Nigerian cybercrime group conducting business email compromise (BEC) campaigns responsible for billions in global losses. This profile is mapped to MITRE ATT&CK G0083 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
SilverTerrier (also tracked as None publicly documented) is a threat group attributed to Nigeria. The group primarily targets Global, BEC targets for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0083 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 SilverTerrier include:
- Commodity RATs (LokiBot
- AgentTesla
- PredatorPain)
Targeting & Operations
SilverTerrier operations focus on Global, BEC targets. 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 Global sector should treat SilverTerrier 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 Global, BEC targets. Security researchers have documented campaigns involving Commodity RATs (LokiBot and other tools deployed against organizations in multiple countries. Attribution confidence varies by campaign, but consistent infrastructure and TTP overlap links activity to Nigeria-nexus operations.
Detection & Defense
Recommended defensive measures against SilverTerrier:
- Network monitoring: Detect C2 beaconing patterns associated with Commodity RATs (LokiBot and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1566.001 and T1059.005
- 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 G0083 in MITRE ATT&CK
