macOS Automator Services

Security checks for vulnerabilities and agentic risk

Overview

The skill is not clearly malicious, but it needs review because it claims to install macOS Automator services whose workflow files are not included and its install/uninstall guidance can affect persistent user services.

Review before installing. This package does not include the workflow files it tells you to copy, so you cannot verify or install the advertised services from the artifact as published. If a complete package is provided later, inspect the workflow scripts first, back up ~/Library/Services, avoid broad chmod commands, and delete only workflows you confirmed came from this skill.

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

Tool Parameter Abuse

Tool Misuse
Confidence
91% confidence
Finding

This finding points to the same destructive uninstall command instance: a forced recursive delete of a workflow bundle in the user's service directory. In context it is not overtly malicious, but it normalizes unsafe deletion practices and can cause accidental removal or unrecoverable loss if used incorrectly.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The install and uninstall guidance tells users to copy and delete workflow bundles directly in ~/Library/Services without any backup, overwrite check, or ownership validation. This can clobber existing similarly named services or remove user-customized workflows, causing unintended loss of functionality or user data within those workflow bundles.

Content

No source excerpt is available for this finding.

File System Enumeration

Medium
Category
Data Exfiltration
Confidence
60% confidence
Finding

Code scans file system directories looking for sensitive files. This could be reconnaissance for credential theft.

Content

cp -r assets/*.workflow ~/Library/Services/

验证安装

ls -la ~/Library/Services/

Session Persistence

Medium
Category
Rogue Agent
Confidence
75% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
77% confidence
Finding

The manifest-style description and the rest of the document present the skill entirely in Chinese, but do not state that it is intended only for Chinese-speaking users or offer any language choice. Under the policy, forcing a specific language without opt-in can be a natural-language policy concern unless the locale restriction is documented and justified.
