Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber threat intelligence 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 Strategic Cyber Stories of the Last Week

Law Firms Face Surge in Targeted Attacks as Hundreds Impacted by Single Attack

An estimated 80 to 200 law firms across the UK were impacted by a cyber attack on a third party firm in their supply chain. The attack was on managed service supplier CTS, who provide services to hundreds of law firms across the UK, especially those with conveyancing departments, and many property sales were impacted nationwide as a result of the attack.

This is against a sharp increase in the number of law firms being singled out by cyber threat actors; only recently, magic circle firm Allen & Overy confirmed themselves as a victim of ransomware.

Approach Cyber Security Awareness Training by Engaging People at All Levels

In the cyber security landscape, human-related factors like social engineering, compromised credentials, and errors are the top causes of breaches. Increased investment in threat detection doesn't guarantee foolproof security. Organisations need a proactive strategy focusing on human risks, a security mindset in employees, and a security culture. According to IBM’s latest data security report, high levels of security training can significantly reduce the impact, cost, and frequency of data breaches.

However, most employee training programmes fail due to staff resistance and lack of management support. The key is convincing leadership of its value. To achieve a successful and impactful security awareness programme, it is important that security teams understand their audiences (leaders, managers, and employees), address their requirements, and effectively communicate the benefits of security training.

Board Support Remains Critical as Majority of CISOs Experience Repeat Cyber Attacks

A recent report found that despite 95% of Chief Information Security Officers (CISOs) receiving budgetary and other support from their organisation after a cyber attack, this largely fails to prevent future incidents, with over half admitting they have experienced multiple “major cyber security incidents” in the last five years.

The report revealed that after an attack 46% of CISOs were given a bigger tech budget, 42% revised their security strategy, 41% adopted new frameworks, and 38% created new roles. However, incidents come with hidden consequences such as revenue loss, rising insurance premiums and declining reputation. CISOs need to have support from the board and executives from the start so that investments can be made in the right technology, processes, and tools. In doing so, a culture of security and vigilance can be instilled from the top down to help protect organisations against evolving threats.

Ransomware Attacks Surge 81% in October as New Threat Actors Emerge

The NCC Group revealed that ransomware attacks have surged by 81% in October 2023, compared to the same period in the previous year. Ransomware gangs have already victimised over 50% more individuals and enterprises in 2023 than during the entirety of 2022. As artificial intelligence, phishing kits and ransomware-as-a-service has improved, so too has the number of threat actors; those who were previously stunted by their technical know-how are now able to gain access to sophisticated attacks.

Hacked Microsoft Word Documents Being Used to Trick Windows Users

Active campaigns carried out by cyber criminals are again using macros within Word documents to deploy malware, in spite of Microsoft’s efforts to stop these types of attacks. Most of the time the actor delivers the Word document via phishing emails, with the aim of convincing the user to click and run the macro. Once run, the malware has then achieved its goal of establishing itself on the victims’ machine and executing its malicious payload.

Mitigating Deepfake Threats in The Corporate World

Deepfakes are synthetic media that are created or manipulated with the desired outcome of convincing the recipient of their legitimacy; and it’s entering the corporate world. Deepfake technology has already been used to impersonate Presidents and financial experts, however there has been an uprise in the number of these attacks. This has left the corporate world questioning existing operational procedures such as callbacks and how they will need to adjust to encompass the changing landscape.

Some of the ways a corporation can mitigate this, is to promote awareness within the workplace, adjust operational procedures to reflect the current landscape, and utilise advanced detection tools.

Black Basta Ransomware Made Over $100 Million From Extortion Alone

The cyber crime operator “Black Basta” has raked in at least $100 million in ransom payments from more than 90 victims since it first surfaced in April 2022. In total, 329 victims worldwide were targeted and research has estimated that at least 35% paid a ransom, with multiple payments over $1 million. Black Basta uses double extortion techniques, where data is both ransomed and exfiltrated. This way, victims are forced to pay to get their data back and not have it published online; the latter itself can lead to regulatory fines.

