Atreus is an open-source anti-ransomware tool designed to identify, mitigate, and neutralize Ryuk ransomware threats on Windows endpoints.
Anti-Ransomware to mitigate and neutralize Ryuk Threat.
Atreus is used by security researchers, endpoint security professionals, and IT administrators to detect and respond to Ryuk ransomware activities on Windows machines. It provides monitoring and tracing capabilities to help identify malicious behaviors associated with Ryuk, offering an additional layer of defense during incident response or research.
Atreus is not intended as a production-grade countermeasure but as a research and mitigation tool; it should be executed in isolated virtual environments to avoid accidental infection. Users must avoid connecting the VM to any network during ransomware execution and use different host and guest OS platforms to reduce evasion risks.
