Black Arrow Cyber Threat Briefing 14 April 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.

Top Cyber Stories of the Last Week

  • Almost Half of Former Employees Say Their Passwords Still Work

An alarming number of organisations are not properly offboarding employees when they leave, especially in regard to passwords. In a new survey of 1,000 workers who had access to company passwords at their previous jobs, 47% admitted to using them after leaving the company.

According to the survey one in three respondents said they had been using the passwords for upwards of two years, which is a distressingly long time for organisations not to be aware of who is accessing those accounts and services.

When asked what they use the passwords for, 64% said to access their former email accounts and 44% to access company data. A concerning 10% of respondents said they were trying to disrupt company activities.

  • Efficient Risk Based Patch Management Means Eliminating Just 2% of Exposures Could Protect 90% of Critical Assets

A recent cyber security report analysed over 60 million security exposures, or weaknesses that could give an attacker access to systems. The report found that only 2% enabled attackers access to critical assets, while 75% of exposures along attack paths lead to “dead ends”. Further, the report shows that average organisations have 11,000 exploitable security exposures monthly, with techniques targeting credentials and permissions affecting 82% of organisations and exploits accounting for over 70% of all identified security exposures.

The report found that most security alerts were benign and did not lead to critical assets. By applying efficient risk based patch management and reducing unnecessary access to critical assets, organisations can mitigate a significant amount of risk. This isn’t a simple task however, for an organisation to be able to employ efficient risk based patch management it must have a sufficient level of cyber maturity and internal vulnerability scanning accompanied by a dynamic threat intelligence component.

  • Printers Pose Persistent Yet Overlooked Threat

A rash of printer-related vulnerabilities in 2023 have punctuated security expert warnings that printers continue to be a significant vulnerability within companies — especially as remote workers require printing resources or access to corporate printers. So far in 2023, Lexmark advised that a publicly available remote exploit had already targeted a code execution flaw in its printers, HP warned of a vulnerable firmware version on some of its enterprise printers, and Microsoft fixed three remote code execution vulnerabilities in its printer drivers.

Printers remain a likely soft spot in most companies’ attack surface area, particularly because they are not always part of a company’s asset management process and are often left out of security assessments and risk registers. Many organisations don’t know where their printers are, their security status, configuration, monitoring or logging activity. Research has shown that 67% of companies are worried about the risk home printers may pose and only 26% of information technology and cyber security professionals are confident in their organisation’s printing infrastructure security.

  • Employees Are as Likely as Cyber Criminals to Cause Cyber Incidents

Employees and cyber criminals cause similar numbers of data leakages. Kaspersky’s 2022 IT Security Economics survey found cyber-attacks caused 23% of data leakages, while employees caused a similar proportion, at 22%. The rise in employees causing leakages may be linked with more remote working since the pandemic, with new staff laptops, tablets, and virtual private networks (VPNs) featuring among the extra endpoints and systems needing security. Although innocent mistakes or ignoring cyber-security policy were behind most leakages, security managers reported 36% of employee-triggered leakages were deliberate acts of sabotage or espionage. The high number of cyber-incidents stemming from employee action shows all organisations need thorough cyber-security awareness training to teach all staff how to avoid common security mistakes.

  • Over 90% of Organisations Find Threat Hunting a Challenge

Executing essential cyber security operations tasks during the threat hunting process is an increasingly challenging proposition to the vast majority of organisations, with 93% of those polled for a Sophos report saying they find basic security operations a chore.

In the report, “The state of cybersecurity 2023: The business impact of adversaries on defenders”, Sophos said these findings were likely the result of the ongoing cyber security skills shortage, which is creating a domino effect in security operations: a lack of skilled personnel makes investigating alerts take longer, which reduces the security team’s capacity and increases the organisation’s exposure to higher levels of risk.

Organisations that suffer the most are those with revenues of less than $10m (£8m), which are more likely to lack the necessary skillsets, followed by organisations with revenues of more than $5bn, where organisational and system complexity likely play a more prominent role.

  • 75% of Organisations Have Suffered a Cyber Security Breach

Most organisations need stronger security controls to stop cyber security breaches and cyber attacks, according to “The Data Dilemma: Cloud Adoption and Risk Report” from security service edge (SSE) company Skyhigh Security. Key takeaways from the report include:

  • 97% of organisations indicated they are experiencing private cloud problems.

  • 75% have experienced a cyber security breach, threat and/or theft of data.

  • 75% said shadow IT “impairs their ability to keep data secure.”

  • 60% allow employees to download sensitive data to their personal devices.

  • 52% noted their employees are using SaaS services that are commissioned by departments outside of IT and without direct involvement of their IT department.

  • 37% said they do not trust the public cloud to secure their sensitive data.

  • Leak Shows Evolving Russian Cyber War Capabilities

The leak of thousands of pages of secret documentation related to the development of Moscow’s cyber and information operations capabilities paint a picture of a government obsessed with social control and committed to scaling their capacity for non-kinetic interference.

