Security audit

Apparmor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a low-capability AppArmor-themed reference wrapper that prints generic text and does not access files, credentials, networks, or persistence mechanisms.

Install only if you understand this is a generic reference scaffold, not an authoritative AppArmor guide. Do not rely on it for production AppArmor configuration, enforcement, or troubleshooting decisions without checking real AppArmor documentation.

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
Vulnerability Patterns

MCP Tool Poisoning
Confidence

Finding

The skill presents itself as an AppArmor reference tool, but the provided content is only a generic command scaffold and does not demonstrate real AppArmor-specific guidance or behavior. This can mislead operators into trusting inaccurate or incomplete security advice in a sysops context, increasing the chance of misconfiguration or unsafe operational decisions.

Credential Access

Confidence
70% confidence
Finding

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

Intent-Code Divergence

Confidence
90% confidence
Finding

The file header explicitly states that this is an 'Apparmor reference tool' for sysops contexts. However, the body of the script mainly emits broad, reusable documentation text that could apply to many tools or platforms, creating an intent-to-implementation mismatch in the documentation itself.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest and header describe the skill as an 'Apparmor reference tool' for sysops work, which implies substantive AppArmor-specific guidance. Instead, the command outputs contain placeholder-like, domain-generic advice about networking, migration, security, and performance, with little to no concrete AppArmor concepts, commands, profiles, enforcement modes, or troubleshooting specifics.
