The BiBi-Windows Wiper artifact is claimed to have been compiled on Oct 21, 2023, two weeks following the onset of the war. The precise process by which it is dispersed is presently unfamiliar.
In addition to corrupting all information with the exception of these with .exe, .dll, and .sys extensions, the wiper deletes shadow copies from the process, efficiently preventing the victims from recovering their data files.
