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

94% of Ransomware Victims Have Their Backups Targeted by Attackers

Organisations that have backed up sensitive data may believe they are safe from the effects of ransomware attacks; however a new study by Sophos reported that cyber criminals attempted to compromise the backups of 94% of companies hit by ransomware in the past year. The research found that criminals can demand a higher ransom when they compromise an organisation’s backup data, and those victims are twice as likely to pay. The median ransom demand is $2.3 million when backups are compromised, compared to $1 million otherwise.

Additionally, sectors like state and local governments, along with media and entertainment, are particularly vulnerable with nearly all affected organisations experiencing backup compromises.

Sharing IT Providers Is a Risk for Financial Services, Says IMF, as Rising Cyber Threats Pose Serious Concerns for Financial Stability

The International Monetary Fund has found that with greater digitalisation and heightened geopolitical tensions comes a greater risk of cyber attack with systemic consequences. The IMF noted that losses more than quadrupled since 2017 to $2.5 billion.

The push for technology has led to a number of financial services institutions relying on third-party IT firms, increasing their susceptibility to cyber disruption on a wider scale and a potential ripple effect were a third party to be hit. Whilst such third parties can increase the cyber resilience of a financial services institution, they also expose the industry to systemwide shocks, the IMF reports.

The IMF recommend institutions should identify potential systematic risks in their third-party IT firms. If the organisation is unable to perform such risk assessments, they should seek the expert support of an independent cyber security specialist.

Hackers are Threatening to Publish a Huge Stolen Sanctions and Financial Crimes Watchlist

A cyber crime group named GhostR has claimed responsibility for stealing 5.3 million records from the World-Check database, which companies use for "know your customer" (KYC) checks to screen potential clients for financial crime risks. The data theft occurred in March and originated from a Singapore-based firm with access to World-Check. The London Stock Exchange Group (LSEG), which owns World-Check, confirmed that the breach involved a third-party's dataset and not their systems directly. The stolen data includes sensitive information on individuals identified as high-risk, such as government-sanctioned figures and those linked to organised crime. LSEG is coordinating with the affected third party and authorities to protect the compromised data and prevent its dissemination.

Your Annual Cyber Security Is Not Working, But There is a Solution

Most organisations utilise annual security training in an attempt to ensure every department develops their cyber awareness skills and is able to spot and report a threat. However, this training is often out of date. Additionally, often training has limited interactivity, failing to capture and maintain employees’ attention and retention. On top of this, many training courses fail to connect employees to real-world scenarios that could occur in their specific job.

To get the most return on investment, organisations need to have more regular education, with the aim of long-term behavioural shifts in the work place, nudging employees towards greater cyber hygiene.

73% of Security Professionals Say They’ve Missed, Ignored or Failed to Act on a High Priority Security Alert

A new survey from Coro, targeting small medium enterprises (SME) cyber security professionals, reveals that 73% have missed or ignored high priority security alerts due to overwhelming workloads and managing multiple security tools. The 2024 SME Security Workload Impact Report highlights that SMEs are inundated with alerts and responsibilities, which dilute their focus from critical security threats. On average, these professionals manage over 11 security tools and spend nearly five hours daily on tasks like monitoring and patching vulnerabilities. Respondents handle an average of over 2,000 endpoint security agents across 656 devices, more than half dealing with frequent vendor updates.

Russia and Ukraine Top Inaugural World Cyber Crime Index

The inaugural World Cybercrime Index (WCI) identifies Russia, Ukraine, and China as the top sources of global cyber crime. This index, the first of its kind, was developed over four years by an international team from the University of Oxford and the University of New South Wales, with input from 92 cyber crime experts. These experts ranked countries based on the impact, professionalism, and technical skills of their cyber criminals across five cyber crime categories, including data theft, scams, and money laundering. Russia topped the list, followed by Ukraine and China, highlighting their significant roles in high-tech cyber criminal activities. The index, expected to be updated regularly, aims to provide a clearer understanding of cyber crime's global geography and its correlation with national characteristics like internet penetration and GDP. Of note the UK and US also made the top ten list, so it is not just other countries we need to worry about.

