Ransomware: A Primer
There have been discussions about whether or not ransomware activity is on the decline, including by our own experts here at Consortium Networks, spurred by geopolitical activity and law enforcement actions, the fact is that Q1 of 2023 has seen a 27% increase in ransomware data leaks over Q1 2022 (672 vs 855). This issue is not only growing in terms of frequency, but speed as well. In the past, we saw operators spend months studying a system and the organization whereas recently there have been instances of organizations’ data being encrypted within a matter of days from initial infiltration. According to the numbers, Ransomware is still a huge problem.
Ransomware actors regularly innovate their TTPs but at a high-level ransomware attacks typically follow a core set of patterns: initial access, lateral movement, execution, exfiltration, encryption, user notification, and extortion. In some cases DDoS has also been applied against victims and in others, threat actors moved directly to extortion bypassing the encryption step.
Some of the more effective means of combating ransomware have been backing up data in a secure environment that cannot be encrypted by the threat actors, and using legitimate services that have developed ways of decrypting many of the strains of ransomware.
However, neither of these methods deal with the significant potential damages resulting from sensitive data being leaked on publicly open ransomware extortion sites. The leaks can cause loss of intellectual property, competitive advantage, insider information, personally identifiable information (PII), personal health information (PHI), lead to various lawsuits, etc.
Thus, while it is very important to have a plan for dealing with a ransomware event, it is still preferable to try to prevent the event in the first place. In order to do so, it is vital to understand how the threat actors may gain access to victim systems and networks.
Companies Face New SEC Regulations
Many companies are now grappling with the imminent enforcement of the new SEC regulations. According to Davis Polk, this affects specifically “market entities” including “many types of broker-dealers, clearing agencies, major security-based swap participants, the Municipal Securities Rulemaking Board, national securities associations, national securities exchanges, security-based swap data repositories, security-based swap dealers, and transfer agents.” A rule proposed by the SEC last year would make a company obligated to report a cybersecurity breach within 4 days of noticing it. This rule, which changes the game on incident reporting, is now up for comments with the comment period ending on May 22nd.
Sifting Through the Hype: Insider Threat, ChatGPT and Cybersecurity
ChatGPT and generative AI have become an inescapable part of the cybersecurity conversation since January, dominating everything from individual conversations to the massive RSA conference in late April. Fears abound about how generative AI could revolutionize cybercrime and radically change the cybersecurity landscape.
Some fears are well-founded, particularly those that popped up following Samsung’s source code being accidentally leaked by an employee to ChatGPT. However, this is no new issue, and source code has been leaked by accident well before ChatGPT came onto the scene. The greater issue here is one that has been around much longer and is much less flashy than emerging technology and that is strong, comprehensive, and understandable cybersecurity policies.

UK Warns Russian Hacktivists Targeting Western Critical Infrastructure: The British National Cyber Security Centre (NCSC) warned that pro-Russian hacktivists known for their fairly harmless digital defacement campaigns have plans to move to more destructive attacks on Western organizations. NCSC assesses that the hacktivists currently are unlikely to have the necessary skills to do real-world damage on critical infrastructure systems, they may soon be the recipients of “external assistance,” especially after demonstrating the ability to infiltrate Canadian gas infrastructure as discovered in March’s trove of leaked intelligence documents.
Annual OpIsrael Attacks Hit Israeli Critical Water Infrastructure: Several water monitors that are part of Israeli irrigation and wastewater treatment systems were left non-functional following a cyberattack at the beginning of April. This attack was part of the broader annual OpIsrael campaign in which anti-Israeli hackers attack Israeli networks throughout Ramadan. The irrigation system impacted by this attack is one of the most sophisticated and sought-after water management systems in the world and has been a part of many conversations in getting countries to the negotiating table for the Abraham Accords, making this target high-value both because of its importance as critical infrastructure and as a political statement. Other victims include Israeli media agencies, medical websites, government websites, and university websites.

EDR Software Increasingly Vulnerable: As hacking defense systems get better, hackers get craftier, experts say as they see EDR systems increasingly being successfully targeted.
New Class of Russian Hackers: A new league of Russian hackers have emerged in the last 18 months and they, unlike some of the other big players in the arena at the moment, seem ideologically motivated rather than financially motivated. These players seem more inclined to cause harm than just conducting DDoS or other nuisance attacks. NCSC has suggested significantly upping your cyber security game if you think you might be targeted.
Chinese Government Opens Investigation into Micron: Micron, a US memory chip vendor, is being investigated by the Chinese government as a potential national security risk. These accusations closely mirror those the US made about Huawei, a Chinese telecom equipment vendor. Trade restrictions around the world are trying to block the Chinese semiconductor business. The Micron accusations are likely retaliation for the United States’s hand in this and/or the conveniently timed accusations against Huawei.
Sophos Warns of Increased Attacks: Almost 94% of companies were victims of a cyber attack within the last year.
