A touch is enough to steal all the data from your computer

The usual ways

If you want to break security and hack into a computer, you need to find security exploits in the program code or launch brute force attacks, neither of which is quick or easy enough. However, these are the usual ways hackers get into your computer.

Touch it

Aviv University has come up with a potentially much simpler way to swipe data from a computer: touch it.

If you make contact with a PC while you're wearing a digitizer wristband, you can measure tiny changes in electrical potential that reveal even stronger encryption keys (such as a 4,096-bit RSA key). You don't even have to touch the system directly in some cases -- researchers also intercepted keys from attached network and video cables.

While the attack is most effective using professional lab equipment, a regular mobile phone is sometimes good enough.
