Cybersecurity researchers have warned about a Windows version of a wiper malware that was previously observed targeting Linux systems in cyber attacks aimed at Israel.

Dubbed BiBi-Windows Wiper by BlackBerry, the wiper is the Windows counterpart of BiBi-Linux Wiper, which has been put to use by a pro-Hamas hacktivist group in the wake of the Israel-Hamas war last month.

"The Windows variant confirms that the threat actors who created the wiper are continuing to build out the malware, and indicates an expansion of the attack to target end user machines and application servers," the Canadian company said Friday.

Slovak cybersecurity firm is tracking the actor behind the wiper under the name BiBiGun, noting that the Windows variant is designed to overwrite data in the C:Users directory recursively with junk data and appends.

Sys extensions, the wiper deletes shadow copies from the system, effectively preventing the victims from recovering their files.

It's not immediately clear if the wiper has been deployed in real-world attacks, and if so, who the targets are.
