About the group
kraken posted its first listing on Feb 9, 2025 and has listed 25 organizations to date.
Kraken is a Russian-speaking ransomware group that emerged in February 2025, believed to have links to the HelloKitty operation, employing a RaaS model notable for a benchmarking step that measures victim machine speed to optimize encryption, and in September 2025 launched an underground criminal forum called "The Last Haven Board."

What does this listing mean?
Ransomware groups move data out of the organization before encrypting systems and threaten to publish it if the ransom is not paid. This method is called double extortion.
The listing shows that the group claims to have targeted the organization. Whether the data was published is shown by the later status of the listing.
What should you do if your organization is listed on a leak site?
- Record the listing and any published sample files; do not visit the leak site from the corporate network.
- Isolate affected systems and preserve logs without deleting them.
- Determine which data left the organization; if personal data is involved, review notification obligations with your legal team.
- Make any decision about the ransom demand together with legal, management and incident response.
- Do not bring systems back online before the attacker’s entry point is closed.
