 ### Malware Blocking
 
-The Aikido Safe Chain works by running a lightweight proxy server that intercepts package downloads from the npm registry and PyPI. When you run npm, npx, yarn, pnpm, pnpx, rush, rushx, bun, bunx, pip, pip3, uv, uvx, poetry or pipx commands, all package downloads are routed through this local proxy, which verifies packages in real-time against **[Aikido Intel - Open Sources Threat Intelligence](https://intel.aikido.dev/?tab=malware)**. If malware is detected in any package (including deep dependencies), the proxy blocks the download before the malicious code reaches your machine.
