Black Arrow Cyber Threat Briefing 21 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

  • March 2023 Broke Ransomware Attack Records with a 91% Increase from the Previous Month

March 2023 was the most prolific month recorded by cyber security analysts in recent years, measuring 459 attacks, an increase of 91% from the previous month and 62% compared to March 2022. According to NCC Group, which compiled the report based on statistics derived from its observations, the reason last month broke all ransomware attack records was CVE-2023-0669. This is a vulnerability in Fortra's GoAnywhere MFT secure file transfer tool that the Clop ransomware gang exploited as a zero-day to steal data from 130 companies within ten days.

Regarding the location of last month's victims, almost half of all attacks (221) breached entities in North America. Europe followed with 126 episodes, and Asia came third with 59 ransomware attacks.

The recorded activity spike in March 2023 highlights the importance of applying security updates as soon as possible, mitigating potentially unknown security gaps like zero days by implementing additional measures and monitoring network traffic and logs for suspicious activity.

  • Organisations Overwhelmed with Cyber Security Alerts, Threats and Attack Surfaces

Many organisations are struggling to manage key security projects while being overwhelmed with volumes of alerts, increasing cyber threats and growing attack surfaces, a new report has said. Compounding that problem is a tendency by an organisation’s top brass to miss hidden risks associated with digital transformation projects and compliance regulations, leading to a false sense of confidence in their awareness of these vulnerabilities.

The study comprised IT professionals from the manufacturing, government, healthcare, financial services, retail and telecommunications industries. Five of the biggest challenges they face include:

  • Keeping up with threat intelligence (70%)

  • Allocating cyber security resources and budget (47%)

  • Visibility into all assets connected to the network (44%)

  • Compliance and regulation (39%)

  • Convergence of IT and OT (32%)

The report also focused on breaches within organisations, finding that 64% had suffered a breach or ransomware attack in the last five years; 43% said it had been caused by employee phishing.

  • One in Three Businesses Faced Cyber Attacks Last Year

Nearly a third of businesses and a quarter of charities have said they were the subject of cyber attacks or breaches last year, new data has shown. Figures collected for the UK Government by polling company Ipsos show a similar proportion of larger and medium-sized companies and high-income charities faced attacks or breaches last year as in 2021.

Overall, 32% of businesses said they had been subject to attacks or breaches over a 12-month period, with 24% of charities saying the same. Meanwhile, about one in ten businesses (11%) and 8% of charities said they had been the victims of cyber crime – which is defined more narrowly – over the 12-month period. This rose to a quarter (26%) of medium-sized businesses, 37% of large businesses and 25% of high-income charities. The UK Government estimated there had been 2.4 million instances of cyber crime against UK businesses, costing an average of £15,300 per victim.

  • Why Your Anti-Fraud, Identity & Cyber Security Efforts Should Be Merged

Across early-stage startups and mature public companies alike, organisations are increasingly moving to a convergence of fraud prevention, identity and access management (IdAM), and cyber security. To improve an organisation's overall security posture, business, IT, and fraud leaders must realise that their areas shouldn't be treated as separate line items. Ultimately, these three disciplines serve the same purpose — protecting the business — and they must converge. This is a simple statement, but complex in practice, due mainly to the array of people, strategies, and tooling that today's organisations have built.

The convergence of these three functions comes at a seminal moment, as global threats are heightened due to several factors: geopolitical tensions like the war on Ukraine, the economic downturn, and a never-ending barrage of sophisticated attacks on businesses and consumers. At the same time, companies are facing slowing revenues, rising inflation, and increased pressure from investors, causing layoffs and budget reductions in the name of optimisation. Cutting back in the wrong areas, however, increases risk.

  • Tight Budgets and Burnout Push Enterprises to Outsource Cyber Security

With cyber security teams struggling to manage the remediation process and monitor for vulnerabilities, organisations are at a higher risk for security breaches, according to cyber security penetration test provider Cobalt. As enterprises prioritise efficiencies, security leaders increasingly turn to third-party vendors to alleviate the pressures of consistent testing and to fill in talent gaps.

