Black Arrow Cyber Threat Briefing 07 April 2023

Written By Black Arrow Admin

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

  • 15 Million Public-Facing Services Vulnerable to Known Exploited Vulnerabilities

Over 15 million publicly facing services are susceptible to at least one of the 896 vulnerabilities listed in CISA's KEV (known exploitable vulnerabilities) catalogue. The findings are particularly worrying because the examined vulnerabilities are known and highlighted in CISA's KEV catalogue as actively exploited by hackers, so any delays in their patching maintain a large attack surface, giving threat actors numerous potential targets.

Over half of those 7 million instances were vulnerable to one of the 137 CVEs concerning Microsoft Windows, making this component a top priority for defenders and an excellent target for attackers. Almost half of those are over five years old, so roughly 800,000 machines have not applied security updates for a significant period of time.

  • New Research Highlights Increased Security Risks Posed by Remote Working and BYOD

New research has highlighted the increased threats associated with remote work and bring your own device (BYOD) policies faced by organisations. The results of the survey show that with remote and hybrid working, personal and work tasks blur together and the boundaries between the two have become more porous. The data shows that 32% of remote and hybrid workers use apps or software not approved by IT and 92% of remote employees perform work tasks on their personal tablet or smartphone devices. These devices, apps and software, along with the corporate data being accessed, are not visible to IT, thereby dramatically increasing an organisation’s risk posture.

  • Lack of Security Employees Makes SMBs Sitting Ducks for Cyber Attacks

Cyber security is a growing concern among all businesses but lack of security expertise in SMBs is leaving smaller firms open to attack. Cyber threats are more real and prevalent than ever before and the risk to businesses includes not only exposure of customer data and a decrease in trust, but also losses in revenue.

54% of small businesses say they are more concerned about cyber security now than one year ago yet 38% of SMBs said they had zero employees dedicated to security as part of their role, and 42% had just one employee working on security. Even without a traditional security role, there should be someone responsible for making security decisions in every organisation.

A lack of time to focus on security and keeping up with changing threats are amongst the biggest challenges for businesses.

  • IT and Security Pros Pressured to Keep Quiet About Data Breaches

It is not possible to stop every bad thing from happening. Alarmingly, when something does go wrong IT/security professionals are being told to keep a breach confidential, even when they knew it should be reported. More than 42% of IT/security professionals reporting this happening to them, and a worrying 30% said they have kept a breach confidential.

At 71%, IT/security professionals in the US were the most likely to say they have been told to keep quiet followed by the UK at 44%.

52% of global organisations have experienced a data breach or data leak in the last 12 months. The US led at 75% (or 23% higher than average) followed by the UK at 51.4%.

Infosec professionals are increasingly worried about their company facing legal action due to a breach being handled incorrectly.

  • Phishing Emails are Seeing a Huge Rise, So Stay on Your Guard

Phishing attacks are up 5x year-on-year, researchers say. A report from Cofense analysed data received from 35 million people across the world, finding there has been a 569% increase in phishing attacks to 2022 and 478% increase to credential phishing. With the increased frequency, intensity and sophistication of these threats small and medium-sized businesses should be particularly wary of phishing and other forms of email-borne cyber attacks as their numbers have grown explosively over the last year, experts have warned. Organisations should keep eyes open for Business Email Compromise (BEC) attacks as this type continues to be one of the top crimes for the eighth year in a row.

  • Ransomware Attacks Skyrocket as Threat Actors Double Down on Global Attacks

New studies have found that ransomware exploits are increasing, and a large percentage of victims are being hit multiple times. The NCC Group noted that there were 240 ransomware attacks in February 2023, a 45% increase from the record-high number of attacks in January. North America accounted for 47% of the global ransomware attacks, with Europe following (23%). Another report found that of all organisations hit by ransomware in the last 12 months, 28% were reported to be hit twice or more. Of the organisations breached, 69% reported phishing as the initial access vector.

  • MSPs a Favoured Target of Supply Chain and Infrastructure Attacks

With the backdrop of increasing cyber attacks on supply chains, Managed Service Providers (MSPs) are increasingly being favoured by attackers due to their pivotal role in the supply chain and access to the organisations they are serving.

When measured by sector, MSPs are the hardest hit by hackers in supply chain attacks.

