New GigaWiper Windows Backdoor Bundles Disk Wiping, Fake Ransomware, and Spyware
New GigaWiper backdoor combines disk wiping, fake ransomware, and spyware for destructive attacks.
Microsoft has identified a new destructive Windows backdoor named GigaWiper, which consolidates three older destructive tools: a disk wiper, a fake ransomware module, and a drive wiper. This malware, also known as BLUERABBIT, is suspected to be linked to an Iran-nexus group targeting Israeli organizations. Beyond its destructive capabilities, GigaWiper also functions as spyware, collecting sensitive data and providing remote access.

The lesson from this incident
Full lessonThe GigaWiper (BLUERABBIT) backdoor represents a sophisticated convergence of destructive capabilities — disk wiping, fake ransomware, and spyware — likely deployed by an Iran-nexus threat actor targeting Israeli organizations. By bundling multiple attack vectors into a single payload, attackers can simultaneously destroy data, deceive incident responders into treating the incident as ransomware, and exfiltrate sensitive information before destruction. This multi-stage approach significantly complicates forensic investigation and delays effective incident response. The use of fake ransomware as a decoy is particularly dangerous because it misdirects recovery efforts toward negotiation rather than containment and restoration. Organizations without robust backups and endpoint detection may face unrecoverable data loss.
What helps against this
How we list vendors- Endpoint detection and response (EDR and XDR)
Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.
- Network detection and response (NDR)
Attackers moving between systems inside the network get seen.
- Immutable backup and recovery
Ransomware cannot delete or encrypt your way back.
