killsec3
ransomware group · aka KillSec, KillSec3, KillSec 3 · unknown · active since Mid-2023 (per public ransomware leak-site trackers)
KillSec (tracked here under the leak-site designation 'killsec3') is an opportunistic ransomware and data-extortion operation first observed by ransomware trackers in mid-2023; any relationship to a similarly named hacktivist collective is unconfirmed. The group publishes victims and stolen data on a Tor leak site with publication countdowns, consistent with a double-extortion model, but in-depth vendor research into its malware payload, affiliate structure, and ransom demands is limited. Its listings show broad, opportunistic targeting of predominantly small and mid-sized organizations across healthcare, veterinary, legal, insurance, manufacturing, and consumer services in the United States, Latin America, India, and Israel. This dashboard's tracking shows low recent volume — 3 victims in the past 90 days and 3 total since 2026-07-23 — in line with the group's generally low posting cadence. No specific CVEs are publicly associated with its tradecraft, and no public earnings estimates are available.
- Publishes victim announcements and stolen data on a Tor leak site with countdown timers to publication
- Claims double extortion (data theft plus encryption); public detail on the encryption payload used is limited
- Targets small and mid-sized organizations more than large enterprises, based on listed victims
- Opportunistic, multi-region targeting with no clear geographic pattern (US, Mexico, Brazil, India, Israel observed)
- Multi-sector targeting: healthcare, veterinary, legal, insurance, manufacturing, consumer services
- Initial access vectors not publicly documented; no widely reported exploitation of specific CVEs
- Uses leak-site publication deadlines as the primary extortion lever in posted cases
