3. Introduction
Computer Emergency Response Team are one of
the main today tool to enhance cyber security.
A CERT have to ensure:
• A centralized coordination for IT security issues
(Trusted Point of Contact)

• Cyberspace monitoring.
• The expertise to support and assist to quickly recover
from security incidents.
• Awareness of all categories of users.
4. Who are Anonymous?
Anonymous is a decentralized network of
individuals focused on promoting access to
information, free speech, and transparency.
The group has made international headlines by
exposing The Church of Scientology,

hacktivist, trying to act anonymously to hack
information systems belonging to freedom
enemies.
6. Tunisian Anonymous
Since the Tunisian operation in January 2011,
Anonymous did not stopped to fascinate young
Tunisian hackers and cyber activist.
Small groups started to be constituted, and may
anonymous initiatives was run to gather all these
groups under the same organization and adopt
the same objectives
Tunisian Anonymous On facebook (About 110k)
{ Elite Attack}
Anonymous TN On facebook (About 20k)
ＡｎｏＮＹｍＯｕｓ On facebook (About 50k)

7. Tunisian anonymous groups: main objectives
Internet freedom (anti-censorship)
Guarding the revolution objectives
• Fighting the old regime
• Investigating on corruption
• Leaking confidential information
Interfering with politics
• They have their own political ideas
• Fight some special political parties
10. The government position
The Minister of ICT announced on the national TV
that the National Information Security Agency and
the Tunisian CERT will be fighting Anonymous: A
declaration of War.
Anonymous reacted by announcing a special
operation against the security Agency
www.ansi.tn on the 28th of April 2012 and
another operation against the government for the

12. The main anonymous attack: dDos
Low Orbit Ion Cannon (loic)
Web Stress Tool.
Can be used in a stand-
alone mode or it can be
synchronized using an IRC
Server.
This software needs to be
installed
14. The main anonymous attack: dDos
With LOIC, Anonymous succeeded to cause a denial of
service on many servers within few minutes
Very strange behaviour to be analyzed
Analysis steps
• Log analysis for a DDoSed servers Surprising
• LOIC traffic analysis
• DoS simulation in lab
• dDos simulation in lab
• Server Analysis
The default configuration of web servers is the problem
• Developing a new tuning and hardening guide for apache
server to resist to such attacks
15. The main anonymous attack: dDos
TCP Connection: Three way handshake
1
Apache
HTTP sessions: GET HTTP 1.0
2
18. The main anonymous attack: dDos
Good news: it cannot be used with proxy
Proxy Server
19. The online LOIC: JS LOIC

24. The defense strategy
The Tunisian CERT was the main coordinator to handle
these attacks.
Activation of the national reaction plan.
Activation of the crisis mode.
Incident coordination:
• With local IS, Telco, and Critical infrastructures.
• With international partners.
Action taken
• Watching hackers and studying their behavior.
• Anticipating attacks.
• Analyzing Millions of log lines and developing blacklist.
• Sharing blacklist.
• Neutralizing IRC servers.
• Securing and Hardening vulnerable servers.
25. Role of the CERT: National coordination
Inform all stakeholders (ISPs, Telcos, Defense,
National Security, Financial Sector, Energy Sector,
…).
Monitor all critical Web Sites, and inform
companies about any abnormal behavior.
In case of attacks, collect and analyses log files.
Identify the list of IPs participating to the attack,
and develop a temporary black-list.
Continuously update the black-list, until the end of
the attack.
26. Role of the CERT: International coordination
The LOIC was synchronized using 3 different IRC
servers (1 in Russia, 2 In USA).
7 IRC server for communication (Canada, 3
Germany, Netherland, Austria)
Taking down theses server will end the attack.
Collaboration with FIRST network and
international partners to take down these servers.
International assistance to mitigate the attack
(exchanging list of IPs to filter).
27. Conclusion
Anonymous is not a common group of hacker:
• They are not hackers but they are a huge number of
activist.
• They do not use very sophisticated hacking
techniques.
• They can be assister by hacking groups (LulzSec,
TeamPoison, …) and also local groups.
Facing anonymous attack, can only be done
through coordination.
Anonymous will be one of the main threat for the
next period:
• Their number is increasing.
• They start to be organized.
• They start to learn hacking and recruit hackers.
