McAfee ATR Threat Report: A Quick Primer on Cuba Ransomware

Cuba ransomware has evolved into an active Ransomware-as-a-Service campaign that combines file encryption with data exfiltration and a public leak site; actors use obfuscated PowerShell scripts for lateral movement, leverage/common pentest tools and frameworks (e.g., winPEAS, Bloodhound, Cobalt Strike), and target financial, industry, technology, and logistics organizations. The report provides YARA rules, IOCs, MITRE ATT&CK mappings and defensive guidance such as monitoring for dual‑use tool abuse, hardening RDP and credentials, patching public‑facing apps, and strengthening endpoint protection.
