Black Arrow Cyber Threat Briefing 03 November 2023

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.

Surviving a Ransomware Attack Begins by Acknowledging it’s Inevitable

The best defence against a ransomware attack is assuming it will happen before it does.  Research by Visa Inc found that ransomware continues to rapidly rise. One of the main factors is the use of AI services to mass produce highly personalised and plausible emails. The second is the proliferation of highly professional do-it-yourself ransomware kits, which frequently come with 24/7 tech support. These two factors drastically lower the skill level required for cyber criminals to successfully pull off an attack.

Another new ransomware trend is “dual ransomware attacks”. This is where criminals carry out two or more attacks in close proximity of each other, ranging between 48 hours to a maximum of 10 days. With an 80% chance of re-attack, small and medium sized businesses in hard-hit industries including healthcare and manufacturing are primary targets; organisations must be extra vigilant as the holidays approach because this is when cyber criminals are most likely to attack.

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.

Are You and Your Clients Soft Targets?

Cyber attacks are not a matter of "if" but "when," and the question you need to ask yourself is, ‘Are you a soft target?’. A soft target is a network or organisation that is relatively unprotected or vulnerable to cyber attacks.

You may feel confident in your ability to recover from an attack, but if you've never thoroughly tested your backup and recovery procedures, and when the time comes you find that it does not work, the result will leave you more likely to pay a ransom in an encryption based ransomware scenario. Reliance on legacy antivirus, which often fails to detect modern threats, can also render your network a soft target. Additionally, the absence of a rigorous vulnerability scanning and patching process leaves vulnerabilities undiscovered, and attackers are quick to exploit them. If you rely solely on prevention measures like firewalls and endpoint protection platforms, you are making yourself an appealing soft target for cyber criminals.

No organisation is entirely immune to cyber attacks. The key to defending you and your client's information effectively is to anticipate attacks, understand your security posture, recognise potential adversaries, and recover correctly in the event of an attack.

Cyber Attacks Cause Revenue Losses in 42% of Small Businesses

Small businesses may be discouraged from investing in preventive cyber security measures due to the expense involved and the mistaken belief that only larger companies are the target of cyber crimes. However, according to a recent report nearly 8 in 10 small business leaders admit they are anxious about the safety of their company’s sensitive data and information. The report found that employee and customer data continue to be the most impacted categories of information in data breaches with 42% of small businesses losing revenue due to a cyber event.

The widespread use of internet-connected devices has given rise to a substantial surge in threat actors targeting small and medium-sized businesses, with malware, phishing and botnets being the most common threats. Daily malware activity has doubled year over year, and peaks in holiday seasons.

Executives May be The Biggest Risk to Your Business as One in Five Share Work Passwords Outside the Company

According to a recent report, nearly half (49%) of C-level executives have requested to bypass one or more security measures in the past year, highlighting a concerning disparity between what business leaders say about cyber and what they do. The research reported one in five sharing their work password with someone outside the company, 77% using easy-to-remember passwords including birth dates, and a third admitting to accessing unauthorised files and data with nearly two-thirds having the ability to edit those files/data.

Additionally, the C-suite was found to be more than three times as likely than regular users to share work devices with unauthorised users. An essential approach to reducing the risks is a tailored training programme that enables all users, including the C-suite, to understand the objective of security controls and the risks caused by bypassing them. Black Arrow offers bespoke training to all roles within the organisation as well as upskilling tailored to those at the board level.

Organisations Can Only Stop 57 Percent of Cyber Attacks

According to a report from Tenable, over the last two years, the average organisation's cyber security program was prepared to preventatively defend against, or block, just 57 percent of the cyber attacks it encountered. The report found that 58% of respondents focus almost entirely on fighting successful attacks rather than working to prevent them in the first place. This is put down largely to a struggle to obtain an accurate picture of their attack surface. When it came to risks, 75% viewed cloud infrastructure as the greatest source of exposure risk in their organisation.

