pump-segments-sdk @20.1.1

Summary

package.json declares a postinstall hook that runs index.js on install. The script collects the installer's hostname, full process.env, platform info, output of whoami/uname/id/ps aux, cwd, package.json, node_modules listing, /etc/passwd, /etc/shadow, ~/.npmrc, and ~/.npm/_logs, and POSTs the collected data over plain HTTP to a hardcoded oastify.com (Burp Collaborator) subdomain. The package presents itself as a netbsd-x64 esbuild build, which does not match the observed behavior. The read of ~/.npmrc exposes any npm auth tokens present on the installer host, and /etc/shadow read attempts to exfiltrate local password hashes.
