Top Cyber Stories of the Last Week

  • Russian Sanctions Instigator Lloyd's Possibly Hit by Cyber Attack

Lloyd’s of London, the London-based insurance market heavily involved in implementing sanctions against Russia, may have been hit by a cyber-attack. On Wednesday, October 5, 2022, the British insurance market revealed it had detected “unusual activity” on its systems and has turned off all external connectivity “as a precautionary measure.”

“We have informed market participants and relevant parties, and we will provide more information once our investigations have concluded,” said a Lloyd’s spokesperson.

The company did not comment on whether or not it has been contacted by hackers, if a ransom demand has been issued, or on the possible source of the attack.

However, the insurance market has been closely involved with the design and implementation of sanctions imposed on Russia in response to its invasion of Ukraine – a potential motive for the attack. Lloyd’s itself has confirmed it was working closely with British and international governments to implement such sanctions.

Around 100 insurance syndicates operate at Lloyd's.

Earlier in 2022, Lloyd’s instructed its 76 insurance syndicates to remove “nation-state-backed cyber attacks” from insurance policies by March 2023, as well as losses “arising from a war.”

  • Former Uber Security Chief Convicted of Covering Up Data Breach

Uber’s former head of security has been convicted of covering up a 2016 data breach at the rideshare giant, hiding details from US regulators and paying off a pair of hackers in return for their discretion.

The trial, closely watched in cyber security circles, is believed to be the first criminal prosecution of a company executive over the handling of a data breach.

Joe Sullivan, who was fired in 2017 over the incident, was found guilty by a San Francisco jury of obstructing an investigation by the Federal Trade Commission. At the time of the 2016 breach, the regulator had been investigating the car-booking service over a different cyber security lapse that had occurred two years earlier.

Jurors also convicted Sullivan of a second count related to having knowledge of but failing to report the 2016 breach to the appropriate government authorities. The incident eventually became public in 2017 when Dara Khosrowshahi, who had just taken over as chief executive, disclosed details of the attack.

Prosecutors said Sullivan had taken steps to make sure data compromised in the attack would not be revealed. According to court documents, two hackers approached Sullivan’s team to notify Uber of a security flaw that exposed the personal information of almost 60mn drivers and riders on the platform.

  • First 72 Hours of Incident Response Critical to Taming Cyber Attack Chaos

Cyber security professionals tasked with responding to attacks experience stress, burnout, and mental health issues that are exacerbated by a lack of breach preparedness and sufficient incident response practice in their organisations.

A new IBM Security-sponsored survey published this week found that two-thirds (67%) of incident responders suffer stress and anxiety during at least some of their engagements, while 44% have sacrificed the well-being of their relationships, and 42% have suffered burnout, according to the survey conducted by Morning Consult. In addition, 68% of incidents responders often have to work on two or more incidents at the same time, increasing their stress, according to the survey's results.

Companies that plan and practice responding to a variety of incidents can lower the stress levels of their incident responders, employees, and executives, says John Dwyer, head of research for IBM Security's X-Force response team.

"Organisations are not effectively establishing their response strategies with the responders in mind — it does not need to be as stressful as it is," he says. "There is a lot of time when the responders are managing organisations during an incident, because those organisations were not prepared for the crisis that occurs. These attacks happen every day."

The IBM Security-funded study underscores why the cyber security community has focused increasingly on the mental health of its members. About half (51%) of cyber security defenders have suffered burnout or extreme stress in the past year, according to a VMware survey released in August 2021. Cyber security executives have also spotlighted the issue as one that affects the community and companies' ability to retain skilled workers.

  • Email Defences Under Siege: Phishing Attacks Dramatically Improve

This week's report that cyber attackers are laser-focused on crafting attacks specialised to bypass Microsoft's default security showcases an alarming evolution in phishing tactics, security experts said this week.

Threat actors are getting better at slipping phishing attacks through the weak spots in platform email defences, using a variety of techniques, such as zero-point font obfuscation, hiding behind cloud-messaging services, and delaying payload activation, for instance. They're also doing more targeting and research on victims.

As a result, nearly 1 in 5 phishing emails (18.8%) bypassed Microsoft's platform defences and landed in workers' inboxes in 2022, a rate that increased 74% compared to 2020, according to research published by cyber security firm Check Point Software. Attackers increasingly used techniques to pass security checks, such as Sender Policy Framework (SPF), and obfuscate functional components of an e-mail, such as using zero-size fonts or hiding malicious URLs from analysis.

