Threat actor analysis
Section9 has disclosed 19 victims on its leak site, 0.1% of all ransomware listings tracked in this database. Its earliest disclosure here dates to July 2026.
The group has listed organisations in 11 countries, most often in Brazil (6 victims), followed by United States, Belgium, Japan.
By industry, its listings concentrate in Technology, Financial Services, Other — sectors that hold sensitive data or cannot tolerate long outages, both of which raise the pressure to pay.
Like most current ransomware operations, Section9 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.
