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

A “Ridiculously Weak“ Password Causes Disaster for Spain’s Number 2 Mobile Carrier

Spain’s second largest mobile operator, Orange España, suffered a major outage after an unknown party obtained a “ridiculously weak” password and used it to access an account for managing the network that delivers the company’s internet traffic. The attacker had posted the account they had compromised, and researchers found that the associated system had been infected with a Raccoon type infostealer back in September of 2023. The compromised account was Orange’s RIPE administrator account, with the password “ripeadmin”. The incident led to a 50% drop in connections for a 4 hour period, and  underscores the critical importance of robust cyber security measures, including strong passwords, and serves as a stark reminder that even seemingly minor oversights can lead to significant disruptions.

Russia Kyivstar Hack Should Alarm the West, Ukraine Security Chief Warns

If Ukraine's core telephone network can be taken out, organisations in the West could easily be next, Ukraine's SBU chief says. December's cyber attack on Ukrainian telecommunications operator Kyivstar by Russian-backed threat actor ‘Sandworm’ dealt a catastrophic blow to the telecoms provider, according to Illia Vitiuk, head of the Security Service of Ukraine's (SBU) cyber security department. It is believed that although the attack took place in December 2023, the threat actors likely had access to Kyivstar systems since May 2023.

23andMe Tells Victims It’s Their Fault Their Data Was Breached

A cyber incident at DNA data firm 23andMe started with credential stuffing 14,000 user accounts. Credential stuffing is the process by which a malicious actor uses previously harvested usernames and passwords from earlier unrelated breaches to break into other sites and services. Many of the 14,000 accounts had opted-in for a feature whereby information is shared with relatives, which meant that once compromised, attackers had access to 6.9 million users: nearly half of the user base.

Facing over 30 lawsuits from victims, 23andMe is now blaming victims, according to letters seen by victims. 23andMe stated “users negligently recycled and failed to update their passwords following these past security incidents, which are unrelated to 23andMe”. This has caused divide in the cyber world; on one side, recycling and failing to update passwords is poor cyber hygiene and on the other hand, there are technical controls that could have better prevented this type of well known and common attack.

Financial Sector Faces More Cyber Attacks Than Other Sectors

A recent study found that more than three-quarters (77%) of financial organisations detected an attack on their infrastructures in 2023, compared with around two-thirds (68%) of other sectors. In particular, the study found that financial workers were at a higher than average risk of phishing compared to other workers. Despite their target attractiveness, only three-quarters (73%) of the financial sector respondents said that they have a cyber security policy in place or will do so within the next year. A separate report from Kaspersky stated that the financial sector is poised to experience an influx of artificial intelligence based attacks 2024, adding to the fire.

An Innocent-Looking Instagram Trend Could Be a Gift to Hackers

A recent trend that has picked up traction at the end of December on social media apps such as Instagram and TikTok, encourages their followers to “get to know them better”. This trend gets people to answer a popular template, freely giving away personal information such as their height, date of birth, and various details that they feel strongly about including favourite food and phobias. While these questions may seem harmless, these sorts of personal details are used by companies for security questions, for example when a person wants to reset their password. Hackers can use this information to easily social engineer victims or impersonate them to get access to their accounts.

Cyber Criminals Shared Millions of Stolen Records During Holiday Break

While many people unwind and enjoy their time off during the festive season, cyber criminals remain active. In fact, they leaked approximately 50 million records containing sensitive personal information during this period. These data breaches were not limited to the West; they had a global impact, affecting individuals in various countries such as Peru, Australia, South Africa, and more. It is important to note that not all the data leaks were recent; some appeared to be remnants of older incidents. For instance, some of the leaked data belonged to customers of the credit company Klarna, which was rumoured to have experienced a breach back in 2022, although it was never publicly confirmed. This ‘Free Leaksmas’ event, as it’s been dubbed, underscores the extensive global reach and serious consequences of these cyber criminal activities.