The leaked documents detail methods and training simulations intended to prepare an operator workforce for offensive operations against critical infrastructure targets. Tools revealed by these recent leaks suggest a desire and an ability to extensively map foreign vulnerabilities and make the job of Russia’s cyber conflict operators as accessible and scalable as possible.

This leak reinforces the significant concern regarding the threat posed by Russian cyber forces to firms across the globe.

  • Outsourced Payroll and HR Services Firm Forced to Shut Down After Cyber Attack

Belgian headquartered HR and payroll giant SD Worx has suffered a cyber attack causing them to shut down all IT systems for their UK and Ireland services. While the login portals for other European countries are working correctly, the company's UK customer portal was not accessible. As a full-service human resources and payroll company, SD Worx manages a large amount of sensitive data for their client's employees.

According to the company's general conditions agreement, this data may include tax information, government ID numbers, addresses, full names, birth dates, phone numbers, bank account numbers, employee evaluations, and more.

  • When a Cyber Criminal Steals Personal Data from Your Organisation What Do You Do and Who Do You Need to Inform?

If that happens it might be time for your management to clear their desks. The prospect of financial penalties and reputational damage is very real. You need to know your obligations — for instance, reporting the breach to applicable authorities and regulators within strict timeframes — understand the breach, and prioritise. Then you communicate and remedy. If you haven’t planned well, it’s going to be tough.

You need to understand the data breach. Who is affected — is it staff or customer data? What exactly have the cyber criminals accessed? Consider the type of information: salary details and passport copies, or customer payment information.

If personal data has been lost or compromised, you will likely have an obligation under data protection regulations to report the breach to your applicable data protection authority within 72 hours, and if you are a regulated business there will likely be similar requirements to report to your regulator within a similar timeframe. Knowing your obligations — ideally before any hack takes place — will guide how well you respond.

  • Insider Threat and Ransomware: A Growing Issue

Ransomware is a growing epidemic. 2022 saw a slew of high-profile attacks leading to massive paydays for cyber criminals. Cyber criminals work just as hard to conceal their identities and location as they do to exploit weaknesses and capture valuable data to hold hostage. Organisations not only stand to lose money in this scenario, but the damage to their reputation and trustworthiness in the market can be challenging to recover from. Customers place high trust in the safety of their personal information, and it’s the company they hold accountable – not the thieves – if it slips into the wrong hands.

Even if you have good technical controls, the low-hanging fruit is capitalising on the human element and gaining entrance through a person within your organisation. Insider threats come in all shapes and sizes and roles, including employees, executives, former employees, board members, contractors, and service providers. Insider threats, by their very nature, pose a unique challenge for organisations.

  • How LockBit Changed Cyber Security Forever

LockBit are one of the most prolific ransomware gangs globally, accounting for almost half of ransomware attacks in 2022. They not only maintain a high profile, but they’ve also turned ransom monetisation upside down. Thanks to their innovative approach, the group has claimed 44% of total ransomware attacks launched in 2022. LockBit made history by launching the industry’s first bug bounty program initiated by a ransomware group. The operation invites security experts to uncover vulnerabilities and report them for rewards ranging from $1,000 to a staggering $1 million. This has since been expanded and now offers bounties for creative ways to enhance ransomware operations.

  • Hybrid Work Environments Are Stressing CISOs

The impact of the hybrid workforce on security posture, as well as the risks introduced by this way of working, are posing concerns for CISOs and driving them to develop new strategies for hybrid work security, according to a new report.

Among the report’s most critical findings is the revelation that browsing-based threats ranked as CISOs’ number one concern, regardless of whether their organisation was operating primarily in an in-office, hybrid, or remote setting.

And as for the risks posed by hybrid and remote workers specifically, insecure browsing also topped the list of CISOs’ concerns.

  • Protect Your Data with a USB Condom

USB isn't just a charging protocol, it also allows data to flow back and forth, and while most of the time this data flow is safe, it is possible to create a malicious charging port that can do bad things, such as plant malware on your device or steal your data. Equally, an employee plugging their personal phone into a corporate USB port may present a danger to the corporate network through the phone. A USB condom is a small dongle that adds a layer of protection between your device and the charging point you're attaching it to by blocking the data being transferred through the port. If you must use a charger, cable, or charging port that isn't under your control, it makes sense to use a USB condom.

  • Strategising Cyber Security: Why a Risk-based Approach is Key

By 2027, cyber crime could cost the global economy nearly $24 trillion. Businesses often find themselves at the sharp end of this challenge, and, as such, cyber security is a critical aspect of the modern business landscape. Cyber threats are multiplying and pose serious financial, legal and reputational challenges to organisations.

Modern and effective cyber security management entails more than managing technology risk; it encompasses managing business risk. Organisations must recognise cyber security as a strategic imperative integrated into their overall risk management framework — and this starts at the board level.  In some cases, board members may find it beneficial to seek help in assessing appropriate levels of control.