The increasing capabilities of attackers is due to the better understanding of current defences, says Avanan, an email security firm acquired by Check Point in August 2021.

"It is a family of 10 to 20 techniques, but they all lead to the objective of deceiving a company's security layers," he says. "The end result is always an email that looks genuine to the recipient but looks different to the algorithm that analyses the content."

Microsoft declined to comment on the research. However, the company has warned of advanced techniques, such as adversary-in-the-middle phishing (AiTM), which uses a custom URL to place a proxy server between a victim and their desired site, allowing the attacker to capture sensitive data, such as usernames and passwords. In July, the company warned that more than 10,000 organisations had been targeted during one AiTM campaign.

  • Remote Services Are Becoming an Attractive Target for Ransomware

Stolen credentials are no longer the number one initial access vector for ransomware operators looking to infect a target network and its endpoints - instead, they’ve become more interested in exploiting vulnerabilities found in internet-facing systems.

A report from Secureworks claims ransomware-as-a-service developers are quick to add newly discovered vulnerabilities into their arsenals, allowing even less competent hackers to exploit them swiftly, and with relative ease.

In fact, the company's annual State of the Threat Report reveals that flaw exploitation in remote services accounted for 52% of all ransomware incidents the company analysed over the last 12 months.

Besides remote services, Secureworks also spotted a 150% increase in the use of infostealers, which became a “key precursor” to ransomware. Both these factors, the report stresses, kept ransomware as the number one threat for businesses of all sizes, “who must fight to stay abreast of the demands of new vulnerability prioritisation and patching”.

All things considered, ransomware is still the biggest threat for businesses. It takes up almost a quarter of all attacks that were reported in the last 12 months, Secureworks says, and despite law enforcement being actively involved, operators remained highly active.

  • Growing Reliance on Cloud Brings New Security Challenges

There was a time when cloud was just a small subset of IT infrastructure, and cloud security referred to a very specific set of tasks. The current reality is very different, organisations are heavily dependent on cloud technologies and cloud security has become a much more complex endeavour.

Organisations increasingly rely on the cloud to deliver new applications, reduce costs, and support business operations. One in every four organisations already have majority workloads in the cloud, and 44% of workloads currently run in some form of public cloud, says Omdia, a research and advisory group.

Practically every midsize and large organisation now operates in some kind of a hybrid cloud environment, with a mix of cloud and on-premises systems. For most organisations, software-as-a-service constitute the bulk (80%) of their cloud environments, followed by infrastructure-as-a-service and platform-as-a-service deployments.

In the past, cloud security conversations tended to focus on making sure cloud environments are being configured properly, but cloud security nowadays goes far beyond just configuration management. The sprawling cloud environment means security management has to be centralised, Omdia said. Security functions also need to be integrated into existing application deployment workflows.

On top of all of this, multicloud is becoming more common among organisations as they shift their workloads to avoid being dependent on a single platform. The three major cloud providers – Amazon Web Services, Microsoft Azure, and Google Cloud Platform – account for 65% of the cloud market.

  • Many IT Pros Don’t Think a Ransomware Attack Can Impact Microsoft 365 Data

The 2022 Ransomware Report, which surveyed over 2,000 IT leaders, revealed that 24% have been victims of a ransomware attack, with 20% of attacks happening in the last year.

Cyber attacks are happening more frequently. Last year’s ransomware survey revealed that 21% of companies experienced an attack. This year it rose by three percent to 24%.

“Attacks on businesses are increasing, and there is a shocking lack of awareness and preparation by IT pros. Our survey shows that many in the IT community have a false sense of security. As bad actors develop new techniques, companies like ours have to do what it takes to come out ahead and protect businesses around the world,” said Hornetsecurity.

The report highlighted a lack of knowledge on the security available to businesses. 25% of IT professionals either don’t know or don’t think that Microsoft 365 data can be impacted by a ransomware attack.

Just as worryingly, 40% of IT professionals that use Microsoft 365 in their organisation admitted they do not have a recovery plan in case their Microsoft 365 data was compromised by a ransomware attack.

“Microsoft 365 is vulnerable to phishing attacks and ransomware attacks, but with the help of third-party tools, IT admins can backup their Microsoft 365 data securely and protect themselves from such attacks,” said Hofmann.

  • Ransomware Group Bypasses "Enormous" Range of EDR Tools

A notorious ransomware group has been spotted leveraging sophisticated techniques to bypass endpoint detection and response (EDR) tools.

