Instrumenting machine code over WebRTC
summary
Demonstrates live machine‑code instrumentation over WebSockets and WebRTC using Frida 15 to inject a JavaScript agent into a running process, attach native functions and an interceptor, and schedule calls on the game’s main thread; reads health and shells (shells start at 25), simulates an attack by holding a key for ~50 ms, and pushes metrics to a Vue single‑page app. Adds a portal + WebRTC flow to expose a USB phone process remotely for low‑latency peer connections; the demos work end‑to‑end (health shown as −10 after suicide). Code is published.
