Hands-On IoT Hacking: Rapid7 at DEF CON 30 IoT Village, Part 1

Rapid7 was back this year at DEF CON 30 participating at the IoT Village with another hands-on hardware hacking exercise, with the goal of teaching attendees' various concepts and methods for IoT hacking. Over the years, these exercises have covered several different embedded device topics,...

GPG 32-Bit Short Key ID Collision Attacks

Attack and vulnerability details are often disclosed in order to prompt vendors and project maintainers into action. It happened recently with publication of attack code that mimicked the work of Karsten Nohl on BadUSB and tried to nudge Phison Electronics of Taiwan into looking at its USB...

Hackers publish the BadUSB fix patch only applies to the latest version of the group with the USB 3.0 firmware-bug warning-the black bar safety net

Last week, two hackers announced they had the BadUSB code reverse engineering, and on GitHub published. As for the reason for this, is to give the industry the pressure is applied, in order to quickly come up with a solution--although doing so will also make the user more vulnerable to face...
