InCTF'13 [Amrita Cyber Security]

National level Capture the flag contest targeting only for Undergraduate, graduate and post-graduate level students.

This CTF is meant just for learning and getting more good teams from India into world finals in CTF contest.
FYI: CTF means capture the flag.

I would recommend any one interested in computer's to give this CTF a try. They teach you through the process. But yeah! HARD WORK is expected from you. And you should have some programming knowledge. Doesn't matter from which branch/stream of specialisation you are doing. Don't think its meant only for geeks from computer science branch. I'm from Electronics and Communication background still took a respectable position in InCTF'13 --> second position. Even if you are from mechanical background still fascinated about these computer stuff. Then go ahead start off with InCTF.

As i have said earlier InCTF aims more on learning.
This is how InCTF works->

1st round -

  • Purely meant for learning.
  • Designed smartly by the admins/organisers of InCTF, to divide the work between the team members. Everyone can't be good in everything so you got to stick the topics which you choose to take in this round. And become good at it.
  • Topics- Basics of Linux, SQL [ Web Based ], secure programming, Reverse Engineering, Cryptography.
This round is not mandatory but I STRONGLY RECOMMEND to take this round seriously and use it to learn. Because the organisers are ready to help to any time during 1st round.

The tool needed to finish this round successfully is GOOGLE.

2nd round - Jeopardy type.

Qualification round for National level finals i.e main CTF game.

This time they gave us 1 week time duration UNLIKE other CTF's which has 1-2days.
This round is damn interesting because for noobs like US, we need to learn and then use that knowledge to complete the tasks. So utilized this round also for learning.

I saw that many teams where giving up because they had NO CLUE about how to even look at the tasks. Even when we opened the task, we were BLANK. But according to me what you need is just PATIENCE and DETERMINATION. That's all, you can solve 80% of tasks in all categories. What you need is just patience and determination. Any time you can walk into their IRC and query them if you are on your right path for solving a particular task or not.

3rd round - Capture the flag

Time to implement! Time to test what you have learnt!

1st day you will have a mock round, which gives an idea about what to do the next day. Basically aimed at not wasting the time on the contest day. Every minute matters in the finals.

Basically you will have to exploit the different types of services to get the flag.

Your team will be scored/valued on your

  1. Defence - your patching work.
  2. Offence - exploiting other team services and submitting their precious flags :p
  3. Ethical - reporting advisories.
That's all about InCTF.

We participated with the team name r00t. 
Team members-
  • y0g1337h - Yogeesh Seralthan,
  • vn4v1n - Movnavinothan V &
  • x7r0n - Adithya Naresh.
1st round we divided the work and learnt.
2nd round. LANing up is very important. We LANed up in our college hostel [ Amrita School of Engineering ] :p
3rd round. We had awesome fun exploiting services, patching them, and reporting the vulnerabilities.

Thanks for organising such a awesome event -
Arvind S Raj, Seshagiri Prabhu, Bithin Alangot.
