--- _-= Per source details.

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.
