Re: how to decrypt and decode png files to real file (.ass)

i have take the ksv script with little adapt to decompile mulutibu swf and it work perfectly
aes.as is present inside with this fucking key XD

Re: how to decrypt and decode png files to real file (.ass)

Can someone learn to us how to find the key plz ?

On the last AnimeDigital.php script of KSV, I thank I just had to replace

Code:

$key = pack("C*", 48, 99, 101, 102, 56, 56, 56, 101, 56, 48, 99, 51, 49, 48, 57, 49, 54, 102, 55, 101, 97, 98, 100, 97, 54, 100, 51, 97, 51, 98, 57, 52);

by what I found in

Code:

http://xxxxxxxxx.fr/components/com_vodvideo/mediaplayer/plugins/mulutibu/mulutibu_v4_3.fan.swf

In which we have :

scripts/com/longtailvideo/plugins/mulutibu/AES :





private static function iv() : String

      {

         var _loc1_:Array = [99,99,57,102,99,51,50,50,54,51,57,100,54,100,50,51,57,97,54,50,97,50,99,99,48,101,102,54,100,53,55,98];

         var _loc2_:* = "";

         var _loc3_:* = 0;

         while(_loc3_ < _loc1_.length)

         {

            _loc2_ = _loc2_ + String.fromCharCode(_loc1_[_loc3_]);

            _loc3_++;

         }

         return _loc2_;

      }

After ASCII to CHAR :
Their var _loc1_ = cc9fc322639d6d239a62a2cc0ef6d57b (it's right ?)

But it's not their decrypt key, isn't it ? How to find it ?

on the adnivkey.php this topic gave to us, we have

Code:

$video = the url of the vide;

$mulutibu = "http://animedigitalnetwork.fr/components/com_vodvideo/mediaplayer/plugins/mulutibu/mulutibu_v4_3.swf?2014-12-16";

$cookie="18acd9b63ecbf50de0b8c010c2b7289f=scr7v5sbl1cigjea4r34t1o164; _gat=1; 029c45c1dfee71ebf42bcb3e469d93a8=192723e9683e7be6fe590f5e2cea5495; YWRuLWF1dGhfNTY0XzA=5416ddb290d49389328251; a2506a7b1c9f80a536e0f254bf8c954d=424441415146+A+5+B55465917+7425D595D141D1111+344444E5642+6415F404A+A5B465146+01D+D1219; _ayl_ga=GA1.2.979632947.1410784725; 4447d1d3085bd19536e003183aa51b5f=aa9fd9fdebdc9c032c71330332060f8d; _ga=GA1.2.884074519.1410784653; YWRuLWF1dGhfMTIwOV85Nzk1Mg=5416dea5ec396591227138";



...



$iv=explode("24",explode("5620",explode("d030",explode("62052404d3a215d3ffff620848",$swf)[1])[1])[0]);

I don't have this so long cookie...
And the 62052404d3a215d3ffff620848 is the key ? I don't think so...

To be clear on what i'm asking for, how to find the latest decrypt key, and with which script can we decrypt these png ?

Thx in advance for answers !

Re: how to decrypt and decode png files to real file (.ass)

the better is extract base64 key code directly in swf with ffdecode

***.fr have change the protocole cookie to take the information automatiquely

Re: how to decrypt and decode png files to real file (.ass)

New ADN protection.
AES in multibu greatly changed.

Legremlins_Keitaro

03-25-2015 01:37 PM

Re: how to decrypt and decode png files to real file (.ass)

Nothing change, AES is still the same, no difference between september 2014 multibu and march 2015 multibu in the AES function.

But yes, protection change, and now they can block IP to get subtitle => you can show the video but not the subtitle.

blurg

03-26-2015 07:00 AM

Re: how to decrypt and decode png files to real file (.ass)

they are another protection inside swf

aes.as (base script)
and aes_constantes.as (new script)

and a few ligne in aes.as script are change
(exemple ligne 147 to 171)

Yes, if you want to see the difference between the old and the new here.

AES constantes :
package com.longtailvideo.plugins.mulutibu6
{
import mx.core.ByteArrayAsset;

public class AES_Constantes extends ByteArrayAsset
{

public function AES_Constantes()
{
super();
}
}
}

and

public static function d(param1:String, param2:int, param3:int = 63) : String
{

The number after param3: int = changes every day

Re: how to decrypt and decode png files to real file (.ass)

it was just a minor change in key retrieval. rest of the algorithm is still same. i will push the update to my repository soon.

