The package's install lifecycle script runs node index.js, which loads runtime/support/telemetry/probe/impl.js. On every npm install, that module dynamically resolves the os and dns core modules via module.constructor._load with char-code-obfuscated names, reads os.userInfo().username, os.hostname(), and the basename of process.cwd(), and encodes them as DNS labels in a dns.resolve4 query to oob.algamil7x.xyz. The destination domain is reconstructed at runtime from a hex char-code array in runtime/support/telemetry/probe/d4c8a1.js / e5d9b2.js rather than appearing as a plain string. The combination of an install-time hook, obfuscated core-module loading, obfuscated destination, and DNS-tunnel encoding of installer identity fields is a classic install-time exfiltration beacon.

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.
