Black Arrow Cyber Advisory 04 December 2023 – Apple, Google, ownCloud, Zoom and Zyxel Vulnerabilities Summary

Black Arrow Cyber Advisory 04 December 2023 – Apple, Google, ownCloud, Zoom and Zyxel Vulnerabilities Summary

Executive summary

Apple, Google, ownCloud and Zoom have all addressed vulnerabilities in their products which could be exploited by an attacker. The vulnerabilities could lead to remote code execution. The vulnerabilities impacting Google and ownCloud are actively being exploited by malicious actors.

Apple

Two new Zero-Days impacting Apples WebKit Browser were fixed in emergency updates. The two vulnerabilities allow attackers to gain access to sensitive information via an out-of-bounds read weakness and gain arbitrary code execution via maliciously crafted webpages.

Google Chrome

Google has addressed several vulnerabilities, including one actively exploited zero-day. The actively exploited zero-day is caused by a weakness within the Skia open-source 2D graphics library and can lead to remote execution. The vulnerability has been recorded as actively exploited.

ownCloud

Three vulnerabilities in the open-source file sharing software, ownCloud could disclose sensitive information and allow an attacker to modify files, if exploited. As a fix, ownCloud is recommending to delete the "owncloud/apps/graphapi/vendor/microsoft/microsoft-graph/tests/GetPhpInfo.php" file and disable the 'phpinfo' function. It is also advising users to change secrets like the ownCloud admin password, mail server and database credentials, and Object-Store/S3 access keys. One of the vulnerabilities has already been recorded as being actively exploited by malicious actors

Zoom

A vulnerability in Zoom could allow threat actors to take over meetings and steal data has been patched. Research has stated that the flaw was first discovered in June 2023. There are no reports of active exploitation in the wild at this time.

Zyxel

Zyxel have documented multiple security flaws in a range of products, including firewalls, access points and network attached storage (NAS) Devices, warning that unpatched devices are at risk of authentication bypass, command injection and denial-of-service attacks.

What’s the risk to me or my business?

There is a risk that that running unpatched versions of the above products will leave users at open to having the confidentiality, integrity and availability of their information compromised.

What can I do?

Black Arrow recommends organisations check whether they are running vulnerable versions of the above products, and if so, these should be updated to patched versions. Further information can be found below.

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.
