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.