Law Firm that Handles Data Breaches was Itself Hit by Data Breach

Orrick, Herrington & Sutcliffe, a law firm specialising in managing security incidents for other companies, has disclosed more details of the cyber attack it itself experienced in March 2023. The breach compromised the sensitive health and personal information of over 637,000 individuals. The stolen data was linked to client organisations and included the names of individuals alongside their social security numbers, medical details, and financial information. Despite the firm's expertise in cyber security, the attack highlights the pervasive risk of data breaches, even among those who advise on such matters. Orrick's delayed response and subsequent legal settlements underscore the importance of proactive security measures and swift action in the wake of a breach. This incident serves as a stark reminder to all organisations of the need for robust cyber defences and transparent communication strategies in today's digital landscape. The law firm has recently settled in principle to resolve four class action lawsuits that accused Orrick of failing to inform victims of the breach until months after the incident.

Nigerian Hacker Arrested for Stealing Millions from Charities

A Nigerian national, Olusegun Samson Adejorin, has been arrested for charges relating to business email compromise attacks that caused a charitable organisation in the US to lose more than $7.5 million. Adejorin had purchased a credential harvesting tool to steal login credentials, which were used to send emails to the charity’s financial service provider. The emails requested and authorised a transfer of $7.5 million, which the investment services provider believed it was paying to the charity whereas it was paying into a bank account controlled by the attacker.

Cyber Criminals Implemented Artificial Intelligence for Invoice Fraud

A cyber criminal gang known as GXC Team has been seen selling an artificial intelligence tool for creating fraudulent invoices. The tool, known as Business Invoice Swapper, scrutinises compromised emails that are fed to it, looking for emails which mention invoices or include invoice attachments. It then alters the details of the intended recipient to details specified by the perpetrator. This altered invoice then either replaces the compromised one, or is sent to a predetermined set of contacts.

Shadow IT Threatens Corporate Cyber Security, Study Reveals

With remote working becoming more and more prevalent, organisations are finding themselves at risk of cyber threats due to what is known as shadow IT; this is any software, hardware or IT resource used without the IT department’s approval, knowledge or oversight. A study by Kaspersky found of the 77% of companies that had suffered from cyber incidents over the past two years, 11% of these were directly caused by the unauthorised use of shadow IT.

Source: [Security Brief]

Escalating Cyber Threats: Bots, Fraud Farms, and Cryptojacking Surge

In the constantly evolving cyber threat landscape, 2023 has witnessed a notable surge in the use of bots, fraud farms, and cryptojacking. A new report found that 73% of web and app traffic this year has been attributed to malicious bots and fraud farms, indicating a significant shift towards automated cyber attacks. This trend poses a heightened risk to the ecommerce sector, where cyber criminals exploit API connections and third-party dependencies.

Furthermore, the surge in cryptojacking, marked by a 399% increase, reveals a diversifying strategy among cyber criminals, targeting critical infrastructure with sophisticated methods. These developments serve as a crucial reminder for organisations to bolster their cyber defences and adopt a proactive stance against these emerging and increasingly automated threats.

Putin has Declared a Cyber War on Britain

This year over 2 billion people will vote for new governments across the world, and it is crucial to be aware of upcoming threats to these elections from foreign powers. In particular, Russia is notorious for deploying bots, trolls, and deepfakes, which are techniques used to manipulate information and influence public opinion. These malicious actors are adept at spreading misinformation and disinformation, often with the goal of interfering in elections. With the upcoming UK General Election in 2024 and the US Presidential Election also falling this year, it is imperative to exercise caution and discernment when consuming online content. Not everything we see can be taken at face value.

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

66 Percent of Businesses Don't Understand Their Cyber Risks

A survey has found that 67% of organisations have experienced a breach requiring attention within the last two years, despite having traditional security measures in place. Worryingly, 66% self-reported having limited visibility and insight into their cyber risk profiles.

83% of organisations agreed that a comprehensive cyber risk reduction strategy would yield a reduction in the likelihood of a significant cyber incident occurring, yet a number of organisations are finding it difficult to implement this and as a result are looking for outside assistance too. The report found that 93 percent of organisations plan to offload specific segments of cyber risk reduction workstreams or projects to security service providers within the next two years.

