ExfilSquad
ExfilSquad is an emerging data-extortion group that surfaced on July 26, 2026, operating a Tor-hosted Data Leak Site to publicly claim data theft from 15 organizations, including Microsoft. Their model focuses on public exposure and pressure tactics without confirmed encryption, lacking evidence of a Ransomware-as-a-Service structure or specific initial-access methods. The group has not provided forensic evidence or verifiable data samples, raising questions about the credibility of their claims, which may involve reused or fabricated data.
