Microsoft Qlib

Security checks for vulnerabilities and agentic risk

Overview

The skill is a straightforward Qlib helper for quantitative finance work, with the main caution that it installs an unpinned Python package.

Install in a virtual environment or container, preferably pin and review the Qlib package version before use, and avoid running the install from a privileged account. The skill itself is coherent and does not request unusual access beyond installing and using Qlib.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

" ``` 3. Store dependencies in a lock file or requirements file containing cryptographic hashes, and install with hash verification: ```bash python -m pip install --require-hashes -r requirements.txt ``` 4. Use a trusted, explicitly configured package index or an internally reviewed artifact repository. 5. Review both the selected package and its transitive dependencies before updating the pinned version. 6. Perform installation in an isolated virtual environment or container under an unprivileged account. 7. Avoid automatic dependency installation where possible; require user confirmation and clearly disclose that installation retrieves and executes third-party package content. ]]>
