Threat actor analysis
Blackshrantac has disclosed 43 victims on its leak site, 0.2% of all ransomware listings tracked in this database. Its earliest disclosure here dates to September 2025.
The group has listed organisations in 16 countries, most often in United States (9 victims), followed by India, Turkey, Peru.
By industry, its listings concentrate in Manufacturing, Technology, Financial Services — sectors that hold sensitive data or cannot tolerate long outages, both of which raise the pressure to pay.
Like most current ransomware operations, Blackshrantac is likely to use double extortion: data is stolen before files are encrypted, and organisations that refuse to pay are named on the leak site with the stolen data as leverage.
