Threat Actor Analysis
Worldleaks is a ransomware threat group that has disclosed 177 victims in publicly accessible leak site data, representing 0.8% of all ransomware attacks tracked in this database. The earliest victim disclosure attributed to Worldleaks in our dataset dates to May 2025.
Geographically, Worldleaks has targeted organisations in 29 countries. The most frequently targeted nation is United States with 95 victim organisations. Other heavily targeted nations include United Kingdom, Brazil, Germany.
Industry-wise, Worldleaks shows a concentration in the Healthcare, Manufacturing, Business Services 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, Worldleaks 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.
