In this campaign, specific versions of involved affected packages hide malicious actions. The malicious code is hidden in specific versions of a dependency (is-it-ai), intentionally pinned by specific versions of dependent packages. All package versions were uploaded with malicious intention; the ones without malicious references are clearly intendent only to hide a cover for the rest. When triggered, the malicious action fingerprints the environment and contacts the remote server. If it responds with an URL, it will be downloaded and executed.
