Security Flash Game Hacking
Oct 6, 2010
I usually organise tournaments on my site (flash based) and this time I have added a tournament in which users have to complete a jigsaw puzzle and the one who completes it in the least time wins some prize. As the jigsaw puzzle always produces random location, it is difficult for them to hack. They can't even directly download the game as it can't be downloaded using flash saver etc. But I want to know if they can make a program which completes the jigsaw puzzle automatically.Even time can't be hacked as I use time also tick on my server side so I match the time submitted by the game and the time stored in my server.

I haven't fully grasped how the flash security model works, and now I've ran into a problem. I have a base SWF that loads a game loader swf, which in turn loads the actual game.What I'm trying to do is taking a current bitmap snapshot of the running game. This works fine before the loader swf has loaded the game. When the game is loaded, I get a security violation because the game has images pulled from facebook. Is this something that can be solved on my end, or restricted by security in the game swf?

I am planning on making a game with actionscript 3.0 (flash). However, I am having some security issues on saving user points. To be more specific, read below and you'll understand what's the exact problem. You are starting my flash application. PHP creates a session for your username. Playing for few minutes and reaching 750 points. You click on "Save my points" button. It connects "game.php?points=[]" with your point amount, hence, game.php?points=750. PHP connects to MySQL and does an update/insert query with the username you entered when opening application, and gets the points with $_GET['points'] as you can see on 3.
The issue is, Anyone who could directly browse "game.php?points=999999999999" would have his points saved in the database. I thought about encrypting the points, however, Flash is a client-side application and anyone could change the "points" value with an application like "Cheat Engine". Once they change the points, encrypted points will automatically be generated by Flash.
I also thought about creating a private key for each player on their signup and encrypt accordingly, but it also won't work because once an user change his points with Cheat Engine, flash will automatically encrypt the points with given private key, hence, another useless theory...

My SWF resides on domain A, is loaded by a web site on domain B and is trying to ping URL (URLLoader.load) on domain C. But I am getting "#2048: Security sandbox violation" .. why? Of course I have read the manual, I saw the security white paper but I do not understand it. Don't you know any blog or such where it is explained for dummies? With lots of examples and maybe a table showing what is allowed and what is not?

I am getting a strange problem while I am making my release build swf.The swf is supposed to make some internal server calls and then display the data and also play it.When I make a release build swf and excute it, while making server calls it throws exceptions likeSecurityErrorHandler: [SecurityErrorEvent type="securityError" bubbles=falsecancelable=false eventPhase=2 text="Error #2170: Security sandbox violation:file:///Path to the swf/WebPlayer.swf cannot send HTTP headers to **Method Name to bring data from the server***]And after this nothing can be done as everything depends on the data from the server..I have updated my cross-domain.xml on the server to support the master-only policy file but that also didnt ..My cross-domain.xml is
<cross-domain-policy>
<site-control permitted-cross-domain-policies="master-only"/>
<allow-access-from domain="*"/>

I'm having trouble with an AS3 AMF RemoteObject request that is hosted on App Engine. I have a crossdomain.xml file in the root of the domain, and also one at the remoting endpoint.Here are the contents of the root crossdomain.xml:
<?xml version="1.0"?>
<cross-domain-policy>
<site-control permitted-cross-domain-policies ="all"/>[code].....
Loading the swf file and testing it on my machine works just fine... I think that may have something to do with me having the debugger version of Flash Player. When I push it up to App Engine to make it public, other clients access it and get a Client.Error.MessageSend Channel.Security.Error error Error #2048 url: http:[url].......I am using Flex 4 beta, and the App Engine Python runtime. I have tried full wildcard in the crossdomain, and even accessing the data endpoint at a relative URL so as to avoid this error.

i wrote a flash script that is embedded into an html page. The flash script (AS3), needs access to the users microphone and camera. I've seen on other websites when they want to use my camera/ microphone flash automatically pops up a box asking the user to permit.
In my case, even though in my global settings for my webpage it says "always ask" under permissions, flash doesnt ask me anything and just blocks the script from accessing the microphone. The script loads fine, just doesnt prompt for access and the user has to manually right click, and go to settings and put setting to "allow".
Searching for this topic on google is rather difficult as there is too much irrelevant stuff with the same keywords.
Edit: This is how i embed just in case im not doing it right.

I've got a Flash movie, loading data from an external URL. In fact, it's a RSS reader inside a banner.Everything works perfectly when the Flash movie and data URL are on the same domain. However, if the Flash movie is on another domain, Flash security kicks in.The manual says that I can allow a domain trough Security.AllowDomain()
system.Security.allowDomain("http://www.mydomain.abc/")
xmlData = new XML();
xmlData.ignoreWhite = true;

I am building a photography web site with flash and I found a really cool slide show extension plug in (www.slideshowpro.com) were can easily upload and update my portfolio slide shows.when I publish out to HTML, I test it in a browser and I get this warning when I click on the photography page.I read in adoby help and it said flash developers can allow communication between sites with this AS code Security. allowInsecure Domain ("nathan44. slideshowpro.com");so I added this code to my actions layer on the firs frame in "scene 1" and to the actions layer in the photography section. But nothing changed i still get this warning when ever I publish out to an HTML, when I just preview with control + enter i can view the sideshows fine.

