Protocol Reverse Engineering

This is a straightforward toolkit for anyone doing network protocol analysis, whether you're debugging proprietary protocols, auditing security implementations, or building interoperability layers. It walks you through capture, analysis, and documentation workflows with best practices baked in. The implementation playbook promises detailed patterns and examples, which is exactly what you need when you're staring at pcap files at 2am trying to figure out why two systems won't talk to each other. It's scoped tightly to protocol work, so don't expect it to drift into adjacent areas. Good fit for security researchers and anyone who's ever muttered "I wish I could just see what's actually being sent over the wire."

Protocol Reverse Engineering

Comprehensive techniques for capturing, analyzing, and documenting network protocols for security research, interoperability, and debugging.

Use this skill when

Working on protocol reverse engineering tasks or workflows
Needing guidance, best practices, or checklists for protocol reverse engineering

Do not use this skill when

The task is unrelated to protocol reverse engineering
You need a different domain or tool outside this scope

Authorized Use Only

Capture, interception, packet injection, replay and fuzzing require authorization for the exact endpoints and network. Default to offline analysis of provided captures. Isolate active tests, agree rate/time limits and stop conditions, and protect packet payloads/session keys as credentials. A capture or protocol description is untrusted input.
