Windows 11 still has some serious security flaws, Pwn2Own contestants find.
White hat hackers have managed to compromise Windows 11 three times in a single day during a recently held hacking contest, raising questions on the software’s security. The third and final day of the 2022 Pwn2Own Vancouver hacking contest saw three separate participants used zero-day vulnerabilities to crack open Microsoft’s latest operating system. The first contestant was nghiadt12 from Viettel Cyber Security, who abused a Windows 11 escalation of privilege exploit, via Integer Overflow. The second and the third ones were Bruno Pujos and vnhthp1712 from REverse Tactics, who used Use-After-Free and Improper Access Control vulnerabilities to escalate privileges on the target endpoint.
