Malicious code in cbr-internal-utils (npm)

On module load, the package's main entrypoint shells out via child_process.exec to run cat /etc/passwd and prints the contents to stdout. This fires unconditionally when any consumer require()s the package — no user action or configuration is needed. The package has an internal-sounding name and empty author/description metadata, consistent with a dependency-confusion probe or reconnaissance payload rather than a legitimate library. Reading /etc/passwd serves no library purpose and enumerates local user accounts on the installer's host.
