Grief

Family profile

Grief is a ransomware operation described in the provided content as having ties to the Russian cybercrime group Evil Corp and as an offshoot of DoppelPaymer, which itself evolved from Evil Corp. The group conducts double-extortion activity by stealing data and threatening to leak additional files unless an undisclosed ransom is paid. In the cited NRA incident, Grief posted the victim on its leak site, claimed to possess 13 files allegedly taken from NRA databases, and exposed material that reportedly included recent board meeting minutes, grant-related documents, and tax forms. The content also notes reporting that messaging around the NRA breach was amplified by a network of fake Twitter accounts, although public attribution did not establish that the network belonged to Grief. The group is reported to have spent much of 2021 targeting U.S. school districts and local governments, with additional attacks against government, healthcare, and education entities in states including New York, Alabama, Mississippi, Indiana, Washington, and Texas. Because of its reported Evil Corp lineage, ransom payments associated with Grief may carry U.S. sanctions risk. High-confidence behaviors directly mentioned in the content include operation of a public leak site, extortion through threatened publication of stolen data, and targeting of U.S. organizations including the National Rifle Association.
