Analysis

@ornikar/renovate-config@9.0.8 is a trojanized version of a legitimate Renovate shared-config package. The preinstall hook (package/setup.mjs) downloads the Bun JavaScript runtime binary from github[.]com/oven-sh/bun/releases/download/bun-v1.3.13/ and executes a 727KB heavily obfuscated JavaScript payload (package/math_init.js) at install time. The payload is obfuscated using the javascript-obfuscator tool, making its runtime behaviour unreadable from static analysis. The package was published from a compromised maintainer account on a package that was previously deprecated and should contain only JSON configuration.