Top ten Countries in full:

1.       Russia

2.       Ukraine

3.       China

4.       United States

5.       Nigeria

6.       Romania

7.       North Korea

Police Takedown Major Cyber Fraud Superstore: Will the Cyber Crime Industry Become More Fragmented?

The London Metropolitan Police takedown of online fraud service LabHost serves as a reminder of the industrial scale on which cyber crimes are being performed, with the service amassing 480,000 debit or credit card numbers and 64,000 PINs: all for the subscription price of £300 a month. The site even included tutorial videos on how to commit crime and offered customer service.

Such takedowns can lead to fragmentation. The 2,000 individuals subscribed to LabHost may have lost access but where there is demand, supply will be found. The takedown of one service allows other, small services to fill the gap. As the saying goes ‘nature abhors a vacuum’ and it is especially true when it comes to cyber crime; there is too much business for empty spaces not to be filled.

Small Businesses See Stable Business Climate; Cite Cyber Security as Top Threat

Small businesses are experiencing a stable business climate, as reflected by the Small Business Index, indicating an increasing optimism about the economy. However, the recent surge in cyber attacks, including major assaults on UnitedHealth Group and MGM Resorts, has underscored the growing vulnerability of these businesses to cyber crime. Despite 80% of small to medium-sized enterprises feeling well-protected by their IT defences, a Devolutions survey reveals that 69% of them still fell victim to cyber attacks last year. This has led to cyber security being viewed as the greatest threat by 60% of small businesses, even surpassing concerns over supply chain disruptions and the potential for another pandemic.

The average cost of these attacks ranges from $120,000 to $1.24 million, leading to 60% of affected businesses closing within six months. This vulnerability is further compounded by a common underestimation of the ransomware threat. While 71% of businesses feel prepared for future threats, the depth of this preparedness varies, with only 23% feeling very prepared for cyber security challenges.

The Threat from Inside: Insider Threats Surge 14% Annually as Cost-of-Living Crisis Bites

Employee fraud grew significantly last year thanks to the opportunities afforded by remote working and the pressures of a cost-of-living crisis in the UK, according to Cifas, an anti-fraud non-profit. The number of individuals recorded in its cross-sector Insider Threat Database (ITD) increased 14% year-on-year (YoY) in 2023, with the most common reason being “dishonest action to obtain benefit by theft or deception” (49%).

Insider threats – both by accident or with malicious intent – by their own employees are overlooked, despite accounting for 58% of cybersecurity breaches in recent years. As a result, a large proportion of businesses may lack any strategy to address insider risks, leaving them vulnerable to financial, operational and reputational harm.

Dark Web Sales Driving Major Rise in Credential Attacks as Attackers Pummel Networks with Millions of Login Attempts

Dark web sales are driving a major rise in credential attacks, with a surge in infostealer malware attacks over the last three years significantly heightening the cyber crime landscape. Kaspersky reports a sevenfold increase in data theft attacks, leading to the compromise of over 26 million devices since 2022. Cyber criminals stole roughly 400 million login credentials last year alone, often sold on dark web markets for as low as $10 per log file. These stolen credentials have become a lucrative commodity, fostering a complex economy of initial access brokers who facilitate broader corporate network infiltrations. The Asia-Pacific and Latin America regions have been particularly affected, with millions of credentials stolen annually.

Simultaneously, Cisco’s Talos team warns of a current credential compromise campaign targeting networks via mass login attempts to VPN, SSH, and web apps. Attackers use a mix of generic and specific usernames with nearly 100 passwords from about 4,000 IP addresses, likely routed through anonymising services (such as TOR). These attacks pose risks like unauthorised access, account lockouts, and potential denial-of-service. The attack volume has increased since 18 March this year mirroring a previous alert by Cisco about a similar campaign affecting VPNs. Despite method and infrastructure similarities, a direct link between these campaigns is yet to be confirmed.

