How your washing machine can steal computer files

A group of security researchers have revealed frightening new ways in which criminals can steal data from computer systems. Instead of breaking into the computer network via the Internet, hackers can simply infect an office printer and turn it into a radio using a piece of software. It sounds strange, but a Manhattan startup has demonstrated that it is certainly possible. The team is able to make devices such as printers, washing machines and air-conditioning units broadcast invisible, inaudible signals which can be picked up for miles around. Their method could lead to a new era for hackers. Currently the cyber security industry is focused on preventing unauthorized access to computer networks. Despite advances in protective measures, hackers keep finding new loopholes to exploit. The team demonstrated their method by infecting a Pantum laser printer and modifying its circuits so that it emitted electromagnetic radiation. By quickly switching the energy output back and forth, the printer can be made to emit radio waves that can transmit information. One of the few methods of detecting a hack of this kind is decidedly retro. By walking around your devices with an AM radio in hand, you can monitor whether the radio static is interspersed by a loud beeping noise. If so, the device is secretly transmitting radio signals.
