 Forums >>  Debuggers  >>  decompiling SWF Encryptor

Topic created on: October 19, 2005 19:45 CDT by dwarkeeper .

Hi,

I am trying to work on a flash file that has been encrypted using the tool "SWF Encrypt" 3.0. I haven't seen any documentation on decrypting the swf file. The only link somewhat related to SWF decryption was on fravia's site http://www.searchlores.org/cinix_fla.htm

Can anyone point me to any interesting articles on decompiling SWF files specially if it is in relation to SWF decryptor from amayeta.

Thanks

dk

i'm not sure if discussing about commercial protections bypass tech is allowed here in "open"rce or not , but : as far as i know SWF Encryptor is just obfuscating ActionScripts nothing more , time-line based simple flash movies are quite easy to hack and you can grab sounds and pics easily , but complex movies which using ActionScripts Heavily are not ready to decompile ( RE targets alwayes "seem" complex ) and you should make yourself ready to do some handjobs , using FLASM and FLARE you would be able to hack into any obfuscated ActionScript and see whats going on , and if you are still looking for a SWF Encrypt bypass tut have a look at this : http://www.kirupa.com/reviews/swf_encrypt_review.htm

one of my Friends is developing a very interesting swf protection using a simple flash-stub and encrypted client-server request-response mechanism , using this you wont publish your whole SWF completly , users just download a little stub and based on their requests they give needed media,ActionScript,event,etc using a signed and encrypted xml-based protocl between flash-stub and server , using this technique RE guy "should" have something like a process debugger to attach to flash movie and trace its memory and callbacks , is there anything like this avaliable ? :-)
