Chinese threat group targeting semiconductor and airline industries for intellectual property theft, using Cobalt Strike and custom DLL loaders. This profile is mapped to MITRE ATT&CK G0114 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
Chimera (also tracked as None publicly documented) is a threat group attributed to China. The group primarily targets Semiconductor, airline industry for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0114 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 Chimera include:
- Cobalt Strike
- custom loaders
Targeting & Operations
Chimera operations focus on Semiconductor, airline industry. 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 Semiconductor sector should treat Chimera as a relevant threat and validate their detection coverage against the MITRE ATT&CK techniques listed below.
