Mike Weber from Coalfire was this week’s guest, and he told the team about an experiment where they were able to cause 3D printers to catch fire with a remote attack. Mike also gave an update on a story from several episodes ago where 2 of his coworkers were arrested during a physical pen-testing job at a courthouse in Iowa. Then, in the news, the crew discussed Apple’ WWDC announcements including macOS 11 Big Sur and the move from Intel to ARM chips. In other news, they reviewed a massive DDoS attack Amazon mitigated, how hackers used Google Analytics to steal credit cards, and how Windows 10 managed to slash RAM usage for Chrome and Edge browsers.
