In this "Post of the Week" video, we discuss the KRACK vulnerability that targets mobile devices and wireless routers.  This vulnerability targets the WPA2 security protocol that allows for encryption between a mobile device and a wireless router.  As the mobile device negotiates encrypted communication with the router, an attacker can force the mobile device to use very weak encryption (essentially no encryption at all) and thus see all the traffic between the device and the router.  We also talk about ways you can help avoid this problem.  Enjoy!
