NAME

       Yersinia - A Framework for layer 2 attacks

SYNOPSIS

       yersinia [-hVGIDd] [-l logfile] [-c conffile] protocol [-M] [protocol_options]

DESCRIPTION

       yersinia  is a framework for performing layer 2 attacks. The following protocols have been
       implemented in Yersinia current version:  Spanning  Tree  Protocol  (STP),  VLAN  Trunking
       Protocol  (VTP), Hot Standby Router Protocol (HSRP), Dynamic Trunking Protocol (DTP), IEEE
       802.1Q, IEEE 802.1X, Cisco Discovery Protocol (CDP), Dynamic Host  Configuration  Protocol
       (DHCP), Inter-Switch Link Protocol (ISL) and MultiProtocol Label Switching (MPLS).

       Some  of the attacks implemented will cause a DoS in a network, other will help to perform
       any other more advanced attack, or both. In addition, some of them will be first  released
       to the public since there isn't any public implementation.

       Yersinia  will  definitely help both pen-testers and network administrators in their daily
       tasks.

       Some of the mentioned attacks are DoS attacks,  so  TAKE  CARE  about  what  you're  doing
       because you can convert your network into an UNSTABLE one.

       A  lot  of  examples  are  given  at this page EXAMPLES section, showing a real and useful
       program execution.

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.

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 and enjoy your session :)

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 (specially useful for Windows users).

EXAMPLES

       -  Send  a  Rapid  Spanning-Tree  BPDU  with  port  role designated, port state agreement,
       learning and port id 0x3000 to eth1:

       yersinia stp -attack 0 -version 2 -flags 5c -portid 3000 -interface eth1

       - Start a Spanning-Tree nonDoS root claiming attack in  the  first  nonloopback  interface
       (keep in mind that this kind of attack will use the first BPDU on the network interface to
       fill in the BPDU fields properly):

       yersinia stp -attack 4

       - Start a Spanning-Tree DoS attack sending TCN  BPDUs  in  the  eth0  interface  with  MAC
       address 66:66:66:66:66:66:

       yersinia stp -attack 3 -source 66:66:66:66:66:66
