ActionScript 3.0 :: Protecting SWF Files From Malicious Intentions
Jul 13, 2009
I am about to upload a flash application to the web and I was wondering what things i should consider (security wise). What are things I should do (and know) to "protect" my swf files from malicious intentions (whatever they may be)...
Somethings I am concerned about are:
*my swf file being stolen / someone else will claim its their own
*swf file being decompiled and things that can be done once decompiled
*...and a host of other security issues that i might not be aware of..
I am basically creating an online portfolio in case yall are wondering either post the information here, give me links to articles, videos, or whatever...

Right now, if someone types in a popup window comes up asking if they want to download the file.I want my swf files (I'm building a site on the Gaia flash framework) to have access to all of my flv's/videos, but I don't want people to be able to download them.e Flash IDE to 'protect' your swfs (though I know there are ways around that) - but for flv's do those have to go in some type of special folder with a .htaccess file to protect them - and if so, how do I let my swf's communicate with the flv's and load them when necessary.

protecting SWF files written in AS3? I've tried some trial software but they didn't seem to do very much.
Its sad when a developer spends months developing an app/game only to have it stolen, edited, recompiled and sold by some moron without principles or ethics.

i would like to know if there is any solution to remove the warning that shows up in the file browser which comes up while using filereference.download to download files. I can see that this warning comes only on Flash Player 10 but not with earlier versions. If you're wondering what exactly am I talking about, check the image below:

I know there are softwares which can protect the swf files from decompilers; where the actionscript appears to be gibberish once decompiled. My question is is there any way i can make sure the swf catcher cant find the swf file to download?

I'm experimenting with loading an array of elements into my Flash project using the LoadVars property (I'm using Flash 8 - AS 2) The elements are queried from MySQL using PHP to a page named "elements.php" and loaded into the Flash file. It works fine, but I'd like to be able to protect the "elements.php" page so that the variables queried from this page cannot be viewed by someone who types the absolute path to the elements.php file in the browser address bar [[URL]. Using includes, I'm able to protect other pages in my site from direct assess but these methods don't seem to work when the URL is called from within my SWF file.
My fear is that someone might decompile the swf to reveal the LoadVars URL present in the actionscript. I know there are ways to obfuscate the code, but I'm not sure how well these methods really work. I also understand it is practically impossible to completely hide the code from someone who is REALLY intent on getting it, but I'd like to make it as difficult as possible.

So the first frame will be password protected if someone know the password he can go to next frame. I want that passwords was in .txt file (so every password have his own .txt file). And if someone type correct password and go to next frame the .txt file of this password will be deleted (so you can use password only once). I want to put this game to my website so the txt files will be in online folder.

I've made a game in flash that I want to upload onto my site but I don't want it to be able to get hotlinked to or hosted from/on another site.
What would be a good way to prevent this?
I first thought of getting a varible from a text file and using an IF function on load to check if that var was loaded but that would only prevent Hosting.
I then tried putting the var in the html code for the swf but that don't seem to work so well, when I refresh the page the movie randomly seems to play normally or goto my "this is stolen" screen.

I have an application developed in Falsh (EXE) that is to be distributed on CD-Rom and was wondering if anyone had any suggestions on protecting the application from copying.Is there a way within the dev environment I can "stamp" it to prevent copying, or another technique?I don't mean using getDate(), getMonth(), getFullYear(), etc.I have used this to create an expiry date on versions that are being distributed, which then shows an out of date message (which can be easily worked around with the system clock unfortunately).But I wish to protect the disk from being copied, and wondered if there was any techniques from within Flash to do so.Glass mastering and watermarking is not viable as it'll only be a very small duplication run (10, maybe 20 disks).Alternatively, are there any stable utilities that anyone has used (and recommends), prior to me investigating available commercial copy protection software?

how to password protect a swf uploaded to my website.
I have a swf that is a work in progress, is NOT ready for public viewing, and i need some critique from a friend in the USA, and if i could upload it and give her the password, it would be viewable only for her, or for whoever else i'd give the password.
So, i've looked at a thread from a while back,[URL], which explains stuff that is beyond me, on xml programming.
And, i am aware that the Publish settings has an option to add a password, I tried it but am unsure what that does if anything.

We have RTMP and HLS live and vod streams running on FMS interactive 4.5. Given that FMS documentation on security and content protection is very scarce I have the following questions:
1. How do I protect my live and vod RTMP streams from embedding in other webpages?
2. How do I protect my live and vod RTMP streams from capturing with special tools like rtmpdump?
3. How do I protect my live and vod HLS streams from embedding in other webpages?
4. How do I protect my live and vod HLS streams from capturing with special tools?
As far as I understood RTMPE is flawed by design because it can be captured with rtmpdump. SWFVerification also fails, because one can use exactly the same SWF player on their site. Can I somehow tell to my FMS server that it would allow only SWF player from my domain?

