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.

https://www.infosecurity-magazine.com/news/exploit-activity-150-q2-log4shell/

  • 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.

https://www.securityweek.com/realtek-sdk-vulnerability-exposes-routers-many-vendors-remote-attacks

  • 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.

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

  • Morgan Stanley Client Accounts Breached in Social Engineering Attacks

Morgan Stanley Wealth Management says some of its customers had their accounts compromised in social engineering attacks.

The account breaches were the result of vishing (aka voice phishing), a social engineering attack where scammers impersonate a trusted entity (in this case Morgan Stanley) during a voice call to convince their targets into revealing sensitive information such as banking or login credentials.

The company said in a notice sent to affected clients that, "on or around February 11, 2022," a threat actor impersonating Morgan Stanley gained access to their accounts after tricking them into providing their Morgan Stanley Online account info.

After successfully breaching their accounts, the attacker also electronically transferred money to their own bank account by initiating payments using the Zelle payment service.

https://www.bleepingcomputer.com/news/security/morgan-stanley-client-accounts-breached-in-social-engineering-attacks/

  • Ransomware Is Scary, But Another Scam Is Costing Victims Much, Much More

Business email compromise (BEC) remains the biggest source of financial losses, which totalled $2.4 billion in 2021, up from an estimated $1.8 billion in 2020, according to the Federal Bureau of Investigation's (FBI) Internet Crime Center (IC3).

The FBI says in its 2021 annual report that Americans last year lost $6.9 billion to scammers and cyber criminals through ransomware, BEC, and cryptocurrency theft related to financial and romance scams. In 2020, that figure stood at $4.2 billion.

Last year, FBI's Internet Crime Complaint Center (IC3) received 847,376 complaints about cybercrime losses, up 7% from 791,790 complaints in 2020.

BEC has been the largest source of fraud for several years despite ransomware attacks grabbing most headlines.

  • Phishing Kits Constantly Evolve to Evade Security Software

Modern phishing kits sold on cybercrime forums as off-the-shelf packages feature multiple, sophisticated detection avoidance and traffic filtering systems to ensure that internet security solutions won’t mark them as a threat.

Fake websites that mimic well-known brands are abundant on the internet to lure victims and steal their payment details or account credentials.

Most of these websites are built using phishing kits that feature brand logos, realistic login pages, and in cases of advanced offerings, dynamic webpages assembled from a set of basic elements.

https://www.bleepingcomputer.com/news/security/phishing-kits-constantly-evolve-to-evade-security-software/

  • Ransomware Payment Demands Rose Dramatically in 2021

Ransomware attackers demanded dramatically higher ransom fees last year, and the average ransom payment rose by 78% to $541,010, according to data from incident response (IR) cases investigated by Palo Alto Networks Unit 42.

IR cases by Unit 42 also saw a whopping 144% increase in ransom demands, to $2.2 million. According to the report, the most victimised sectors were professional and legal services, construction, wholesale and retail, healthcare, and manufacturing.

Cyber extortion spiked, with 85% of ransomware victims — some 2, 556 organisations — having their data dumped and exposed on leak sites, according to the "2022 Unit 42 Ransomware Threat Report."

Conti led the ransomware attack volume, representing some one in five cases Unit 42 investigated, followed by REvil, Hello Kitty, and Phobos.

  • 7 Suspected Members of LAPSUS$ Hacker Gang, aged 16 to 21, Arrested in UK

The City of London Police has arrested seven teenagers between the ages of 16 and 21 for their alleged connections to the prolific LAPSUS$ extortion gang that's linked to a recent burst of attacks targeting NVIDIA, Samsung, Ubisoft, LG, Microsoft, and Okta.

"The City of London Police has been conducting an investigation with its partners into members of a hacking group," Detective Inspector, Michael O'Sullivan, said in a statement shared with The Hacker News. "Seven people between the ages of 16 and 21 have been arrested in connection with this investigation and have all been released under investigation. Our enquiries remain ongoing."

The development, which was first disclosed by BBC News, comes after a report from Bloomberg revealed that a 16-year-old Oxford-based teenager is the mastermind of the group. It's not immediately clear if the minor is one among the arrested individuals. The said teen, under the online alias White or Breachbase, is alleged to have accumulated about $14 million in Bitcoin from hacking.

  • Here's How Fast Ransomware Encrypts Files

Forty-two minutes and 54 seconds: that's how quickly the median ransomware variant can encrypt and lock out a victim from 100,000 of their files.

The data point came from Splunk's SURGe team, which analysed in its lab how quickly the 10 biggest ransomware strains — Lockbit, REvil, Blackmatter, Conti, Ryuk, Avaddon, Babuk, Darkside, Maize, and Mespinoza — could encrypt 100,000 files consisting of some 53.93 gigabytes of data. Lockbit won the race, with speeds of 86% faster than the median. One Lockbit sample was clocked at encrypting 25,000 files per minute.

Splunk's team found that ransomware variants are all over the map speed-wise, and the underlying hardware can dictate their encryption speeds.

  • HEAT Attacks: A New Class of Cyber Threats Organisations Are Not Prepared For

Web malware (47%) and ransomware (42%) now top the list of security threats that organisations are most concerned about. Yet despite the growing risks, just 27% have advanced threat protection in place on every endpoint device that can access corporate applications and resources.

This is according to research published by Menlo Security, exploring what steps organisations are taking to secure themselves in the wake of a new class of cyber threats – known as Highly Evasive Adaptive Threats (HEAT).

