What is the event all about?

Computer security?

Information security?

Cyber Security?

Is it a game?

Are we going to learn hacking?

2. How modern operating system work and system administration.

3. Application/Database/Service how they designed and work.

Penetration testingPenetration testing methodology

• Information Gathering/Reconnaissance

• Scanning/Enumeration

• Vulnerability Identification

• Exploitation

• Report

14

Tools and tactics

• Do not reinvent the wheel…Use existing tools

• But do not just depends on Tools/Scripts…In some case you have to write your own

Ok enough ! Can you please tell me what I need to do

today?

WE DO NOT HAVE ANY PREPARATION

Questions.1. A question from cryptography.  (300

points)

2. A question from malware analysis. (not that much hardcore as it sound) (150 points) 

3. A forensic analysis ( The easiest question of the contest) (50 points)

46

Final Questions.

1. A server named GetRoot_v00t  will be given. (500 points)

2. Another server named GetRoot_Drag0n will be given. (1000 points)

Both server is taken down from live, because it is suspected as compromised by attacker and the attacker changed its root password. So your job is to recover the root access of those server as well as create a report of what venerability those server has to the judges.

47

Rules• You must run the given Virtual machine only in NATed mode.

• Take Screenshots in each success steps include them to a document.

• You can ask judge for clue to solve a problem with sacrificing some point(s). It's will be totally depending on judge how much point he will deduct for the clue before he give the clue he will tell you how much point will be deducted. This rule because this type contest is new will not be available in future.

•  You are suppose to work with given machine(vmware), Any type of activity that might be destructive for lab setup or host machine or any type of  destructive activity using lab internet is strictly forbidden. If any team do such activity, the team  cannot continue the contest anymore also IUT will take legal action about such activity.

• You should stay around your work station until it not require to move.
