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
Boardroom Woes on Ransomware Intensify as Organisations Face an Average of 86 Ransomware-linked Events Annually
A recent report by Akamai Technologies has found that organisations experienced an average of 86 ransomware-linked events in the past 12 months (successful or not), double the number of annual attacks from 2 years ago.
The most common issues impacting organisations after a ransomware attack were network downtime (44%), data loss (42%) and brand/reputation damage (39%).
Ransomware attackers have increasingly employed tactics like double and triple extortion. These methods combine encryption, data exfiltration, and distributed denial of service (DDoS) attacks to extort money. While these strategies are not new, their prevalence has significantly increased in recent times.
With 81% of companies experiencing ransomware attacks in the previous 12 months this is increasingly something that company Boards are concerned about, not only the organisation’s ability to stop a ransomware attack in the first place, but also the organisation’s ability to recover when an attack happens.

Many SMBs Have No Real Way to Deal with Cyber Threats, Leaving Them Vulnerable
A recent report found that of nearly 6,000 small and medium-sized business (SMB) IT professionals surveyed across Europe, a third of those based in the UK have no cyber security in place to protect assets such as their own printers, with 16% suffering a printer breach alone in the past. Despite this, less than a quarter educated their employees about printer (23%) IT security. With hybrid working seen as a security concern for 38% of SMEs, and potentially leading to more remote use of these devices, surprisingly just 4 in 10 (41%) cover hybrid working as part of their current security training.
Black Arrow supports organisations of all sizes in designing and delivering proportionate user education and awareness programmes, including in-person and online training as well as simulated phishing campaigns. Our programmes help secure employee engagement and build a cyber security culture to protect the organisation.

Cyber Attacks Top Global Risk – 2023 Aon Survey
Aon’s Global Risk Management Survey identified cyber attacks and data breaches as the leading business risk worldwide, followed by business interruption. Aon warned that deficits in talent or specialised skills may exacerbate cyber risks in particular.
Supply chain disruptions were ranked as another area of concern, with risks associated with supply chain failure hitting a 14-year high in the survey. However, less than 40% of organisations have conducted supplier resilience assessments. which contributes to cyber risk when organisations hand data to suppliers without considering whether their suppliers keep that data safe.

To Improve Cyber Defences, Practice for Disaster
If you aren’t already running incident simulations in your organisation, it’s time to start. Such simulations allow employees to understand their roles and responsibilities, as well as providing a great opportunity to educate. Cyber attacks are a matter of when, not if, and no-one wants to be improvising their security response in the event of a real cyber incident.
Black Arrow works with organisations of all sizes and sectors to design and prepare for managing a cyber security incident; this can include an Incident Response Plan and an educational tabletop exercise for the leadership team that highlights the proportionate controls to help the organisation prevent and mitigate an incident.

Meet Your New Cyber Security Auditor: Your Insurer
In the dynamic world of cyber security, cyber insurers are emerging as key players, reshaping the landscape with ever more stringent requirements. With ransomware attacks becoming more complex, cyber insurance premiums have surged by 50%, challenging Chief Information Security Officers (CISOs) to demonstrate their organisation's cyber defence capabilities. Insurers, using detailed risk assessments, are influencing cyber security strategies, compelling organisations to adapt and meet higher standards.
CISOs are now tasked with ensuring their security measures are comprehensive and transparent, as insurers scrutinise everything from multifactor authentication to Active Directory policies. Accurate self-assessment is critical, as any misrepresentation can lead to denied coverage or legal repercussions. In this competitive market, organisations must showcase their cyber maturity, particularly in high-risk industries, to secure coverage. The evolving cyber insurance landscape demands a clear understanding of risk factors and continuous improvement in cyber defence strategies, ultimately aiming to enhance overall protection against cyber threats.

Allen and Overy Suffer Ransomware Attack
Allen & Overy, the “magic circle” law firm, has suffered a cyber attack on its systems, making it the latest large corporation to fall victim to a ransomware hack. A&O confirmed the incident after the infamous ransomware gang LockBit posted on social media platform X, formerly Twitter, claiming to have breached the legal giant and threatening to publish data from the firm’s files on 28 November.
Earlier this year, the UK National Cyber Security Centre reported that law firms of all sizes were at risk from cyber attackers because of the sensitive client information they routinely handle. The importance of reputation to the business also made law firms attractive targets for extortion.

Shadow IT Remains a Top Threat, as Shown by Attack on Okta
Shadow IT refers to IT resources used by employees or end users that don’t have IT approval or oversight. This was the case in the recent Okta attack in which an Okta employee signed into their personal Google account on a company-owned device. It is believed that the employee’s personal Google account had been compromised, and unfortunately since the employee had configured it in a way to save credentials of Okta accounts, the attacker now also had these credentials. The result? 134 downstream customers impacted.

