Highly sophisticated group (attributed to NSA TAO) active since 2001, using HDD firmware implants and air-gap jumping capabilities. This profile is mapped to MITRE ATT&CK G0020 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
Equation (also tracked as None publicly documented) is a threat group attributed to United States. The group primarily targets Government, military, telecoms, energy globally for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0020 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 Equation include:
- EquationDrug
- GrayFish
- Fanny
- DoubleFantasy
Targeting & Operations
Equation operations focus on Government, military, telecoms, energy globally. 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 Government sector should treat Equation as a relevant threat and validate their detection coverage against the MITRE ATT&CK techniques listed below.
MITRE ATT&CK Mapping
Key techniques observed in Equation operations:
| Technique ID | Technique Name | Tactical Context |
|---|---|---|
| T1542.002 | T1542.002 | Observed in Equation campaigns |
| T1091 | T1091 | Observed in Equation campaigns |
| T1059.001 | T1059.001 | Observed in Equation campaigns |
| T1027 | T1027 | Observed in Equation campaigns |

Notable Campaigns
This threat group has been active in operations targeting Government, military, telecoms, energy globally. Security researchers have documented campaigns involving EquationDrug and other tools deployed against organizations in multiple countries. Attribution confidence varies by campaign, but consistent infrastructure and TTP overlap links activity to United States-nexus operations.
Detection & Defense
Recommended defensive measures against Equation:
- Network monitoring: Detect C2 beaconing patterns associated with EquationDrug and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1542.002 and T1091
- 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 G0020 in MITRE ATT&CK
