Overview
cdn-icon-fetcher is a Malicious package.
Affected versions of this package are vulnerable to Embedded Malicious Code. Once this package is installed and executed, it downloads a Javascript file from a cdn-static-icons.vercel.app URL, which appears to be an image hosting site. However, by using a specific custom header, as described in the library, the JavaScript file is downloaded as a first-stage loader. This loader subsequently downloads a .npl file, which acts as a second-stage loader written in Python. Ultimately, a third Python file, which is the actual payload and referenced in a specific Medium article, is executed.
