supply-chain-guard 0.1.1

A lightweight OS-level supply chain attack guard for Python

chain_guard

🛡 Features

• Import Interception: Blocks unauthorized access to sensitive environment variables (e.g., AWS_SECRET_ACCESS_KEY, DATABASE_URL) during package initialization.
• File System Guard: Prevents third-party packages from reading sensitive files like ~/.ssh/id_rsa or ~/.aws/credentials.
• OS-level Telemetry & Execution Prevention: Uses Python's native Audit Hooks (PEP 578) to actively block remote code execution (os.system, subprocess) and reverse shell network connections (socket.connect) at the moment a suspicious package is imported.
