The primary purpose of whisker is to be a URL scanner, which is used to search for known vulnerable CGIs on websites. Whisker does this by both scanning the CGIs directly as well as crawling the website in order to determine what CGIs are already currently in use.
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.
