Sinobi Ransomware

Sinobi is a ransomware threat group that has disclosed 274 victims in publicly accessible leak site data, representing 1.5% of all ransomware attacks tracked in this database. The earliest victim disclosure attributed to Sinobi in our dataset dates to May 2026.

Geographically, Sinobi has targeted organisations in 27 countries. The most frequently targeted nation is United States with 205 victim organisations. Other heavily targeted nations include India, United Kingdom, Canada.

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

Like most modern ransomware operations, Sinobi 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.
