Groups Tool

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped local group-membership lookup with no evidence of privilege escalation, network access, persistence, or hidden behavior.

This appears safe for basic local group lookup. Before relying on it operationally, note that local account and group names may be displayed, and the included helper may not support all documented options.

A.I.G

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

# Groups - User Group Membership Checker

Display all group memberships for the current user or a specified system user. Group membership determines file access permissions and sudo privileges on Unix-like systems.

## Usage
Confidence
70% confidence
Finding
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
