Arsenal & Tools
Mustang Panda employs a diverse arsenal of custom and shared tooling:
- PlugX: Custom/shared tooling used in operations
- ToneShell: Custom/shared tooling used in operations
- TONEDROP: Custom/shared tooling used in operations
- Cobalt Strike: Custom/shared tooling used in operations
- DOPLUGS: Custom/shared tooling used in operations
Targeting & Operations
The group focuses on government, NGOs, think tanks in Europe, Asia sectors, with operations spanning multiple geographic regions. Their campaigns typically involve carefully crafted spearphishing, strategic watering holes, and exploitation of public-facing applications.
Mustang Panda is characterized by persistent, long-term access operations. Once inside a target network, the group establishes multiple redundant persistence mechanisms and moves laterally to high-value systems before beginning data exfiltration.
