Threat Actor Analysis

Crypto24 is a ransomware threat group that has disclosed 47 victims in publicly accessible leak site data, representing 0.2% of all ransomware attacks tracked in this database. The earliest victim disclosure attributed to Crypto24 in our dataset dates to April 2025.

Geographically, Crypto24 has targeted organisations in 24 countries. The most frequently targeted nation is United States with 8 victim organisations. Other heavily targeted nations include Singapore, Indonesia, Malaysia.

Industry-wise, Crypto24 shows a concentration in the Technology, 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, Crypto24 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.