Long Recovery Times After Cyber Attacks Could Annihilate Your Organisation

In the evolving cyber security landscape, organisations are increasingly investing in detection and prevention measures. However, there's a growing trend of neglecting post-attack recovery. While advanced security tools and technologies are crucial, recent ransomware incidents have shown that recovery is equally vital. Organisations have faced substantial downtime and financial losses due to attacks. Cyber resilience, the ability to bounce back quickly after an attack, is crucial, especially with the rise of remote work.

Budgets often prioritise prevention, leaving organisations ill-prepared for recovery. In 2023, a significant number of companies paid ransoms to regain data. To achieve true cyber resilience, a rebalance in approach is essential, focusing on preparation, response, and recovery alongside detection and prevention, ensuring rapid recovery and safeguarding of valuable assets.

Booking.com Customers Scammed in Novel Social Engineering Campaign

According to new research by SecureWorks, Booking.com customers are being targeted by a novel social engineering campaign that is “paying serious dividends” for cyber criminals. Researchers believe the campaign has gone on for at least a year and it begins by deploying the Vidar infostealer to gain access partner hotels’ Booking.com credentials. This information is then used to send phishing emails to Booking.com customers and trick them into handing over their payment details, in many cases leading to money being stolen. The scam is proving so fruitful that sales of Booking.com portal credentials are commanding sale prices of up to $2,000 in two cyber crime forums.

Stop Panic Buying Your Security Products and Start Prioritising

In the cyber security landscape, impulse buying can lead to costly mistakes. Breaches are now more expensive than ever, underscoring the need to assess cyber security investments. Fear-driven tactics and the quest for a "silver bullet" solution can push organisations, especially smaller ones, into impulsive investments. These decisions may introduce even more risk by failing to integrate with existing systems, or buying systems but failing to configure them properly or utilising them to the fullest extent, leading to a false sense of security. The consequences can be severe, with breaches now costing organisations millions. To navigate this landscape, organisations must assess the real value of cyber security investments. Calculating risk by evaluating likelihood and impact can guide us in making informed decisions. Instead of impulse buying, assign a monetary value to cyber risks for strategic budget decisions in these economic times, ensuring investments align with security and business goals.

A Fifth of UK SMBs Unable to Spot Scams

New data from UK Finance reveals that 17% of UK small and medium-sized businesses (SMBs) struggle to identify online fraud and scam indicators. This is particularly alarming given the rise in authorised push payment (APP) scams in the UK, where fraudsters impersonate trusted entities to deceive victims into transferring money to controlled accounts. In the first half of 2023 alone, criminals stole a reported £42.6 million through such scams, with total losses including consumer impacts reaching £239 million. SMBs are increasingly targeted due to typically fewer anti-fraud and other countermeasures and controls, compared to larger and better protected larger firms. It is important for SMBs to be vigilant and verify payment details directly with suppliers to help avoid these types of scams.

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.

The Human Element- Cyber Security’s Great Challenge

According to Verizon’s 2023 Data Breach Investigations Report, 74% of all breaches involved a human element. It is important for organisations to understand that it is not simply malicious employees or employees falling for social engineering attacks; it includes things such as negligent, or intentional but not malicious actions. In fact, a recent separate report by Kaspersky found that 26% of incidents over the past two years involved the result of intentional security protocol violations; in comparison, external hacking attempts made up 20%.

Further, Kaspersky found 25% of incidents occurred due to neglecting system software or application updates, followed by 22% resulting from deliberate use of weak passwords or failing to change them promptly, and 18% from staff visiting unsecured websites. One potential cause for these incidents is a lack of training on why such protocols need to be followed.

Black Arrow provides live in person and online instructor lead cyber security training including Cyber Risk and Governance Workshops for Senior Leadership, and Awareness, Behaviour and Culture Training for employees and contractors.

Good Cyber Hygiene is a Strategic Imperative for SMEs, Report Shows

Small or large, no company is immune to a cyber attack and therefore good cyber hygiene is an imperative for all. Whilst large firms may already have more mature defences in place, smaller firms are definitely catching on to this, with 47% of respondents to a recent survey stating they were more worried about their organisation’s security posture now than compared to six months ago.

