The package ships a preinstall hook (node poc.js || true) that runs on every npm install. poc.js collects host fingerprint data (hostname, username, os.platform(), network configuration via ipconfig/ip a/resolv.conf, id, whoami), the parent project's package.json, git remote URLs, CI workflow files, and bulk-scrapes process.env for any key matching a hardcoded prefix list (TOKEN, AWS, AZURE, NPM, GITHUB, GITLAB, JENKINS, CI_, WALMART, WMT, etc.). The collected JSON is POSTed over HTTPS to a hardcoded Interactsh out-of-band collector (d8acb4hon5btn99s9lsgakhs31dmwk9cr.oast.pro) plus a DNS callback to the same host. The package name and the inclusion of WALMART/WMT in the env-var harvest list indicate this is dependency-confusion bait targeting Walmart's internal @xarc/* scope; package.json self-describes it as 'authorized dependency confusion testing' but ships with no authorization gate, so any installer that resolves this name has its CI/CD tokens, cloud credentials, and source metadata shipped to the attacker-controlled OOB host.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
