Disclosure context

About werewolves

The Werewolves ransomware group is a relatively new financially-motivated cybercriminal organization that emerged in December 2023, with limited public documentation available from major threat intelligence sources. Based on available targeting data, the group appears to operate with a focus on business services and manufacturing sectors, having compromised 26 known victims across multiple countries including Russia, the United States, Netherlands, Germany, and France. The group's targeting pattern suggests they may employ opportunistic attack vectors rather than highly sophisticated initial access methods, though specific technical details about their encryption methods, data exfiltration practices, or operational structure remain undocumented by major security research organizations. Due to the group's recent emergence and relatively small victim count, there are no publicly reported high-profile campaigns or significant law enforcement actions against them. The current operational status of Werewolves remains unclear given the limited threat intelligence reporting available from established cybersecurity firms and government agencies. The group has been linked to 26 public disclosures across our corpus. First observed on a leak site on December 20, 2023; most recent post March 13, 2024. The operation is currently inactive.

If your organisation is affected

A listing by werewolves means auditexpertnn.ru appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Monitor for the data appearing on werewolves's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
