Malware that tracks your keystrokes is nothing new. Every time you hit a key, certain data is inputted so a decent hack can simply track that data. However, researchers at IBM and Penn State are onto something entirely new. They’ve developed a new trojan that uses an Android phone’s motion sensors to track where one taps on a touchscreen. By cross-referencing this with the layout of a device’s digital keyboard, the trojan can reduce the number of possible four-digit PINs to only a handful of solutions 100 percent of the time. With a six-digit PIN, it returns a handful of PINs 80 percent of the time. Obviously, the researchers won’t release the trojan into the public, but with the knowledge of the hack now out there, it’s bound to fall into the wrong hands.