The survey found that ransomware (35%), software vulnerability exploits (28%) and using the same password across different applications (25%) were amongst the largest concerns. Interestingly, in a separate report, 44% of incidents were found to lack any element of malware, indicating that attackers are moving beyond traditional methods. The same report found 65% of cases included remote monitoring and management tools as the vector for initial access, something a number of organisations do not secure.

Business email compromise (BEC) attacks are also a key concern for businesses of all sizes but can be especially damaging to smaller organisations for whom the financial loss can be devastating.

Despite Increasing Ransomware Attacks, Some Companies are in Denial

A recent study has highlighted a contradiction in the way organisations perceive ransomware threats. Although many do not consider themselves likely targets, they are, nevertheless, bolstering their security measures, expanding their teams, and fortifying cyber defences, acknowledging the risks despite their assumed invulnerability.

Simultaneously, ransomware tactics are undergoing significant changes. The past three quarters have seen a marked increase in double-extortion attacks, with data leaks from these incidents rising by 50% compared to the previous year. This trend is predominantly driven by a few active groups, some newly emerged this year, amplifying the threat landscape.

In a tactical shift, the ransomware group ALPHV, also known as Blackcat, has lodged a formal complaint with the US Securities and Exchange Commission (SEC) against a victim for failing to comply with new disclosure regulations. Meanwhile, LockBit, infamous for attacks on high-profile targets, is modifying its extortion tactics due to lower-than-anticipated ransom returns. These developments point to an evolving and adaptive ransomware environment.

A Single Supply Chain Related Ransomware Incident Spurred UK Decision Makers to Spend Big on Cyber as Latest Victim Count exceeds 2.6K Organisations and 77M People

It is reported that 2,620 organisations and more than 77 million individuals have been impacted to date by the MOVEit supply chain ransomware attack, with millions in the past week alone having received notifications that their information had either been accessed, leaked, or both.

In a survey involving directors of UK companies with over 500 seats that had suffered a ransomware or extortion attack in the past 18 months, it was found that 24% had become significantly more anxious about ransomware attacks as a direct result of the MOVEit breach, and 66% were slightly more anxious. This anxiety translated into action, with 42% of respondents investing more into backup and recovery, and 29% tweaking existing cyber strategies. 29% had taken the decision to amend their existing cyber strategies. Staff training was also found to rise, with 42% looking to spend on skills development and 40% upping their investment in training.

The True Cost of a Ransomware Attack

While the demand is often financial, the impact and reach of ransomware goes far beyond the ransomware demand. Alongside the financial impact, comes the reputational impact, loss of customers, resources in returning to business as normal and time lost in recovery. For some companies, it can take months to return to where they were before and for others, it marks the end of their organisation.

For an attacker, it doesn’t matter. Their goal is not limited by the size or sector of an organisation and it is therefore imperative that every organisation is prepared for the event of an 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.

Largest Study of Its Kind Shows Outdated Password Practices Are Putting Millions at Risk

A recent study has exposed serious flaws in passwords on the internet, revealing that three out of four popular websites are compromising user security by not meeting basic password standards. The study examined 20,000 websites, finding many allowed simple passwords, didn’t block common ones and adhered to outdated complexity requirements. It was found that over half the websites accept passwords of six characters or fewer, with 75% not requiring the advised minimum of eight characters, and 30% not supporting spaces or special characters. The study showcases the gap in security measures implementation across the web and emphasises the importance of ongoing improvement in web security standards.

The problem is further exacerbated by employees using work email for non-work approved websites and reusing the same passwords, meaning any breach of a compromised site hands the user’s credentials to an attacker. Further, many organisations are not even aware this is going on.

Source: [TechXplore]

Cyber Security Investment Involves More Than Just Technology

C-suite business leaders and senior IT professionals within large organisations, found that the top five cyber security investment areas were technologies (49%), threat intelligence (46%), risk assessment (42%), cyber insurance (42%), and third-party risk management (40%). Fewer organisations highlighted technology as good value for money in 2023 (49%) than in 2022 (58%). suggesting an awareness that technology investments go hand-in-hand with investing in governance and personnel to effectively enable and manage the technology.

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.

