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.

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.

Top Cyber Stories of the Last Week

Overconfident Organisations Prone to Cyber Breaches

A study found that 95% of UK enterprises were very confident or somewhat confident that they do not have gaps in their security controls, yet despite this, 69% have fallen victim to a cyber attack in the last two years. One of the reasons given for this false sense of confidence was the belief that more tools meant more security; worryingly, 45% of organisations struggled with the implementation of tools due to the need for expertise. Attackers are constantly adapting their tactics to bypass the security controls that most organisations implement. It is difficult for IT teams and business leaders to maintain an objective assessment of how effective their chosen security controls are against today’s attackers. Black Arrow provides the impartial and expert advice that businesses require, including a free initial assessment, with no vested interest other than helping our clients achieve pragmatic and proportionate security.

Board Members Struggling to Understand Cyber Risks

Board members frequently struggle to understand cyber risks, putting businesses at higher risk of attacks, a new report has found. The report noted that Board interest is being piqued as a result of growing media reporting of cyber incidents, a heightened Board focus on operational resilience post-pandemic, investor pressure and a tightening regulatory environment.

Worryingly, despite the increase in interest and increased internal and external focus on cyber risk, a number of Board-level respondents reported that they felt scared or embarrassed to ask their CISO for fear of exposing their lack of understanding.

Cyber Criminals are Targeting Top Executives and Could be Using Sensitive Information to Extort Them

Senior executives in today's evolving work landscape face growing cyber security threats, including extortion and device theft. The rise of ‘workcations’, which blend work and leisure, has blurred professional and personal boundaries, exposing leaders to heightened risks, and necessitating a strong focus on cyber security.

These executives are particularly attractive targets due to their access to critical information and decision-making authority. To protect their organisations, they must prioritise robust security measures, such as stronger passwords, anti-theft safeguards for devices, multi factor authentication, and, where appropriate or necessary, the use of virtual private networks. As guardians of their businesses' well-being, executives carry the responsibility of upholding stringent cyber security practices, ensuring that the benefits of remote work do not compromise their organisations' security.

Cyber Attacks Reach Fever Pitch in Q2 2023

A report has found the global landscape of increasing digitisation, political unrest, the emergence of AI and the widespread adoption of work from home, have all contributed to an increase in attacks, which have increased 314% in the first half of this year compared the first half of 2022. Rather worryingly, between the first and second quarter this year, there was a 387% increase in activity.

Ransomware Attacks Hit Record Levels in UK as More Companies Fail to Tackle Growing Threats

A report from the Information Commissioner’s Office (ICO) in the UK found ransomware attacks on UK organisations reached record levels last year, impacting over 700 organisations. This isn’t the true count though, as it does not factor the overwhelming majority of victims who do not report attacks, so the true number will be many times this. This increase comes as reports are finding that UK companies are struggling to address the growing threats, and this includes a lack of understanding at the Board level. In fact, 59% of directors say their Board is not very effective in understanding the drivers and impacts of cyber risks for their organisation.

Microsoft Warns of More Attacks as Ransomware Spreads Through Teams Phishing

Microsoft says an initial access broker known for working with ransomware groups has recently switched to Microsoft Teams phishing attacks to breach corporate networks. Referring to one of the groups, Microsoft said “In July 2023, Storm-0324 began using phishing lures sent over Teams with malicious links leading to a malicious SharePoint-hosted file,". This tactic has also been used by Russian Nation State Actors.

Europol - Financial Crime Makes “Billions” and Impacts “Millions”

The European policing alliance’s first ever European Financial and Economic Crime Threat Assessment was compiled from “operational insights and strategic intelligence” contributed by member states and Europol partners. The assessment highlighted a criminal economy worth billions of euros and that impacts millions of victims each year.

Almost One in Three Parents Have Never Spoken to Their Children About Cyber Security

A recent report found that 30% of parents have never spoken to their children about cyber security. Additionally, over 40% of parents, who themselves admitted that they didn’t know how to create strong passwords, still give their child access to their mobile phones and almost a third (32%) give them access to their computers. By doing so, parents are not only putting their children at risk, but inadvertently, themselves and the organisations they work for as well.

Hackers are Dropping USB Drives Outside Buildings to Target Networks

A mid-year cyber security report found that along with the explosive growth in AI, bad actors are still using tried and tested, but unfortunately still very effective, tactics such as dropping USB drives outside target buildings in the hope that an employee will pick them up and plug them into devices connected to the corporate network. Many times, these actors are banking on their targets lacking protections against these attacks. Think about your organisation, would someone plug a device they found in the street into their work computer out of curiosity? Does your organisation have controls in place to prevent this type of attack?

Data Theft is Now the No. 1 Cyber Security Threat Keeping Execs Awake at Night

According to a recent survey, 55% of IT decision-makers cited data theft as their main concern, with ransomware placed third, after phishing. This comes as ransomware attackers are moving towards more exfiltration-based techniques. Exfiltration creates a significant number of issues for an organisation including the regulatory requirements of telling customers, to not knowing what data has been exfiltrated.

If You Didn’t Change Your Passwords After the LastPass Data Breach, Do It Now

Criminals have had plenty of time to use encryption keys stolen in the 2022 LastPass hack to open vaults, and there has been a reported increase in the number of vaults that have been cracked. For those attackers that haven’t been able to crack your password, they're under no time constraints.

Whilst successful attackers may not directly target your email accounts, PayPal wallets, or banks, these assets can be packaged and sold to other criminal third parties. If any of the passwords stored in a LastPass vault prior to 2022 are still in use, you should change them immediately.

Cloud Vulnerabilities Surge Nearly 200% as Cloud Credentials Become the New Hot Ticket on the Dark Web

IBM tracked 632 new cloud-related vulnerabilities (CVEs) between June 2022 and June 2023, a 194% increase from the previous year, according to a new report. The latest haul of new CVEs brings the total number tracked by the vendor to 3,900; a number that has doubled since 2019. Similarly, a separate report from Palo Alto Networks found that 80% of security exposures exist in the cloud.

IBM highlighted that this has led to a number of cloud credentials being actively sold on the dark web, in some cases for the same price as a dozen doughnuts. These credentials are believed to account for almost 90% of goods and services for sale on the dark web.
