Security researcher Ankit Anubhav, principal researcher at NewSky Security, has discovered nearly 700 Brother printers left exposed online. Anyone can access the administration panel of the printers and take control of the devices. The printers belong to corporate and government networks and known universities. An attacker can exploit the exposed administration panel to deliver tainted firmware and take full control. An attack could include spyware-like behavior in tainted firmware updates and have printers send copies of printed documents to an attackers server.”]
