Thinking about today’s discussions about Malware in general, I found this story interesting and pretty relevant to what we did today. Researchers with MIT and Georgia Tech have developed a proof of concept to demonstrate that they can use a smartphone’s accelerometer to keylog a user’s computer. It can accurately decipher the keys from the vibrations of the keyboard when the smartphone is placed on a desk next to the keyboard.
According to Traynor, the method is 80 percent accurate with a 58,000 word dictionary. Even that accuracy, though, requires thoroughly modern equipment. “We first tried our experiments with an iPhone 3GS, and the results were difficult to read,” Traynor said in a statement. “But then we tried an iPhone 4, which has an added gyroscope to clean up the accelerometer noise, and the results were much better. We believe that most smartphones made in the past two years are sophisticated enough to launch this attack.”
The researchers said that the probability of a smartphone user falling victim to this attack as “pretty low”. It only has 80% accuracy and would then have trouble with username’s and passwords that would not be in a dictionary.
