s0rc3r3r – Sept. 21, 2017, 4:31 p.m.

Can you tell me the IRC Channel for this CTF?


slenderestman – Sept. 21, 2017, 4:50 p.m.

jkrshnmenon – Sept. 21, 2017, 4:55 p.m.

ishank011 – Sept. 21, 2017, 6:30 p.m.

Hello everybody. We have upgraded our AWS EC2 instance to m4.16xlarge, which is the highest configuration that AWS offers as part of its EC2 series. However, we're still experiencing issues as serving the Javascript is taking a lot of time. We realize that the webpage loading is quite slow, but the participants are still able to submit flags and there is fierce competition going on at the top of the leaderboard.

So I request you to bear with us and try to solve the challenges. We deeply regret the inconvenience caused.

Thank you.


slenderestman – Sept. 21, 2017, 9:42 p.m.

lol my computer is terrible its so laggy on the site


mjurinic – Sept. 21, 2017, 9:56 p.m.

irc channel or something?


frodan – Sept. 22, 2017, 3:49 a.m.

omg, I can't login and no recovery func.


akrotos – Sept. 22, 2017, 4 a.m.

Is there an IRC channel? The south Africa challenge is not working. The link goes to.
http://13.126.83.119:9879

The gameboard interface is so slow it's almost unusable. Can anything be done about that?


Griboedoff – Sept. 22, 2017, 5:06 a.m.

I'm starting to believe in Indian programmers mems


jkrshnmenon – Sept. 22, 2017, 5:13 a.m.

I already know how much I'm gonna rate this CTF


0xACB – Sept. 22, 2017, 7:28 a.m.

some services are down

WangYihang – Sept. 22, 2017, 8:37 a.m.

cannot sign in yet...why the server is so slow...


merrychap – Sept. 22, 2017, 8:40 a.m.

We can't solve misc challenge because of your crazy server :c


0palash0 – Sept. 22, 2017, 9:46 a.m.

@Griboedoff not all Indians are same. Please don't make this a stereotype.


Griboedoff – Sept. 22, 2017, 10:10 a.m.

@0palash06 I'm drinking vodka and hanging out with my bear instead of solving tasks. So no stereotypes.


illustris – Sept. 22, 2017, 12:15 p.m.

You should have tested the platform well before using it. We considered using it for BITSCTF last year, but a simple load test with 50 people made it crawl on a fairly powerful VPS


illustris – Sept. 22, 2017, 12:17 p.m.

Also, I think the Japan challenge is broken. It won't accept quark (http://bits-quark.org/) as the answer :P


chq-matteo – Sept. 22, 2017, 1:23 p.m.

@ishank011 @0palash06 can you check China?

Entire system is trash. Impossible to register, log in or do anything.
Taken me ~200 tries over 24h to register a team and account. Finally being able to register a team, i think, and the entire login to the system is shut down.

Get your shit together guys, this is ridiculous.

when is the ranking coming out?

About exploitation 300: It was an easy challenge but the flag format was ambiguous: "The flag is flag{md5 of the integer value of the pass concatenated}"
Why not just flag{md5(password).hexdigest()}? The flag they had on the server was probably wrong, we tried too many MD5 hashes according to different interpretations...
My suggestion for a next edition is: IRC. Some services were down and there was no way to report it.

I'm wonder what is solution of Mongolia Task (Secret Society). Any of X-Forwarded(-For), ip-client, and more of this headers did not give any result...I agree, server was overload, but challenges were exited :) and GUI was amazing :)

@qth007 I'm wondering the same, man.


simonepri – Sept. 22, 2017, 7:51 p.m.

@ishank011 Any news about the final rankings ?


simonepri – Sept. 22, 2017, 8:52 p.m.

I'm not a fan of the UI, especially under heavy loads the entire site was unusable.


Pyhscript – Sept. 23, 2017, 6:38 a.m.

will final rankings be published on ctftime?


Ghaaf – Sept. 23, 2017, 8:53 a.m.

I've never seen such a bad CTF as this one! No support, guessable, wrong flag format !!


andreafioraldi – Sept. 23, 2017, 11:12 a.m.

@Pyhscript good question


ishank011 – Sept. 23, 2017, 8:52 p.m.

Hello all. We apologize for the inconvenience caused to you. We are looking to get the ranklist published on CTFTime soon.
We had not known that the platform would have taken so much bandwidth to get served properly. We request you to bear with us.
Thank you.

Was China buggy? Did you forget to implement diagonal moves?


tylerkerr – Sept. 25, 2017, 2:34 p.m.

Did anyone solve Russia (the modular multiplication/prime sieve crypto challenge)? It was hard submitting flags, but it also seemed like something was wrong with the challenge. If nobody solved it, I'd appreciate a writeup/solution from the challenge creator. Thanks!
