Windows 11 hacked multiple times by security researchers at Pwn2Own Berlin 2025

Trend Micro’s Pwn2Own event in Berlin showcased security researchers testing system vulnerabilities, with significant rewards incentivizing them to uncover and exploit flaws. On the first day alone, multiple successful breaches of Windows 11 were achieved through various exploits, including UAFs and integer overflows. Researchers like Chen Le Qi and Marcin Wiązowski earned substantial rewards for their efforts, demonstrating the growing importance of identifying system weaknesses in high-profile operating systems. With two more days remaining, there’s plenty of opportunity to see further compromises of Windows 11.
