Malware Analyst

Security checks for vulnerabilities and agentic risk

Overview

This skill is a malware-triage workflow that writes local reports and keeps higher-risk actions gated on user request.

Install this skill if you want a REMnux-focused malware triage assistant. Expect it to read user-supplied samples and create report files in /home/remnux/files/output; review any proposed dynamic execution or detonation step before approving it.

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

Finding
The skill instructs the agent to write a markdown report under a fixed filesystem path, which is a file-write operation affecting the user's system. While the behavior is operationally clear, the markdown description does not explicitly warn the user that the skill will create output files on disk.
