Congrats guys! To those who wonder what a collision is. This happens when some other team already presented the same exploit before. The order of the teams‘ attempts is random. Thus, bad luck. Anyways, the development of such exploit chain earns much respect! Proud of you guys 🫶🏻

Today is the day. Tune in 6pm Swiss time to cheer #compasssecurity researchers to run their exploit 🤞

Wohoo. My fellow researchers got drawn 4th from 6 groups targeting the Ubiquiti AI Bullet in the Surveillance category on Wednesday, October 23 - 5pm 🤞
