That's a wrap on Pwn2Own Berlin 2026! 🏆 $1,298,250 awarded. 47 unique 0-days. 3 days of absolute chaos. And talk about main character energy - congrats to DEVCORE for claiming Master of Pwn with 50.5 points and $505,000 - they never slowed down. See you next year! #Pwn2Own #P2OBerlin
Another collision! Although successful on stage, @rewhiles of Viettel Cyber Security (@vcslab) targeting Anthropic Claude Code in the Coding Agent category used a bug that was previously known to the vendor. They still earn $20,000 and 2 Master of Pwn points. #Pwn2Own #P2OBerlin
Locked in! Le Duc Anh Vu (@vulda17) of Viettel Cyber Security (@vcslab) exploited Cursor, earning $30,000 and 3 Master of Pwn points. Full win! #Pwn2Own #P2OBerlin
2025 has seen many great web security findings. Honored that @_l0gg's SharePoint ToolShell pre-auth RCE (CVE-2025-53770) is nominated for @PortSwigger Top 10 Web Hacking Techniques 2025. If you're in the community, your vote would mean a lot: portswigger.net/polls/top-10-w… Thanks!
We have another collision. Team Viettel used two bugs to exploit the Lexmark CX532adwe. While their heap based buffer over was unique, the other bug has been seen earlier in the contest. They still earn $7,500 and 1.5 Master of Pwn points. #Pwn2Own
Confirmed! namnp of Viettel Cyber Security used a crypto bypass and a heap overflow to exploit the Phillips Hue Bridge. They earn $20,000 and 4 Master of Pwn points, which catapults them in the Top 5. It also puts us over $1,000,000 for the contest! #Pwn2Own
🏠Boom! @ViettelCyberSec kicks off Day 2 of #Pwn2Own Ireland as they slip past the @home_assistant Green’s defenses! Smart home, smarter hack. They head off for the first disclosure of the day. #P2OIreland