I usually, use SWF Protection, to protect my swf's from decompiling. It also adds a load bar to the swf.
The problem is that I have codes like this:
logo= new marca();
parent.addChild(logo);
logo.mouseEnabled=false;
I use parent, because I need to put the movie clip above everything, because my application allows the user to add a lot of things to the stage, so a don't want anything covering the logo.
The application works well while unprotected, but If I protect it using SWF Protection, then, I get just white screen. Nothing appears after loading.
Is there another way, to put a movieclip above everything, without being necessery to add a ON ENTER FRAME LISTENER, to update the movieclip deph, to keep it above everything?

Aside from using browser headers, I want to blacklist/whitelist browser and plugins from my site so that I can prevent these older unpatched systems from (1) being a general user of my site (2) removing those 'targets' from would-be-attackers reach.Is there a standard way to use Whitelisting or Blacklisting to control browser access to my site? For example, I want to prevent any browser that has outdated Flash, but I want to permit them if they have no Flash at all.

With all the recent hype about JavaScript and HTML5 replacing Flash, I wanted to know - How would it be possible to protect client-side js code? Of course, it is possible to obfuscate it, but that would only make it a little harder. Also, for games which submit high scores to the server, wouldn't it be incredibly easy to modify those scores before they are sent to the server? I know even Flash files can be decompiled, but they can be obfuscated and flash decompilation is not as easy as modifying data in JS - could be done easily using a plugin such as Firebug. I'd like to know everyone's views on this.

I have some files in my src directory, some are .class files (Java class files) and some are .properties files, when I create the Adobe air native installer these files are not included. Why is that? How can I work around that?
Also it excludes .mxml files, but that's good. I'm sure that's related, how to change what it includes or excludes?

I have created a flash file that allows you to click on a thumbnail image and larger image appears ontop of a tshirt. The same way as a gallery would work. The images and thumbnails are pulled in through xml. However I have a problem, I need the images that appear on the tshirts to be .png files or gif files as the tshirt colour can be changed. At the moment my flash file will only display jpegs! I dont knwo why. The jpegs leave me with a white background, so I need the transparency of a png/gif. My actionscript is:

My users upload a certain kind of text file that sometimeshas references to images stored locally on their hard drive. I needto check this file either on the server or within a flash app tosee if it has these references and then grab those images in aflash app to upload to my server.So I can use FileReference easily enough to have users uploadlocal images. But FileReference requires users to select their files with a dialog box. I can't have that. Myusers wouldn't know where to look and there are typically way toomany files, sometimes with the same name but in differentdirectories.
I can also just use URLLoader with a local URL, I guess I canprobably just use Loader too? That works great. The problem here isI can't communicate with both the server and the local filesystemin the same flash application due to Flash's security sandboxrestrictions. So I can get out of those security restrictions byplacing or editing a trust file in designated locations on variousOSes. I then need to install this trust file which is more invasiveand confusing to users then I want to be...Java's method of accessing local files from a web applet bysimply signing the applet with a certificate and having a dialogbox popup where the users grants access is ideal. Is there anything

I was messing around with some old examples, and I ran into an unfinished example where several 30k-100k XML files are loaded and stored as a string into an Array. The code looks basically like:[code]Basically, when I trace the 'this', the order of the files that are loaded is off. Out of about 10 tries, about 3 times the order is perfect. The remaining 7 times, the order is a bit off. Does anybody have a suggestion on how to ensure the files are loaded prior to the next file being loaded? I tried placing a while loop that basically delays the clock for a few milliseconds, and that didn't work either. Besides, that is not really a good solution to arbitrarily waste clock cycles.

I installed Flash CS4 Professional trial version for school use. It wouldn't install successfully. I deleted the font files the troubleshooting guide said to, tried again, but gave up. (I'm afraid to run regedit and mess up everything else I have loaded.) (I previously had the Fireworks CS4 trial version loaded, then uninstalled it.) My problem is this- I have it running, but it saves files and then they can't be opened, even if I use the save function often- it's worse when I create the file, test the movie and then save.If I try to open it again, it says "cannot open file." Once it opened a copy I had saved, and it appeared blank, even though it was 544 kb file size. I only need it for a few more days, one more assignment and I'm afraid my previous files are corrupt. I have Windows Vista Home Edition.

I'm working on making a pretty chunky game engine for games I plan on making, but I was wondering if you make external AS files unopenable such as .lib files, so that if I give it to a friend that wants to use it, he/she cannot change my code. Is there anyway to make external AS files unopenable? Also, obfuscation isn't an option for this problem as it only stops the people who hack the finished product, not stopping people who have access to the actual files.

I am constructing a Flash animation and I was hoping to build it by scenes. These scenes would be individual SWF movies that I could import into my final Flash file in consequential order and when finished I would have a completed Flash Movie. There would be no interaction beyond Play/and replay. Where can I get information on how to construct this and is this a recomended way to do it?

I have no experience with Adobe Flash because others have done this out of house in the past. (time has come for me to learn - quickly)
I need to simply create "swf" files from a number of videos I have finished in Premiere Pro 5.5.
These videos are 800 x 600 videos that display at "point-of-sale". The spec is swf and not flv.
(I do not need to do anything else in Flash apart from create the video file with the swf extension.)
