APT37’s Ruby Jumper campaign demonstrates a mature approach to air-gap traversal.
Observed tradecraft includes:
• LNK-based initial execution
• Embedded PowerShell payload extraction
• Ruby interpreter abuse (v3.3.0)
• Scheduled task persistence (5-minute interval)
• USB-based covert bidirectional C2
• Multi-stage backdoor deployment
Toolset: RESTLEAF, SNAKEDROPPER, THUMBSBD, VIRUSTASK, FOOTWINE, BLUELIGHT.The removable media relay model enables:
– Command staging offline
– Data exfiltration without internet access
– Lateral spread across isolated systems
– Surveillance via Windows spyware
This reinforces a critical point:
Air-gap controls must extend beyond physical disconnection — including USB governance, device auditing, behavioral monitoring, and strict runtime execution policies.Are critical infrastructure operators prepared for USB-mediated C2 relays?
