# DoS Level 3

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 to the broadcast address, it replicates it and sends it to all the machines on the network.

In this level, Google has received an upgrade: it can no longer be DoS'd from a single computer. Multiple computers will be required to coordinate with each other in order to send enough traffic.

However, you only have control of a single computer! You will have to implement a smurf attack. In a smurf attack, you leverage other devices to send traffic for you.

Experiment with sending broadcast pings by sending a message with the dstip set to "Broadcast". See if you can overwhelm Google by combining this with what you learned about spoofing packet source addresses.

### Level Objectives

- Send a ping to the IP Broadcast
- Can you get Barbara to send a packet to Google?
- Overwhelm Google with traffic
- Try to do this with only one packet in the Editor! (you may use the "repeat" feature)
