Chinese group targeting Central Asian government entities using Dropbox and other cloud services as C2 infrastructure. This profile is mapped to MITRE ATT&CK G0136 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
IndigoZebra (also tracked as None publicly documented) is a threat group attributed to China. The group primarily targets Central Asian governments for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0136 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 IndigoZebra include:
- xCaon
- BoxCaon
Targeting & Operations
IndigoZebra operations focus on Central Asian governments. 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 Central Asian governments sector should treat IndigoZebra 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 Central Asian governments. Security researchers have documented campaigns involving xCaon 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 IndigoZebra:
- Network monitoring: Detect C2 beaconing patterns associated with xCaon and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1566.001 and T1204.002
- 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 G0136 in MITRE ATT&CK
