The latest threat to your cybersecurity is ... pita bread? That's right. Researchers at Tel Aviv University in Israel have developed a way to steal computer passwords using a radio receiver and one piece of pita.
Some laptops give off electromagnetic radiation, and the researchers found they could pick up that radiation with a radio receiver and use it to find password information.
Laptops running encryption programs could be fooled into revealing passwords when sent encrypted passages of text. Laptops would then encrypt the data, and researchers used components from a radio to pick up the changes in the electromagnetic radiation as the laptop's CPU works.
The pita bread doesn't actually steal your password. Instead, it's used to hide the gadget. That way, hackers could steal password data in coffee shops and other public settings without drawing unwanted attention. So, the pita bread could probably be replaced by any food of a similar size and shape.
The data is stored on a microSD card, which can be either accessed via Wi-Fi or manually retrieved. Researchers can look at the graph and decipher the password from the change in the signal.
According to the researchers, they can use the extracted information to find out a password in a manner of seconds.
