The is-it-ai package on PyPI contains malicious code in specific versions (0.1.0, 0.1.1, 0.1.3) that, when triggered, fingerprints the environment and contacts a remote server. If the server responds with a URL, the package downloads and executes a remote executable. This behavior is part of a targeted attack campaign involving intentional inclusion of malicious code in a dependency, designed to hide malicious actions behind legitimate package versions.
