The 'date-uuid' npm package versions 1.0.0 and 1.0.1 is a malicious package that, when required or imported, automatically runs a function that reads specific lines from the README.md file in the current working directory. It uses these lines to reconstruct a base64-encoded URL, fetches a payload script from this URL, writes it to the operating system's temporary directory with a '.vbs' extension (obfuscated by splitting the extension string), and executes it via child_process.exec. This design decouples the malicious payload source from the package itself, enabling dynamic and deniable deployment of malicious code. The obfuscation and execution behavior indicate deliberate evasion and malicious intent.

The package executes arbitrary code fetched from an attacker-controlled URL on the victim's system, which can lead to remote code execution and compromise of the host environment. Because the payload URL is sourced from the caller's README.md file, the attack can be staged or changed without republishing the package, increasing the risk of undetected ongoing compromise.

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 environment and replace them with trusted alternatives. Monitor your environment for any execution of unexpected scripts and verify the integrity of your dependencies. Since this is a malicious package, do not rely on vendor advisories for remediation; instead, remove the package and audit affected systems.
