The tarball ships only package.json with no code, scripts, main, or bin. The description field contains a ~41KB base64-encoded POSIX shell script that, when decoded and executed, downloads an xmrig cryptominer from gitlab.com/albertotrindade131/al and a github.com/lucas77335/xmrig-amd mirror, installs cron-based persistence, and mines Monero to the hardcoded pool xmr.kryptex.network:8029 with an embedded wallet/worker identifier. Operational strings (pool host, wallet, miner URLs, fallback bare-IP C2 hosts 66.23.199.44, 45.94.31.89, 139.59.59.33, 154.89.152.115, 84.21.173.223, 142.132.131.238) are individually base64-encoded and decoded at runtime via a helper function. The payload script self-references https://registry.npmjs.org/cbc97b7a/latest, indicating the package is designed to be pulled by a companion loader that fetches this metadata and pipes the decoded description to sh, delivering miner installation, persistence, and secondary C2 fetches to the installer.

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.