Questions Leaders Must Ask Themselves on Security Culture

In today's corporate landscape, there's a growing emphasis on the human aspect of cyber security, with Stanford University research indicating that about 88% of data breaches result from employee errors. Companies are now focusing on enhancing security awareness through marketing campaigns and integrating cyber security performance into job reviews. This shift acknowledges that as technological defences evolve, cyber attackers increasingly exploit human vulnerabilities, as evidenced by major ransomware incidents like those impacting Colonial Pipeline and JBS Foods.

Developing a strong security culture is essential, by complementing robust policies with ingraining security-minded beliefs and behaviours in employees. Key to this is the role of leadership in embedding and continuously assessing this culture. This involves evaluating training effectiveness, reporting mechanisms, proactive security approaches, and the impact of security initiatives, while also considering the complexity of human behaviour and the example set by top management. Emphasising these aspects is crucial for maintaining a secure and resilient organisational environment, and in so doing protecting an organisation's reputation and financial integrity.

There’s a Crossover Between Organised Crime, Financial Crime, and Nation-State Crime

The convergence of organised crime, financial crime, and nation-state crime is a growing concern in today’s interconnected world. This crossover, driven by the digital revolution, globalisation, economic factors, and state fragility, is reshaping the global criminal landscape. Organised crime syndicates, traditionally involved in activities like drug trafficking and extortion, are now branching out into financial crimes, offering higher profits with lower risks.

Financial crime, once the domain of individual fraudsters and white-collar criminals, has become a lucrative venture for organised crime groups. They exploit the global financial system to launder proceeds of crime, finance their operations, and evade law enforcement. Nation-state crime, involving state-sponsored or state-condoned criminal activities, often overlaps with organised and financial crime. Some governments turn a blind eye to these activities, while others actively support them for political, economic, or strategic reasons.

Cyber Attack on British Library Highlights Lack of UK Resilience

A recent ransomware attack on the British Library has spotlighted the vulnerabilities in the UK's public sector IT infrastructure, amid rising state-backed cyber attacks. This major incident, which caused a significant technical outage at the library, underscores the concerns of cyber intelligence experts about the government's inadequate investment in cyber resilience in critical areas like education, healthcare, and local government. The hacking group Rhysida, targeting essential infrastructure, claimed responsibility and auctioned stolen data, including British Library employees’ passports, for 20 bitcoin (approximately £600,000).

The attack on the British Library, a key public service institution, highlights the escalating threat of ransomware attacks and their potential exploitation by state actors. The UK’s National Cyber Security Centre (NCSC) has reported a significant increase in cyber attacks in 2023, with incidents more than doubling compared to the previous year. In response, the UK government, which had already allocated £2.6bn for cyber security improvements and IT system updates, is actively assessing the situation with the support of the National Protective Security Authority.

Organisations Rethink Cyber Security Investments to Meet NIS2 and DORA Directive Requirements

The European Union (EU) is seeking to improve cyber resilience across all member states by bringing in two new regulations: the Digital Operational Resilience Act (DORA), which focuses on financial services companies, and its counterpart the Network and Information Systems Directive (NIS2). The effects of the two regulations are likely to be wider reaching, bringing in more stringent processes and controls and redefining service provision to organisations.

With NIS2 coming into effect in October 2024, the mandatory directive will have teeth, with strict penalties for non-compliance for both the business and senior board personnel, who can be held directly accountable and prevented from holding similar positions in the future. It also aims to increase intelligence sharing between member states and enhance supply chain security. This latter measure will see the directive have a global impact.

Many organisations supplying services to firms that fall under DORA and NIS2 will themselves be subject to the full force of the regulations, with many of these suppliers, including IT providers, unaware that this will have far reaching ramifications for them and their ability to continue to provide these services.

The Cyber Security Lawsuit Boards are Talking About

For the last month, an under-the-radar lawsuit has privately been a hot topic of conversation in boardrooms and corporate security departments alike. The lawsuit involved the Securities and Exchange Commission (SEC) accusing SolarWinds and their CISO of fraud. SolarWinds, like many organisations, had disclosed some facts, however what was reported was not sufficient to satisfy the regulator. The lawsuit is the first in which the SEC has charged a company with intentional fraud related to cyber security disclosures and it paints a picture for the wider movement of the cyber landscape. Whilst the SEC is US based you can expect regulatory counterparts in other jurisdictions globally to follow suit.

