Chinese group targeting satellite operators, telecoms, and defense organizations in Southeast Asia and the US. This profile is mapped to MITRE ATT&CK G0076 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
Thrip (also tracked as None publicly documented) is a threat group attributed to China. The group primarily targets Satellite, telecoms, defense, Southeast Asia for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0076 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 Thrip include:
- Rikamanu
- Catchamas
- Syndicasec
Targeting & Operations
Thrip operations focus on Satellite, telecoms, defense, Southeast Asia. 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 Satellite sector should treat Thrip as a relevant threat and validate their detection coverage against the MITRE ATT&CK techniques listed below.

Notable Campaigns
This threat group has been active in operations targeting Satellite, telecoms, defense, Southeast Asia. Security researchers have documented campaigns involving Rikamanu and other tools deployed against organizations in multiple countries. Attribution confidence varies by campaign, but consistent infrastructure and TTP overlap links activity to China-nexus operations.
Detection & Defense
Recommended defensive measures against Thrip:
- Network monitoring: Detect C2 beaconing patterns associated with Rikamanu and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1059.001 and T1005
- Email security: Implement robust phishing defenses including URL sandboxing and attachment detonation
- Patch management: Prioritize patching of internet-facing applications exploited by this group
- Threat hunting: Proactively hunt for IOCs and behavioral indicators mapped to G0076 in MITRE ATT&CK
