The Qilin ransomware group, also known as Agenda, Gold Feather, and Water Galura, has emerged as a prominent threat, claiming over forty (40) victims monthly in 2025, reaching up to 100 cases in June. This ransomware-as-a-service (RaaS) operation has targeted more than 700 victims across sixty-two (62) countries, focusing primarily on sectors such as manufacturing, professional services, and wholesale trade. Qilin affiliates leverage leaked administrative credentials to gain initial access through VPN interfaces, followed by RDP connections for further system infiltration. They employ tools like Mimikatz and Cyberduck to harvest credentials and exfiltrate data, while also using legitimate software such as AnyDesk and ScreenConnect for remote access. The group’s sophisticated attack chain includes disabling security software using vulnerable drivers (BYOVD technique) and deploying Cobalt Strike for persistent remote access. A notable tactic involves using the Windows Subsystem for Linux (WSL) to execute Linux ransomware binaries on Windows systems, allowing them to bypass traditional security defenses focused on Windows PE behavior. This cross-platform capability enables Qilin to target both Windows and Linux systems. Qilin’s approach reflects a broader trend in the ransomware landscape, where groups employ a mix of legitimate tools and innovative methods to maximize impact and evade detection. This includes targeting Veeam backup infrastructure to compromise disaster recovery capabilities and utilizing fake CAPTCHA pages for initial payload delivery.
