GigaWiper is a sophisticated Golang-based backdoor discovered by Microsoft Threat Intelligence in October 2025 that amalgamates at least three previously separate malware families — a standalone disk wiper, Crucio ransomware, and FlockWiper — into a single modular implant with 20 commands. It uses RabbitMQ and Redis for C2 communication, establishes persistence via scheduled tasks, and offers capabilities including disk wiping, fake ransomware (with unrecoverable encryption), BSOD induction, screen recording, keylogging, registry management, event log clearing, and VNC-like remote control. The malware masquerades as legitimate Windows components (OneDrive Update, CloudExperienceHost) and uses AES-encrypted configurations with hard-coded credentials.
