Threat actor analysis

Kraken has disclosed 25 victims on its leak site, 0.1% of all ransomware listings tracked in this database. Its earliest disclosure here dates to February 2025.

The group has listed organisations in 10 countries, most often in United States (8 victims), followed by Canada, Spain, Germany.

By industry, its listings concentrate in Technology, Business Services, Transportation/Logistics — sectors that hold sensitive data or cannot tolerate long outages, both of which raise the pressure to pay.

Like most current ransomware operations, Kraken is likely to use double extortion: data is stolen before files are encrypted, and organisations that refuse to pay are named on the leak site with the stolen data as leverage.
