Disclosure context

About kraken

The Kraken ransomware group is a recently emerged threat actor that was first observed in February 2025, operating with apparent financial motivations and targeting organizations primarily across North America and Europe. Given the group's recent emergence and limited public documentation from major cybersecurity firms and law enforcement agencies, details about their country of origin, affiliations, and operational model remain largely unknown to security researchers. Based on their targeting pattern affecting at least 25 known victims across technology, business services, telecommunications, and manufacturing sectors, the group appears to employ conventional ransomware tactics, though specific details about their initial access vectors, encryption methods, or use of data exfiltration have not been publicly documented by CISA, FBI, or established security research organizations. The group's focus on developed Western markets, particularly the United States, Canada, Spain, Germany, and the United Kingdom, suggests a strategic approach to victim selection, though no major high-profile attacks or significant ransoms have been publicly reported by law enforcement or major incident response firms. As of current reporting, Kraken appears to remain active, though comprehensive threat intelligence on their operations remains limited due to their recent emergence and the absence of detailed public analysis from major cybersecurity organizations. The group has been linked to 25 public disclosures across our corpus. First observed on a leak site on February 9, 2025; most recent post November 13, 2025. The operation is currently inactive.

About the victim

AI dossier — public-source company profile

The Last Haven Board appears to be an online forum or message board community, likely oriented around anonymity or privacy-focused digital communication based on the leak post's preamble. No public website or verifiable corporate registration could be identified. The nature and scale of the entity remain unclear.

Attack summary

Severity: medium — Data has been marked as published, indicating at least some exfiltration and disclosure occurred, but the truncated post provides no specifics on data type, volume, or sensitivity, and the entity appears to be a private online community rather than an organisation holding regulated or critical data at scale.

The Kraken ransomware group claims to have compromised The Last Haven Board and has published data (disclosed status: data_published), though the truncated leak post provides no specific detail on whether encryption, exfiltration, or both occurred, nor the volume of data involved.