Ransomware, AI, and Social Engineering All Set to Be 2024's Biggest Security Threats
Ransomware attacks surged to record highs in 2023 and are expected to escalate further, especially with key 2024 elections approaching, ZeroFox Intelligence's 2024 Key Forecasts report indicates. This trend is driven by evolving cyber threats, including sophisticated social engineering and AI-generated synthetic media, aimed at spreading misinformation and targeting electoral processes.
ZeroFox also highlights a concerning shift towards physical damages from cyber attacks, with critical sectors like finance, energy, and healthcare being vulnerable due to outdated security infrastructures. These sectors are likely targets for nation-state and state-sponsored attacks amidst global geopolitical tensions. To counter these threats, the report suggests enhanced security measures, including encrypted cloud backups, vigilant network monitoring, and a zero-trust cyber security approach to safeguard against the evolving landscape of cyber threats.

Cyber Governance: Growing Expectations for Information Security Oversight and Accountability
In today's interconnected digital economy, cyber security is a critical governance issue for businesses, necessitating effective oversight and strategic planning. The SEC's new rules, effective July 2023, require public companies to transparently disclose their cyber security strategies and report significant incidents, highlighting the increasing importance of cyber security in corporate governance. This regulatory development aims to improve transparency and accountability in managing cyber risks.
Corporations are responding by emphasising detailed cyber security disclosures, employee training programmes, and board-level expertise in information security. As the landscape of cyber threats evolves, timely and comprehensive reporting of breaches becomes more crucial, aligning with both regulatory requirements and stakeholder expectations for robust cyber security governance.
Black Arrow supports business leaders in organisations of all sizes to demonstrate governance of their cyber security by owning their cyber security strategy and leveraging their existing internal and external resources to build resilience against a cyber security incident.

Generative AI Will Level Up Cyber Attacks, According to New Google Report
Google's Cloud Cyber Security Forecast 2024 report reveals a growing trend of using generative AI in cyber attacks. The technology, particularly large language models (LLMs), is enhancing phishing and social engineering tactics by producing content that appears more legitimate, making it difficult to spot errors typically associated with such attacks. This advancement allows attackers to mimic natural language effectively and create authentic-looking fake news, phone calls, and deepfake videos, potentially eroding public trust in online information.
On the flip side, the report highlights the potential of AI as a powerful tool for cyber defence. Cyber security professionals can leverage AI for rapid data synthesis, efficient threat detection, and swift response actions. As defenders direct AI development with specific security objectives, its capabilities are expected to significantly bolster cyber security measures in the near future.

Public Wi-Fi Remains a Huge Risk, is Your Organisation Prepared?
New research found that half of UK participants believed they are most at risk of a cyber attack when using public Wi-Fi, which is Wi-Fi that anyone, including an attacker, can connect to. However, in contrast to concerns, the report found that 41% will use unsecured Wi-Fi if given the opportunity. Further, 53% of participants would enter or access sensitive information whilst connected to an unsecured public Wi-Fi network; this includes bring your own devices (BYOD) that have access to corporate data.

88% of Security Leaders Think Their Organisation Is Falling Short in Addressing Cyber Security
A recent study by Foundry reveals a trend towards AI-driven security measures and increased reliance on cyber insurance among organisations. Key priorities for security leaders include preparedness for incidents, data protection, and enhancing IT and cloud data security. Despite this, 88% of security leaders feel their organisations are inadequate in addressing cyber security risks, mainly due to budget limitations, talent scarcity, and challenges in stakeholder communication.
To improve the situation, more top security executives are having regular engagements with the board of directors (85% this year compared to 82% in 2022), aiding in better cyber security initiatives. Security budgets are expected to remain stable or increase, with investments focused on authentication, data analytics, and cloud security, complemented by cyber insurance. AI's role is expanding in threat detection, malware identification, and automated responses, showcasing its growing importance in evolving security landscapes.

