Cybersecurity researchers have detailed a post-exploitation technique that enables the Chrome DevTools Protocol (CDP) inside a running Google Chrome or Microsoft Edge process on Windows, allowing an operator to access cookies, saved data, and authenticated browser sessions. The technique assumes that an operator already has code execution on the Windows host and does not involve exploiting a Chrome or Edge security vulnerability. The requirement for prior code execution and sufficient access to manipulate the target process places the technique in a narrower post-compromise scenario than a remotely exploitable browser flaw. SpecterOps said defenders can look for signs of process injection targeting chrome.exe and msedge.exe using Sysmon Event IDs 8 and 10. "Since App-Bound Encryption was enabled, we've seen an increase in attackers using Chrome Remote Debugging to extract cookies," Google said in a March 2025 post . Google changed C...
