Ransomware Evolution and Data Exfiltration: A Deep Dive for Cybersecurity Analysts 

The document surveys the rise and business impact of ransomware and the shift to double/triple extortion, outlines frequently abused dual-use tools for data exfiltration (e.g., Rclone, AnyDesk/ScreenConnect/Atera, Cobalt Strike, WinRAR/7‑Zip, Restic, Chisel), and maps top MITRE ATT&CK techniques across initial access, defense evasion, exfiltration, and impact. It highlights sector-specific risks (notably Manufacturing, Transportation, Education, Healthcare) and prescribes defenses including hardening remote access, controlling dual-use tools, resilient and tested backups, and outbound/exfiltration monitoring. The piece concludes with a prevention-first pitch for Morphisec’s AMTD/AEM-based exfiltration protection.
