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

Majority of 2023’s Critical Cyber Attacks Stemmed from Fewer Than 1% of Vulnerabilities, with 1 in 4 High Risk Vulnerabilities Exploited Within 24 Hours of Going Public

A new Qualys report reveals that less than 1% of vulnerabilities are responsible for the greatest damage, and a quarter of high-risk vulnerabilities are now being exploited within a day of disclosure. In 2023, a record-breaking 26,000 vulnerabilities have been identified so far, emphasising the need for organisations to accelerate their response times. High-risk vulnerabilities, particularly in network devices and web applications, are the main targets for attackers seeking unauthorised access or privilege escalation. This situation underscores the critical need for organisations to implement a multi-layered defence strategy, automate patching where appropriate especially in areas of critical infrastructure, and adopt zero-trust principles to safeguard against such swift and potent cyber threats.

Ransomware Gangs Are Increasingly Turning to Remote Access Tools for Attacks, As UK Honeypots Attacked 17 million Times Per Day

Nearly three quarters of cyber-attacks across the UK in 2023 targeted technology frequently used for remote working, new data from Coalition has revealed.

Attackers frequently target Remote Desktop Protocol (RDP), a tool that lets users access office computers from home, as it grants the attacker quick access to devices and allows them to execute further attacks.

Honeypot sensors maintained by Coalition have recorded 5.8 billion attacks so far in 2023, averaging around 17 million attacks per day. Of these it was found that 76% of attacks targeted RDP.

Attackers exploit RDP vulnerabilities that often stem from simple configuration mistakes. By taking steps like disabling unnecessary remote access or tightening controls, companies can help shield themselves from these pervasive threats.

Why Employees Are a Bigger Security Risk than Hackers

In today's interconnected world, the spotlight is often on cyber criminals attacking from outside, but a worrying trend points inward. A recent study by Imperva reveals that insiders pose a significant threat, being behind 58% of security incidents. The incidents are a mixture of deliberate misuse and accidents, however the majority of organisations lack a strategy to combat these risks. Even when strategies exist, they may be undermined by employees bypassing IT protocols or due to the pressures of adapting to new technologies. With insider incidents on the rise by 47% in two years, the costs are too great to ignore.

77% of Financial Services Firms Detected a Cyber Attack in the Last Year, as Finance and Healthcare Continue to Suffer the Most Cyber Attacks

Cyber attacks are more prevalent in the financial services sector than in any other industry. Last year, 77% of financial institutions were targeted, primarily through phishing and ransomware attacks. After financial services the second most targeted sector is healthcare. Both types of institutions are attractive targets not only because of their wealth of sensitive data but also because disruptions to their operations can lead to substantial ransom payments. They face increasingly sophisticated threats and the financial impact is significant, with approximately a quarter of these institutions estimating damages of at least $50,000. To mitigate these risks organisations are turning to cyber insurance, which necessitates further tightening of security practices, including identity and access management, to meet insurers’ stringent standards.

The healthcare sector reported over 179,000 cyber attacks in a single quarter, affecting entities globally. The primary threats were infostealers and ransomware. There have been scores of notable incidents where hospitals have been shut down or otherwise unable to operate. In many cases, this resulted in closing emergency departments, interfering with planned or emergency surgeries and forcing ambulances to divert to other hospitals, potentially causing life threatening delays. Further, a recent report analysing the enterprise risk management for the financial sector found that the two biggest concerns were rising interest rates at 74% and ransomware attacks at 65%.

New Report Data Shows 75% Increase in Suspicious Emails Hitting Inboxes

A new report has unveiled the escalating threat posed by phishing emails, as detected by DMARC software. In the past year, there's been a 70% rise in emails flagged as fraudulent, with almost 18% of total email traffic in the first half of 2023 being intercepted as potential phishing attempts. This surge underscores a pressing need for robust email security measures. Simple yet effective tools like DMARC, which automatically weeds out emails impersonating legitimate domains, are becoming critical in the fight against these sophisticated scams. With the average cost of a cyber attack now well into the millions, and given the high click rates on phishing emails, it is clear that taking proactive steps to strengthen an organisations digital defence is not just sensible, it is essential for safeguarding the businesses in the digital age.

