Check whether loader-utils-kit is in your codebase
Corgea flags malicious and compromised dependencies with reachability analysis, so you fix the packages that actually run in your application instead of working through the whole lockfile.
Description
loader-utils-kit ships lib/contract.js, byte-identical to the pino-testkit payload: an obfuscated module that decodes and evaluates code at load. It is a new name for the pino-testkit (MAL-2026-16484) campaign; the file hashes below match that record's evidence. The package presents itself as an ordinary utility, so the code runs on import or install without the user knowing.
