Sniffing Flash (Game) communication with Server

Post by Deinos » Thu Jun 16, 2016 6:33 pm

Hi folks,

I'm new here but I hope you might help me. I'm trying to write a bot for a game and for that I need to understand what's happening when I click an object in the game.

I checked here in the forum but all I found is this quite old and not really conclusive thread: Topic-47353

I tried monitoring the traffic but same as my predecessor here, I can't see any communication going on apart from the initial swf downloads. Checked them with SoThink etc with the same lack of enlightenment.
I read that it might have to do with RTMP packets in this thread:
http://stackoverflow.com/questions/1321 ... n-in-flash

But I'm quite new in handling wireshark and I'm not sure if this would be the solution to my problem either.

So I'm hoping someone who knows about how flash client-server communication works, what part is simply client-computed eyecandy and what part is the actual signal send through the action of clicking.

In short I'd be happy if there is someone who could explain to me how flash works or at least gives me hints on deciphering the communication.

Thank you!
Deinos

I don't know what game you're targeting, but assuming it is doing any communicating, you will be able to see it with wireshark. The real question is; will you be able to see anything useful? And as far as I'm aware this depends very much on the flash game itself, so it's very much a case of "try it and hope for the best".

I'd also recommend doing this in a very clean VM or a computer that's doing absolutely nothing else, since running wireshark on desktop pc under normal usage captures everything going over your network interface, which is lots and lots of packets, making it very time consuming if you don't know exactly what you're looking for already.

I'm not sure off hand if the chrome developer tools will show you any information about what's going on, but if it does it'll be the easiest way by far to get some insight into what's going on.

Failing that something like burp suite or ZAP should be able to tell you whatever requests are being made.
