Sandworm, also known as APT44, Voodoo Bear, and Seashell Blizzard, is a highly aggressive Russian state-sponsored cyber-espionage and sabotage unit. Publicly attributed to the Main Directorate of the General Staff of the Armed Forces of the Russian Federation (GRU), specifically Unit 74455, the group is widely considered the most dangerous threat actor currently active.[1]
While many APT groups focus on data theft, Sandworm is distinguished by its mandate to conduct destructive operations. The group is responsible for the first recorded cyber-induced power outages in history and the release of the NotPetya malware, which caused over $10 billion in global damages.[2]

Overview
Sandworm has been active since at least 2009. Unlike the GRU’s APT28, which focuses on intelligence and influence, Sandworm functions as a “kinetic” cyber unit, often timing its attacks to coincide with military movements or political pressure.[1]
Attribution
In 2020, the U.S. Department of Justice indicted six officers of GRU Unit 74455 for their roles in Sandworm operations.[3] Forensic links between the 2015/2016 Ukraine power grid attacks and the 2017 NotPetya outbreak have led to a “High” confidence attribution.
Targets and victimology
- Energy Grids — Electrical substations and distribution management systems.
