**Cuba Ransomware Crisis** — The report describes the Cuba ransomware gang's operations, detailing an incident where an entertainment company had files encrypted with a ".cuba" extension and sensitive data (including PII and source code) exfiltrated; attackers demanded a multi-million (8-digit USD) ransom payable in BTC. Mitiga's investigation attributes Living-off-the-Land TTPs, likely phishing or 1-day RCE vectors, a suspected Russian linkage based on C2 evidence, and documents mitigation steps discovered during incident response.
