stole games reading bytecode

**Incrue** · 02-18-2006, 10:01 AM

I know its possible in theory, but in the real world how many games are stolen AFTER you put some obfuscation in the swf?I mean, they stolen only cos they could read the bytecode?
Does anyone have one real example of it?

Games stolen from binary files is one thing, but swf files are far from byte code

there's quite a few swf decoders out there that will show you every part of the movie and code, and even recreate the .fla

what kind of 'obfuscation' were you thinking about (other than password protecting which doesn't do much anyway...)?

I think he's asking, how many of these theives bother to hack SWFs.
I'd say a majority don't bother.

Had to approach a site ( I'm not even going to bother naming them ) on Friday who had hacked Static Shock.

They'd altered it so all the files pointed to the copies on their server, and put in a bit of branding for themselves with a clickable link in the game.

We'd mildly protected it, nothing too over the top, just enough to stop the out and out ASV script kiddies, and it still got done.

Because of this I'm looking to set up a site that will be an invite only kinda thing where members can report cracked / stolen games they've found and then developers can hit these sites on mass to have them removed.

Remember Mochibot? Might help keep track of this stuff...

**Squize** · 02-18-2006, 07:10 PM

That would just be hacked out straight away.

Crazy Balls had adverts inbetween levels for sN games, gAP etc. The hacked version even removed those!

I am talking about program that removes junk code inserted by SWF Encrypt...
Just wondering if this kind of program must be something dificult to find, only a very few people find it and because of this, very few(or a lot, or none) game are stealed with it...

Isn't Actionscript 3 going to stop this by having AS stream from a server rather than actully be contained in the swf?

Still possible to hack in theory, but far more difficult...

**DayDream** · 02-20-2006, 08:57 AM

HeliAttack 3 got hacked by a few sites - I wrote a nice letter and asked them to take it done - which sadly is about all you can do...

They hacked Crazy Balls - oh man - that's a sad waste of time...

**Squize** · 02-20-2006, 09:19 AM

Yep, hacking a game that's in the public domain anyway.

l33t as you like

Just out of interest, can anyone find the .swf file in the page below, in their cache? (try any/every browser you have) If this works, i'll have made an uncacheable swf...

http://humanchimp.be/secure/stream/game.html

I haven't used any headers to tell the browser not to cache it, its just the way it is served up is different. Even if it does appear in your cache you shouldn't be able to open it ******* Decompiler - you should get a "swf is corrupted" error, but it should work fine in your browser

[edit] there seems to be a bug where the loader seems to slow right down at about 94-98%, please tell me if it happens to you [/edit]

I managed to open the php stream in the standalone flash player, then saved it as a projector. Not sure if it can be ripped from that. It was the best I could do, but then I dont have any flash hacking software.

**thehumanchimp** · 02-20-2006, 01:25 PM

oh, thats sneaky

... but fixed

**lesli_felix** · 02-20-2006, 01:31 PM

Hmmm, now it works in IE but not firefox.

**thehumanchimp** · 02-20-2006, 01:35 PM

how do you mean it doesn't work in firefox? can you get the swf from the cache?

all i did was tweaked it so that it rejected the Flash Player's user agent from accessing the swf file.

**lesli_felix** · 02-20-2006, 01:47 PM

Ok, must have been intermittent, the page wasn't working in the browser, but now it is.

Weird, I managed to get firefox to load the stream directly, then tried "save page as"

I took ages(like about 20 mins), but eventually downloaded the swf. I've tried it again, but it seems to get stuck at 423k.

**thehumanchimp** · 02-20-2006, 02:07 PM

The file you sent me comes up with "The .swf file is corrupted" when i try to decompile it, so you wouldn't be able to edit it (at least not with *******). It also does not work if you just run it, it gets stuck on about 92%. So far the protection seems to be working

**HeraldofWoe** · 02-20-2006, 03:32 PM

My philosophy, is if they crack it, do your best to ensure that they don't understand it.
I generally follow theses guidelines for protecting my games:
After it's finished, I go back, splice, chop, and mangle the code as best as possible, without messing the game up. Add unnessesary code, change simple code into the most advanced and confusing code I can make it, And use various swf protection programs as another step.
If your really violent, you can program virii into your game, with a trigger.

It works pretty well for me, at any rate.

**thehumanchimp** · 02-21-2006, 10:42 AM

all that code mangling won't stop someone from adding their image onto the first frame and putting it up on their website though.

you can?!?

**HeraldofWoe** · 02-21-2006, 12:56 PM

Well, in theory you could, but I think it's illegal. *sniffle

But it's incredibly difficult, since actionscript is OOP :/
