The group is also the author of the NotPetya ransomware that hit hundreds of companies worldwide in June 2017.
Once executed, the wiper deletes shadow copies, recursively overwrites files. The wiper targets files located in %CSIDL_SYSTEM%drivers, %CSIDL_SYSTEM_DRIVE%WindowsNTDS and other non-system drives before rebooting the infected system. The SwiftSlicer wiper overwriting files with 4096 bytes length blocks with randomly generated byte.
On September 2022, the Sandworm group was observed impersonating telecommunication providers to target Ukrainian entities with malware.
Security firms warn that the Sandworm APT continues to target Ukraine with multiple means, including custom malware and botnet.