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

Microsoft Sees Rampant Log4j Exploit Attempts, Testing

Microsoft says it’s only going to get worse: It’s seen state-sponsored and cyber-criminal attackers probing systems for the Log4Shell flaw through the end of December.

No surprise here: The holidays bought no Log4Shell relief.

Threat actors vigorously launched exploit attempts and testing during the last weeks of December, Microsoft said on Monday, in the latest update to its landing page and guidance around the flaws in Apache’s Log4j logging library.

“We have observed many existing attackers adding exploits of these vulnerabilities in their existing malware kits and tactics, from coin miners to hands-on-keyboard attacks,” according to Microsoft.

https://threatpost.com/microsoft-rampant-log4j-exploits-testing/177358/

Warning: Log4j Still Lurks Where Dependency Analysis Can’t Find It

The best programming practice to include a third-party library in source code is to use the import command. It is the easiest way to do it, and it is also the way that most dependency analysis programs work to determine if a vulnerable library is in play. But any time code is included without calling it as an external package, traditional dependency analysis might not be enough to find it — including when Java coders use a common trick to resolve conflicting dependencies during the design process.

A new study by jFrog found that 400 packages on repository Maven Central used Log4j code without calling it as an external package. Around a third of that came from fat jars — jar files that include all external dependencies to make a more efficient product. The remainder came from directly inserting Log4j code into the source code, including shading, a work-around used when two or more dependencies call different versions of the same library in a way that might conflict.

While 400 may not seem like a lot for Maven Central, where Google found 17,000 packages implementing the vulnerable Log4j library, some of the 400 packages unearthed by JFrog are widely used.

Hackers Sending Malware-Filled USB Sticks to Companies Disguised as Presents

The "malicious USB stick" trick is old but apparently it's still wildly popular with the crooks.

Word to the wise: If a stranger ever offers you a random USB stick as a gift, best not to take it.

On Thursday, the FBI warned that a hacker group has been using the US mail to send malware-laden USB drives to companies in the defence, transportation and insurance industries. The criminals’ hope is that employees will be gullible enough to stick them into their computers, thus creating the opportunity for ransomware attacks or the deployment of other malicious software, The Record reports.

The hacker group behind this bad behaviour—a group called FIN7—has gone to great lengths to make their parcels appear innocuous. In some cases, packages were dressed up as if they were sent by the US Department of Health and Human Services, with notes explaining that the drives contained important information about COVID-19 guidelines. In other cases, they were delivered as if they had been sent via Amazon, along with a “decorative gift box containing a fraudulent thank you letter, counterfeit gift card, and a USB,” according to the FBI warning.

Patch Systems Vulnerable To Critical Log4j Flaws, UK And US Officials Warn

One of the highest-severity vulnerabilities in years, Log4Shell remains under attack.

Criminals are actively exploiting the high-severity Log4Shell vulnerability on servers running VMware Horizon in an attempt to install malware that allows them to gain full control of affected systems, the UK’s publicly funded healthcare system is warning.

CVE-2021-44228 is one of the most severe vulnerabilities to come to light in the past few years. It resides in Log4J, a system-logging code library used in thousands if not millions of third-party applications and websites. That means there is a huge base of vulnerable systems. Additionally, the vulnerability is extremely easy to exploit and allows attackers to install Web shells, which provide a command window for executing highly privileged commands on hacked servers.

The remote-code execution flaw in Log4J came to light in December after exploit code was released before a patch was available. Malicious hackers quickly began actively exploiting CVE-2021-44228 to compromise sensitive systems.

‘Elephant Beetle’ Lurks For Months In Networks

The group blends into an environment before loading up trivial, thickly stacked, fraudulent financial transactions too tiny to be noticed but adding up to millions of dollars.

Researchers have identified a threat group that’s been quietly siphoning off millions of dollars from financial- and commerce-sector companies, spending months patiently studying their targets’ financial systems and slipping in fraudulent transactions amongst regular activity.

The Sygnia Incident Response team has been tracking the group, which it named Elephant Beetle, aka TG2003, for two years.

