Anonymous developed new type of DDoS?

 

Some evidence is showing that Anonymous developed “Reflective DNS Amplification DDoS” to attack DNS root servers on March 31st 2011.

According to this pastebin post, Anonymous on March 31st, ‘shut down’ the internet by down 13 root DNS servers of the Internet.

A 198.41.0.4
B 192.228.79.201
C 192.33.4.12
D 128.8.10.90
E 192.203.230.10
F 192.5.5.241
G 192.112.36.4
H 128.63.2.53
I 192.36.148.17
J 192.58.128.30
K 193.0.14.129
L 199.7.83.42
M 202.12.27.33

By downing these DNS servers, Anonmyous would have prevented many users from being able to type in a URL such as Google.com to access the specific website.

 

The plan and how it worked:

The principle is simple; a flaw that uses forged UDP packets is to be
used to trigger a rush of DNS queries all redirected and reflected to
those 13 IPs. The flaw is as follow; since the UDP protocol allows it,
we can change the source IP of the sender to our target, thus spoofing
the source of the DNS query.

The DNS server will then respond to that query by sending the answer to
the spoofed IP. Since the answer is always bigger than the query, the
DNS answers will then flood the target ip. It is called an amplified
because we can use small packets to generate large traffic. It is called
reflective because we will not send the queries to the root name servers,
instead, we will use a list of known vulnerable DNS servers which will
attack the root servers for us.

DDoS request —> [Vulnerable DNS Server ] <—> Normal client requests
\
| ( Spoofed UDP requests
| will redirect the answers
| to the root name server )
|
[ 13 root servers ] * BAM

Since the attack will be using static IP addresses, it will not rely
on name server resolution, thus enabling us to keep the attack up even
while the Internet is down. The very fact that nobody will be able to
make new requests to use the Internet will slow down those who will try
to stop the attack. It may only lasts one hour, maybe more, maybe even
a few days. No matter what, it will be global. It will be known.

download link in #opGlobalBlackout

———————————————————————–

The tool is named “ramp” and stands for Reflective Amplification. It is
located in the \ramp\ folder.

———-> Windows users

In order to run “ramp”, you will need to download and install these two
applications;

WINPCAP DRIVER – http://www.winpcap.org/install/default.htm
TOR – http://www.torproject.org/dist/vidalia-bundles/

The Winpcap driver is a standard library and the TOR client is used as
a proxy client for using the TOR network.

It is also recommended to use a VPN, feel free to choose your own flavor
of this.

To launch the tool, just execute “\ramp\launch.bat” and wait. The attack
will start by itself.

———-> Linux users

The “ramp” linux client is located under the \ramp\linux\ folder and
needs a working installation of python and scapy.

We know you wont’ listen. We know you won’t change. We know it’s because
you don’t want to. We know it’s because you like it how it is. You bullied
us into your delusion. We have seen you brutalize harmless old womans who were
protesting for peace. We do not forget because we know you will only use that
to start again. We know your true face. We know you will never stop. Neither
are we. We know.

We are Anonymous.
We are Legion.
We do not Forgive.
We do not Forget.
You know who you are, Expect us.
