Security audit

Antlr4

Security checks for vulnerabilities and agentic risk

Overview

This is a simple ANTLR4 reference skill that prints static documentation and does not show credential access, networking, persistence, or destructive behavior.

This skill appears safe to install as a static reference helper. Be aware that its content is generic and includes broad credential/security advice, but inspection did not find code that accesses secrets or changes your system.

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

Credential Access

High
Category
Privilege Escalation
Content
## Prerequisites
- Basic understanding of devtools concepts
- Required tools and access credentials
- System meeting minimum requirements

## Installation
Confidence
70% confidence
Finding
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
