An Introduction To Web Application Security Systems

DumpBrowserSecrets is a post‑exploitation credential‑harvesting tool (EXE + DLL) that extracts saved passwords, cookies, OAuth refresh tokens, credit card data, autofill, and history from major browsers. It implements an App‑Bound Encryption bypass for Chromium browsers by spawning a headless Chromium process, injecting a DLL via Early Bird APC to call the IElevator COM interface and decrypt keys, and uses DPAPI/NSS handling for other browsers. The report covers operational evasion (string obfuscation, API hashing, PPID/argument spoofing, handle duplication), output format (JSON), attack scenarios, detection signals (injection, IElevator calls, non‑browser reads of browser DBs), and mitigation recommendations.
