Dire Wolf is a ransomware and data-extortion group first publicly reported in March 2025, operating a Tor-based leak site and using a double-extortion model of data theft plus encryption. Vendor research (notably Broadcom/Symantec in 2025) documented rapid intrusions against small and mid-sized organizations across multiple regions, with attackers using bring-your-own-vulnerable-driver (BYOVD) techniques to disable EDR and living-off-the-land tooling for discovery and staging. Attribution and the initial-access vector remain publicly unknown, and no specific CVEs have been tied to the group in available vendor reporting. This dashboard tracked 11 newly listed victims between 2026-09-04 and 2026-09-09, spanning technology, healthcare, logistics, and financial services.

Tactics & tooling
  • Deploys Windows ransomware combined with data theft; posts stolen data to a Tor leak site when demands are unmet (vendor and leak-site reporting, 2025)
  • Uses BYOVD abuse of vulnerable signed drivers to terminate or blind EDR agents (Symantec/Broadcom, 2025)
  • Living-off-the-land binaries and native Windows tools for reconnaissance and staging (vendor reporting, 2025)
  • Targets primarily small and mid-sized organizations across multiple industries and regions (vendor reporting, 2025)
  • Ransom notes instruct victims to contact the group for negotiation; published details of the payment channel are limited (unknown)
  • Initial access vector not publicly confirmed (unknown)
