HIGH New obfuscated file: dist/assets/main-BIk8ZPG8.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

HIGH New file with network + code execution: dist/assets/polyfill-ZEo_y4cE.js source-diff

Newly added file contains both network calls and dynamic code execution. This is a hallmark of dropper/loader malware.
