Project description
The project does research on covert channels of air-gapped systems. The focus lies on exfiltrating data through electromagnetic signals from air-gapped systems, while at the same time developing a defense system.
Context
The project context is critical infrastructure. These are essential systems or assets, for example, military networks of the army.
To protect such systems, air-gapping is often used as a security measure.
In the context of critical infrastructure, understanding and defending against these advanced attack vectors is essential to safeguarding national security and public safety.
Results
The project has replicated the electromagnetic attack method by using the power supply with On-Off Keying (OOK)modulation.
A corresponding receiver is also included, capable of capturing and processing the signals.
On the defense side, it is possible to monitor CPU processes and USB activity.
