This is information that does not reassure specialists in computer security. Four Israeli researchers have managed to hack into a computer using the electromagnetic waves emitted by the processor ...
See This : Car without driver could be hacked !!!
The researchers demonstrated that it was possible to steal a data encryption key on an RSA-type algorithm, placing an antenna to forty centimeters PC and recovering the electromagnetic waves emitted by the processor at the time of encryption information!
Hack a PC without touching it and without internet connection, it is now possible!
Rather worrying, because with an encryption key, it is possible to reform the data in clear, as if you were the owner of the information. The four researchers from the University of Tel Aviv, did not have to pay big money to achieve this feat, they account for about 260 euros of electronic components, everyone could do the same.
For the record and to show that you can be 40 centimeters from a computer, without arousing suspicion from its owner, they concealed their antenna in a pita place on a desk. According to these experts, it only takes seconds to reach recover the encryption key, without the need for any contact with the same PC or internet connection!
It was enough to use the electromagnetic waves emitted by the CPU to hack GnuPG
To understand how it is possible to retrieve information from these waves amidst all the waves emitted by the processor, be aware that data encryption is particularly intensive system resources, and it goes through several phases, which implies an electromagnetic wave overload characteristics that simply collect and then analyze to reform the encryption key. This is how the researchers were able to hack the encryption solution GnuPG ...
4 The researchers will present this discovery in the month of September in Saint-Malo, on the occasion of the CHES 2015 conference cryptological GnuPG has already made a patch to its software, but it opens new questions in the field of security computers, because hackers know that it is now possible to hack a PC via the airwaves it emits ... Until we sell we Faraday cages for PC, there is only not!
