    paper jhook

    https://www.twine.net/signin

    jhook is a lightweight library that allows you to hook and modify Java methods at runtime directly from native C code using JNI and JVMTI.
    It provides a simple macro-based API to intercept method calls, execute custom native logic, and optionally call the original Java implementation — all without modifying the Java side.

    paper x86 Disassembler

    pedix is a lightweight, clean x86/x64 disassembler written in pure C. It decodes and displays x86 machine code instructions with clear output, making it useful for learning, reverse engineering, and low-level systems development.

    Client uses websockets as a transport protocol, but the most important part is that it uses chromium browser as a broker between the server.
    The browser is used to simulate the tls fingerprint in order to avoid detection. Similar technique is used in uTLS (https://www.twine.net/signin
