This new Windows malware can take over your PC and wipe it clean

GigaWiper, a modular Windows backdoor, has been observed by Microsoft in intrusions since October 2025, combining robust remote access capabilities with multiple methods for permanently destroying systems and data¹. This malware is notable for its operational platform approach, blending command-and-control, data destruction, and remote access options into a single piece of malware. GigaWiper's architecture suggests it was built using previously separate tools, such as the Crucio ransomware and FlockWipe. The malware's ability to take control of a PC and wipe it clean poses a significant threat to Windows users. Its modular design and combination of features make it a formidable tool for attackers. The presence of GigaWiper highlights the importance of operational resilience planning, particularly in sectors that rely heavily on Microsoft products, so practitioners must prioritize robust security measures to mitigate the risk of such attacks.
