revealing a growing number of cyber attacks on small businesses in 2022 so far. Researchers compared the period between January and April 2022 to the same period in 2021, finding increases in the numbers of Trojan-PSW detections, internet attacks and attacks on Remote Desktop Protocol.

In 2022, the number of Trojan-PSW (Password Stealing Ware) detections increased globally by almost a quarter compared to the same period in 2021 一 4,003,323 to 3,029,903. Trojan-PSW is a malware that steals passwords, along with other account information, which then allows attackers to gain access to the company network and steal sensitive information.

Internet attacks grew from 32,500,000 globally in the analysed period of 2021 to almost 35,400,000 in 2022. These can include web pages with redirects to exploits, sites containing exploits and other malicious programs, botnet command & control centres and more.

The number of attacks on Remote Desktop Protocol grew in the U.S. (while dropping slightly globally), going from 47.5 million attacks in the first trimester of 2021 to 51 million in the same period of 2022. With the widespread shift toward remote work, many companies have introduced Remote Desktop Protocol (RDP), a technology that enables computers on the same corporate network to be linked together and accessed remotely, even when the employees are at home.

With small business owners typically handling numerous responsibilities at the same time, cyber security is often an afterthought. However, this disregard for IT security is being exploited by cyber criminals. The Kaspersky study sought to assess the threats that pose an increasing danger to entrepreneurs.

  • New Zoom Flaws Could Let Attackers Hack Victims Just By Sending Them A Message

Popular video conferencing service Zoom has resolved as many as four security vulnerabilities, which could be exploited to compromise another user over chat by sending specially crafted Extensible Messaging and Presence Protocol (XMPP) messages and execute malicious code.

With Zoom's chat functionality built on top of the XMPP standard, successful exploitation of the issues could enable an attacker to force a vulnerable client to masquerade a Zoom user, connect to a malicious server, and even download a rogue update, resulting in arbitrary code execution stemming from a downgrade attack.

  • VMware, Airline Targeted As Ransomware Chaos Reigns

Global ransomware incidents target everything from enterprise servers to grounding an airline, with one India-based group even taking a Robin Hood approach to extortion with the "GoodWill" strain.

Ransomware incidents are on the rise and this week proved no exception, with the discovery of a Linux-based ransomware family called Cheerscrypt targeting VMware ESXi servers and an attack on SpiceJet, India’s second largest airline.

Meanwhile, an oddball "GoodWill" variant purports to help the needy.

The Cheerscrypt ransomware variant was uncovered by Trend Micro and relies on the double-extortion scheme to coerce victims to pay the ransom – i.e., stealing data as well and threatening to leak it if victims don’t pay up.

Because of the popularity of ESXi servers for creating and running multiple virtual machines (VMs) in enterprise settings, the Cheerscrypt ransomware could be appealing to malicious actors looking to rapidly distribute ransomware across many devices.

Meanwhile, low-cost carrier SpiceJet faced a ransomware attack this week, causing flight delays of between two and five hours as well as rendering unavailable online booking systems and customer service portals.

While the company’s IT team announced on Twitter that it had successfully prevented the attempted attack before it was able to fully breach all internal systems and take them over, customers and employees are still experiencing the ramifications.

  • Crypto Hacks Aren't A Niche Concern; They Impact Wider Society

Million-dollar crypto heists are becoming more common as the currency starts to go mainstream; prevention and enforcement haven't kept pace.

The attack against the Ronin Network in March was quickly speculated to be one of the largest cryptocurrency hacks of all time. Approximately $540 million was stolen from the cryptocurrency and NFT games company in a combination of USDC and Etherium, with $400 million of the stolen funds owned by customers playing the game Axie Infinity.

This attack was the latest in a string of thefts perpetrated against crypto and should be a jolt to both the digital asset and cyber security communities to bring the security of cryptocurrencies into line.

The current vogue of large-scale crypto heists goes as far back as the 2014 Mt. Gox hack (another cryptocurrency exchange built around a game, Magic: The Gathering), which went into bankruptcy after losing $460 million of assets.