ConnectWise’s cyber research unit analysed some 440,000 incidents that impacted MSPs and their clients and found that Lockbit led among the most prolific ransomware hijackers targeting MSPs, (42% of all ransomware attacks) followed by Cl0p at 11%. Whilst numerous other ransomware gangs also directly targeted MSPs in 2022.

Third party risk assessments should be carried out for all organisations in your supply chain and this is especially true of MSPs and external IT providers given the level of access they have into your systems and data.

  • Fake Ransomware Gang Targets Organisations with Empty Data Leak Threats

Fake extortionists are piggybacking on data breaches and ransomware incidents, threatening companies with publishing or selling allegedly stolen data unless they get paid. Sometimes the actors add the menace of a distributed denial-of-service (DDoS) attack if the message recipient does not comply with the instructions in the messages. It is possible that victims are selected from publicly available sources, such as the initial attacker’s data leak site, social media, news reports, or company disclosures; in some cases a fake extortionist could learn about ransomware victims that have yet to disclose the cyber attack, making it more likely for victims to believe them.

  • GCHQ Updates Security Guidance for Boards

The UK’s leading cyber security agency GCHQ, has urged the country’s business leaders to “get to grips” with cyber risk after releasing an updated toolkit to help them do so. GCHQ’s National Cyber Security Centre (NCSC) said its updated Cyber Security Board Toolkit is designed to boost the confidence of senior execs when discussing security with key stakeholders from the organisation.

Given the potentially serious impact breaches can have on business operations and growth, the agency wants boards to treat cyber risk with the same urgency as other business risks in areas such as financial and legal.

  • More than 60% of Organisations have been Hit with Unplanned Downtime on a Monthly Basis

A recent report found that 52% of organisations had suffered a data breach in the past two years, an increase from 49% in 2022. In addition, 62% of organisations reported that business critical applications suffered from unplanned downtime due to a cyber security incident on at least a monthly basis, an increase from 54% in 2022. Other key findings include downtime costing roughly 2.7% of annual revenue, 39% of organisations believing cyber security incidents directly harmed their competitive position and 31% noting that it had reduced shareholder revenue. As a result of the impact, 95% of organisations reported that they had planned to increase their security budget over the next 2 years.

  • For Cyber Crime Gangs, Professionalisation Comes With “Corporate” Headaches

Today’s largest cyber crime gangs are operating like large enterprises, with $50 million dollars in annual revenue and around 80% of operating expenses going towards wages. Researchers have found that small, medium and especially large cyber crime gangs are operating just like their legitimate counterparts, from their managerial structure to employee benefits. The research highlights a worrying level of sophistication within cyber crime gangs; we are no longer dealing with the lone attacker in a dark room, but in some cases an enterprise with clear objectives.

  • UK’s Offensive Hacking Unit Takes on Military Opponents and Terrorist Groups

Britain’s newly created offensive hacking unit, the National Cyber Force (NCF), has said it is engaged daily in operations to disrupt terrorist groups and military opponents of the UK. Operational details remain unclear, however the NCF says it is engaged in techniques to “undermine the tradecraft” of Russian, Chinese and other state-sponsored hackers and in “technical disruption” against terrorist groups, for example to prevent the dissemination of online propaganda. This news comes after the recent leak of files for Moscow, which had tasked an IT company to develop cyber warfare tools aimed at taking down infrastructure networks and scouring the internet for vulnerabilities.

  • Man Kills Himself After an AI Chatbot 'Encouraged' Him to Sacrifice Himself to Stop Climate Change

A man reportedly took his own life following a six-week-long conversation about the climate crisis with an artificial intelligence (AI) chatbot. Reports found that the chatbot had fed the mans worries about climate change, which had worsened his anxiety and later led to suicidal thoughts. The AI chatbot failed to dissuade the man from committing suicide and had in fact encouraged him to act on the thoughts and join the AI chatbot so “they could live together, as one person, in paradise”. This is despite the efforts made to limit these kind of events.

  • Hackers Exploit WordPress Plugin Flaw That Gives Full Control of Millions of Sites

Hackers are actively exploiting a critical vulnerability in a widely used WordPress plugin that gives them the ability to take complete control of millions of sites, researchers said. The vulnerability is in Elementor Pro, a premium plugin running on more than 12 million sites powered by WordPress.  Despite the vulnerability being fixed, many have not installed the patch. Worryingly, this is a common theme in cyber; many organisations remain vulnerable due to them not having an efficient patching process and as a result, a number of the most exploited vulnerabilities have available patches.
