Top Cyber Stories of the Last Week

  • 50% of UK CEOs see Cyber as a Bigger Business Risk than the Economy

Half of UK CEOs consider cyber security as a bigger risk to their organisation than economic uncertainty, a new study by Palo Alto Networks has found. The findings came from a survey of 2500 CEOs from the UK, Germany, France, Brazil and the UAE at large organisations (500+ employees).

Despite the recognition of the business threats posed by cyber attacks, UK CEOs have a lower level of understanding of cyber security risks than their international counterparts, with just 16% saying they have a complete understanding. This compares to 21% in Brazil, 21% in the UAE, 22% in France and 39% in Germany. Additionally, many UK CEOs feel detached from responsibility for cyber security at their organisations, instead leaving it to the responsibility of IT, although IT is only part of the solution.

  • Report Finds 78% of Organisations Felt Prepared for Ransomware Attacks, Yet Half Still Fell Victim

Fortinet has unveiled its 2023 Global Ransomware Report based on a recent global survey and explores cyber security leaders’ perspectives on ransomware, particularly how it impacted their organisations in the last year and their strategies to mitigate an attack. The report found that the global threat of ransomware remains at peak levels, with half of organisations across all sizes, regions and industries falling victim in the last year.

The top challenges to stopping a ransomware attack were people and process related, with many organisations lacking clarity on how to secure against the threat. Specifically, four out of the five top challenges to stopping ransomware were people or process related. The second largest challenge was a lack of clarity on how to secure against the threat as a result of a lack of user awareness and training and no clear chain-of-command strategy to deal with attacks.

Despite the global macroeconomic environment, security budgets will have to increase in the next year with a focus on AI/ML technologies to speed detection, centralised monitoring tools to speed response and better preparation of people and processes.

  • SMBs and Regional MSPs are Increasingly Targeted by State-Sponsored APT Groups

Advanced persistent threat (APT) attacks were once mainly a concern for large corporations in industries that presented cyber espionage interest. That's no longer the case and over the past year in particular, the number of such state-sponsored attacks against small- and medium-sized businesses (SMBs) has increased significantly.

Cyber security firm Proofpoint analysed its telemetry data more than 200,000 SMB customers over the past year and saw a rise in phishing campaigns originating from APT groups, particularly those serving Russian, Iranian, and North Korean interests.

SMBs are also targeted by APT groups indirectly, through the managed services providers (MSPs) that maintain their infrastructure. Proofpoint has seen an increase in attacks against regional MSPs because their cyber security defences could be weaker than larger MSPs yet they still serve hundreds of SMBs in local geographies.

  • IT Employee Piggybacked on Cyber Attack for Personal Gain

A 28-year-old former IT employee of an Oxford-based company has been convicted of blackmailing his employer and unauthorised access to a computer with intent to commit other offences.

The convicted employee was the one who began to investigate the incident and, along with colleagues and the police, tried to mitigate it and its fallout. But he also realized that he could take advantage of the breach to line his own pockets.

“He accessed a board member’s private emails over 300 times as well as altering the original blackmail email and changing the payment address provided by the original attacker. This was in the hope that if payment was made, it would be made to him rather than the original attacker,” the South East Regional Organised Crime Unit (SEROCU) revealed. He went as far as creating an almost identical email address to that of the original attacker, using it to pressure his employer into making the payment.

While some insider threats may stem from negligence or ignorance, this case highlights a more sinister scenario involving a malicious, opportunistic individual. Malicious insiders exploit their authorized access and privileges to engage in harmful, unethical, or illegal activities.

  • Ransomware Threats Are Growing, and Targeting Microsoft Devices More and More

Ransomware attacks have never been this popular, a new report from cyber security researchers Securin, Ivanti, and Cyware has stated. New ransomware groups are emerging constantly, and new vulnerabilities being exploited are being discovered almost daily, but out of all the different hardware and software, Microsoft’s products are being targeted the most.

Attackers are now targeting more than 7,000 products built by 121 vendors, all used by businesses in their day-to-day operations. Most products belong to Microsoft, which has 135 vulnerabilities associated with ransomware. In just March 2023, there had been more breaches reported, than in all three previous years combined. Even though most cyber security incidents never get reported, too. In the first quarter of the year, the researchers discovered 12 new vulnerabilities used in ransomware attacks, three-quarters of which (73%) were trending in the dark web.

  • Microsoft Reports Jump in Business Email Compromise (BEC) Activity

Thirty-five million business email compromise (BEC) attempts were detected in the last year, according to the latest Microsoft Cyber Signals report. Activity around BEC spiked between April 2022 and April 2023, with over 150,000 daily attempts, on average, detected by Microsoft’s Digital Crimes Unit.

Rather than targeting unpatched devices for vulnerabilities, BEC operators focus on leveraging the vast volume of daily email and other message traffic to trick victims into sharing financial information or unknowingly transferring funds to money mule accounts. Their goal is to exploit the constant flow of communication to carry out fraudulent money transfers.

Using secure email applications, securing identities to block lateral movement, adopting a secure payment platform and training employees are a few effective methods, according to the report.

  • Forrester Predicts 2023’s Top Cyber security Threats: From Generative AI to Geopolitical Tensions

The nature of cyber attacks is changing fast. Generative AI, cloud complexity and geopolitical tensions are among the latest weapons and facilitators in attackers’ arsenals. Three-quarters (74%) of security decision-makers say their organisations’ sensitive data was “potentially compromised or breached in the past 12 months” alone. Forrester’s Top Cyber security Threats in 2023 report provides a stark warning about the top cyber security threats this year, along with prescriptive advice to CISOs and their teams on countering them. By weaponising generative AI and using ChatGPT, attackers are fine-tuning their ransomware and social engineering techniques.

