Disclosure context

About direwolf

Direwolf is a ransomware group that emerged in May 2025 with primarily financial motivations, having targeted 71 known victims across multiple sectors and geographic regions. The group's origin and potential affiliations remain undocumented in public threat intelligence reports, with no confirmed information regarding whether they operate as a Ransomware-as-a-Service model or as an independent entity. Their attack methodology and technical capabilities have not been extensively documented by major cybersecurity firms or government agencies, though their targeting patterns indicate a focus on manufacturing, technology, healthcare, and transportation/logistics sectors across Malaysia, the United States, Thailand, Singapore, and Taiwan. No major high-profile campaigns or significant ransomware demands have been publicly attributed to this group by CISA, FBI, or established security researchers such as Mandiant. Given the group's recent emergence and limited public documentation, their current operational status and long-term threat posture remain unclear, requiring continued monitoring by the cybersecurity community to establish a more comprehensive threat profile. The group has been linked to 75 public disclosures across our corpus. First observed on a leak site on May 27, 2025; most recent post June 12, 2026. The operation is currently active.

If your organisation is affected

A listing by direwolf means Guan Chong Berhad 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 direwolf'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.
