Account data theft is one of the most common types of online fraud. Hackers often get passwords of smartphone owners using phishing, but often malicious software that cracks the camera of the device or records the actions of the owner right from the screen also happens. Recently, the network has information about a new kind of spyware software that can "steal" the cherished data in an even more extravagant way.
According to a joint study published by the University of Cambridge, hackers do not need to capture the screen to determine the password. Enough to use the gadget microphone – special software "by ear" will understand which of the characters on-screen keyboard has been selected. The selection method consists in determining the distance to the sound source at the moment when the finger touched the screen.
During the experiment, scientists achieved the recognition of 31 out of 50 four-digit pin codes with 10 attempts for each combination. The increase in password complexity, according to the researchers, will significantly complicate the task of hackers, but will not rule out the possibility of hacking completely. Users of the report authors recommended to be more attentive to the software that they install on their devices.
