clop
ransomware group · aka Clop, Cl0p, TA505, FIN11 (related tracking, Mandiant), Lace Tempest (Microsoft) · Russia (widely assessed as Russian-speaking; exact attribution unknown) · active since 2019 (Clop ransomware); precursor TA505/FIN11 activity tracked since 2016
Clop (Cl0p) is a Russian-speaking data-extortion group long associated with the TA505 and FIN11 actor designations, known for high-volume extortion built on data theft rather than file encryption. The group is best known for mass exploitation of managed file transfer products: Accellion FTA (2020-21), SolarWinds Serv-U (2021), Fortra GoAnywhere (2023), Progress MOVEit (2023), Cleo (2024), and Oracle E-Business Suite (2025), affecting thousands of organizations. Its playbook combines SQL injection and webshell exploitation for initial access, large-scale exfiltration, leak-site listings, and mass email extortion campaigns aimed at victims' customers and partners. Public impact tallies (Emsisoft, 2023) counted 2,700+ organizations affected in the MOVEit campaign, but a confirmed aggregate earnings figure has not been published. Leak-site tracking on this dashboard shows continued activity, with 2 posts in the past 7 days (HENRYPRATT.COM, HARLEY-DAVIDSON.COM) as of 2026-09-10.
