Their efforts earn them $20,000 and 2 Master of Pwn points. (Sound On) Confirmed! The team from used a stack-based buffer overflow to take over an HP LaserJet and turn it into a jukebox.
The third day of Pwn2Own also saw the F-Secure Labs team turning an HP LaserJet printer into a jukebox using a stack-based buffer overflow to play AC/DC's Thunderstruck. However, despite their success and winning $25,000, their attempt was tagged as a "collision" after it was revealed that they used a bug known to the vendor. Mr L and Nguyễn Hoàng Thạch ( of STARLabs were able to get code execution on the Samsung Galaxy S21 on the second day of Pwn2Own. The Samsung Galaxy S21 escaped a hacking attempt on the first day after F-Secure Labs' Ken Gannon didn't get his zero-day exploit to work within the allotted time. Sam Thomas ( from team Pentest Limited ( was the one who compromised the Samsung Galaxy S21 running the latest Android 11 security updates on the third day using a unique three-bug chain and earning $50,000. On the other hand, if you did actually buy a Huawei phone with the intent of flashing a custom ROM on it, better act fast and unlock its bootloader while you can.Pwn2Own Austin 2021 final leaderboard (ZDI) Only hardcore flashers of custom ROMs would be interested in the bootloader unlocking procedure, and as Android has matured less and less people are going that route. It's also possible that this service didn't get a lot of interest from its customers.Īfter all, we'd venture a guess and say not a lot of people know what a bootloader is or why they'd want to unlock it.
The stated reason for this move implies that ROM flashing caused various issues. Huawei says it's going to continue to provide you with quality services, but evidently bootloader unlocking is no longer going to be one of them. For products released before today, it will continue to work only for the next 60 days. For every product launched after today, May 24, this will not be available at all. Huawei has quietly announced that it's discontinuing its bootloader unlock code application service.
