  1. <h1>DoS Level 3</h1>
  2. <p>The router in this level responds to a special type of ping, called a "Broadcast ping". When a router receives a packet that is addressed
  3. to the broadcast address, it replicates it and sends it to <em>all</em> the machines on the network.
  4. <p>In this level, Google has received an <strong>upgrade</strong>: it can no longer be DoS'd from a single computer.
  5. Multiple computers will be required to coordinate with each other in order to send enough traffic.
  6. <p>However, you only have control of a single computer! You will have to implement a <strong>smurf attack</strong>. In a smurf attack, you leverage
  7. other devices to send traffic <em>for you</em>.
  8. <p>Experiment with sending broadcast pings by sending a message with the dstip set to "Broadcast".
  9. See if you can overwhelm Google by combining this with what you learned about spoofing packet source addresses.
  10. <h3>Level Objectives</h3>
  11. <ul>
  12. <li>Send a ping to the IP <strong>Broadcast</strong></li>
  13. <li>Can you get Barbara to send a packet to Google?</li>
  14. <li>Overwhelm Google with traffic</li>
  15. <li>Try to do this with only one packet in the Editor! (you may use the "repeat" feature)