Perimeter-based legacy systems not designed with an AI-based upgrade path are the most vulnerable. With a new wave of cyber attacks coming that seek to capitalise on any given business’ weakest links, including complex cloud configurations, the gap between reported and actual breaches will grow.

Forrester cites Russia’s invasion of Ukraine and its relentless cyber attacks on Ukrainian infrastructure as examples of geopolitical cyber attacks with immediate global implications. Forrester advises that nation-state actors continue to use cyber attacks on private companies for geopolitical purposes like espionage, negotiation leverage, resource control and intellectual property theft to gain technological superiority.

  • Advanced Phishing Attacks Surge 356% in 2022

A new report published this week observed a 356% growth in the number of advanced phishing attacks attempted by threat actors in 2022, with the total number of attacks having increased by 87%. Among the reasons behind this growth is the fact that malicious actors continue to gain widespread access to new tools, including artificial intelligence (AI) and machine learning (ML)-powered tools. These have automated the process of generating sophisticated attacks, including those characterized by social engineering as well as evasion techniques.

The global threat landscape continues to evolve with a meteoric rise in the number of attacks, combined with increasingly sophisticated attack techniques designed to breach and damage organisations.

Additionally, the report highlighted that the changing threat landscape has resulted from the swift adoption of new cloud collaboration apps, cloud storage and productivity services for external collaboration.

  • Today’s Cyber Defence Challenges: Complexity and a False Sense of Security

Organisations can mistakenly believe that deploying more security solutions will result in greater protection against threats. However, the truth of the matter can be very different. Gartner estimates that global spending on IT security and risk management solutions will exceed $189.7 billion annually in 2023, yet the breaches keep on coming. Blindly purchasing more security tools can add to complexity in enterprise environments and creates a false sense of security that contributes to today’s cyber security challenges.

To add to the dilemma, the new work-from-anywhere model is putting a strain on IT and security teams. Employees shifting between corporate and off-corporate networks are creating visibility and control challenges, which are impacting those teams’ ability to diagnose and remediate end user issues and minimize cyber security risks. In addition, they have to deal with a broad mix of networks, hardware, business and security applications, operating system (OS) versions, and patches.

  • Almost All Ransomware Attacks Target Backups

Data stored in backups is the most common target for ransomware attackers. Almost all intrusions (93%) target backups and in 75% of cases succeed in taking out victims’ ability to recover. In addition, 85% of global organisations suffered at least one cyber attack in the past year according to the Veeam 2023 Ransomware trends report. Only 16% of organisations avoided paying ransom because they were able to recover from backups, down from 19% in last year’s survey.

According to the survey, criminals attempt to attack backup repositories in almost all (93%) cyber events in EMEA, with 75% losing at least some of their backups and more than one-third (39%) of backup repositories being completely lost.

Other key findings included that 21% said ransomware is now specifically excluded from insurance policies; and of those with cyber insurance, 74% saw increased premiums since their last policy renewal.

With most ransomware actors moving to double and triple extortion the days of a backup being all you need to keep you safe are far behind and firms should do more to prevent being the victim of ransomware in the first place.

  • NCSC Warns Against Chinese Cyber Attacks on Critical Infrastructure

The UK National Cyber Security Centre (NCSC) and several other international security agencies have issued a new advisory warning the public against Chinese cyber activity targeting critical national infrastructure networks. According to the document, the People’s Republic of China (PRC)’s associated threat actors employed sophisticated tactics to evade detection while conducting malicious activities against targets in the US and Guam. These tactics are expected to be used on critical infrastructure targets outside the US, including the UK.

The document further added that the threat actors mainly focused on credential access theft via brute force and password spraying techniques. The NCSC advisory provides network defenders with technical indicators and examples of techniques used by the attacker to help identify any malicious activity.

  • Half of All Companies were Impacted by Spearphishing in 2022

Spearphishing is a sliver of all email exploits but the extent to which it succeeds is revealed in a new study from cyber security firm Barracuda Networks, which analysed 50 billion emails across 3.5 million mailboxes in 2022, unearthing around 30 million spearphishing emails and affecting 50% of all companies.

The report identified the top prevalent spearphishing emails were Scamming (47%) used to trick victims into disclosing sensitive information and the other being brand impersonation (42%) attacks mimicking a brand familiar with the victim to harvest credentials.

The report found that remote work is increasing risks. Users at companies with more than a 50% remote workforce report higher levels of suspicious emails — 12 per day on average, compared to 9 per day for those with less than a 50% remote workforce.

  • Google's .zip, .mov Domains Give Social Engineers a Shiny New Tool

Two new top-level domain names (.zip and .mov) have caused concern among security researchers, who say they allow for the construction of malicious URLs that even tech-savvy users are likely to miss. While a top-level domain (TLD) that mimics a file extension is only one component in the lookalike attack, the overall combination is much more effective with the .zip or .mov extension.

There's no question that phishing links that involve these TLDs can be used to lure unsuspecting users into accidentally downloading malware. Unlike other kinds of phishing URLs that are intended to lure the user to enter credentials into a phony login page, the lures with the .zip or .mov domains are more suited to drive-by download types of attacks.
