The 'mddriver' npm package versions 1.8.1, 1.8.2, 1.8.3, 1.8.4, 1.8.5, and 1.8.6 contain malicious code that, upon requiring the package, executes an immediately invoked function expression (IIFE) that fetches base64-encoded JSON from an anonymous paste host. The content field of the fetched JSON is executed via a Function constructor, allowing arbitrary code execution controlled by the attacker. The package is a typosquat targeting developers searching for legitimate MongoDB drivers, with the shipped code being a copy of Node's built-in 'path' module plus the malicious dropper. This results in full compromise of any system running the package.

Any system with the affected 'mddriver' package installed or running is fully compromised, as the package executes arbitrary code fetched from an attacker-controlled source. This can lead to unauthorized access, data theft, and persistent malicious control. All secrets and keys on the compromised system should be considered exposed and must be rotated from a secure environment. Removal of the package does not guarantee removal of all malicious artifacts or backdoors.

No official patch or fix is available. Immediate removal of the 'mddriver' package is required. All secrets, credentials, and keys stored on the compromised system must be rotated from a different, secure computer. Due to the high risk of full system compromise, consider rebuilding the affected systems from trusted backups or reinstalling the operating system to ensure complete eradication of malicious code.
