Hackers can steal data via the sounds of a hard drive
Just about anytime you think you and your computer are safe from hackers and security weaknesses, some bizarre, unexpected method or flaw gets discovered. Case in point: security researchers have come up with a way to steal data from a computer's hard drive just by listening to the sounds it makes. Not only can information be transmitted without a users' knowledge, but their computer doesn't even need to be connected to the internet.
Called DiskFiltration, the hack works by taking control of a hard drive's actuator, or the arm that moves back and forth across the platters when reading and writing data. These movements make various noises — the kind you usually hear when first booting up a desktop PC.
