####################################### DISCLAIMER ########################################
| Memcrashed is a tool that allows you to use Shodan.io to obtain hundreds of vulnerable |
| memcached servers. It then allows you to use the same servers to launch widespread |
| distributed denial of service attacks by forging UDP packets sourced to your victim. |
| Default payload includes the memcached "stats" command, 10 bytes to send, but the reply |
| is between 1,500 bytes up to hundreds of kilobytes. Please use this tool responsibly. |
| I am NOT responsible for any damages caused or any crimes committed by using this tool. |
