snallygaster is a tool that looks for files accessible on web servers that shouldn't be public and can pose a security risk. Typical examples include publicly accessible git repositories, backup files potentially containing passwords or database dumps. In addition it contains a few checks for other security vulnerabilities.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
