This isn't the first time electromagnetic probing has been used to decipher encrypted data or that researchers have used unconventional methods to get into computers.

While the researchers jokingly placed the device in a pita, the reality is that someone could place one of these devices under the desk of a targeted subject to steal their encryption passkey. Fortunately, the researches alerted GnuPG developers about the attack and worked with them to adjust the software's algorithm. So you're safe for now. But keep a look out for errant pita sandwiches at the local Starbucks.
