Description

Sinobi is a financially motivated threat group that employs a hybrid Ransomware-as-a-Service (RaaS) model. Emerging in mid-2025, it is characterized by a disciplined approach to attacks, extensive operational security, and a focus on stealth through living-off-the-land techniques.

Key insights

  • Utilizes a double-extortion model, threatening public disclosure of stolen data if ransom demands are not met.
  • Initial access is commonly gained through stolen VPN or Remote Desktop Protocol (RDP) credentials, often exploiting known vulnerabilities.
  • Employs sophisticated evasion tactics, including disabling endpoint protection, modifying firewall configurations, and data exfiltration using legitimate tools like Rclone.
  • Has been linked to past groups like Lynx and INC due to code overlaps and operational similarities.
  • Targets a diverse range of sectors, with notable attacks on organizations in healthcare and manufacturing.