Massive Supplier Cyber Breach Puts London’s Metropolitan Police on Red Alert After Officer and Staff Details Hacked

All 47,000 personnel working for the Met Police were warned of the risk their photos, names and ranks having been stolen when cyber crooks penetrated the IT systems of a contractor printing warrant cards and staff passes. The supplier had access to names, ranks, photos, vetting levels and pay numbers of officers and staff, but did not hold information such as addresses, phone numbers or financial details.

The attack shows the importance of understanding the supply chain, and what access your supplier has access to. Without knowing who has your data, and what data, you will be left clueless if a breach on a supplier occurs.

Pay our Ransom Instead of a GDPR Fine, Cyber Crime Gang Tells Targets, as Attacks Against Small Businesses Ramp Up

Ransomware actors are always evolving their tactics, with gangs now telling victims if they don’t pay, then they will face fines under data protection laws. Additionally, small businesses are on the radar, partially due to them being easier targets for actors; some gangs have shifted from asking for millions from a large organisation, to requesting small ransoms from multiple small businesses.

As a result in both the number and sophistication of ransomware attacks, 80% of organisations expect their spending to increase. Not every organisation has an unlimited budget and so it is important that organisations are able to prioritise and allocate their budget effectively, to give them the most protection that their budget allows, especially small to medium-sized businesses.

Survey Finds In-house Counsel Cyber Anxiety Skyrocketing

In a recent report, only 25% of legal professionals said they felt fully prepared to deal with a cyber attack, with 78% ranking the task of shielding their organisation from cyber attacks as the greatest regulatory concern over the next 12 months; previously, this figure was only 30% in 2021.

There has been a growing number of attacks, due to the sensitive data that is held and the number of attacks will continue to rise. With regulatory concerns adding to this, in-house counsel should be looking to have their concerns heard and drive the organisation to bolster their defences, and this may include outsourcing expert advice to make sure it is done correctly.

58% of Malicious Emails Contained Spoofed Content

According to a recent report, 58% of malicious emails contained spoof content and spam emails had increased by 30% from Q1 to Q2 2023. The report identified a surge in the number of uses of QR codes as a primary attack method, showing that attack methods are evolving, and in some cases, choosing not to use traditional methods.

The report reinforces the need for constant user education training, to reduce the risk of an employee falling for a phishing email. With this training, new evolving techniques such as that with QR codes, should also be addressed.

Cyber Attacks Remain a Top Concern for Organisations Across All Industries

Cyber attacks remain a top threat to organisations’ ability to do business across all industries. When asked in a recent report, 18% of respondents reported that cyber attacks threatened or disrupted their business.

With cyber attacks being a huge concern, many organisations have an incident response plan in place; yet despite this, nearly one quarter (23%) of companies surveyed have either never conducted tests or are unsure if their teams have tested. Cyber incidents are a matter of when, not if, and a strong incident response plan is always needed and can prevent a bad situation from being made worse by doing the wrong things in the immediate aftermath of an attack.

BYOD Security Gap: Survey Finds 49% of European Firms Unprotected

A recent survey found that a concerning 49% of European businesses are operating without having a formal bring-your-own-device (BYOD) policy, highlighting a lack of visibility and control over such devices. The report found that organisations are concerned about compliance-based issues, with 43% noting increased worries.

The benefits of BYOD are clear, allowing organisations to save money and eliminate the need for multiple devices. But without a formal BYOD policy, organisations are risking having employees bring in devices that are effectively invisible to IT. This means that the vulnerabilities that come with it, and the risks it can bring, also go unnoticed. To mitigate the risk, a formalised BYOD policy is required.

13% of Employees Admit to Falling for Phishing Attacks Working at Home, 9% Would Wait to Report After the Weekend

In a recent report, it was found that 13% of employees admitted they had fallen for a phishing attack whilst working from home. Rather worryingly, 21% said they would continue working business as usual in the event of falling victim to a phishing attack whilst working remotely on a Friday, with 9% indicating they’d wait until after the weekend to report it, effectively, giving the attacker a 48 hour period in which they go unnoticed, if the employee even remembers to report it on the Monday.

