dsl-vm-reverse

authentic

Reverse JavaScript-based custom DSL/VM interpreters and risk-control engines: identify IIFE/switch-based opcode dispatch, extract opcode tables, and capture runtime semantics.

When to use

• A protected web asset runs a custom bytecode VM (risk-control/captcha engines).
• Recovering opcode semantics from a JS interpreter loop.

When not to use

• Custom VMs vary wildly; methodology transfers but specifics do not.
• Runtime capture requires controlling the execution environment.
