Iptables

Security checks for vulnerabilities and agentic risk

Overview

This skill is a low-quality generic iptables reference stub, but it does not show hidden access, credential use, persistence, network activity, or system changes.

Install only if you want a basic static placeholder reference. Do not rely on it for real iptables administration, because it lacks concrete commands, examples, and firewall-specific safety guidance.

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

Finding

The description says this is an 'Iptables reference tool' for working with iptables. However, the code only prints generic, templated prose about a vaguely named tool/concept and common sysops best practices. It never references real iptables operations in a meaningful way, does not provide actual iptables command syntax, examples, rule management guidance, or any interaction with the system firewall. This is therefore a material description-behavior mismatch: the implementation is a generic static text stub, not a genuine iptables reference tool.

Finding

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