Analysis

The package's preinstall hook (setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun and uses it to execute a bundled 727KB obfuscated script (math_init.js) during npm install. The script is obfuscated with a large encoded string array and a custom decoder, so its logic is not readable; it runs automatically on every install. The hook also probes the host (ldd --version, /etc/os-release) to select a platform-specific runtime build before executing the payload.