As employees spend more time working in the browser and accessing cloud-based applications, the risk of HEAT attacks increases. Almost two-thirds of organisations have had a device compromised by a browser-based attack in the last 12 months. The report suggests that organisations are not being proactive enough in mitigating the risk of these threats, with 45% failing to add strength to their network security stack over the past year. There are also conflicting views on the most effective place to deploy security to prevent advanced threats, with 43% citing the network, and 37% the cloud.

  • The Cyber Warfare Predicted in Ukraine May Be Yet to Come

In the build-up to Russia’s invasion of Ukraine, the national security community braced for a campaign combining military combat, disinformation, electronic warfare and cyber attacks. Vladimir Putin would deploy devastating cyber operations, the thinking went, to disable government and critical infrastructure, blind Ukrainian surveillance capabilities and limit lines of communications to help invading forces. But that’s not how it has played out. At least, not yet.

The danger is that as political and economic conditions deteriorate, the red lines and escalation judgments that kept Moscow’s most potent cyber capabilities in check may adjust. Western sanctions and lethal aid support to Ukraine may prompt Russian hackers to lash out against the west. Russian ransomware actors may also take advantage of the situation, possibly resorting to cyber crime as one of the few means of revenue generation.

  • The Three Russian Cyber Attacks the West Most Fears

The UK's cyber authorities are supporting the White House's calls for "increased cyber-security precautions", though neither has given any evidence that Russia is planning a cyber-attack.

Russia has previously stated that such accusations are "Russophobic".

However, Russia is a cyber-superpower with a serious arsenal of cyber-tools, and hackers capable of disruptive and potentially destructive cyber-attacks.

Ukraine has remained relatively untroubled by Russian cyber-offensives but experts now fear that Russia may go on a cyber-offensive against Ukraine's allies.

"Biden's warnings seem plausible, particularly as the West introduced more sanctions, hacktivists continue to join the fray, and the kinetic aspects of the invasion seemingly don't go to plan," says Jen Ellis, from cyber-security firm Rapid7.

This article from the BCC outlines the hacks that experts most fear, and they are repeats of things we have already seen coming out of Russia, only potentially a lot more destructive this time around.

https://www.bbc.co.uk/news/technology-60841924

  • Do These 8 Things Now to Boost Your Security Ahead of Potential Russian Cyber Attacks

The message comes as the US Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) ramp up warnings about Russian hacking of everything from online accounts to satellite broadband networks. CISA's current campaign is called Shields Up, which urges all organisations to patch immediately and secure network boundaries. This messaging is being echoed by UK and other Western Cyber authorities:

The use of Multi-Factor Authentication (MFA) is being very strongly advocated. The White House and other agencies both sides of the Atlantic also urged companies to take seven other steps:

  • Deploy modern security tools on your computers and devices to continuously look for and mitigate threats

  • Make sure that your systems are patched and protected against all known vulnerabilities, and change passwords across your networks so that previously stolen credentials are useless to malicious actors

  • Back up your data and ensure you have offline backups beyond the reach of malicious actors

  • Run exercises and drill your emergency plans so that you are prepared to respond quickly to minimize the impact of any attack

  • Encrypt your data so it cannot be used if it is stolen

  • Educate your employees to common tactics that attackers will use over email or through websites

  • Work with specialists to establish relationships in advance of any cyber incidents.

  • Cyber Crime Victims Suffered Losses of Over $6.9B in 2021 in the US Alone

The FBI's Internet Crime Complaint Center (IC3) reported a record-breaking year for 2021 in the number of complaints it received, among which business email compromise (BEC) attacks made up the majority of incidents.

IC3 handled 847,376 complaint reports last year — an increase of 7% over 2020 — which mainly revolved around phishing attacks, nonpayment/nondelivery scams, and personal data breaches. Overall, losses amounted to more than $6.9 billion.

BEC and email account compromises ranked as the No. 1 attack, accounting for 19,954 complaints and losses of around $2.4 billion.

"In 2021, heightened attention was brought to the urgent need for more cyber incident reporting to the federal government. Cyber incidents are in fact crimes deserving of an investigation, leading to judicial repercussions for the perpetrators who commit them," Paul Abbate, deputy director of the FBI wrote in the IC3's newly published annual report.

  • Expanding Threat Landscape: Cyber Criminals Attacking from All Sides

Research from Trend Micro warns of spiralling risk to digital infrastructure and remote workers as threat actors increase their rate of attack on organisations and individuals.

“Attackers are always working to increase their victim count and profit, whether through quantity or effectiveness of attacks,” said Jon Clay, VP of threat intelligence at Trend Micro.

“Our latest research shows that while Trend Micro threat detections rose 42% year-on-year in 2021 to over 94 billion, they shrank in some areas as attacks became more precisely targeted.”

Ransomware attackers are shifting their focus to critical businesses and industries more likely to pay, and double extortion tactics ensure that they are able to profit. Ransomware-as-a-service offerings have opened the market to attackers with limited technical knowledge – but also given rise to more specialisation, such as initial access brokers who are now an essential part of the cybercrime supply chain.

Threat actors are also getting better at exploiting human error to compromise cloud infrastructure and remote workers. Trend Micro detected and prevented 25.7 million email threats in 2021 compared to 16.7 million in 2020, with the volume of blocked phishing attempts nearly doubling over the period. Research shows home workers are often prone to take more risks than those in the office, which makes phishing a particular risk.
