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.

Tactics & tooling
  • Mass exploitation of internet-facing managed file transfer software (MOVEit, GoAnywhere, Accellion FTA, Serv-U, Cleo, Oracle EBS)
  • Exfiltration-first extortion: data theft without encryption; victims published on the Cl0p leak site
  • SQL injection and webshell deployment in file-transfer intrusions (e.g., MOVEit human2.aspx webshell)
  • Mass email extortion campaigns sent to victims' customers and partners to amplify pressure
  • Historic spearphishing with macro-enabled Office documents for initial access (TA505-era)
  • Use of rclone for bulk exfiltration reported in some file-transfer campaigns
  • Ransomware deployment (Clop) in some intrusions, though major campaigns since 2023 are largely encryption-free
  • Public deadlines on leak-site listings to pressure negotiations
