Financially motivated group physically planting rogue devices (Raspberry Pi, Bash Bunny) inside bank offices for network penetration. This profile is mapped to MITRE ATT&CK G0105 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
DarkVishnya (also tracked as None publicly documented) is a threat group attributed to Eastern Europe. The group primarily targets Banks in Eastern Europe for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0105 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 DarkVishnya include:
- Physical implants
- DarkVishnya backdoor
Targeting & Operations
DarkVishnya operations focus on Banks in Eastern Europe. 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 Banks in Eastern Europe sector should treat DarkVishnya 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 Banks in Eastern Europe. Security researchers have documented campaigns involving Physical implants and other tools deployed against organizations in multiple countries. Attribution confidence varies by campaign, but consistent infrastructure and TTP overlap links activity to Eastern Europe-nexus operations.
Detection & Defense
Recommended defensive measures against DarkVishnya:
- Network monitoring: Detect C2 beaconing patterns associated with Physical implants and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1200 and T1133
- 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 G0105 in MITRE ATT&CK
