Malicious code in @innocarpe/deepseek-build (npm)

The npm package's postinstall script (scripts/postinstall.js) requires child_process and issues POST requests carrying environment and host identifier data at install time. Installing the package causes automatic outbound network activity from a lifecycle hook that reads local process state, matching the shape of an install-time credential/host reconnaissance beacon rather than a documented build step.
CWE
- CWE-506 - The product contains code that appears to be malicious in nature.
