We continuously do a lot of Internal Network Penetration Tests for our clients. Many a time we're given permission to put a machine into their network and test the attack surface area from that machine. During these times its extremely helpful to understand the other valid network ranges that are present. With the help of a combination of many open source tools its definitely possible to do the same. However doing so and correlating the output of all of those tools is at times..time consuming.
So we thought of writing a small tool to automate the same. Since there's nothing proprietary that we used at all , we thought it'd be a good idea to get feedback from the Open Source community about how we can improve it. With that in mind we've hosted the tool on Sourceforge.
Do try it out and let us know how we can improve. All types of feedback is most welcome.
