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

-= Per source details. Do not edit below this line.=-

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.
