20 years ago, china hide 2nd network card that was in listener mode, transmitting documents at random times, mostly peek. This was at a research company. How it was discovered. We put a card on listening/prem mode and mirror everything for that subnet the printer was on. I thought I screwed it up with the double mirror/traffic.
when investigating why the issue, we found nothing wrong with the config, only when we plugged it to another network, we discovered it was something on the network. We narrow it down quickly to the printer. We told head of security (we were hired for an audit ) and it soon became known it was stealing trade secrets and sending them overseas.
that was 20 years ago, and till this day, I remember anytime someone says china doesn't steal technology... I remember this printer. this was done at the state level and was caught.
