Slack

Security checks for vulnerabilities and agentic risk

Overview

This Slack skill is coherent and mostly disclosed, but its fallback setup tells the agent to install a CLI by directly executing a remote installer script without an integrity check or clear user approval.

Before installing, review the OOMOL CLI installer through an official guide, prefer a package-manager or verified release path when available, and do not let the agent run the installer automatically. For Slack write or delete actions, confirm the exact channel, message, file, and payload before execution.

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 install software by piping a remotely fetched script directly into a shell, which is a well-known unsafe pattern. If the remote host, transport, or distribution path is compromised, arbitrary code would execute immediately on the user's machine with the user's privileges; because this appears in a setup section for command recovery, an agent may be more likely to run it automatically after an error.
