Analysis

@servicetitan/forge@0.5.5 is a trojanized React component library. Its preinstall hook (setup.mjs) downloads a Bun runtime binary and uses it to execute a 727KB heavily-obfuscated JavaScript file (math_init.js) at install time. The package also depends on known-malware packages (@servicetitan/anvil-icon, @servicetitan/anvil-react, @servicetitan/anvil-token), pulling them in as transitive dependencies. The obfuscated payload uses a custom base64 decoder and large constant arrays to conceal its logic.
