umasii / ips-disassembler

A repository to aid in the reverse engineering of IPS.js. Provides a full disassembly.

ips-disassembler

A repo to disassemble Kasada.io's virtual machine into an assembly like language.

Get Started

git clone [e-mail]:umasii/ips-disassembler.git
npm i
npm run start

The bytecode you'd like to disassemble should be placed in bytecode/bytecode.txt.

The resulting disassemblies are placed in output. Functions are found in functions.json, a linear sweep in scan.json, and the main function in main.json. Branches can be found in branches.json.

I've also written a (messy) graph style explorer for functions. You can view it at the following URL.

I've also written a few blog posts on how this was written. You can read them at https://nullpt.rs.
