BlackSuit: A Hybrid Approach with Data Exfiltration and Encryption

**Executive summary:** This Cybereason Threat Analysis documents a multi-stage BlackSuit ransomware operation that leveraged Cobalt Strike for C2 and lateral movement, renamed rclone for exfiltration (~60 GB observed), and a BlackSuit payload that deleted shadow copies and encrypted files while dropping ransom notes; the report provides IOCs (hashes, IPs, domains), MITRE ATT&CK mappings, and remediation recommendations.