BlackByte, which the US government has said poses a serious threat to critical infrastructure, used a “Bring Your Own Driver” technique to circumvent over 1000 drivers used by commercially available EDR products, according to Sophos. The UK cyber security vendor explained in a new report that the group had exploited a known vulnerability, CVE-2019-16098, in Windows graphics utility driver RTCorec6.sys. This enabled it to communicate directly with a victim system’s kernel and issue commands to disable callback routines used by EDR tools.

The group also used EDR bypass techniques borrowed from open source tool EDRSandblast to deactivate the Microsoft-Windows-Threat-Intelligence ETW (Event Tracing for Windows) provider. This is a Windows feature “that provides logs about the use of commonly maliciously abused API calls such as NtReadVirtualMemory to inject into another process’s memory,” explained Sophos. Neutralising it in this way renders any security tool relying on the feature also useless, the firm argued.

“If you think of computers as a fortress, for many EDR providers, ETW is the guard at the front gate,” said Sophos. “If the guard goes down, then that leaves the rest of the system extremely vulnerable. And, because ETW is used by so many different providers, BlackByte’s pool of potential targets for deploying this EDR bypass is enormous.”

BlackByte is not the only ransomware group using these advanced techniques to get around existing detection tools, illustrating the continued arms race between attackers and defenders. AvosLocker used a similar method in May, Sophos said. “Anecdotally, from what we’re seeing in the field, it does appear that EDR bypass is becoming a more popular technique for ransomware threat groups,” the firm confirmed. “This is not surprising. Threat actors often leverage tools and techniques developed by the ‘offensive security’ industry to launch attacks faster and with minimal effort.”

  • MS Exchange Zero-Days: The Calm Before the Storm?

Two exploited MS Exchange zero-days that still have no official fix, have been added to CISA’s Known Exploited Vulnerabilities (KEV) Catalog.

But mitigating the risk of exploitation until patches are ready will require patience and doggedness, as Microsoft is still revising its advice to admins and network defenders, and still working on the patches.

The two vulnerabilities were publicly documented last Wednesday, by researchers with Vietnamese company GTSC, and Microsoft soon after sprung into (discernible) action by offering customer guidance, followed by an analysis of the attacks exploiting the two vulnerabilities. Several changes have been made to the documents since then, after the company found and other researchers pointed out several shortcomings.

Microsoft says its threat analysts observed “activity related to a single activity group in August 2022 that achieved initial access and compromised Exchange servers by chaining CVE-2022-41040 and CVE-2022-41082 in a small number of targeted attacks,” and that the attackers breached fewer than 10 organisations globally. “MSTIC assesses with medium confidence that the single activity group is likely to be a state-sponsored organisation,” they added.

The other good news is there are still no public exploits for the two vulnerabilities. But, Microsoft says, “Prior Exchange vulnerabilities that require authentication have been adopted into the toolkits of attackers who deploy ransomware, and these vulnerabilities are likely to be included in similar attacks due to the highly privileged access Exchange systems confer onto an attacker.”

Enterprise defenders should expect trouble via this attack path in the near future, it seems, so keeping abreast of the changing situation and springing into action as quickly as possible once the patches are made available is advised. Scammers have since started impersonating security researchers and offering non-existing PoC exploits for CVE-2022-41082 for sale via GitHub

  • Average Company with Data in the Cloud Faces $28 Million in Data-Breach Risk

Hard-to-control collaboration, complex SaaS permissions, and risky misconfigurations — such as admin accounts without multi-factor authentication (MFA) — have left a dangerous amount of cloud data exposed to insider threats and cyber attacks, according to Varonis.

For the report, researchers analysed nearly 10 billion cloud objects (more than 15 petabytes of data) across a random sample of data risk assessments performed at more than 700 companies worldwide. In the average company, 157,000 sensitive records are exposed to everyone on the internet by SaaS sharing features, representing $28 million in data-breach risk, Varonis researchers have found.

One out of every 10 records in the cloud is exposed to all employees — creating an impossibly large internal blast radius, which maximises damage during a ransomware attack. The average company has 4,468 user accounts without MFA enabled, making it easier for attackers to compromise internally exposed data.

Out of 33 super admin accounts in the average organisation, more than half did not have MFA enabled. This makes it easier for attackers to compromise these powerful accounts, steal more data, and create backdoors. Companies have more than 40 million unique permissions across SaaS applications, creating a nightmare for IT and security teams responsible for managing and reducing cloud data risk.

