Alibaba Supplier Outreach

Security checks for vulnerabilities and agentic risk

Overview

This skill automates Alibaba supplier outreach, but its sensitive actions are aligned with that purpose and gated by user selection and message approval.

Before installing, understand that this skill can use your logged-in Alibaba session to read messages and send supplier inquiries or replies after approval. It also keeps local negotiation notes in ~/.claude/supplier-conversations, so avoid using it on shared machines or delete those logs if they contain sensitive pricing or supplier information.

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

Vague Triggers

Medium
Confidence
89% confidence
Finding
The trigger phrases are broad enough that ordinary user input like a product name or casual mention of follow-up could activate messaging or negotiation flows unexpectedly. In a skill that can navigate logged-in sessions and send supplier messages, ambiguous activation increases the chance of unintended external actions.

Vague Triggers

Medium
Confidence
90% confidence
Finding
Treating a bare product keyword as sufficient to enter OUTREACH mode is risky because a minimal prompt can start a workflow that researches suppliers and prepares communications. In this context, the skill operates on a logged-in Alibaba session and can progress toward contacting third parties, so ambiguous activation is materially more dangerous than in a read-only skill.

Confidence
60% 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.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The skill directs persistent local storage of supplier names, message content, pricing targets, and negotiation history without notifying the user or obtaining consent. This creates privacy and data-governance risk, especially on shared machines or environments where local files may be backed up, synced, or accessed by other tools.

Intent-Code Divergence

Medium
Confidence
95% confidence
Finding
The rules section states 'Always show messages to user before sending — never auto-send,' which communicates a no-auto-send policy for all messages. However, the outreach workflow tells the operator to show the message for approval and then proceed through automated send steps, creating a direct contradiction between documented intent and prescribed behavior.
