BitSkins

Security checks across malware telemetry and agentic risk

Overview

This BitSkins skill appears purpose-aligned, but it can perform real financial and account-security actions through a broad API helper, so users should review it carefully before installing.

Install only if you intentionally want an agent to operate your BitSkins account. Use the narrowest API key BitSkins allows, keep it in the environment, and require explicit confirmation with exact endpoint, item, amount, destination, and account-security impact before any buy, sell, deposit, withdrawal, API-key, 2FA, trade-link, card, or account-status change.

Finding
The skill invokes a shell helper script to perform API requests, but the skill metadata declares no permissions/capabilities for shell execution. This creates a trust and review gap: a skill that can execute shell commands may be granted more operational power than expected, and if later prompts or parameters are insufficiently constrained, that shell surface can become a path to command injection or unintended local actions.
