Threat Actor Analysis

Abyss is a ransomware threat group that has disclosed 62 victims in publicly accessible leak site data, representing 0.3% of all ransomware attacks tracked in this database. The earliest victim disclosure attributed to Abyss in our dataset dates to January 2024.

Geographically, Abyss has targeted organisations in 14 countries. The most frequently targeted nation is United States with 43 victim organisations. Other heavily targeted nations include Canada, Germany, Hong Kong.

Industry-wise, Abyss shows a concentration in the Business Services, Technology, Healthcare 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, Abyss 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.
