Threat Actor Analysis

Blacknevas is a ransomware threat group that has disclosed 45 victims in publicly accessible leak site data, representing 0.2% of all ransomware attacks tracked in this database. The earliest victim disclosure attributed to Blacknevas in our dataset dates to August 2025.

Geographically, Blacknevas has targeted organisations in 19 countries. The most frequently targeted nation is United States with 11 victim organisations. Other heavily targeted nations include India, United Kingdom, Italy.

Industry-wise, Blacknevas shows a concentration in the Consumer 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, Blacknevas 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.
