How to realize Nuclear bomb-level DDoS attack in Memcache-DRDos

This article introduces you how to achieve nuclear bomb-level DDoS attacks in Memcache-DRDos, the content is very detailed, interested friends can refer to, hope to be helpful to you.

We've all heard of DOS attacks, DDOS attacks, so what is DRDos attacks? R means reflection.

Here we will practice the DDoS attack based on Memcache as the DRDoS reflection amplifier.

Experimental environment:

1. Memcache enables udp snooping

2. Memcache does not enable authentication

Install Memcache first

Install memcached

Start the memcached service. The default port of the memcached service is 11211, which can be customized. Set it to 6666 here.

Start the service

The memcache module of python is needed here. Install it first and install it with pip.

Install python-memcached

First turn on debugging of memcache, then insert some data

Insert Data

Let's take a look at the gap between the generated data and the returned data, and build the request to send it out.

Occurrence data

Server side

You can see that 16 bytes are sent out, but the bytes returned are 1937 bytes

1937T 16x 121.0625

Isn't it big enough? then have a big one.

Occurrence data

Server side

Send 58 bytes and receive 543224 bytes

5432240.58mm 9365.93 times

This one is so powerful, if there are more, the consequences can be imagined.

There are hundreds of thousands of Memcache open in the world.

Repair recommendations:

1. Disable UDP

2. Prohibit access to the public network

3. Enable authorized access
