Top Cyber Stories of the Last Week

Top 12 Exploited Vulnerabilities List Highlights Troubling Reality That Many Organisations Are Still Not Patching

A joint advisory from US and allied cyber security agencies highlights the top routinely exploited vulnerabilities. This is a list that includes old and well-known bugs that many organisations still have not patched, including some vulnerabilities that have been known for more than five years. The list underscores how exploiting years-old vulnerabilities in unpatched systems continues to dominate the threat landscape. Organisations are more likely to be compromised by a bug found in 2021 or 2020 than they are by ones discovered over the past year.

This report emphasises that a vulnerability management strategy relying solely on CVSS for vulnerability prioritisation is proving to be insufficient at best; CVSS is an established method for assigning criticality scores to known vulnerabilities based on different scoring criteria. Additional context is required to allow for a more scalable and effective prioritisation strategy. This context should stem from internal sources, for example, the target environment (asset criticality, mitigating controls, reachability), as well as from external sources, which will permit a better assessment of the likelihood and feasibility of exploitation. Most organisations have a limited patching capacity, affected by the tooling, processes, and skills at their disposal. The challenge is to direct that limited patching capacity towards vulnerabilities that matter most in terms of risk reduction. Therefore, the task of sifting the signal through the noise is becoming increasingly more important.

67% of Data Breaches Start with a Single Click, with 1 in 100 Emails Being Malicious

In a report that leveraged data from 23.5 billion cyber security attacks, spanning 500 threat types and 900 distinct infrastructure and software vulnerabilities it was found that approximately 67% of all breaches start with someone clicking on a seemingly safe link, which explains why adversaries begin 80-95% of all attacks with a phishing email.

A separate report found that there was a 36% rise in cyber attacks in the first half of 2023. Email continued to be the main vector for delivering malicious content, with as many as 1 in every 100 emails sent in the first half of 2023 found to be malicious. In addition, malware accounted for 20% of attacks, and business email compromise (BEC) constituted 8%.

The findings reinforce the need for organisations to employ effective and regular security awareness training for users to better help them to not only identify, but also report such attacks to help strengthen the cyber resilience of the organisation. Black Arrow offers bespoke training to all roles within the organisation as well as upskilling tailored to those at the board level.

Ransomware Attacks Hit All Time High. Attackers’ Motives Change, So Should Your Defence

Cases of straight-up data theft and extortion now appear to be more widespread a threat than ransomware, becoming the single most observed threat in the second calendar quarter of 2023, according to new data released by researchers. 1,378 organisations have been named as victims on ransomware data-leak websites in Q2 2023. This was a 64.4% increase from the record-breaking number of victims named in Q1 2023.

Despite both the rise in threats and the high percentage of respondents whose organisations suffered recent attacks, there hasn’t been a corresponding uptick in strategic measures to shore up cyber resilience. In fact, close to four in five survey respondents don’t have complete confidence that their company has a cyber resilience strategy designed to address today’s escalating cyber challenges and threats.

The Generative AI War Between Companies and Hackers is Starting

To no one’s surprise, criminals are tapping open-source generative AI programs for all kinds of heinous acts, including developing malware and phishing attacks, according to the FBI. This comes as the UK National Risk Register officially classes AI as a long-term security threat. It’s safe to say AI is certainly a controversial field right now, with the battle between companies and hackers really starting to take place; only recently had technology giants such as Amazon, Google, Meta and Microsoft met with the US President Joe Biden to pledge to follow safeguards.

A recent report from security firm Barracuda has found that between August 2022 and July 2023, ransomware attacks had doubled and this surge has largely been driven by the breaching of networks via AI-crafted phishing campaigns, as well as automating attacks to increase reach, again using AI.

Despite the controversy, AI can be of tremendous value to organisations, helping to streamline and automate tasks. Organisations employing or looking to employ AI in the workplace should also have effective governance and identification procedures over the usage of said AI. Equally, when it comes to defending against AI attacks, organisations need to have a clear picture of their attack landscape, with layers of defence.

Spend to Save: The CFO’s Guide to Cyber Security Investment

As a CFO, you need to make smart choices about cyber security investments. The increasing impact of data breaches creates a paradox: While more spending is necessary to combat these challenges, this spending isn’t directly tied to profit. Instead, cyber security spending should be seen an investment in the future of your business.

The impact of a cyber event extends beyond quantifiable currency loss. Further impacts include those of reputation and customer retention. CFOs should look to identify weak spots, understand the effect these can have, pick the right solution that mitigates these and finally, advocate cyber security and robust governance at the board level.

It is important to remember, cyber security is not just a technical issue, but also a business one, and you have a key role in ensuring the security and resilience of your organisation.

Corporate Boards Take Heed: Give CISOs the Cold Shoulder at your Peril

The debate over whether the CISO should, by the very nature of the position, be considered a member of the C-suite has been raging for some time and seems likely to continue for a good while to come. CISOs should not only have a seat among the uppermost echelon at the big table but also be recognised as a foundational element in the success of any business.

There is a danger that, without an effective CISO, organisations can end up in a perilous situation in which there's no one driving the cyber security bus at a time when vulnerabilities and incidents are ever on the rise. When the CISO has a seat at the big table, everybody wins.

How the Talent Shortage Impacts Cyber Security Leadership

The lack of a skilled cyber security workforce hampers the effectiveness of an organisation’s security program. While technologies like AI and machine learning can provide some support, they are not sufficient, especially for small and medium sized businesses (SMBs). The cyber security workforce shortage affects not just current security but the future of leadership roles, including CISOs and CSOs.