Cobalt’s recent report found:

  • Budget cuts and layoffs plague security teams: 63% of US cyber security professionals had their department’s budget cut in 2023.

  • Cyber security professionals deprioritise responsibilities to stay afloat: 79% of US cyber security professionals admit to deprioritising responsibilities leading to a backlog of unaddressed vulnerabilities.

  • Inaccurate security configurations cause vulnerabilities: 40% of US respondents found the most security vulnerabilities were related to server security misconfigurations.

  • Complex 8 Character Passwords Can Be Cracked in as Little as 5 Minutes

Recently, security vendor Hive released their findings on the time it takes to brute force a password in 2023. This year’s study included the emergence of AI tools. The vendor found that a complex 8 character password could be cracked in as little as 5 minutes. This number rose to 226 years when 12 characters were used and 1 million years when 14 characters were used. A complex password involves the use of numbers, upper and lower case letters and symbols.

Last year, the study found the same 8 and 12 character passwords would have taken 39 minutes and 3,000 years, showing the significant drop in the time it takes to brute force a password. The study highlights the importance for organisations to be aware of their password security and the need for consistent review and updates to the policy.

  • 83% of Organisations Paid Up in Ransomware Attacks

A report this week found that 83% of victim organisations paid a ransom at least once. The report found that while entities like the FBI and CISA argue against paying ransoms, many organisations decide to eat the upfront cost of paying a ransom, costing an average of $925,162, rather than enduring the further operational disruption and data loss.

Organisations are giving ransomware attackers leverage over their data by failing to address vulnerabilities created by unpatched software, unmanaged devices and shadow IT. For instance, 77% of IT decision makers argue that outdated cyber security practices have contributed to at least half of security incidents. Over time, these unaddressed vulnerabilities multiply, giving threat actors more potential entry points to exploit and greater leverage to force companies into paying up.

  • Security is a Revenue Booster, Not a Cost Centre

Security has historically been seen as a cost centre, which has led to it being given as little money as possible. Many CISOs, CSOs, and CROs fed into that image by primarily talking in terms of disaster avoidance, such as data breaches hurting the enterprise and ransomware potentially shutting it down. But what if security presented itself instead as a way to boost revenue and increase market share? That could easily shift those financial discussions into something much more comfortable.

For example, Apple touted its investments into the secure enclave to claim that it offers users better privacy. Specifically, the company argued that it couldn't reveal information to federal authorities because the enclave was just that secure. Apple turned that into a powerful competitive argument against rival Android creator Google, which makes much of its revenue by monetising users' data.

In another scenario, bank regulations require financial institutions to reimburse customers who are victimised by fraudsters, but they carve out an exception for wire fraud. Imagine if a bank realises that covering all fraud — even though it is not required to do so — could be a powerful differentiator that would boost its market share by supporting customers better than competitors do.

  • Ex-CEO Gets Prison Sentence for Bad Security

A clinic was recently subject to a cyber attack and even though the clinic was itself the victim, the ex-CEO of the clinic faced criminal charges, too. It would appear that the CEO was aware of the clinic’s failure to employ data security precautions and was aware of this for up to two years before the attack took place.

Worse still, the CEO allegedly knew about the problems because the clinic suffered breaches in 2018 and 2019, and failed to report them; presumably hoping that no traceable cyber crimes would arise as a result, and thus that the company would never get caught out. However, modern breach disclosure and data protection regulations, such as GDPR in Europe, make it clear that data breaches can’t simply be “swept under the carpet” any more, and must be promptly disclosed for the greater good of all.

The former CEO has now been convicted and given a prison sentence, reminding business leaders that merely promising to look after other people’s personal data is not enough. Paying lip service alone to cyber security is insufficient, to the point that you can end up being treated as both a cyber crime victim and a perpetrator at the same time.

