Each of them earned $150,000 for successfully demonstrating their Microsoft Teams zero-days.
Other highlights from the first day of Pwn2Own include Marcin Wiązowski, Team Orca of Sea Security, and Keith Yeo demonstrating more zero-days in Windows 11 and Ubuntu Desktop,.
On the second day, Pwn2Own competitors will attempt to exploit zero-days in the Tesla Model 3 Infotainment System and Diagnostic Ethernet, Windows 11, and Ubuntu Desktop.
