A group of researchers from the iTrust, a research center at the Singapore University of Technology and Design, has demonstrated how to use a Drone to intercept wireless printer transmissions from outside an office building. The drone carries a smartphone which runs two custom apps that are capable of intercepting wireless traffic of the printer which contains sensitive data. The researchers accessed a corporate network by using a smartphone-equipped drone to hack internal printers. The attack is very insidious and it is difficult to detect, once a victims document is intercepted it is sent to an attackerS Dropbox account using the smartphone connection.”]
