Hello,

I am busy with an challenge and i try to learn to work with wireshark. I have an capturefile where i isolated this peace from : http://www.cloudshark.org/captures/11462ea19f2b

Here i found an address to the Command and Control interface of the botnet. Question: is this the client-controller or is this the botnet master (server).

How do i recognize a client-controller?

Greetings,

kweerd.

Question: How can i find this password in the capture file...?

Hi,

I am not sure I understand your question - it seems that its client-server communication. What exactly are you looking for?

My question is: How can i connect to that Client controller and stop it?

(03 Jan '14, 22:16) kweerd63

kweerd63, I am also working on this challenge. How did you get that IP address?

Hi Kurt,

It's a challenge from my office.

I have to find an client controller in a pcap file. I have been searching a while now and i think i know the ip number that has something to do with it, but i don't know how to go further now.

The pcap file is about 80 Mb.

Best regards.

It's a challenge from my office.

and you two work in the same office !?!

I have to find an client controller in a pcap file.

unless you know the botnet and how the protocol works, all you can do is browse through the frames until you find something 'suspicious'.

(08 Jan '14, 07:37) Kurt Knochner ♦

Hello Kurt,

I found different suspicious things, but i don't know what to do with it. I think i go to some course to learn more about network traffic.

Best regards,

kweerd63

Can you send me a mail how you found the client controller??? I also found the command & controll interface but not the client itself??

You can search in the pcap on:

tcp.port==443 -->> botnet uses ssl connections

htttp.request.uri contains "login"

Thanks,

But i tried that already. Nothing that looks like an logon or login.

I think i give up.

I did a lot of searching, decrypting and find a lot of clues,but i don't know how to finish this part. I see a lot of suspicious data. (Javascripts, perl programs, ....) but i don't see the clue to give the right answer to this contest.

Best Regards,

Can you post the capture file somewhere?

(08 Jan '14, 13:41) Kurt Knochner ♦
(08 Jan '14, 13:53) kweerd63

O.K. the content of the capture file leads to this web site

https://www.certifiedsecure.com/

Apparently there are 'hacking' challenges you need to pass to get some sort of certification and the guys here probably thought it might be easier to ask other people than to use their own brain, which is kind of lame ;-)

(09 Jan '14, 16:04) Kurt Knochner ♦

And how does this work with that searching etc???

I've searched and searched.. typed several ip's but or it's a normal site or it doesn't shows anything?

How doe i recognize if i'm on the wright botnet site???

searching only works if you know exactly what to look for, which isn't the case for an unknown botnet protocol. So, all you can do: browse through the frames and try to find something 'suspicious'.

(08 Jan '14, 15:38) Kurt Knochner ♦

Hi,

Did you find the "command and control client interface"?

Or did you found something else?

O.K. guys, would you please post some information about this 'challenge'!

This is not a forum for chats, this is a Q&A site. Please read the FAQ for more info.

The nature of the posting on this question, i.e. comments as answers and the distinct lack of actual answers and the minimal Wireshark relevant content is making me want to close this question.

sorry grahamd. Please don't close this question yet.

We found certain data with wireshark but we don't know what to do with it and need some help.

@kurt May i ask for your help and mail you some of the data stream? Maybe you can tel me something about it.

(09 Jan '14, 02:45) zyar

please post some information about this 'challenge'. Apparently you are all talking about the same thing and if you want further help, we need more information. And no, I'm not going to answer questions via e-mail or on the phone!
