Malicious code in @onereach/si-alert (npm)

Analysis
The package's preinstall hook (setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun/releases and executes a 727KB heavily-obfuscated bundle (math_init.js) at install time. The bundle is encoded with a custom string-obfuscation scheme that hides its behavior from static analysis. A Vue UI component has no legitimate need to download a runtime and run an opaque 727KB payload during installation; the payload's actions could not be determined statically.
