Patch In, Exploit Out: How deepsec Reconstructed the Pwn2Own Microsoft Edge Sandbox Escape
Summary
Deepsec reconstructed the Microsoft Edge sandbox-escape exploit chain demonstrated at Pwn2Own Berlin, showing a multi-bug sequence rather than memory corruption, and used AI-assisted analysis to assemble a complete chain from pre- and post-patch binaries. The article discusses patch analysis, navigation and UXSS primitives, and the implications for patch transparency and defense effectiveness.
