Hackers Don't Need Wi-Fi to Steal Your Data

The researchers are tracing leaks of electromagnetic radiation that are byproducts of various electronic components of computer hardware, including computer processors and capacitors.

Some of the signals are created when you type at the keyboard and can be picked up with the right kind of electronic eavesdropping equipment.
In their recent study, the Georgia Tech researchers developed a way to measure the strength of the emissions and offer ways for hardware and software designers to plug those electronic holes.
So far, these kinds of leaks are not overly exploited by hackers.
“If you are comparing this to Internet attacks, it is less of a problem,” said Alenka Zajic, assistant professor of electrical and computer engineering at the Georgia Institute of Technology.
“But they are very hard to detect. With any sort of Internet attack, you will find the attacker. With this one you just need to be close by and there’s no way to know who took your data.”

Cool Jobs: Hacker

Zajic and her colleagues say they were able to pick up keystroke information from laptops using just an AM radio and a cellphone. “You could probably hide it under the desk,” Zajic said. “It’s just a matter of motivation.”
These side-channel emissions can also be measured from hidden antennas in a briefcase, while acoustic emissions from the device’s electronic capacitors, can be picked up by tiny microphones.
