Chinese group behind 2009 Operation Aurora targeting Google and 20+ companies, pioneering zero-day supply chain attacks. This profile is mapped to MITRE ATT&CK G0066 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
Elderwood (also tracked as Elderwood Gang, Sneaky Panda) is a threat group attributed to China. The group primarily targets Defense, supply chain, technology for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0066 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 Elderwood include:
- Hydraq/Aurora
- Darkmoon
- Naid
Targeting & Operations
Elderwood operations focus on Defense, supply chain, technology. 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 Defense sector should treat Elderwood 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 Defense, supply chain, technology. Security researchers have documented campaigns involving Hydraq/Aurora 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 Elderwood:
- Network monitoring: Detect C2 beaconing patterns associated with Hydraq/Aurora and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1189 and T1195.002
- 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 G0066 in MITRE ATT&CK
