YOUR COMPUTER COULD BE CRACKED BY A SMARTPHONE AS IT LISTENS TO IT RUNNING ENCRYPTION SOFTWARE

The hum made by your computer's microprocessor could be used by an eavesdropper to track your digital encryption keys, new research claims.

 

Researchers at Tel Aviv University in Israel have shown that merely listening to the quiet vibrations made by a computer can reveal what operations it is running.

 

Those sounds can be analysed so precisely, they claim, they can even reveal the details of encryption keys used for secure web browsing, credit card transactions and encrypted email.

 

Moreover, they say, the keys can be cracked within an hour using little more than a smartphone placed next to the targeted machine.

 

And the same technique, the study claims, can also analyse the fluctuations in electrical current flowing through the machine and measured by merely touching it for the same result.

 

The Tel Aviv team just yesterday published a paper outlining how the hack could be accomplished through a technique they have dubbed 'low-bandwidth acoustic cryptanalysis'.
