Crypto exchanges face real Man‑in‑the‑Browser campaigns (Zeus Panda Ramnit Trickbot) that inject a one‑line first‑stage script into every endpoint, grab credentials, then prompt users to hand over 2FA and downgrade security. The demo uses a local proxy and a fake C2 to reproduce the flow, shows CSP and X‑Frame mistakes, and proves SMS/Google Auth are bypassable. A JavaScript real‑time monitoring agent leveraging Mutation Observers and checksums reports tampering to a backend and supports DOM healing; the proof‑of‑concept detects injections in seconds and can block or freeze risky actions.
