analyzing-protocols
Analyzes network protocol implementations to identify parsing vulnerabilities, state machine issues, and protocol-level security problems. Use when analyzing network servers, protocol handlers, or investigating protocol implementation bugs.
Best use case
analyzing-protocols is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Analyzes network protocol implementations to identify parsing vulnerabilities, state machine issues, and protocol-level security problems. Use when analyzing network servers, protocol handlers, or investigating protocol implementation bugs.
Teams using analyzing-protocols should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Protocol Analysis ## Detection Workflow 1. **Identify protocol handlers**: Find network socket handlers, locate packet parsing functions, identify protocol state machines, map protocol message types 2. **Analyze protocol messages**: Identify message formats, parse message fields, check field validation, assess length handling 3. **Trace protocol state**: Map state transitions, identify state variables, check state machine completeness, assess state corruption potential 4. **Assess security**: Check authentication and authorization, verify input validation, assess exploitability, identify protocol-level attacks ## Key Patterns - Protocol parsing vulnerabilities: buffer overflows in packet parsing, integer overflow in length fields, format string in protocol handling, command injection in protocol commands - State machine issues: out-of-order message handling, missing state transitions, state corruption attacks, protocol state confusion - Authentication flaws: weak authentication mechanisms, missing authentication on critical operations, authentication bypass opportunities, session management issues - Protocol logic errors: race conditions in protocol handling, TOCTOU in protocol operations, improper input validation, protocol downgrade attacks ## Output Format Report with: id, type, subtype, severity, confidence, location, protocol, vulnerability, packet_field (name, offset, size), overflow_scenario, attack_vector, exploitable, impact, mitigation. ## Severity Guidelines - **CRITICAL**: Remote code execution via protocol vulnerability - **HIGH**: Remote DoS or information disclosure - **MEDIUM**: Local protocol issues - **LOW**: Minor protocol bugs ## See Also - `patterns.md` - Detailed detection patterns and exploitation scenarios - `examples.md` - Example analysis cases and code samples - `references.md` - CWE references and mitigation strategies
