Tcpdump

Security checks for vulnerabilities and agentic risk

Overview

This skill is a low-impact static help script, but its tcpdump reference content is mostly generic placeholder text and should not be relied on as authoritative.

Installing this skill appears unlikely to create a security risk because it only prints local static text, but it is not a dependable tcpdump reference. Users should verify tcpdump commands and security guidance against official documentation or trusted references before acting on it.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

MCP Tool Poisoning
Confidence

Finding

The declared purpose suggests a reference tool specifically for tcpdump. However, the code only implements a menu of static text pages containing generic, boilerplate guidance that could apply to many tools. It does not invoke tcpdump, parse captures, provide accurate tcpdump command documentation, or otherwise behave as a substantive tcpdump reference. There are no undeclared sensitive capabilities or resource accesses, but there is a material mismatch between the claimed specialized purpose and the actual generic placeholder behavior.

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The file header states 'tcpdump — Tcpdump reference tool', yet the implemented help topics and body text discuss generic installation, credentials, migration, data export/import, indexing, batching, and community forums rather than tcpdump reference behavior. This is more than incomplete documentation: the comments label the script as a tcpdump-focused reference while the content materially targets a different, generic template-like purpose.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The manifest and top-level comment describe a 'Tcpdump reference tool', which implies command-specific guidance about the tcpdump packet-capture utility. Instead, the command outputs are largely boilerplate text about generic devtools concepts, migration, security, performance, and credentials, with almost no tcpdump-specific commands, syntax, filters, or usage details.