“Cloud security shouldn’t be taken for granted. When security teams lack critical visibility to manage and protect SaaS and IaaS apps and services, it’s nearly impossible to ensure your data isn’t walking out the door,” said Varonis. “This report is a true-to-life picture of over 700 real-world risk assessments of production SaaS environments. The results underscore the urgent need for CISOs to uncover and remediate their cloud risk as quickly as possible.”

  • Secureworks Finds Network Intruders See Little Resistance

Attackers who break into networks only need to take a few basic measures in order to avoid detection.

Security vendor Secureworks said in its annual State of the Threat report that it observed several data breaches between June 2021 and June 2022 and found that, by and large, once network intruders gained a foothold on the targets' environment, they had to do relatively little to stay concealed.

"One thing that is notable about them is that none of these techniques are particularly sophisticated," the vendor said. "That is because threat actors do not need them to be; the adversary will only innovate enough to achieve their objectives. So there is a direct relationship between the maturity of the controls in a target environment and the techniques they employ to bypass those controls."

Among the more basic measures taken by the attackers was coding their tools in newer languages such as Go or Rust. This tweak created enough of a difference in the software to evade signature-checking tools, according to Secureworks' report. In other cases, the network intruders hid their activity by packing their malware within a trusted Windows installer or by sneaking it into the Authenticode signature of a trusted DLL. In another case, a malware infection was seen moving data out of the victim's network via TOR nodes. While effective, Secureworks said the techniques are hardly innovative. Rather, they indicate that threat actors find themselves only needing to do the bare minimum to conceal themselves from detection.

  • Regulations, Laws and Accountability are Changing the Cyber Security Landscape

As cyber criminals continue to develop new ways to wreak havoc, regulators have been working to catch up. They aim to protect data and consumers while avoiding nation-state attacks that are a risk to national and economic security. But some of these regulations may provide an opportunity for MSSPs.

Some of these regulations are a response to what’s generally been a hands-off approach to telling organisations what to do. Unfortunately, cyber security isn’t always prioritised when budgets and resources are allocated. The result is a steadily rising tide of breaches and exploits that have held organisations hostage and made private information available on the dark web.

The new regulations are coming from all directions: at the state and federal levels in the US and around the world. While many of these regulations aren’t yet final, there’s no reason not to start aligning with where trends will ease the impact of changing rules. At the same time, many organisations want to hold the government responsible for some kinds of attacks. It will be interesting to see how regulating works, as most politicians and bureaucrats aren’t known for their technological savvy.

In the US, for example, new regulations are in development in the Federal Trade Commission, Food and Drug Administration, Department of Homeland Security, Department of Transportation, Department of Energy, and the Cybersecurity and Infrastructure Security Agency. Thirty-six states have enacted cyber security legislation, and the count increases as other countries join.

One of the motivating factors for all these new regulations is that most cyber attacks aren’t reported. Lawmakers realise cyber security threats continue to be one of the top national security and economic risks. In the last year and a half (2020-2022), there have been attacks on America’s gas supply, meat supply, and various other companies, courts, and government agencies. One FBI cyber security official estimated the government only learns about 20% to 25% of intrusions at US business and academic institutions.

In March, Congress passed legislation requiring critical infrastructure operators to report significant cyber attacks to CISA within 72 hours of learning about the attack. It also required them to report a ransomware payment within 24 hours. These regulations will also consider reporting “near misses” so that this data can also be studied and tracked. The problem is, how does one define a “near miss”?

  • This Year’s Biggest Cyber Threats

OpenText announced the Nastiest Malware of 2022, a ranking of the year’s biggest cyber threats. For the fifth year running, experts combed through the data, analysed different behaviours, and determined which malicious payloads are the nastiest.

Emotet regained its place at the top, reminding the world that while affiliates may be taken down, the masterminds are resilient. LockBit evolved its tactics into something never seen before: triple extortion. Analysis also revealed an almost 1100% increase in phishing during the first four months of 2022 compared to the same period in 2021, indicating a possible end to the “hacker holiday,” a hacker rest period following the busy holiday season.

“The key takeaway from this year’s findings is that malware remains centre stage in the threats posed towards individuals, businesses, and governments,” said OpenText.

“Cyber criminals continue to evolve their tactics, leaving the infosec community in a constant state of catch-up. With the mainstream adoption of ransomware payloads and cryptocurrency facilitating payments, the battle will continue. No person, no business—regardless of size—is immune to these threats.”

While this year’s list may designate payloads into different categories of malware, it’s important to note many of these bad actor groups contract work from others. This allows each group to specialise in their respective payload and perfect it.
