Welcome to LQ, hope you like it here.
Not knowing what software is installed does not automagically equal your server being "cracked": you simply want to know what software is installed. Start by checking the Apple web site support section for the manuals for your product as they will list the applications that come installed with OS X / IOS. Then check the Apple store for other product names. Additionally use your favorite search engine as CUPS, SSHd, SNMP ("trap receiver"), TWAIN, OpenGL and Apache are commonly used technology / application identifiers.
