Cybercriminals are increasingly targeting penetration testers to join ransomware affiliate programs such as Apos, Lynx, and Rabbit Hole, according to Cato Network's Q3 2024 SASE Threat Report, published by its Cyber Threats Research Lab (CTRL).

The report highlights numerous Russian-language job advertisements uncovered through surveillance of discussions on the Russian Anonymous Marketplace (RAMP). Speaking at an event in Stuttgart, Germany, on November 12, Etay Maor, Chief Security Strategist at Cato Networks, explained:"Penetration testing is a term from the security side of things when we try to reach our own systems to see if there are any holes. Now, ransomware gangs are hiring people with the same level of expertise - not to secure systems, but to target systems."

He further noted, "There's a whole economy in the criminal underground just behind this area of ransomware."

The report details how ransomware operators aim to ensure the effectiveness of their attacks by recruiting skilled developers and testers. Maor emphasized the evolution of ransomware-as-a-service (RaaS), stating, "[Ransomware-as-a-service] is constantly evolving. I think they're going into much more details than before, especially in some of their recruitment."

Cato Networks' team discovered instances of ransomware tools being sold, such as locker source code priced at $45,000. Maor remarked:"The bar keeps going down in terms of how much it takes to be a criminal. In the past, cybercriminals may have needed to know how to program. Then in the early 2000s, you could buy viruses. Now you don't need to even buy them because [other cybercriminals] will do this for you."

AI's role in facilitating cybercrime was also noted as a factor lowering barriers to entry. The report flagged examples like a user under the name ‘eloncrypto’ offering a MAKOP ransomware builder, an offshoot of PHOBOS ransomware.

The report warns of the growing threat posed by Shadow AI—where organizations or employees use AI tools without proper governance. Of the AI applications monitored, Bodygram, Craiyon, Otter.ai, Writesonic, and Character.AI were among those flagged for security risks, primarily data privacy concerns.

Cato CTRL also identified critical gaps in Transport Layer Security (TLS) inspection. Only 45% of surveyed organizations utilized TLS inspection, and just 3% inspected all relevant sessions. This lapse allows attackers to leverage encrypted TLS traffic to evade detection.

In Q3 2024, Cato CTRL noted that 60% of CVE exploit attempts were blocked within TLS traffic. Prominent vulnerabilities targeted included Log4j, SolarWinds, and ConnectWise.

The report is based on the analysis of 1.46 trillion network flows across over 2,500 global customers between July and September 2024. It underscores the evolving tactics of ransomware gangs and the growing challenges organizations face in safeguarding their systems.
