The 'date-uuid' npm package (versions 1.0.0 and 1.0.1) is a malicious package that, when required or imported, automatically invokes a function that reads the caller's README.md file to extract encoded URL data. It reconstructs an HTTP URL from base64-encoded fragments, fetches a payload script from this URL, writes it to the operating system's temporary directory as a Visual Basic script file (using string splitting to evade detection), and executes it via child_process.exec. This staged attack mechanism decouples the malicious payload from the package itself, allowing dynamic payload changes without republishing the package. The obfuscation and execution of external code represent deliberate evasion and malicious intent.

This package enables remote code execution on the system importing it by fetching and running an attacker-controlled script. This can lead to full system compromise, data theft, or further malware deployment. The attack is stealthy due to obfuscation and reliance on external payloads, increasing the risk of undetected exploitation.

No official patch or fix is currently available for this malicious package. The recommended mitigation is to avoid using the 'date-uuid' package versions 1.0.0 and 1.0.1. Remove these versions from your projects and replace them with trusted alternatives. Monitor your environment for any execution of unexpected scripts and audit dependencies for malicious code. Since this is a malicious package, do not attempt to use or trust it.
