VNC password cracker - VNCcrack

VNCcrack is a fast offline password cracker for the VNC challenge/response protocol. If one can somehow observe a VNC authentication, then VNCcrack can run a dictionary attack against the exchange and attempt to find the password.

It works by scanning a pcap file (as generated by the common tcpdump tool) for VNC challenge/response exchanges, then checks against a preexisting wordlist

Installation
The Botan and pcap libraries are required.

After having downloaded and decompressed the tgz file there's only to:

        $ cd VNCcrack-2.1
        $ ./configure
        $ make
        $ su -c "make install"
