How To Install And Use Yersinia On Kali Linux

Sometimes you just need an assistant to tell you what are your weaknesses, and how you should react to them. Yersinia is what you need to use the weaknesses in different network protocols. Since network administrations do not usually monitor the LAN unless receiving a problem report, attack occurrence is not surprising and several attacks on Layer 2 protocols could happen (Layer 2 is the second layer of the network, the second layer of OSI protocol). So, you can use Yersinia as a framework for performing layer 2 attacks, analyzes, and tests the deployed network and systems. While it consists of various layer 2 attacks exploiting the weaknesses of different layer-2 protocols, a pentester identifies the vulnerabilities in deep layer 2 of the network which is located in the data link layer like STP and CDP.

Tutorial Install And Use Yersinia On Kali Linux

Yersinia is written in C language and is under the GNU General Public License version 2.0. It is designed to be used for penetration testing and attacks on layer-2 devices such as switches, DHCP servers spanning tree protocols, and so on. Using its GUI, Yersinia is able to make Denial Of Service (DOS) attacks on DHCP simple and easy. Attacks are implemented for some network protocols such as:

  1. Spanning Tree Protocol
  2. Cisco Discovery Protocol
  3. Dynamic Trunking Protocol
  4. Dynamic Host Configuration Protocol
  5. Host Standby Router Protocol
  6. 802.1q
  7. 802.1x
  8. Inter-Switch Link Protocol
  9. VLAN Trunking Protocol

Yersinia Options:

-h, --help [Help screen.]
-V, --Version [Program version.]
-G [Start a graphical GTK session.]
-I, --interactive [Start an interactive ncurses session.]
-D, --daemon [Start the network listener for remote admin (Cisco CLI emulation).]
-d [Enable debug messages.]
-l logfile [Save the current session to the file logfile. If logfile exists, the data will be appended at the end.]
-c  conffile [Read/write configuration variables from/to conffile.]
-M [Disable MAC spoofing.]

GTK GUI

The GTK GUI (-G) is a GTK graphical interface with all of the yersinia powerful features and a professional 'look and feel'.  

NCURSES GUI

The ncurses GUI (-I) is a ncurses (or curses) based console where the user can take advantage of yersinia powerful features.  Press 'h' to display the Help Screen

NETWORK DAEMON

The  Network Daemon (-D) is a telnet based server (ala Cisco mode) that listens by default in port 12000/tcp waiting for incoming  telnet  connections. It supports  a  CLI  similar  to  a  Cisco device where the user (once authenticated) can display different settings and  can  launch  attacks without  having yersinia  running in her own machine (especially useful Windows users).