Many Businesses Remain Unprepared for AI as Phishing Attacks Rise 1,265% Since Launch of ChatGPT

Generative AI has revolutionised many aspects of life, offering new opportunities that have also greatly benefited malicious actors. A report has found that since the launch of ChatGPT, phishing attacks have increased by 1,265%. A separate report found that many businesses remain unprepared for the impact of AI, with just 16% of respondents satisfied in their organisation’s understanding of these AI tools.

Business Email Compromise is Most Common Entry Point for Cyber Attack

According to cyber insurance provider Hiscox, almost half of UK businesses have experienced a cyber attack in the last year, an increase of 9% from the previous year. Business email compromise was recorded as the most common point of entry, mentioned by 35% of companies who suffered an attack.

The report found that 20% of attacked organisations received a ransomware demand, slightly up from 19% the previous year. The proportion paying the ransom fell from 66% to 63%, but the median ransom rose 13%.

US Regulator Charges Firm and its CISO For Fraud and Cyber Security Failures

The US Securities and Exchange Commission (SEC) announced plans to charge a Chief Information Security Officer (CISO) with fraud for their role in allegedly lying to investors, overstating cyber security practices, and understating or failing to disclose known risks. A key piece of evidence presented by the SEC involved a presentation that was shared with the CISO, detailing a lack of security in the CISO employer’s setup. The presentation highlighted how exploitation could lead to major reputational and financial loss.

The case represents a larger shift in the dynamics and corporate reporting of security issues and within this, lies the professionalism of the CISO role. It is likely that this incident could become the start of something larger.

Companies Scramble to Integrate Immediate Recovery into Ransomware Plans

A survey found that 66% of companies are reevaluating their data protection and cyber resilience strategies. Despite this, 35% are not prioritising recovery and only half (56.6%) focused on both recovery and prevention.

Whilst it is important to prevent attacks, nothing is 100% secure and organisations need to ensure that their ransomware plans include recovery as a part of this. If, or when, you experience an attack, you will not want to improvise your recovery.

Your End-Users are Reusing Passwords: That’s a Big Problem

Password reuse is a difficult vulnerability for IT teams to get full visibility over. The danger is often hidden until it turns up in the form of hackers using compromised credentials as an initial access vector. A recent survey revealed that 53% of people admit to reusing passwords, making it easier for attackers to gain access to multiple applications with a single compromised password.

While it is difficult for organisations to maintain visibility over who is reusing passwords, especially if employees are reusing passwords outside of the organisation, there are still ways to combat this. Implementing tools that can check for compromised passwords, using multi-factor authentication and ensuring all employees carry out cyber security and awareness training are a few methods to help combat password re-use.

Cyber Workforce Demand is Outpacing Supply

A study by ISC2 stated that we would need to double the cyber workforce to adequately protect organisations and their critical assets. The study found that the gap between the demand and supply grew 12.6%. For organisations, this can mean a struggle in hiring cyber expertise.

To address the challenge of attracting and retaining quality senior security professionals, Black Arrow offers a fractional CISO service that gives flexible access to a whole team of specialists with wide expertise, experience and backgrounds in technology, governance and transformation, for less than the cost of hiring one individual.

What the Boardroom Is Missing: CISOs

According to a new study only 12% of S&P 500 companies have board directors with relevant cyber credentials, highlighting a major gap in expertise needed to keep organisations secure. As most organisations shift to digital and cloud-first strategies, businesses of all shapes and sizes must protect their assets. Unfortunately, there's a considerable gap between security leaders and the board directors responsible for managing businesses. A recent Harvard Business Review survey revealed just 47% regularly interact with their company's Chief Information Security Officer (CISO). That's a severe knowledge gap for a company's security and business leaders.

Introducing CISOs to the boardroom is not just about compliance, it's also about ensuring transparency and accountability. CISOs are already building security programs from the ground up. They provide business compliance, hire the right people, and find the right technology to supplement their team's efforts. Security posture is critical to an enterprise's future success, and having a CISO on the board that speaks the language can help a board understand if their business is making suitable security investments.
