Chinese group maintaining years-long persistence in F5 BIG-IP and other network appliances, demonstrating exceptional operational stealth. This profile is mapped to MITRE ATT&CK G1047 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
Velvet Ant (also tracked as None publicly documented) is a threat group attributed to China. The group primarily targets Large organizations, network devices for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G1047 in the MITRE ATT&CK framework. All techniques referenced in this report are mapped to ATT&CK for consistent threat modeling and detection engineering.
Arsenal & Tools
Known tools and malware associated with Velvet Ant include:
- PlugX
- custom implants for network devices
Targeting & Operations
Velvet Ant operations focus on Large organizations, network devices. The group typically gains initial access through spear-phishing, exploitation of public-facing applications, or strategic web compromises before deploying custom implants for persistent access and data exfiltration.
Organizations in the Large organizations sector should treat Velvet Ant as a relevant threat and validate their detection coverage against the MITRE ATT&CK techniques listed below.