It is important that users are educated, both on spotting phishing attacks and the reporting process, so that organisations can be best protected. By providing regular and effective user training, employees will be at less risk of falling victim to a phishing attack, even from home. Additionally, by understanding the reporting process and why there is a need to report as soon as possible, organisations will shorten their detection time.

Numbers Don't Lie: Exposing the Harsh Truths of Cyber Attacks in New Report

In their most recent quarterly report, BlackBerry focused on a 90-day window, identifying over 1.5 million malware-based attacks, over 200,000 unique attacks, 17,000 attacks per day and 12 per minute to name a few. The report found that financial institutions were amongst the most targeted.

Source: [The Hacker News]

Kroll’s Breach Highlights SIM-Swapping Risk

A recent supply chain breach at Kroll, the risk and financial advisory firm, affected downstream customers and exposed personal information on hundreds of claimants in bankruptcy proceedings. The breach occurred when a threat actor had transferred an employee’s phone number to a device in the attackers possession, which was then subsequently used to access sensitive information.

In this attack, the actor had convinced T-Mobile to port the employee’s number over, allowing the actor to access files containing bankruptcy details. A mitigation recommended for this is to ask your network provider if they offer port freeze or number lock, to protect it from unauthorised transfer.

Source [Dark Reading]

Reducing The Risk of AI, What Can You Do?

Threat actors' use of generative AI has fuelled a significant rise in attacks worldwide during the last 12 months according to a recent report. Yet despite this, AI is still seen as a positive thing for organisations, with the power of generative AI quickly realised.

Certainly, AI can be used in the organisation to increase efficiency and automate tasks, but it must be used with vigilance. Organisations implementing AI should have governance over the usage of AI to eliminate the chance of data leaking. This governance may include policies, procedures and approved AI software.

Debunking Popular Cyber Security Myths

At a time when cyber security is a constant feature in the news and our daily lives, it is important to debunk a few myths surrounding it. One of the biggest, is the assumption that cyber defence is all about the technical controls; in fact, 89% of cyber attacks involved social engineering. The prevalence of social engineering further shows that strong passwords, firewalls and antivirus are not enough; what’s the use in having a password that takes years to crack if you hand it over to someone?

When we think cyber security, we often think of external threat actors, but insider risk is a real threat: whether by malicious actions, negligence or misunderstanding, those inside your organisation can be a real risk to your organisation.

So what’s the take home? Cyber is more than just technology, and it is not just an outside attacker. Organisations’ cyber efforts should focus on more than just the technical requirements; by having things such as user education training, organisations can mitigate their cyber risk.

3 Malware Loaders Responsible for 80% of Intrusions

Three malware loaders, QBot, SocGholish, and Raspberry Robin, are responsible for 80 percent of observed attacks on computers and networks so far this year. The malware are all distributed differently; Qbot is typically deployed through a phishing email, SocGholish is downloaded without user interaction, and Raspberry Robin is through USB devices.

MOVEit Hack Shows Attackers Still Use Old Tricks

SQL injection has been around for a quarter of a century, yet it still features amongst the top 10 list of security vulnerabilities. In fact, SQL injection was the method of attack for the infamous MOVEit hacks, which has impacted over 700 organisations, with the number still growing.

The MOVEit attack highlights just how easily old, over-looked vulnerabilities can be used to target an organisation. Consider your organisation now: are there any legacy systems or software in place?

Source: [Dark Reading]

Barracuda Thought it Drove 0-day Hackers out of Customers’ Networks. It was Wrong.

In late May, security vendor Barracuda had released a patch for their email security gateway (ESG), which was being actively exploited. Having already accounted for this, the threat actors utilised a new attack, which meant infected devices would reinfect themselves, effectively negating Barracuda’s patch. Unfortunately, this meant that for a while, Barracuda thought it was in the clear, when it was still under attack.

Upon realising this, Barracuda’s security advisory changed from recommending a patch to requiring an immediate replacement of compromised ESG appliances, regardless of the patch level. This shows the need for organisations to keep up to date with the latest threat intelligence, as missing the second update could mean infected devices are still in the wild, with organisations under the false perception that they were safe.
