EvilCorp, a sanctioned Russian cybercriminal group, has been linked to RansomHub, a rapidly growing ransomware-as-a-service operation. The collaboration between these entities raises concerns about potential sanctions for RansomHub, as their combined tactics involve using malware like SocGholish to infiltrate systems and execute ransomware attacks. This connection could complicate the landscape for organizations responding to ransomware incidents and increase scrutiny from law enforcement.

Cybercriminals are utilizing malicious traffic distribution systems (TDS), such as TAG-124, to deliver targeted malware and conduct ransomware attacks on high-value targets, particularly in the healthcare sector. This infrastructure enhances the efficiency of cybercriminal operations, enabling them to exploit vulnerabilities and maximize extortion payouts. Understanding and mitigating the risks associated with TAG-124 is crucial for organizations to defend against these sophisticated attacks.

An international law enforcement operation has successfully taken down AVCheck, a counter antivirus service used by cybercriminals to test malware evasion against commercial antivirus software. The takedown is part of Operation Endgame, which aims to disrupt organized cybercrime by targeting services that help criminals refine their malware for maximum effectiveness. Evidence links AVCheck's administrators to other crypting services that further support cybercriminal activities.
