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 script (math_init.js) through it. The obfuscated script uses a custom base64-like encoding scheme and contains eval, Function constructor, and child_process references — the actual payload is encoded and only decodes at runtime. The package depends on a known-malicious dependency (@servicetitan/titan-chat-ui-common).
