Upon finding a vulnerability within a casino's system, I also noticed something else...the casino cheating. http://vimeo.com/110040994 (password: dreamland). Made a video last night demonstrating that even when I can isolate the cards and give myself the best possible scenario, the game will always manufacture a losing situation. Normal game play would never pick this kind of thing up as there are too many card possibilities but since I was able to isolate the cards I wanted, it magnified the cheating. The "cheating code" is probably executed under many different circumstances and games on their site but the video shows it isolated under just one game, bet denomination and bonus round in order to show it at work.
 
That's why bitcoin gambling is getting so big. The reputable websites have "provably fair", and people can calculate & verify the fairness themselves

Very true. Fortunately for me, provably fair casinos still have weaknesses just like any other casino. It's not so much about altering the cards or outcomes of the games, but rather the game functionality and sequence (i.e., using game functions that should be disabled or resetting the entire game to be played again, etc.)
 
First off it's certainly a fascinating find that exploit, so well done.

But it makes sense that systems ''cheat'' in this way. There is very little regulation in online gambling and so while the systems do pay out on occasion, it's always in the houses favor by a steep margin. They can control their profits.

To be fair, real casinos are not far off. The games are always designed in the houses favor - they do have to be winnable but that certainly doesn't mean the odds aren't staked!

Online Casinos are just a seedy bunch - thats why for online gambling I stick to betting on real world events.
 
Nice find OP ! Tho don't mess or submit it there is no point - back in days I was playing around with poker and online roulette and I did reversing on few casino clients ALL were riged (talking about roullete) poker one was not it's people vs people not people vs house.

House always win ! back in day I reported it and got banned and my funds were gone.
 
Wow great find! When you intercept response with fiddler and abort session, is it registered on their server? Can they see that many responses are aborted?
Also did you tried to modify response and directly get #3 without waiting for right card? IF you can send modified response what about putting #2?

BTW this reminds me a bit of this movie: http://www.youtube.com/watch?v=HAz_oUxUuDg

Well I do a lot of different techniques and aborting the session is just one of them. That particular example I call the "Skip." To answer your questions, it may register on their server as an aborted session, but it probably doesn't since it's a side bonus game and their server gives me a new session altogether. I've done techniques where I've played games only using fiddler and was able to play beyond what the interface showed for options. This included depleting the entire deck of cards to isolate the last few (kind of like card counting I suppose) or using game functions well past their intended limits. In some of those instances the casinos were able to see my actions even though I wasn't using the interface at all. But by that time it was already too late for them since the "damage" was already done. That's why forming correct deployment and exit strategies is very important for executing exploits...to catch them when they're not looking.

As for modifying actual game results such as switching the 3 to a 2, well, that's a whole other ballgame and most casinos don't allow that unless they really expose themselves. As such, I came up with techniques that dealt with manipulating game functionality and game structure rather than the cards themselves. A lot of casinos are weak in these areas. The end result is the same...I have the advantage instead of the casino.

That's awesome. Good job bro. I was trying to find a vulnerable website for three hours last night, but to no avail. Do you have any tips on finding sites?
 
And this is why I do not gamble. Unfortunately I don't have the skills to exploit.

I'm sure it must be worthwhile to you if you're willing to waste money like that?
 
I dunno why but this come to me at no surprise, its good to let those who gamble know of this.
 
I read that old ebook you wrote, it was quite of movie like story lol. I despise these parasites very much, but you really went an extra mile or two than an average joe would. Well done.

Its worth it monetary speaking if I find something, lol. But intellectually its always worth it.

Downloads Fiddler, then calls himself Exploit Specialist Extraordinaire LMAO
Even a script kiddie has more sense than to post this stuff on a PUBLIC board.
