Hey guys! Just recently finished up my new article about Besder (actually XiongMai) net cams. I did a bunch of fuzzing, and found a neat unprivileged DoS exploit for the camera. Wanted to give a shoutout to @bcardiff and the other guys at Manas for reaching out to me with words of encouragement and sending me a gift card to get a new camera. Stay tuned for more articles!

You can watch a demo of the exploit on Youtube.
