4th place after two days of #pwn2own in Berlin. Fingers crossed for the 3rd day and our colleagues attempt on Claude Code.
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
