What Is Qilin Ransomware?

Qilin ransomware, also known in its earlier form as Agenda, emerged in 2022 and quickly evolved into one of the world’s most active ransomware-as-a-service (RaaS) operations. Affiliates deploy tailored ransomware builds written in Golang, Rust, and C, targeting both Windows and Linux (including VMware ESXi) environments.

Qilin incorporates a double-extortion strategy: not only does it encrypt victims’ systems, but it also exfiltrates sensitive data and threatens publication via its leak site to pressure victims into paying.

How Does Qilin Ransomware Work?

RaaS Affiliate Model: Operators supply affiliates with the infrastructure and customizable tools to stage attacks. Affiliates receive 80%–85% of ransom payments, retaining a high-profit margin.
Custom Built & Cross-Platform: Ransomware binaries are fine-tuned—affiliates can tailor encryption modes, file extensions, excluded targets, and process terminations to each victim’s environment.
Notable TTPs:
- Initial access via phishing, exposed remote services (e.g., VPN), or exploiting network vulnerabilities.
- Lateral movement using tools like PsExec, abuse of SCCM or VMware ESXi environments, and the exploitation of Fortinet vulnerabilities.
- Escalation & Cleanup: Deletion of shadow copies, clearing event logs, displaying ransom messages via printers, modifying wallpapers, and dismounting disk images to hinder recovery.
High-Impact Victims:
- In 2024, attacks on UK healthcare, including the Synnovis/NHS pathology service, caused severe disruptions and patient safety consequences.
- In 2025, Qilin surpassed 400 attacks globally—and was responsible for about 17% of July’s total ransomware incidents.
- Another high-profile case in August 2025 targeted pharmaceutical firm Inotiv, where nearly 176GB of data was stolen.

How Can I Protect Against Qilin Ransomware?

Combatting Qilin demands a multilayered cybersecurity approach:

Strengthen Defenses: Apply MFA, patch vulnerabilities promptly, especially on VPN and Fortinet devices—and block exposed remote access routes.
Segment & Secure: Segregate critical infrastructure such as VMware ESXi and SCCM. Monitor for anomalous lateral movements and atypical system behaviors.
Implement Resilience Measures: Maintain off-network backups, conduct regular restore drills, and deploy EDR solutions to detect non-standard activities like ransomware customization or data exfiltration.
Prepare Incident Response Plans: Given Qilin’s double-extortion behavior, prepare for ransomware negotiation, leak site contingencies, and communication strategies to mitigate reputational damage.
