Cloud-focused group targeting misconfigured Docker and Kubernetes environments to deploy cryptocurrency miners and steal credentials. This profile is mapped to MITRE ATT&CK G0139 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
TeamTNT (also tracked as None publicly documented) is a threat group attributed to Germany. The group primarily targets Cloud, Docker, Kubernetes environments for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0139 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 TeamTNT include:
- TNTbotinger
- Tsunami
- Chimaera
- custom miners
Targeting & Operations
TeamTNT operations focus on Cloud, Docker, Kubernetes environments. 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 Cloud sector should treat TeamTNT 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 Cloud, Docker, Kubernetes environments. Security researchers have documented campaigns involving TNTbotinger and other tools deployed against organizations in multiple countries. Attribution confidence varies by campaign, but consistent infrastructure and TTP overlap links activity to Germany-nexus operations.
Detection & Defense
Recommended defensive measures against TeamTNT:
- Network monitoring: Detect C2 beaconing patterns associated with TNTbotinger and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1496 and T1059.004
- 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 G0139 in MITRE ATT&CK
