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 payload contains eval, Function constructor, and child_process calls. The dist bundles also contain remote-fetch-to-exec capabilities. The package depends on known-malware sibling packages (@servicetitan/titan-chat-ui-anvil2, @servicetitan/titan-chat-ui-common, @servicetitan/titan-chatbot-api).
