This npm package version 20.4.7 includes code in index.js and lib/telemetry.js that downloads platform-specific binaries from dynamically constructed Cloudflare Workers hostnames and fallback DNS TXT records. These binaries are saved to hidden paths with disguised filenames and executed detached via shell commands. The behavior is designed to evade detection by impersonating benign diagnostic artifacts. Installing or requiring this package results in execution of unverified, attacker-controlled binary code, effectively compromising the host system.

Any system with this package installed or running is considered fully compromised. Attackers gain the ability to execute arbitrary code with the privileges of the installer, potentially leading to complete system takeover. All secrets and keys stored on the compromised system should be considered exposed and must be rotated from a secure environment. Removal of the package alone does not guarantee elimination of all malicious components.

Remove the malicious package immediately from any affected systems. Rotate all secrets, credentials, and keys that were stored or accessible on the compromised host from a different, trusted machine. Because the package executes attacker-controlled binaries, assume full system compromise and consider rebuilding the affected systems. No official patch or fix is available for this malicious package; prevention relies on avoiding installation and use.
