- Attribution: China
- Active since: 2012
- Primary targets: ASEAN governments, military, telecom
- Also known as: Spring Dragon, Thrip, Billbug, Lotus Panda
Arsenal & Tools
Lotus Blossom employs a diverse arsenal of custom and shared tooling:
- Elise: Custom/shared tooling used in operations
- Evora: Custom/shared tooling used in operations
- Hanover: Custom/shared tooling used in operations
- custom backdoors: Custom/shared tooling used in operations
Targeting & Operations
The group focuses on ASEAN governments, military, telecom sectors, with operations spanning multiple geographic regions. Their campaigns typically involve carefully crafted spearphishing, strategic watering holes, and exploitation of public-facing applications.
Lotus Blossom 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.
