The mlflow-ui PyPI package versions 2.7.1, 2.7.2, and 2.7.3 are identified as malicious. Upon installation, the package collects local system information and environment variables, probes for connections to common services like databases, and exfiltrates this data. It downloads and executes further malicious code, continuing to exfiltrate credentials and database contents, including SQLite databases. The package also performs network scanning and brute forces other accessible databases, exfiltrating cloud tokens and other sensitive information. This behavior classifies it as an infostealer with dependency confusion characteristics.

Installation of these specific mlflow-ui package versions leads to unauthorized data exfiltration including environment variables, database credentials, SQLite databases, and cloud tokens. The malicious code also performs network reconnaissance and brute forcing of databases, potentially compromising additional systems and data within the environment where the package is installed.

No official patch or remediation is currently documented for this malicious package. Users should avoid installing mlflow-ui versions 2.7.1, 2.7.2, and 2.7.3 from PyPI. Verify package integrity and source before installation. Consider removing these versions if already installed and monitor for suspicious activity related to credential or data exfiltration. Check vendor or PyPI advisories for updates on remediation.
