Wireless routers are the most often attacked and exploited type of IoT device. They are also one of the rare IoT devices that most of us can’t do without. We need them to be as secure as can be, but unfortunately, most of them are not.
The non-profit American Consumer Institute Center for Citizen Research (ACI) has tested the latest available versions of the firmware of 186 Wi-Fi routers present in the U.S. market and found that 155 (83%) of them contain known open source vulnerabilities.
The tested firmware is for devices by TP-Link, Asus, AVM, Belkin, Cerio, D-Link, HPE, Linksys, NETGEAR, Sierra Wireless, TRENDnet, Ubiquiti Networks, Yamaha and Zyxel.
