AWS Data Exfiltration and Attempted Ransomware

In February 2025, a UK-based AWS environment was infiltrated using compromised VPN credentials. The threat actor conducted internal reconnaissance with Nmap and staged data exfiltration using the Rclone tool, transferring sensitive files from AWS file servers, particularly finance and investment data, to external VPS endpoints. Lateral movement was attempted via RDP, with further data staging and outbound SSH connections to known malicious IPs.
