ORCSHRED is a Linux worm associated with Sandworm, the Russian military intelligence threat group linked to GRU Unit 74455. It was deployed during the April 2022 operation against a Ukrainian energy provider that combined Industroyer2 with destructive malware intended to disrupt electricity delivery and hinder recovery. ORCSHRED forms the propagation component of a destructive toolset that also includes the Linux and Solaris wipers AWFULSHRED and SOLOSHRED. Although frequently grouped with those wipers, ORCSHRED is specifically identified as the Linux worm component. The campaign also deployed CaddyWiper against Windows systems. The initial access mechanism for the energy-provider compromise has not been established.