Threat Actors Still Exploiting Old Unpatched Vulnerabilities

A report by Cisco has found that the most targeted vulnerabilities this year, same as previous years, were old unpatched vulnerabilities which should have been fixed a long time ago. Some of these security gaps in widely-used applications like Microsoft Office and or within versions of Windows itself are over a decade old. Unpatched vulnerabilities can leave systems open to exploitation, potentially leading to unauthorised access, data breaches, and widespread security incidents, including being a key enabler of ransomware attacks. This highlights an urgent call to action for organisations to patch known vulnerabilities and secure user accounts to fortify their defences against cyber threats.

Many Organisations Still Lack Formal Cyber Security Training

As we navigate into 2024, a new report by the SANS Institute found that more than 30% of organisations do not regularly perform cyber readiness exercises, while 40% have yet to establish formal training for cyber security. These findings underline a gap between the need for robust security measures and actual preparedness. On a positive note, most organisations are adopting frameworks like the NIST CSF to shape their security posture, and two-thirds are actively using metrics to gauge the effectiveness of their security operations. Yet, there’s a call to action here: for real progress, intentional investment and commitment to comprehensive training and stringent security operations are non-negotiable. This is the path to mature security operations that can withstand the complexities of today’s cyber threats.

Addressing the Growing Threat of Supply Chain Cyber Attacks

As businesses become more interconnected through digital supply chains, supply chain cyber attacks are becoming more of a pressing issue for organisations. The attackers tend to exploit weaknesses in third-party suppliers, often with less guarded entry points, to access larger networks. With companies increasingly outsourcing and using cloud adoption, the need for stringent third-party cyber risk assessments is vital. However, complexities arise with the shared responsibility model for cloud security, where setting out the division of security duties between cloud service providers and clients can blur lines of defence. To tackle these challenges, integration of cyber security into procurement and supply chain processes is essential. This means enforcing collaboration between procurement and cyber security teams, mandating security standards in vendor contracts, and utilising automated tools for continuous risk assessments. Safeguarding modern supply chains is no longer a siloed task but a strategic, organisation wide imperative.

Cyber Incident Costs Surge 11% as Budgets Remain Muted

A new report found an 11% jump in the direct costs of a significant cyber incident, now averaging $1.7 million. The burden is even heavier for those without cyber insurance, with costs escalating to $2.7 million per incident. Cyber risks like fraud, third-party breaches, and data theft remain prevalent. Despite these increasing threats, cyber security budgets have grown modestly and are not keeping pace with the increased level of threat. The report also highlights a concerning gap in understanding cyber threats and a lack of internal training, emphasising the critical need for not just financial investment, but also a deeper engagement with cyber security training and awareness within organisations.

Attacks on Critical Infrastructure are Harbingers of War: Are We Prepared?

The escalating cyber threats against critical infrastructure, like recent attacks on water authorities, highlight an urgent security concern. These attacks, which are often state-sponsored, are not just targeting financial or data assets but are striking at essential services vital to human survival. The tactics used in these attacks, known as Intelligence Preparation of the Battlefield (IPB), are aimed at weakening a nation by disrupting services like power and water, key to both civil stability and military operations. Nations like Russia, China, and Iran employ these strategies for different purposes, ranging from strategic military advantages to ideological victories. The use of ransomware, as seen in the increasing incidents reported by the FBI, is a tool for both financial gain and geopolitical disruption. As we face these multifaceted threats, the need for robust cyber security measures to protect our critical infrastructure has never been more pressing. It is a call to action for nations and organisations alike to fortify their defences against these evolving and serious cyber threats.

