Hacking Tools, Hacker News & Cyber Security

DumpBrowserSecrets is a post-exploitation credential-harvesting tool that extracts saved passwords, session cookies, OAuth refresh tokens, credit card numbers, autofill data, and browsing history from major Chromium- and Gecko-based browsers. It bypasses Chrome's App‑Bound Encryption by spawning a headless Chromium process and injecting a DLL (Early Bird APC) to use the IElevator COM interface to decrypt keys, handles DPAPI and NSS models for other browsers, includes operational evasion features (string obfuscation, API hashing, PPID/argument spoofing, handle duplication), writes structured JSON output, and is positioned for red-team/assumed-breach use but would also enable rapid lateral movement and SaaS/cloud account takeover if used by malicious actors.