Large Enterprises Experience Breaches, Despite Large Security Stacks; Report Finds 93% of Breaches Lead to Downtime and Data Loss

93% of enterprises admitting to having had a breach have suffered significant consequences, ranging from unplanned downtime to data exposure or financial loss, according to a recent report. 73% of organisations made changes to their IT environment at least quarterly, however only 40% tested their security at the same frequency. Unfortunately, this means that many organisations are facing a significant gap in which changes in the IT environment are untested, and therefore their risk unknown.

Security tools can aid this, however as the report finds, despite having a large number of security stacks, 51% still reported a breach in the past 24 months. Organisations must keep in mind that security extends beyond the technical realm, and it needs to include people and operations.

Charities Doing Worse than Private Sector in Staving off Cyber Attacks

Recent UK Government data reveals a significant cyber security challenge for charities, with about a third experiencing breaches this past year, equating to nearly 924,000 cyber crimes. Notably, 83% of these incidents involved phishing, with other prevalent threats including fraud emails and malware. The data found that 63% of charities said cyber security was a high priority for senior management, however, charities lag behind the private sector in adopting security monitoring tools and conducting risk assessments.

Additionally, while half of the charities implement basic cyber hygiene defences like malware protection and password policies, only about 40% seek external cyber security guidance.

Cyber Weekly Flash Briefing 18 Sept 2020: Higher cyber losses; old MS Office exploit; banking Trojan given away free; new Bluetooth flaw; IoT risks; DDoS attacks up; US charge Iranians & Russians

Cyber Weekly Flash Briefing 18 September 2020: Cyber losses increasing in frequency & severity, decade-old MS Office exploit, Cerberus banking Trojan released for free to attackers, Bluetooth vulnerability affects billions of devices, The Internet of Things devices that could put you at risk from hackers

Links to articles are for interest and awareness and linking to or reposting external content does not endorse any service or product, likewise we are not responsible for the security of external links.

Cyber losses are increasing in frequency and severity

Research by a cyber insurance provider in North America shows cyber attacks have increased in number and severity since the onset of the coronavirus pandemic. The changes that organisations implemented to facilitate remote work have given cyber criminals new opportunities to launch campaigns exploiting mass uncertainty and fear.

The severity of ransomware attacks has increased since the beginning of COVID-19, with researchers having observed a 47% increase on top of a 100% increase in Q1 2020.

Researchers also found that newer strains of ransomware have been particularly malicious, with costly ransom demands and criminal actors threatening to expose an organisation’s data if they don’t pay. They report that the average demand from attackers using the Maze variety of ransomware is approximately six times larger than the overall average.

Researchers also reported a 35% increase in funds transfer fraud and social engineering claims filed by their policyholders since the pandemic began. Reported losses from these types of attack have ranged from the low thousands to well above $1 million per event.

Additionally, COVID-19 has resulted in a notable surge of business email compromise. The insurer observed a 67% increase in the number of email attacks during the pandemic.

Why this matters:

The report refers to North America but the findings are applicable to us all. They indicate that the most frequent types of losses incurred by victims were from ransomware (41%), funds transfer loss (27%), and business email compromise incidents (19%) — accounting for 87% of reported incidents and 84% of the insurer’s claim pay-outs in the first half of 2020.

Clearly with the landscape getting worse, firms more likely to fall victim, and with losses increasing all the time, firms should ensure they are taking these threats seriously.

Hackers have revived a decade-old Microsoft Office exploit - and they’re having a field day

Hackers have ramped up attempts to abuse a decade-old Microsoft Office flaw with the help of creative new email scams, new research has found.

According to analysis commissioned by NordVPN, attempts to exploit the vulnerability (CVE-2017-11882) rose by 400% in the second quarter of the year - with further growth expected.

Why this matters:

If exploited successfully, the memory corruption bug could allow attackers to execute code on the target device remotely. This is especially problematic if the affected user’s account has administrative privileges, in which case the hacker could seize control of the system.

