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 71 public disclosures across our corpus. First observed on a leak site on May 27, 2025; most recent post January 13, 2026. The operation is currently active.

Attack summary

Severity: medium — Data is marked as published, suggesting some level of exfiltration or disclosure has occurred, but no specific data types, volume, or proof files are described in the leak post, preventing a higher severity classification. Coral's scale and consumer-facing nature (potential PII exposure) warrants at least medium severity.

The direwolf ransomware group claims to have attacked Coral, with the disclosure status indicating data has been published; however, the leak post provides no specific details about encryption, exfiltration volume, or the nature of data stolen.
