## From the sources

Version 0.1.6 contains an obfuscated loader in libs/18.2.0.js. When a website serves this file as a browser script, the injected code decodes and loads https://oomcsn.cc/assets/js/m.js. That remote script loads a beacon and inserts an invisible iframe pointing to https://oomcsn.cc/assets/js/group.html, which selects iOS exploit code based on the visitor's device version. The loader is embedded in a file presented as jQuery and executes when that browser script runs. No npm install-time execution was identified.
