bailian-ai-toolkit

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly scoped Alibaba Cloud Bailian CLI helper with disclosed cloud data sharing and user-consent checks.

Before installing, understand that using the skill can send prompts, URLs, search queries, generated content, and explicitly approved local files to Alibaba Cloud Bailian, and OAuth login may save a session locally. Only use it with files and accounts you are comfortable sending to that service.

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

本目录固定使用 `bailian-cli@1.26.0`，传递依赖由 `package-lock.json` 锁定。不要全局安装，不要运行远程安装脚本，也不要调用内置自更新命令。

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
