Malicious code in @servicetitan/carto-charts-react (npm)

Analysis

The preinstall hook (setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun and then executes a 727KB heavily obfuscated file (math_init.js) through Bun. The obfuscation uses javascript-obfuscator techniques (large _0x identifier arrays, base64 decoding, string splitting) to hide the payload's behaviour from static analysis. The package also depends on @servicetitan/carto-charts-core which ships a matching obfuscated payload.
