On the first day of Pwn2Own Berlin 2026, security researchers collected $523,000 in cash awards after exploiting 24 unique zero-days.

Today’s highlight was Orange Tsai’s attempt, who was awarded $175,000 in rewards after chaining 4 logic bugs to achieve a sandbox escape on Microsoft Edge.

Windows 11 was also hacked three times by Angelboy and TwinkleStar03 (working with the DEVCORE Internship Program), Marcin Wiązowski, and Kentaro Kawane of GMO Cybersecurity, each earning $30,000 in cash rewards for demonstrating new privilege escalation zero-days.
