The Gentlemen is a ransomware and data-extortion group that posts victim names on a public leak site and threatens to publish stolen data. In a burst of activity, this dashboard recorded 24 claimed victims between 2026-09-04 and 2026-09-09, spanning healthcare, aviation, retail, construction, manufacturing, and travel across North America, South America, Europe, and Asia. Recent press coverage links the group to attacks on electronic health records vendor Veradigm and hospital operator Nutex Health, in which patient data was reported stolen and threatened for release. Public reporting on the group's origins, affiliate model, and initial access techniques is limited, and no specific CVEs are widely attributed to it. Whether it is a newly emerged operation or a rebrand of an existing gang is unknown.

Tactics & tooling
  • Runs a public leak site naming victims and threatening to publish stolen data
  • Double extortion: data theft paired with leak threats; patient data cited in reported healthcare incidents
  • Described in press coverage as a ransomware gang; encryption behavior not publicly documented
  • High-velocity victim claiming: 24 posts within roughly one week (this dashboard, 2026)
  • Broad multi-region, multi-sector targeting, including healthcare organizations holding patient/EHR data
  • Initial access vector, tooling, and affiliate model: unknown
