Kairos is a ransomware/data-extortion operation that publishes victims on a dedicated leak site; this dashboard has tracked 8 victim posts since monitoring began on 2026-06-14, most recently on 2026-09-02. Posting volume is low and steady (8 in 90 days, 3 in 30 days), consistent with a small operation rather than a high-volume affiliate network. Observed victims are concentrated in local and municipal government, with an education institution and small-to-mid-sized manufacturing and services firms also represented. The group's origin, ransomware lineage, affiliate model, initial-access techniques, and financial activity are not documented in widely available public reporting and are treated as unknown here. Not to be confused with the similarly named 2016 Kairos ransomware family distributed via exploit kits.

Tactics & tooling
  • Maintains a public leak site listing victims, consistent with a data-theft extortion model
  • Low posting cadence (~8 victims in ~3 months) rather than mass listing
  • Targets local/municipal government entities (city, commune, and ayuntamiento administrations)
  • Operates against victims in multiple countries (Belgium, France, Spain, Canada, and the US observed on the leak site)
  • Initial-access techniques, tooling, and exploited vulnerabilities publicly reported: unknown
Targeted sectors
Government (local/municipal)EducationManufacturingBusiness services
Notable public victims

Ville de Libercourt, Ayuntamiento de Velilla de San Antonio, Ayuntamiento de Valdemoro, Commune de Camiers, College O'Sullivan de Quebec, Warwick Fabrics, Thermalex Inc, Hightech Signs, LR Reed, McCarthy Inc