Top Cyber Stories of the Last Week
Cyber Criminals Shifting Focus: IT Sector Most Targeted In 2021
Darktrace reported that the IT and communications sector was globally the most targeted industry by cybercriminals in 2021.
Darktrace’s data is developed by ‘early indicator analysis’ that looks at the breadcrumbs of potential cyber-attacks at several stages before they are attributed to any particular actor and before they escalate into a full-blown crisis. Findings show that its artificial intelligence autonomously interrupted an average of 150,000 threats per week against the sector in 2021.
The IT and communications sector includes telecommunications providers, software developers, and managed security service providers, amongst others. There was also a growing trend of hackers targeting backup servers in an attempt to deliberately disable or corrupt backup files by deleting a single index file that would render all backups inaccessible. Attackers could then launch ransomware attacks against the clients of the backup vendor, preventing recovery and forcing payment.
In 2020, the most attacked industry was the financial and insurance sector, showing that cyber-criminals have shifted their focus over the last 12 months.
Over the last 12 months, it is clear that attackers are relentlessly trying to access the networks of trusted suppliers in the IT and communications sector. Quite simply, it is a better return on investment than, for example, going after one company in the financial services sector. SolarWinds and Kaseya are just two well-known and recent examples of this. Sadly, there is likely to be more in the near term.
The findings of this research mark one year since the compromise of US software company SolarWinds rattled the security industry. This landmark supply-chain attack made thousands of organisations vulnerable to infiltration by inserting malicious code into the Orion system. Over the last 12 months, there has been a continued spate of attacks against the IT and communications sector, including the high-profile attacks on Kaseya and Gitlab.

New Ransomware Variants Flourish Amid Law Enforcement Actions
Ransomware groups continue to evolve their tactics and techniques to deploy file-encrypting malware on compromised systems, notwithstanding law enforcement's disruptive actions against the cyber crime gangs to prevent them from victimizing additional companies.
"Be it due to law enforcement, infighting amongst groups or people abandoning variants altogether, the RaaS [ransomware-as-a-service] groups dominating the ecosystem at this point in time are completely different than just a few months ago," Intel 471 researchers said in a report published this month. "Yet, even with the shift in the variants, ransomware incidents as a whole are still on the rise."
Sweeping law enforcement operations undertaken by government agencies in recent months have brought about rapid shifts in the RaaS landscape and turned the tables on ransomware syndicates like Avaddon, BlackMatter, Cl0p, DarkSide, Egregor, and REvil, forcing the actors to slow down or shut down their businesses altogether.
https://thehackernews.com/2021/12/new-ransomware-variants-flourish-amid.html
93% of Tested Networks Vulnerable to Breach, Pen Testers Find
Data from dozens of penetration tests and security assessments suggest nearly every organisation can be infiltrated by cyber attackers.
The vast majority of businesses can be compromised within a month by a motivated attacker using common techniques, such as compromising credential, exploiting known vulnerabilities in software and Web applications, or taking advantage of configuration flaws, according to an analysis of security assessments by Positive Technologies.
In 93% of cases, an external attacker could breach a target company's network and gain access to local devices and systems, the company's security service professionals found. In 71% of cases, the attacker could affect the businesses in a way deemed "unacceptable." For example, every bank tested by the security firm could be attacked in a way that disrupted business processes and reduced the quality of their service.
Dridex Malware Trolls Employees With Fake Job Termination Emails
A new Dridex malware phishing campaign is using fake employee termination emails as a lure to open a malicious Excel document, which then trolls the victim with a season's greeting message.
Dridex is a banking malware spread through malicious emails that was initially developed to steal online banking credentials. Over time, the developers evolved the malware to use different modules that provide additional malicious behaviour, such as installing other malware payloads, providing remote access to threat actors, or spreading to other devices on the network.
This malware was created by a hacking group known as Evil Corp, which is behind various ransomware operations, such as BitPaymer, DoppelPaymer, WastedLocker variants, and Grief. Due to this, Dridex infections are known to lead to ransomware attacks on compromised networks.
More Than 35,000 Java Packages Impacted By Log4j Flaw, Google Warns
The Google Open Source Team scanned the Maven Central Java package repository and found that 35,863 packages (8% of the total) were using versions of the Apache Log4j library vulnerable to Log4Shell exploit and to the CVE-2021-45046 RCE.
“More than 35,000 Java packages, amounting to over 8% of the Maven Central repository (the most significant Java package repository), have been impacted by the recently disclosed log4j vulnerabilities (1, 2), with widespread fallout across the software industry.” reads the report published by Google. “As far as ecosystem impact goes, 8% is enormous.”
The Google experts used the Open Source Insights, a project used to determine open source dependencies, to assess all versions of all artifacts in the Maven Central Repository.
The experts pointed out that the direct dependencies account for around 7,000 of the affected packages. Most of the affected artifacts are related to indirect dependencies.
Since the vulnerability was disclosed, 13% of all vulnerable packages have been fixed (4,620).

