Threat Actor Analysis

Ailock is a ransomware threat group that has disclosed 51 victims in publicly accessible leak site data, representing 0.2% of all ransomware attacks tracked in this database. The earliest victim disclosure attributed to Ailock in our dataset dates to March 2026.

Geographically, Ailock has targeted organisations in 18 countries. The most frequently targeted nation is United States with 23 victim organisations. Other heavily targeted nations include Japan, United Kingdom, Germany.

Industry-wise, Ailock shows a concentration in the Business Services, Manufacturing, Technology sectors. These industries are frequently targeted because they manage sensitive data, critical operations, or have lower tolerance for operational downtime โ€” conditions that increase ransom payment likelihood.

Like most modern ransomware operations, Ailock likely employs a double extortion model: encrypting victim files while simultaneously exfiltrating data, creating dual pressure to pay the ransom. Victim organisations that refuse payment face having their data published on the group's dark web leak site.
