In April, Industroyer2 was used towards industrial management methods (ICS).
As Russia intensified its actions in our on-line world, the assaults continued and Ukraine’s largest cell community operator, Kyivstar, had its IT infrastructure partially destroyed in a December 2023 cyberattack.
Now, Talos says a vital infrastructure entity inside Ukraine fell sufferer to a damaging assault through which new malware, dubbed PathWiper, was used.

The shopper then executed the command as a batch (BAT) file, with the command line partially resembling that of Impacket command executions, although such instructions don’t essentially point out the presence of Impacket in an setting,” Talos explains.Commercial.

When executed, PathWiper tried to dismount volumes and to switch the contents of file system artifacts with random information, utilizing one thread per drive and quantity for every recognized path. Focused artifacts embody MBR, $MFT, $MFTMirr, $LogFile, $Boot, $Bitmap, $TxfLog, $Tops, and $AttrDef.
Among the 2022 wiper assaults towards Ukraine had been attributed to Cadet Blizzard, an APT working on behalf of GRU. Final 12 months, the US introduced prices towards a member of the group.