UK Data Centres to be Classed as Critical Infrastructure Under New Gov Proposals

The UK government is considering new regulations aimed at enhancing the security and resilience of data centres. The Department for Science, Innovation and Technology (DSIT) recognises the vital role of these data hubs and is examining the adequacy of current safety practices. With the identification of varying levels of security across the sector, the prospect of legislating minimum security standards is on the table. This may include establishing a regulatory body to oversee incident reporting and risk mitigation strategies, particularly for third-party service providers. These measures underscore the government's commitment to safeguarding data centres, which are increasingly integral to the UK's economic vitality and national security. As part of a broader initiative, the sector could be designated as critical national infrastructure, aligning it with international best practices and ensuring comprehensive protection from cyber threats and other risks.

Data Exfiltration and Extortion is the New Ransomware Threat, as 65% of Organisations Say Ransomware Concerns Impact Risk Management

Cyber criminals are escalating their tactics and becoming more aggressive in their effort to maximise disruption and compel the payment of ransom demands. Earlier this year, the ransomware group ALPHV exploited the new US data breach disclosure rules by filing a complaint with the US Securities and Exchange Commission (SEC) against a victim company for not reporting an alleged significant data breach. This marks a strategic evolution from traditional ransomware attacks, where data is encrypted and held hostage, to more nuanced extortion schemes. Such tactics are becoming more sophisticated, with triple extortion attacks threatening not just the target company but also their partners and clients. This shift from encryption to pure extortion requires a fresh understanding of cyber threats and a re-evaluation of defence strategies. It highlights the urgent need for businesses to protect not just their own data but also to consider the security of their entire data supply chain.

Top Cyber Stories of the Last Week

New Strain Of Ransomware Implements Self-Spreading Capabilities

French experts spotted a new Ryuk ransomware variant that implements self-spreading capabilities to infect other devices on victims’ local networks.

This new version has a new attribute that allows it to self replicate over the local network allowing the malware to propagate itself – machine to machine – within the Windows domain. Once launched, it will spread itself to every Windows machine it can reach.

One In Four People Use Work Passwords For Consumer Websites

The report found that one in four consumers admit to using their work email or passwords to log in to consumer websites and applications such as food delivery apps, online shopping sites and even dating apps. The report found that consumers are neglecting to implement fundamental security safeguards across smart IoT devices at home, which could have serious security ramifications on both the individual and the enterprise amid increased and ongoing remote work spurred by the COVID-19 pandemic.

Massive Rise In Threats Across Expanding Attack Surfaces

New malware samples nearly doubled: New ransomware samples increased 106% year-over-year. Trojans increased 128%, with threat actors using trojans to exploit lower-severity vulnerabilities. Sophisticated, multi-staged attacks and malware-as-a-service have become the norm. Vulnerabilities hit a new high: 18,341 new vulnerabilities in 2020 have been reported. To stay ahead of attacks, security and risk leaders need sophisticated insights into which vulnerabilities are high-risk and remediation options for all assets, including non-patching options.

Is Your Browser Extension A Botnet Backdoor?

A company that rents out access to more than 10 million Web browsers so that clients can hide their true Internet addresses has built its network by paying browser extension makers to quietly include its code in their creations. This story examines the lopsided economics of extension development, and why installing an extension can be such a risky proposition.

Cyber Attack Shuts Down Online Learning At 15 UK Schools

A threat actor was able to access the trust's central network infrastructure and while an investigation took place, all existing phone, email, and website communication had to be pulled. Students are still learning remotely in England. Schools are set to reopen on March 8, but in the meantime, only a small subset of children are attending school physically, such as the children of key workers.

First Fully Weaponized Spectre Exploit Discovered Online

A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered and targets Spectre, a major vulnerability that was disclosed in January 2018. According to its website, the Spectre bug is a hardware design flaw in the architectures of Intel, AMD, and ARM processors that allows code running inside bad apps to break the isolation between different applications at the CPU level and then steal sensitive data from other apps running on the same system.

Solarwinds Security Fiasco May Have Started With Simple Password Blunders

We still do not know just how bad the SolarWinds security breach is. We do know over a hundred US government agencies and companies were cracked. "The largest and most sophisticated attack the world has ever seen," with more than a thousand hackers behind it. It may have all started when an intern first set an important password to "'solarwinds123." Then, adding insult to injury, the intern shared the password on GitHub.
