Redazione RHC 26/06/2025

Do you remember the infamous REvil cyber gang? The Russian hacker group responsible for some of the most devastating ransomware attacks in the early days of this global threat, known for posting their criminal exploits on the popular underground forum “Happy Blog”. The Dzerzhinsky Court in St. Petersburg has convicted four more participants in the REvil (aka Sodinokibi) hacking group case, according to media reports.

Redazione RHC 24/06/2025

According to a report by Cato Networks, cybercriminals continue to actively use LLM patterns in their attacks. Specifically, we are talking about versions of theGrok and Mixtral patterns that have been deliberately modified to bypass built-in restrictions and generate malicious content. Apparently, one such modified version of Grok appeared on the popular forum BreachForums in February 2025. It was posted by a user with the pseudonym Keanu. The tool is a wrapper around the original Grok model and is controlled via a specially written system prompt. This is how the authors ensure that the model bypasses protection mechanisms and generates phishing emails, malicious code, and hacking instructions. A

Redazione RHC 23/06/2025

In mid-May 2025, Cloudflare blocked the largest DDoS attack ever recorded: 7.3 terabits per second (Tbps). This event comes shortly after the release of the DDoS Threat Report for Q1 2025 on April 27, 2025, which highlighted attacks reaching 6.5 Tbps and 4.8 billion packets per second (pps). 37.4 terabytes isn’t a huge number by today’s standards, but downloading 37.4 terabytes in just 45 seconds is. That’s the equivalent of flooding the internet with over 9,350 HD movies or streaming 7,480 hours of uninterrupted high-definition video (nearly a year’s worth of back-to-back TV binge-watching) in just 45 seconds. If it were music,