In a Wednesday report, the researchers called Elephant Beetle’s attack relentless, as the group has hidden “in plain sight” without the need to develop exploits.

https://threatpost.com/elephant-beetle-months-networks-financial/177393/

Sonicwall: Y2k22 Bug Hits Email Security, Firewall Products

SonicWall has confirmed today that some of its Email Security and firewall products have been hit by the Y2K22 bug, causing message log updates and junk box failures starting with January 1st, 2022.

The company says that email users and administrators will no longer be able to access the junk box or un-junk newly received emails on affected systems.

They will also no longer be able to trace incoming/outgoing emails using the message logs because they're no longer updated.

On January 2nd, SonicWall deployed updates to North American and European instances of Hosted Email Security, the company's cloud email security service.

It also released fixes for its on-premises Email Security Appliance (ES 10.0.15) and customers using firewalls with the Anti-Spam Junk Store functionality toggled on (Junk Store 7.6.9).

Hackers Use Video Player To Steal Credit Cards From Over 100 Sites

Hackers used a cloud video hosting service to perform a supply chain attack on over one hundred real estate sites that injected malicious scripts to steal information inputted in website forms.

These scripts are known as skimmers or formjackers and are commonly injected into hacked websites to steal sensitive information entered into forms. Skimmers are commonly used on checkout pages for online stores to steal payment information.

In a new supply chain attack discovered by Palo Alto Networks Unit42, threat actors abused a cloud video hosting feature to inject skimmer code into a video player. When a website embeds that player, it embeds the malicious script, causing the site to become infected.

Cyber World Is Starting 2022 In Crisis Mode With The Log4j Bug

The cyber security world is starting off 2022 in crisis mode.

The newest culprit is the log4j software bug, which cyber security and Infrastructure Security Agency (CISA) Director Jen Easterly called “the most serious vulnerability I have seen in my decades-long career.” It forced many cyber security pros to work through the holidays to protect computer systems at Big Tech firms, large and small companies and government agencies.

But crises like log4j have become the norm rather than the exception during the past few years.

Last year kicked off with the SolarWinds hack — a Russian government operation that compromised reams of sensitive information from U.S. government agencies and corporations.

Digital threats of all sorts are growing far faster than the capability to defend against them. If past is prologue, 2022 is likely to be a year of big hacks, big threats and plenty more crises.

“We’re always in crisis is the long and short of it,” Jake Williams, a former National Security Agency (NSA) cyber operator and founder of the firm Rendition Infosec, told me. “Anyone looking for calm rather than the storm in cyber is in the wrong field.”

Everything You Need To Know About Ransomware Attacks and Gangs In 2022

Ransomware is a lucrative business for criminals. It is paying off, and it is working.

According to a recent Trend Micro report, a staggering 84% of US organisations experienced either a phishing or ransomware attack in the last year. The average ransomware payment was over $500,000.

Bad actors want to keep cashing in. So they’re going as far as creating ransomware kits as a service (Ransomware as a Service) to be sold on the dark web and even setting up fake companies to recruit potential employees.

Many ransomware gangs function like real companies — with marketing teams, websites, software development, user documentation, support forums and media relations.

If the “companies” run by ransomware gangs can operate with minimal expenses and mind-blowing revenues, what’s stopping them from growing in number and size?

Why the Log4j Vulnerability Makes Endpoint Visibility and Zero Trust Security More Important Than Ever

The Apache Log4j vulnerability is one of the most serious vulnerabilities in recent years—putting millions of devices at risk.

IT organisations worldwide are still reeling from the discovery of a major security vulnerability in Apache Log4j, an open-source logging utility embedded in countless internal and commercial applications.

By submitting a carefully constructed variable string to log4j, attackers can take control of any application that includes log4j. Suddenly, cyber criminals around the world have a blueprint for launching attacks on everything from retail store kiosks to mission-critical applications in hospitals.

If security teams overlook even one instance of log4j in their software, they give attackers an opportunity to issue system commands at will. Attackers can use those commands to install ransomware, exfiltrate data, shut down operations — the list goes on.

How should enterprises respond to this pervasive threat?
