Most security researchers focus on finding low level vulnerabilities and fixing them before they're exploited by hackers, but a team of Israeli academics have taken the task of finding the most peculiar methods of eavesdropping on a PC that wouldn't typically cross your mind.

Hackers who want to steal sensitive data from computers can sometimes get very creative with their methods, but most of the time they exploit bad security practices and software vulnerabilities to achieve their goals. Sometimes, hackers use popular tools of the trade to hack other hackers, but that skill level is relatively rare.

Researchers at the Ben Gurion University in Israel aren't leaving any stones unturned however. They've built a reputation of finding peculiar but feasible techniques for stealing data from so-called air-gapped PCs -- systems that are physically isolated with no Internet access -- without being detected.