Cerberus banking Trojan source code released for free to cyber attackers

The source code of the Cerberus banking Trojan has been released as free malware on underground hacking forums following a failed auction.

The leaked code, distributed under the name Cerberus v2, presents an increased threat for smartphone users and the banking sector at large. 

Why this matters:

Cerberus is a mobile banking Trojan designed for the Google Android operating system. In circulation since at least July 2019, the Remote Access Trojan (RAT) is able to conduct covert surveillance, intercept communication, tamper with device functionality, and steal data including banking credentials by creating overlays on existing banking, retail, and social networking apps.

The malware is able to read text messages that may contain one-time passcodes (OTP) and two-factor authentication (2FA) codes, thereby bypassing typical 2FA account protections. OTPs generated through Google Authenticator may also be stolen.

Critical Bluetooth security vulnerability could affect billions of devices worldwide

A new security flaw in the Bluetooth software stack discovered over the summer has the potential to affect billions of smartphones, laptops and IoT devices using the Bluetooth Low Energy (BLE) protocol.

The new vulnerability has been given the name BLESA (Bluetooth Low Energy Spoofing Attack) by the team of seven academic researchers at Purdue University who first discovered it.

Unlike the recently discovered BLURtooth vulnerability that deals with how Bluetooth devices pair with one another, BLESA was found in the reconnection process. Reconnections occur when two BLE devices move out of range and then move back into range. Normally BLE devices check the cryptographic keys negotiated during the pairing process when reconnecting.

The research team found that the official BLE specification did not contain strong-enough language to describe the reconnection process properly leading to two systemic issues making their way into BLE software implementations.

The first deals with the fact that authentication during device reconnection is optional as opposed to mandatory while the second relates to how authentication can potentially be circumvented if a user's BLE device fails to force another device to authenticate the cryptographic keys sent while reconnecting.

Why this matters:

Billions of devices could be vulnerable to these BLESA attacks where a nearby attacker bypasses reconnection verification and sends spoofed data to a BLE device with incorrect information. This can lead both humans and automated processes to make incorrect decisions when it comes to allowing two devices to reconnect with one another.

Coffee machines, cuddly toys and cars: The Internet of Things devices that could put you at risk from hackers

Connected teddy bears, connected coffee machines and connected cars are just some of the unusual Internet of Things (IoT) devices being insecurely connected to corporate networks that could leave whole organisations open to cyber attacks.

A research paper by Palo Alto Networks details the surge in IoT devices being connected to corporate networks and their wide variety.

Some of the most common irregular devices being connected to organisations' networks include connected vehicles, connected toys and connected medical devices, with connected sports equipment such as fitness trackers, gaming devices and connected cars also being deployed.

These devices are being connected because they can often help people through the working day or help manage aspects of their personal life, but they're also creating additional problems for the corporate network.

Why this matters:

In many cases, these 'shadow IoT' devices are being added to the network without the knowledge of the security team.

This could potentially leave the corporate network vulnerable because not only do some IoT devices have poor security that means they can easily be discovered and exploited, but some workplaces still have flat networks and if a device is compromised then an attacker can move from the IoT product to another system.

DDoS Attacks Skyrocket as Pandemic Bites

More people being online during lockdowns and more people working from home has proven to be lucrative for DDoS type attacks.

The first half of 2020 saw a significant uptick in the number of distributed denial-of-service (DDoS) attacks compared to the same period last year — a phenomenon that appears to be directly correlated to the global coronavirus pandemic.

One firm’s Security Operations Centre (SOC) saw a 151 percent increase in DDoS activity in the period, including one of the largest and longest attacks they had has ever mitigated – that attack came in at 1.17 terabits-per-second (Tbps), and lasted five days and 18 hours.

These figures are representative of the growing number, volume and intensity of network-type cyber attacks as organizations shifted to remote operations and workers’ reliance on the internet increased.