Today’s CISOs require a blend of technology and business understanding. According to the (ISC)2 2022 Workforce Study, the global cyber security workforce is nearly 5 million and growing at 26% yearly. However, more than 3 million jobs still need to be filled, including specialised roles in cloud security, data protection, and incident response. This gap jeopardises functions like risk assessment, oversight, and systems patching.

The greatest talent shortage is found in soft skills, leading to a trend of looking outside the traditional security talent pool. The future of CISOs will likely require a solid security background, but as the talent gap widens, finding leadership candidates from the existing pool may remain challenging.

Salesforce, Meta Suffer Phishing Campaign that Evades Typical Detection Methods

A recent report by cyber security company identified a sophisticated email phishing campaign exploiting a zero-day vulnerability in Salesforce's legitimate email services. The vulnerability allowed threat actors to craft targeted phishing emails, cleverly evading conventional detection methods by leveraging Salesforce's domain and reputation and exploiting legacy quirks in Facebook's web games platform.

Whilst Facebook and Salesforce have now addressed the issue, it goes to show that technology alone is not enough to stop phishing; operational and people controls are still necessary and should form part of an effective organisational response.

Cyber Insurance and the Ransomware Challenge

The cyber insurance industry has been heavily criticised for providing coverage for ransom payments. A frequent accusation, which has become close to perceived wisdom in policymaking and cyber security discussions on ransomware, is that cyber insurance has incentivised victims to pay a ransom following a cyber incident, rather than seek alternative remediation options. However, the insurance industry could do much more to instil discipline in both insureds and the ransomware response ecosystem in relation to ransom payments to reduce cyber criminals’ profits. Insurers’ role as convenors of incident response services gives them considerable power to reward firms that drive best practices and only guide victims towards payment as a last resort.

While the insurance industry has the power to do this, there are still challenges that need to be addressed in the underwriting process. Offering expensive policies that exclude common risks such as ransomware or nation-state attacks is simply not a sustainable approach. This has helped insurers become more profitable for now, but these are only short-term fixes to the real problem at hand. Namely, that the underwriting process for cyber insurance policies is still not that sophisticated. Most underwriters are poorly equipped to effectively measure the cyber risk exposure of new or renewing customers.

Microsoft Exposes Russian Hackers' Sneaky Phishing Tactics via Microsoft Teams Chats

Microsoft on Wednesday disclosed that it identified a set of highly targeted social engineering attacks mounted by a Russian nation-state threat actor using credential theft phishing lures sent as Microsoft Teams chats. The tech giant attributed the attacks to a group it tracks as Midnight Blizzard.

"In this latest activity, the threat actor uses previously compromised Microsoft 365 tenants owned by small businesses to create new domains that appear as technical support entities" Microsoft said. "Using these domains from compromised tenants, Midnight Blizzard leverages Teams messages to send lures that attempt to steal credentials from a targeted organisation by engaging a user and eliciting approval of multi-factor authentication (MFA) prompts."

66% of Cyber security Leaders Don’t Trust Their Current Cyber Risk Mitigation Strategies

A recent report found that 66% of cyber security leaders don’t trust their current cyber risk mitigation strategies. It was also found that while 90% of respondents say their organisation has dedicated resources responsible for managing and reducing cyber risk, in almost half of situations (46%) this consists of just one person.

In some cases, it can be hard to get the necessary talent to build out the cyber security arm of an organisation; this is where organisations can look towards outsourcing to fulfil positions with expertise. At Black Arrow we offer many services to help you to govern your cyber security, including as virtual CISO that leverages our diverse team with backgrounds from British intelligence, board governance, IT and finance.

UK legal Sector at Risk, National Cyber Security Centre Warns

Over the past three years more than 200 ransomware attacks worldwide have been inflicted on companies in the legal industry. The UK was the second most-attacked country constituting 2.3% of all ransomware attacks across various sectors. The legal sector was the fourth most-attacked industry in the UK in 2022. Ransomware groups are indiscriminate in their targeting, attacking companies of all sizes, from small law firms with only ten employees to large firms with 1,000+ employees, and ranging in revenue from companies generating £100 million to those with under £3 million. No single kind of company is immune to these attacks.

The International Bar Association (IBA) has released a report to guide senior executives and boards in protecting their organisations from cyber risk. Entitled "Global perspectives on protecting against cyber risks: best governance practices for senior executives and boards of directors," the report aims to provide leaders with insight into the primary elements of a robust cyber risk management programme. Its recommendations for senior executives and boards encompass understanding the organisation's cyber risk profile, knowing what information assets to safeguard, being aware of significant regulatory requirements, and recognising the security standards utilised by the organisation.

Startups Should Move Fast and Remember Cyber Security

The importance of cyber security for startups, which can often be overlooked in the pursuit of fast-paced growth, cannot be overstated. However, cyber attacks can have devastating consequences for businesses of all sizes. The percentage of micro-businesses in the UK that consider cyber security a high priority has dropped from 80% to 68% in the past year, possibly due to wider economic pressures. Cyber criminals target businesses of all sizes, often initially using automated software to find weak spots. Startups can be particularly vulnerable due to their fast-paced environments and new or less familiar supply chains. The use of shared office spaces can also increase risk.

The UK DCMS/DSIT 2023 Cyber Security Breaches survey reported that almost a third of businesses (32%) and a quarter of charities (24%) reported breaches or attacks in the past 12 months alone, with the average victim losing £15,300. Startups have the unique advantage of being able to implement cyber security best practices from the outset and embed them into company culture. It is recommended that startups prioritise cyber security from the get-go to protect their business and ensure long-term growth.
