Cheops is a GUI-based network-mapping tool that is quite useful in developing a visual layout of the target network. We prefer to develop network maps of our targets to provide a visual picture of the network topology so we can understand the path traffic follows from the source machine through the Internet and on to the target hosts. In addition, it is beneficial to have a network map to present to organizations since companies often want to compare it to their own maps of the network.
Usage The command to bring up the Cheops GUI is simply:
On launching the program, the user is given the option to map the current network. It is a good idea to select this option so that the network path from your present location to the target domain can be traced out. However, this is not a necessary step. You can directly map the client’s network by selecting the Add Network option from the Viewspace tab on the pull-down menu. A window will appear in which the network and the subnet mask can be identified.
Cheops uses icons to represent individual hosts identified and detected on the target network. For example, a red devil is used to depict the BSD operating system. Penguin for a Linux box.
Cheops can present additional information on the individual host: running the cursor over the item shows the host’s name (if found), IP address, and OS. As mentioned, QueSO is used to perform the OS detection.
In addition, right-clicking on an icon makes available additional tools, including Traceroute, Ping, Scan, and Monitoring functions. The Traceroute and Ping options run their respective UNIX command line tools. The Scan option performs a rudimentary scan of the hosts. The Detect option presents the window that is shown when the left mouse button is clicked. The Monitoring option allows the user to monitor the host for Web, mail, FTP, and other servers.
A reverse DNS option is also available under the Viewspace tab. This process reveals the host name of identified hosts.
In our use, we mainly employ Cheops for its mapping functions, although having additional functionality, such as OS detection, is very helpful. Other tools in our tool kit are used for additional functionality, such as Nmap for port scanning and VisualRoute for a traceroute.Hacking Tools
