The attacker is also able to collect information even from computers with wireless keyboards or notebooks running on battery by a laser beam, which recognizes unique vibration of each typed key. However, don’t worry too much. Just watch out, the weak point of these methods is that computers under attack should be in direct view of hackers. Consequently, by knowing and preventing these hacker methods, people can reduce the risk of losing their private information. To read the whole article please click here.