Why this matters:

DDoS attacks are getting bigger, with a “noticeable spike” in volume: The number of attacks sized 100Gbps and above grew a whopping 275 percent. Emblematic of this is a 2.3Tbps attack targeting an Amazon Web Services client in February – the largest volumetric DDoS attack on record. And the aforementioned 1.17Tbps attack was 192 percent bigger than the largest attack mitigated during the first half of 2019.

US charges two Russians for stealing $16.8m via cryptocurrency phishing sites

The US Department of Justice has filed charges this week against two Russian nationals for orchestrating a multi-year phishing operation against the users of three cryptocurrency exchanges.

The two suspects stand accused of creating website clones for the Poloniex, Binance, and Gemini cryptocurrency exchanges, luring users on these fake sites, and collecting their account credentials. These phishing operations began around June 2017.

US officials said the Russian duo — made up of Danil Potekhin (aka cronuswar) and Dmitrii Karasavidi; residents of Voronezh and Moscow, respectively — used the stolen credentials to access victim accounts and steal their Bitcoin (BTC) and Ether (ETH) crypto-assets.

Why this matters:

In total, US officials estimated the victims in the hundreds. Court documents cite 313 defrauded Poloniex users, 142 Binance victims, and 42 users at Gemini. Losses were estimated at $16,876,000.

Whilst bitcoin has waned in popularity after its highs a few years back there is still value in holdings held in different exchanges and these holdings remain popular targets for attackers.

US charges two Iranian hackers for years-long cyber-espionage, cybercrime spree

The US has also filed charges against and is seeking the arrest of two Iranian nationals believed to have carried out cyber-intrusions at the behest of the Iranian government and for their own personal financial gain.

In an indictment unsealed this week, prosecutors accused Hooman Heidarian and Mehdi Farhadi, both from Hamedan, Iran, of launching cyber-attacks against a wide range of targets since at least 2013.

Past victims included several US and foreign universities, a Washington think tank, a defense contractor, an aerospace company, a foreign policy organization, non-governmental organizations (NGOs), non-profits, and foreign government and other entities the defendants identified as rivals or adversaries to Iran, with most targets located in the US, Israel, and Saudi Arabia.

US officials said Heidarian and Farhadi focused on gaining access to their victims' accounts, computers, and internal networks, from where they stole confidential data and communications pertaining to topics such as national security, foreign policy, nuclear energy, and aerospace.

Why this matters:

Financial data and personally identifiable information wasn't off-limits, and the two also stole intellectual property, such as unpublished scientific research.

In addition, the two also targeted and stole personal information and communications of Iranian dissidents, human rights activists, and opposition leaders, according to George M. Crouch Jr., Special Agent in Charge of the FBI Newark Division.

Prosecutors believe that some of the stolen data was handed over to Iranian government intelligence officials, but that other information was also sold on black markets for the hackers' personal gains.

Alert issued to UK universities and colleges about spike in cyber attacks

British universities and colleges have been warned about a spike in ransomware attacks targeting the education sector by the UK's National Cyber Security Centre (NCSC), a part of GCHQ.

Academic institutions are being urged to follow NCSC guidance following a sharp increase in attacks which have left some teachers fearing they won't be able to accept students when term begins.

Last week staff at Newcastle University warned Sky News they had "no idea how we are going to welcome students in three weeks' time" following one such ransomware attack, which has impacted IT services across the whole university.

Similar attacks in which criminal hackers infiltrated computer networks and stole data before encrypting the machines and demanding a ransom payment to unlock them again, have hit Northumbria University, Bolton Sixth Form College, Leeds City College and others in August alone.

Speaking to Sky News, NCSC's director of operations Paul Chichester said the agency had seen an increase in the "utterly reprehensible" attacks over the past 18 months and was concerned they would disrupt young people's education.

Why this matters:

There are more than a dozen criminal groups which are currently earning millions by encrypting their victim's computer networks and then leaking stolen documents online to pressure the victims into paying up.