KSV	03-26-2015 01:21 PM

Re: how to decrypt and decode png files to real file (.ass)

update pushed to the repository. if they only change third parameter on rotational basis then you can update the $start variable to new one to decrypt successfully. if someone can confirm that they don't change AES constants regularly then script can be further refined to work without requiring any changes at all. i have tested this script on this file.

thx KSV you're the best

but i have just a question about the key in your update script

Code:

 $key = substr("eab023e7fdc6e8c6908e116bc550aa7099d46f866436c5a763b0fbfb73a23eceb8d313f7722af47d4530bdbd96d970d8821d0707d284b585ff5"....

how do you have this because the ligne 135 in aes.as change everyday too

03/27/2015 00H20
the new mulutibu swf

doesn't work even when i change $start variable

KSV	03-27-2015 12:53 AM

Re: how to decrypt and decode png files to real file (.ass)

aes constants are embedded as binary data in swf file. you just have to get the new constants and starting number from updated swf file. i have amended the previous commit so you can directly copy paste that data with minimal changes (replace '0x' with '\x') into script.

Re: how to decrypt and decode png files to real file (.ass)

how to get this information automatically with a script ? exemple denobis script

Code:

<?php



//get the encryption key

$swf=file_get_contents("mulutibu_v4_3.swf");

$swf        = bin2hex(gzuncompress(substr($swf,8)));

        if (!strpos($swf,"62052404d3a215d3ffff620848")) die("bad");

        

                $iv=explode("24",explode("5620",explode("d030",explode("62052404d3a215d3ffff620848",$swf)[1])[1])[0]);

                

                $key1="";

                

                foreach ($iv as $c)

                        {

                        $actual=chr(hexdec(substr($c,0,2)));

                        $key1.=$actual;

                        if (strlen($c)>2)

                                $key1.=$actual;                                                        

                        }



echo "\r\nivkey:".trim($key1);

        echo "\r\nThe key is in the file adnivkey.txt";

                file_put_contents("adnivkey.txt", trim($key1));



?>

make sure that you grabbed the mulutibu.swf file from same session as the subtitles file and their own player was able to decrypt and display those subtitles.

03-29-2015 01:17 AM

Re: how to decrypt and decode png files to real file (.ass)

???

on ADN.fr videos and subtitles play fine!

mulutibu.swf and png are from same session (28/03/2015) but can't decrypt it

I do a other session 29/03/2015 but mulu and png from this session but can't decrypt it to!

Can I post you a private message with 1 png, the mulu and your modified php from the same session?

I can play video and I have subtitle on the site, I think I do a mistake on the script but where?

I hope KSV can answer me

Re: how to decrypt and decode png files to real file (.ass)

I do some tests:
the result are the same!

I can play video subbed in chrome and ie

but I can't decrypt png (mulutibu from chrome and ie are egal...same crc32)

I dump my system memory and I can find subtitle text when play video subbed but I can do nothing with it because text is not as .ass format and text are everywhere in memory :mad:

KSV	03-29-2015 09:44 AM

Re: how to decrypt and decode png files to real file (.ass)

i have checked your provided files and you are modifying the script file in correct way. how are you saving the png file? i strongly suspect that you are probably issuing the new request to download the subtitle file. i suggest you try with fiddler to save the png file originally requested by browser. if some other user can share the png file for 28 and 29 march then it would be easy to compare if you got the correct file.

Re: how to decrypt and decode png files to real file (.ass)

the png files is compress with a http gzip :) fiddler is the solution

his png file contains properly encoded base64 data so it's not due to http compression.

Most probably they are sending either junk data or data encrypted with different key when the png request doesn't contain proper authentication data.

Re: how to decrypt and decode png files to real file (.ass)

to catch the png you would take it with fiddler

the png are gzip/deflate compress after use the ksv script to decrypt it

Put the png in atres's folder under name adn.png

Adn is again working on adownloader with de automatic decryption of the subtitles.

I've checked it with free videos. You need anyway login's parameters.

Check it.

And how to use the script ksv
I know, I'm an idiot.