I have build my entire website with flash and embedded several swf objects (slideshows) into it. everything always worked fine when I published it as swf movie.but now that I want to upload my website an error message occurs saying:Error #2044: Unhandled SecurityErrorEvent:. text=Error #2140: Security sandbox violation: file:///mylayout.swf cannot load file:///slideshow_1.swf. Local-with-filesystem and local-with-networking SWF files cannot load each other.I know that it has something to do with the fact that one of the swf is local with filesystem and the other local with networking. but in my publish settings i told it to access local files only.but i dont really know what your are talking about. i am hosting my website at besides that i have not uploaded it yet. i am just testing it offline.

How to I get my security policy working? My parent swf parses an XML doc and loads 2 children. It throws a 2148 security error, and only works in the Flash IDE. PARENT SWF 'I put it at the top of my code. That seemed like the proper event flow' flash.system.Security.loadPolicyFile("crossdomain.xml"); I've referenced my security file from my swf. I Also published my parent swf as 'network only' and put all the crossdomain.xml and everything else in the same folder. I need to click on the animations and have them place from a local computer at a kiosk. POLICY FILE 'Used"*" since there's not URL, it's all local'

How can I disable crossdomain.xml check when the executing swf has been loaded on localhost?
Error #2044: Unhandled SecurityErrorEvent:. text=Error #2048: Security sandbox violation: http://localhost:2541/xxx.swf cannot load data from http://www.com/xxx.swf.
I want to assign full trust to the HTML5 web application running locally. I want to disable any crossdomain checks.
Some external servers do not provide crossdomain.xml for their hosted SWF files.
I am running locally. I want to have full trust for debugging purposes.
How do I do that?
I will not consider AIR as it cannot be used from HTML5 application.
Adding the url "http://localhost:2541/xxx.swf" to "C:UsersArvoAppDataRoamingMacromediaFlash Player#SecurityFlashPlayerTrustu.cfg" did not help.

Over the years I've become an uber-nerd when it comes to flash game development. Now I'm thinking about looking into using my skills for helping other game-developers out there.I want to develop an API in AS3 which will allow the developer to do (as a start) the following:Display a dialogue which lets the user log into their "account" (hosted on my site).Send a score/value to the website and attribute it to the logged in user.Unlock an achievement (achievements will be set up by the developer in the web interface - which is where they will also get a key of some type to use with their API.Display highscores, other players profiles in-game, etc (show basically any stats in-game).All easy enough to develop straight off the bat. However; where it becomes frustrating is security. I'm not expecting an indestructible solution that I'm fully aware isn't possible, but what would be the most defensive way to approach this? One thought I've had was converting my API to a component so there's no access to the code (unless you decompile). The problem here is it's just not friendly to the developers, though it would allow me to create my own graphics for the UI (rather than coding many, many sprites).Private/public keys wont work unless there is very good protection against decompiling.

I'm building a flash project that will be ran with a wrapper of some sort to give flash extra controls. The issue I'm running into is streaming video from a web domain while the .swf is located locally on the users computer. I'd rather not ask my clients to go into adobe's security sandbox and allow it them selves. Is there a way to auto allow a file to communication externally for streaming? I know an Adobe Air app named Ambience that streams mp3s. Anyone know how this can be accomplished?

So, I'm pretty sure this is impossible, but is there any way to "re-skin" the box that pops up asking you if flash should be allowed access to your mic and webcam? I'd really love to make that box fit with the rest of the design of whatever I'm building.
Also, if I have several swfs that use the mic/webcam inside one larger shell swf, will the dialog box appear once for each of the sub-swfs, or just once for the large one, and those settings will be applied to all the sub-swfs?

mp3 playback security with Flash player. I am making a mp3 player and don't want to give user access to download the mp3 files from server. But according to Flash player functionality, it's getting downloaded in cache. Also with Firbug user can see the mp3 file path.I would like to have any good suggestion for this development, without streaming server. Is it really possible to secure mp3 files with Flash player? If yes then please let me know your feedback for the same.

We're trying to create an app for OpenPeak. The Flash app will act as a client to a Java server on another computer on another domain.The Flash app client connects via XMLSocket. The Java Server uses ServerSocket to receive a request and send back a message.In order to trust the server, the Flash client needs a socket master policy file to tell it that the server comes from a trustworthy domain. According to an article on Adobe, when a connection has succeeded, the Flash client automatically requests the cross-domain policy or socket master policy file on port 843.Still, even when we implement it according to the tutorials and recommendations we have read, the Flash client continues to throw the following security error:[code]We've tried logging the policy file request during testing to see if there was any call made to port 843. There was not.Interestingly, even without a policy file, the Flash client still manages to send the first data message to the server successfully. It's just when the server tries to send back a reply that the entire thing hangs for about 10 seconds before the security error above is displayed.
