"Yersinia is a network tool designed to take advantage of some weaknesses in different network protocols" - http://www.yersinia.net/
I think Yersinia is a pretty cool tool and over the Christmas break I decided to see how easy it is to exploit each of the network protocol it implements.
After installing Yersinia, to run it with the ncurses GUI (which is good for beginners), type:
yersinia -IFrom here you can press "h" to see the options. Basic commands is "g" to select the protocol you want to attack (or use F2 - F9 to click through them). When you are on the protocol page, press "x" to list the available attacks and "l" to list which attacks are currently running.
I'm going to go through each protocol attack and how they work in my subsequent blogs posts. As of writing, in Yersinia v0.7.3 the protocols listed below are implemented. Each protocol will be a link to my blog post with more detail.
Yersinia can be used to test the following protocols on the network:
- Spanning Tree Protocol (STP)
- Cisco Discovery Protocol (CDP)
- Dynamic Trunking Protocol (DTP)
- Dynamic Host Configuration Protocol (DHCP)
