Well done by everyone who participated. Great to see the breadth of bugs found and how professional these researchers are.
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

That's a wrap on Day 2 of #Pwn2Own Berlin! Day Two added $385,750 and 15 unique 0-days, bringing event totals to $908,750 for 39 unique vulnerabilities. DEVCORE leads Master of Pwn with 40.5 points — but the fun ain't over yet, we've got one more day to go. See you tomorrow! #P2OBerlin