However, the trend has been gathering pace. In the months leading up to the Ronin Network attack, cyber criminals stole nearly $200 million worth of cryptocurrency from the crypto trading platform BitMart, attacked 400 Crypto.com users, and orchestrated NFT-related scams, to name but a few incidents.

There is often an uncomfortable tendency to see these attacks as something that takes place in isolation in a remote part of the Internet when they actually have a huge impact on thousands of people.

  • State Of Cyber Security Report 2022 Names Ransomware And Nation-State Attacks As Biggest Threats

Ransomware is the biggest concern for cyber security professionals, according to results of the Infosecurity Group’s 2022 State of Cybersecurity Report, produced by Infosecurity Europe and Infosecurity Magazine.

Cyber Security Professionals' Number One Concern: Ransomware.

This attack vector was voted as the biggest cyber security trend (28%) by the survey respondents (including CISOs, CTOs, CIOs and academics), marking a significant change from the previous report in 2020, where ransomware did not break the top three. This follows surging ransomware incidents in 2021, with ransom demands and payments growing significantly last year. A number of these attacks have also impacted critical industries, for example, taking down the US’ largest fuel pipeline.

The survey respondents also highlighted the evolving tactics and capabilities of ransomware attackers. This includes threat actors becoming more sophisticated as they evolve into loosely coupled service-based operations.

A number of cyber security professionals believe that cyber-criminal groups will become more guarded in their approach due to new initiatives by governments and law enforcement to tackle these activities.

Cyber Security Professionals' Number Two Concern: Nation-State Attacks.

The second biggest concern for survey respondents was geopolitics/nation-state attacks (24%), particularly the shifting hostilities from the Russia-Ukraine conflict into cyberspace. Russia already had a reputation for conducting offensive cyber operations prior to the conflict, and the Ukrainian government and critical services have experienced numerous attacks both before and since the war began.

https://www.infosecurity-magazine.com/news/2022-state-industry-report/

  • Vishing (Voice Phishing) Cases Reach All Time High

Vishing (voice phishing) cases have increased almost 550 percent over the last twelve months (Q1 2021 to Q1 2022), according to the latest Quarterly Threat Trends & Intelligence Report from Agari and PhishLabs.

In Q1 2022, Agari and PhishLabs detected and mitigated hundreds of thousands of phishing, social media, email, and dark web threats targeting a broad range of enterprises and brands. The report provides an analysis of the latest findings and insights into key trends shaping the threat landscape.

According to the findings, vishing attacks have overtaken business email compromise (BEC) as the second most reported response-based email threat since Q3 2021. By the end of the year, more than one in four of every reported response-based threat was a vishing attack, and this makeup continued through Q1 2022.

https://www.helpnetsecurity.com/2022/05/24/vishing-cases-increased/

  • DeFi (Decentralised Finance) Is Getting Pummelled By Cyber Criminals

Decentralised finance lost $1.8 billion to cyber attacks last year — and 80% of those events were the result of vulnerable code, analysts say.

Decentralised finance (DeFi) platforms — which connect various cryptocurrency blockchains to create a decentralised infrastructure for borrowing, trading, and other transactions — promise to replace banks as a secure and convenient way to invest in and spend cryptocurrency. But in addition to attracting hordes of new users with dreams of digital fortune, cyber criminals have discovered them to be an easy target, wiping out wallets to zero balances in a moment, tanking whole markets while profiting, and more, according to a new report.

Analysts with Bishop Fox found that DeFi platforms lost $1.8 billion to cyber attacks in 2021 alone. With a total of 65 events observed, 90% of the losses came from unsophisticated attacks, according to the report, which points to the lax cyber security practices of the sector.

DeFi averaged five attacks per week last year, with most of them (51%) coming from the exploitation of "smart contracts" bugs, the analysts found. Smart contracts are essentially records of transactions, stored on the blockchain.

Other top DeFi attack vectors include cryptowallets, protocol design flaws, and so-called "rug-pull" scams (where investors are lured to a new cryptocurrency project that is then abandoned, leaving targets with a worthless currency). But taken together, 80% of all events were caused by the use (and re-use) of buggy code, according to the report.
