Multiple critical vulnerabilities in Ruckus Wi-Fi routers used throughout the world were disclosed at the 36th Chaos Communication Congress (CCC) in Leipzig, Germany, held from December 27-30, 2019.
Ruckus offers high-end wirelesss networking gear that provides mesh Wi-Fi (called 'Unleashed') and regular routers to hundreds of thousands of customers. The mesh Wi-Fi is common in conferences (it was used at Black Hat last year), airports, hotels and other large areas that require Wi-Fi access. It is used, for example, in conjunction with Google Station to deploy public Wi-Fi hotspots throughout Sao Paulo in Brazil, and in similar configurations in India, Mexico and Indonesia. Organizations also use Ruckus to provide company-wide Wi-Fi networks.
