That's my chain — a full chain w/ logic bugs only! No memory corruption, no AI, and of course no collisions at all 😉
Confirmed! Orange Tsai (@orange_8361) of DEVCORE Research Team (@d3vc0r3) chained 4 logic bugs to achieve a sandbox escape on Microsoft Edge, earning $175,000 and 17.5 Master of Pwn points. Full win! #Pwn2Own #P2OBerlin

🚗🔌 @Tesla patched our #Pwn2Own Automotive 2025 Wall Connector exploit with an anti-downgrade mechanism.
#Synacktiv experts bypassed it and replayed the same attack through the charging cable.

Mozilla says Mythos helped identify 271 vulnerabilities in Firefox 150.
I went through the commits, CVEs, and bug links to see what that number really means.
My takeaway: relax folks.