  • Warning From UK Cyber Agency for a New ‘Class’ of Russian Hackers

There is a new ‘class’ of Russian hackers, the UK cyber-agency NCSC warns. Due to an increased danger of attacks by state-aligned Russian hackers, the NCSC is encouraging all businesses to put the recommended protection measures into place. The NCSC alert states, “during the past 18 months, a new kind of Russian hacker has developed.” These state-aligned organisations frequently support Russia’s incursion and are driven more by ideology than money. These hacktivist organisations typically concentrate their harmful online activity on launching DDoS (distributed denial of service) assaults against vital infrastructure, including airports, the legislature, and official websites. The NCSC has released a special guide with a list of steps businesses should take when facing serious cyber threats. System patching, access control confirmation, functional defences, logging, and monitoring, reviewing backups, incident plans, and third-party access management are important steps.

  • KnowBe4 Q1 Phishing Report Reveals IT and Online Services Emails Drive Dangerous Attack Trend

KnowBe4 announced the results of its Q1 2023 top-clicked phishing report, and the results included the top email subjects clicked on in phishing tests.

The report found that phishing tactics are changing with the increasing trend of cyber criminals using email subjects related to IT and online services such as password change requirements, Zoom meeting invitations, security alerts and more. These are effective because they would impact an end users’ daily workday and subsequent tasks to be completed.

71% of the most effective phishing lures related to HR (including leave, dress code, expenses, pay and performance) or tax, and these types of emails continue to be very effective.

Emails that are disguised as coming from an internal source such as the IT department or HR are especially dangerous because they appear to come from a more trusted, familiar place where an employee would not necessarily question it or be as sceptical. Building up an organisation’s human firewall by fostering a strong security culture is essential to outsmart bad actors.

  • Outsourcing Group Capita Admits Customer Data May Have Been Breached During Cyber Attack

Capita, which runs crucial services for the UK NHS, Government, Military and Financial Services, has for the first time admitted that hackers accessed potential customer, staff and supplier data during a cyber attack last month. The company said its investigation into the attack – which caused major IT outages for clients – found that hackers infiltrated its systems around 22 March, meaning they had around nine days before Capita “interrupted” the breach on 31 March.

While Capita has admitted that data was breached during the incident, it raises the possibility that public sector information was accessed by hackers. Capita, which employs more than 50,000 people in Britain, is one of the government’s most important suppliers and holds £6.5bn-worth of public sector contracts. Capita stopped short of disclosing how many customers were potentially affected by the breach, and is still notifying anyone whose data might be at risk.

  • Outdated Cyber Security Practices Leave Door Open for Criminals

A recent report found that as organisations increasingly find themselves under attack, they are drowning in cyber security debt – unaddressed security vulnerabilities like unpatched software, unmanaged devices, shadow IT, and insecure network protocols that act as access points for bad actors. The report found a worrying 98% of respondents are running one or more insecure network protocols and 47% had critical devices exposed to the internet. Despite these concerning figures, fewer than one-third said they have immediate plans to address any of the outdated security practices that put their organisations at risk.

  • Quantifying Cyber Risk Vital for Business Survival

Organisations are starting to wake up to the fact that the impact of ransomware and other cyber attacks cause long term issues. The financial implications are far reaching and creating barriers for companies to continue operations after these attacks. As such, quantifying cyber risk is business-specific, and organisations must assess what type of loss they may face, which includes revenue, remediation, legal settlement, or otherwise.

  • Recycled Network Devices Exposing Corporate Secrets

Over half of corporate network devices sold second-hand still contain sensitive company data, according to a new study. The study involved the purchase of recycled routers, finding that 56% contained one or more credentials as well as enough information to identify the previous owner.

Some of the analysed data included customer data, credentials, connection details for applications and authentication keys. In some cases, the data allowed for the location of remote offices and operators, which could be used in subsequent exploitation efforts.

In a number of cases the researchers were able to determine with high confidence — based on the data still present on the devices — who their previous owner was. The list included a multinational tech company and a telecoms firm, both with more than 10,000 employees and over $1 billion in revenue.

The study informed organisations who had owned the routers. Unfortunately, when contacted, some of the organisations failed to respond or acknowledge the findings.