A new informational Log4J advisory has been issued by cybersecurity leaders from the US, Australia, Canada, New Zealand and the United Kingdom. The guide includes technical details, mitigations and resources to address known vulnerabilities in the Apache Log4j software library.
The project is a joint effort by the US' Cybersecurity and Infrastructure Security Agency (CISA), FBI and NSA, as well as the Australian Cyber Security Centre (ACSC), Canadian Centre for Cyber Security (CCCS), Computer Emergency Response Team New Zealand (CERT NZ), New Zealand National Cyber Secure Centre (NZ NCSC), and the United Kingdom's National Cyber Security Centre (NCSC-UK).
The organisations said they issued the advisory in response to "active, worldwide exploitation by numerous threat actors, including malicious cyber threat actors." Numerous groups from North Korea, Iran, Turkey and China have been seen exploiting the vulnerability alongside a slate of ransomware groups and cybercriminal organisations.
Conti Ransomware Gang Has Full Log4Shell Attack Chain
The Conti gang was the first professional-grade, sophisticated ransomware group to weaponise Log4j2, now with a full attack chain.
The Conti ransomware gang, which last week became the first professional crimeware outfit to adopt and weaponize the Log4Shell vulnerability, has now built up a holistic attack chain.
The sophisticated Russia-based Conti group – which Palo Alto Networks has called “one of the most ruthless” of dozens of ransomware groups currently known to be active – was in the right place at the right time with the right tools when Log4Shell hit the scene 10 days ago, security firm Advanced Intelligence (AdvIntel) said in a report shared with Threatpost on Thursday.
As of Monday the attack chain has taken the following form, AdvIntel’s Yelisey Boguslavskiy told Threatpost: Emotet -> Cobalt Strike -> Human Exploitation -> (no ADMIN$ share) -> Kerberoast -> vCenter ESXi with log4shell scan for vCenter.

Second Ransomware Family Exploiting Log4j Spotted In US, Europe
This was quickly followed by a second ransomware group when researchers found a second family of ransomware has been growing in usage for attack attempts that exploit the critical vulnerability in Apache Log4j, including in the US and Europe.
A number of researchers, including at cybersecurity giant Sophos, have now said they’ve observed the attempted deployment of a ransomware family known as TellYouThePass. Researchers have described TellYouThePass as an older and largely inactive ransomware family — which has been revived following the discovery of the vulnerability in the widely used Log4j logging software.

Threat actors steal $80 million per month with fake giveaways, surveys
Scammers are estimated to have made $80 million per month by impersonating popular brands asking people to participate in fake surveys or giveaways.
Researchers warn of this new trend in global fraud schemes involving targeted links to make investigation and take-down increasingly challenging.
According to current estimates, these massive campaigns resulted in an estimated $80,000,000 per month, stolen from 10 million people in 91 countries.
The scam themes are the typical and "trustworthy" fake surveys and giveaways from popular brands with the holiday season making targets more susceptible to fraudulent gift offerings.
According to a report by Group-IB, there are currently 60 known scam networks that use targeted links in their campaigns, impersonating 121 brands in false giveaways.
Each network uses an average of 70 different Internet domain names as part of their campaigns, but some find great success with fewer domains, which indicates that quality beats quantity when it comes to scams.
Microsoft Teams might have a few serious security issues
Security researchers have discovered four separate vulnerabilities in Microsoft Teams that could be exploited by an attacker to spoof link previews, leak IP addresses and even access the software giant's internal services.
These discoveries were made by researchers at Positive Security who “stumbled upon” them while looking for a way to bypass the Same-Origin Policy (SOP) in Teams and Electron according to a new blog post. For those unfamiliar, SOP is a security mechanism found in browsers that helps stop websites from attacking one another.
During their investigation into the matter, the researchers found that they could bypass the SOP in Teams by abusing the link preview feature in Microsoft's video conferencing software by allowing the client to generate a link preview for the target page and then using either summary text or optical character recognition (OCR) on the preview image to extract information.

The Future of Work Has Changed, and Your Security Mindset Needs to Follow
VPNs have become a vulnerability that puts organisations at risk of cyber attacks.
When businesses first sent employees to work from home in March 2020 — thinking it'd only be for two weeks — they turned to quick fixes that would enable remote work for large numbers of people as quickly as possible. While these solutions solved the short-term challenge of allowing distributed workforces to connect to a company's network from anywhere, they're now becoming a security vulnerability that is putting organisations at risk of growing cyberattacks.
Now that almost two years have passed and work has fundamentally shifted, with fully or hybrid remote environments here to stay, business and security leaders need solutions that better fit their unique and increasingly complex needs. In fact, a new survey from Menlo Security has found that 75% of organisations are re-evaluating their security strategies for remote employees, exemplifying that accommodating remote work is a top priority for the majority of business leaders.
To successfully manage the risks that distributed workforces entail, leaders must shift their mindset away from the hub-and-spoke approach of providing connectivity to the entire network, instead segmenting access by each individual private application, wherever it is deployed, as threats of cyberattacks loom across all industries. As organisations grapple with the added security challenges that remote and hybrid work environments bring, adopting a zero-trust approach will be critical for end-to-end network and endpoint protection.
