SideKick is a tool developed to automate the collection of MD5 file signatures. SideKick can be used to collect signatures for files known to be replaced by "rootkits", files with Set-UID or Set-GID permissions in addition to several other collection methods. SideKick can optionally be used with sfpC to automated the collection and processing of MD5 file signatures. SideKick can also be used in a standalone capacity for distributed signature collection. Sidekick can be downloaded here.
