Analysis
The package runs a preinstall hook (setup.mjs) that downloads the Bun runtime from github[.]com/oven-sh/bun and uses it to execute a 727KB obfuscated payload bundled as math_init.js. The payload is encoded with a custom base64-variant decoder and a large encoded string array, concealing its behaviour. The package also depends on @or-sdk/sdk-api, a package previously identified as malicious. Installing this package executes the obfuscated payload at install time.
