Details

The package core-js version 3.47.0 is not classified as malware. The only evidence is a low-confidence YARA rule match (js_hex_obfuscation) in package/modules/es.data-view.set-float16.js. While hex obfuscation can be a technique used in malicious code, it is also used in legitimate JavaScript code for various reasons, such as code compression or protection. Without stronger evidence, it's not possible to classify this package as malware.
