Did you miss the link here (http://bitcointalk.org/index.php?topic=93074.0)? It's in the first post.

Here you go : http://pastebin.com/AMrABK66The good thing is that what genjix posted contains a full git repository, meaning we see can all the different ToS versions.

I wonder what insights we will gain from seeing under the hood just how exactly did Bitcoinca operate, it might turn out that the attack was actually a good thing and it stopped a bucket shop scam where people were unfairly losing loads of money vs the house. Of course there's no question the loss for everyone who had their funds there is very unfortunate and regrettable and wrong.

Not one test in the whole codebase. Title: Re: BRB, reverse-engineering Bitcoinica Post by: rjk on July 13, 2012, 04:59:00 PM Just had a quick look. "I am a god-level programmer and every line that I write turns to gold and bows down at my feet. Unit tests? What an insult!" :-\Not one test in the whole codebase. Title: Re: BRB, reverse-engineering Bitcoinica Post by: paulie_w on July 13, 2012, 06:49:43 PM Just had a quick look. Not one test in the whole codebase. aren't unit tests a default part of rails these days? or is that some other kind of test? Title: Re: BRB, reverse-engineering Bitcoinica Post by: davout on July 13, 2012, 07:05:17 PM Just had a quick look. You can't judge an app on that, tests mean you're protecting yourself against regressions.Not one test in the whole codebase. The app was written in 4 days, I think it is an impressive piece of work despite a couple major security flaws I identified by simply having a quick look. aren't unit tests a default part of rails these days? Rails gives you the infrastructure to easily write them since day one. But they don't just write themselves :)or is that some other kind of test? The real facepalm flaw is the fact that production passwords are stored in the code itself. This is plain wrong. You're effectively giving the github (or whatever source control system you use) access to all funds at all times. And it's fucking trivial to get right, just make a deploy hook to copy the production configuration files from the production server, to the production server.

It would be pointless to write this in the wiki, all the Rails security basics are widely available online.If you want your app to be secure it's not the lack of information that's in the way. Title: Re: BRB, reverse-engineering Bitcoinica Post by: davout on July 13, 2012, 07:52:16 PM Additionally the app itself has never been hacked (which is a little surprising :D)
Title: Re: BRB, reverse-engineering Bitcoinica Post by: hazek on July 13, 2012, 08:10:53 PM Could you in layman's terms explain what the app actually does in terms of positions and matching and liquidating, ect...

I haven't gotten there yet.Took a bit of time to get every moving part in place to have it actually running. Title: Re: BRB, reverse-engineering Bitcoinica Post by: hazek on July 13, 2012, 08:28:16 PM Cool, I can't wait to hear how it really worked.

I haven't gotten there yet.Took a bit of time to get every moving part in place to have it actually running. can you talk a bit about that? i assume there's no easy install of all dependencies listed neatly in a Gemfile? i would like to know how the app interfaces with the local bitcoin client or client(s). Title: Re: BRB, reverse-engineering Bitcoinica Post by: davout on July 13, 2012, 09:05:02 PM i assume there's no easy install of all dependencies listed neatly in a Gemfile? Your assumption is incorrect :)i would like to know how the app interfaces with the local bitcoin client or client(s). It uses the bitcoiner gem which is my code (extracted from bitcoin-central) packaged by someone I don't know as a ruby gemTitle: Re: BRB, reverse-engineering Bitcoinica Post by: ashleyconnor on July 13, 2012, 10:25:53 PM Could you in layman's terms explain what the app actually does in terms of positions and matching and liquidating, ect... I haven't gotten there yet.Took a bit of time to get every moving part in place to have it actually running. I installed redis but I was getting nilClass errors. I'll give it more time later. |
