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

I do not understand absolutely nothing.
Only half response everywhere it has become incomprehensible.
Can somebody explain everything from A to Z (how retrieve PNG, what and how to decrypt use etc ...)
Explain everything step by step in one post, please.
Thank you in advance.

(If anyone could do it in French post also it would be nice, it's been dead for a while)

Yep new mulutibu, .bin file has been enamed 5.bin to 31.bin, it seems to have the same content, but the AES.as have changed

Hello ! I'm new here ! Someone can explain from A to Z ? How can I use THIS ?

If I have understood correctly, it's to recover the subtitles video from ADN ?

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

Hello !

How to get the *correct* constants format, please ?

In the swf file, the constants are an array of numbers, but how to convert them to the hex form ? I tried many converters, changed 0x to \x, but it doesn't work. :(

Thanks for your help !

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

I re-wrote blurg's python script and changed a few K-S-V's php script (thanks to them), to get automatically the constants and the start variable.

Code:

#!/usr/bin/env python

# -*- coding: utf-8 -*-



import os, urllib, datetime, time, re



dirName = os.path.dirname(os.path.abspath(__file__))

mulutibuFile = "mulutibu_v4_3.swf"



command = "ffdec -export script \"%s\" %s" % (dirName, mulutibuFile)

os.system(command)



time.sleep(10)



with open(dirName + "\\com\\longtailvideo\\plugins\\mulutibu6\\Mulutibu.as", "r") as startFile:

        start = re.findall("d1\([0-9]{2}\)", startFile.read())



        command = "ffdec -export binaryData \"%s\" %s" % (dirName, mulutibuFile)

        os.system(command)



        time.sleep(10)



        with open(dirName + "\\31.bin", "r") as fo:

                binary = fo.read()



                phpFile        = '''<?php

        if ( $argc < 2 )

                die( "Usage: php adn.php <encrypted_subtitles>" );



        // Read encrypted subtitles

        $file = file_get_contents( $argv[1] );

        $file = base64_decode( $file );



        // Get decryption key from aes constants

        $constants = "{CONSTANTS}";

        $start     = {START};

        $key       = substr( $constants, $start, 32 );

        $salt      = substr( $file, 8, 8 );

        $key       = $key . $salt;

        $hash1     = md5( $key, true );

        $hash2     = md5( $hash1 . $key, true );

        $iv        = md5( $hash2 . $key, true );

        $key       = $hash1 . $hash2;

        // Decrypt subtitles

        $td = mcrypt_module_open( "rijndael-128", "", "cbc", "" );

        mcrypt_generic_init( $td, $key, $iv );



        $decrypted = mdecrypt_generic( $td, $file );

        $decrypted = substr( $decrypted, 32 );

        mcrypt_generic_deinit( $td );

        mcrypt_module_close( $td );



        // Detect and remove PKCS#7 padding

        $padded = true;

        $len    = strlen( $decrypted );

        $pad    = ord( $decrypted[$len - 1] );



        for ( $i = 1; $i <= $pad; $i++ )

                $padded &= ( $pad == ord( substr( $decrypted, -$i, 1 ) ) ) ? true : false;

        if ( $padded )

                $decrypted = substr( $decrypted, 0, $len - $pad );



        // Save decrypted subtitles

        $file = pathinfo( $argv[1], PATHINFO_FILENAME ) . ".ass";

        file_put_contents( $file, $decrypted );

?>'''

                phpFile = re.sub("\{CONSTANTS\}", binary.replace("0x", "\\x").strip(), phpFile)

                phpFile = re.sub("\{START\}", re.findall(r"\d+", start[0])[1], phpFile)



                with open("adn.php", "w") as out:

                        out.write(phpFile)

Assuming you will save the script as adn.py, put :

Code:

 

adn.py

in your console and it will generate an adn.php file, then put:

Code:

 

php adn.php "picture_file"

P.S : You will need to get the picture file using fiddler.
P.S2 : When you finish, delete : 31.bin, mulutibu6.as and mulutibu_v4_3.swf files. Delete also com and mx folders.
P.S3 : Be sure to have the path of the JPEXS Free Flash Decompiler folder in your environment path variable, e.g : C:\Programe Files\FFDec

Hope it helps !

EDIT : You MUST download the mulutibu file with fiddler or from your browser to get the valid file and rename it to mulutibu_v4_3.swf, then put it in the same folder as adn.py and run the script !

Hum... Now, if the mulutibu file is downloaded with a script(python, php, whatever) we get a non-valid file. I edited my previous post.

The script has been revised BTW.

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

Hmm where is the new $start in the multibu.as ? someone can give me the sample of the line please ?

Edit: is the line is this one => var _loc2_:String = AES.dec(param1,d1(20),false);
in this case 20 ?

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

People keep PM'ing me to ask if this script currently works or not because most of them don't bother to read few pages to know what needs to be done exactly. The short answer is Yes this script still works as expected and doesn't require any other update except the two values ($constants and $start) which they keep changing on rotational basis (probably daily).

1. First you need to grab the mulutibu swf file and encrypted png file correctly. I recommend using Fiddler to save both the swf file and encrypted png file. When you try to grab the file otherwise server may send you wrong file and decryption won't work even if you follow other steps correctly.

2. Now grab a good swf decompiler (JPEXS Free Flash Decompiler) and extract new constants which are embedded as binary data in swf file. in the saved file replace all 0x with \x.

Code:

\x61\x65\x63\x64\x61\x35\x33\x30\x65\x38\x36\x65\x61\x63\x33\x65\x64\x64\x36\x63\x38\x66\x66\x65\x61\x38\x36\x31\x64\x35\x32\x64\x39\x34\x31\x30\x65\x39\x39\x34\x37\x35\x38\x37\x38\x31\x62\x61\x34\x38\x63\x32\x64\x33\x36\x65\x31\x31\x36\x34\x61\x66\x35\x36\x65\x65\x37\x65\x32\x65\x36\x39\x31\x63\x38\x64\x36\x64\x62\x30\x34\x37\x62\x64\x65\x38\x63\x64\x33\x35\x63\x31\x34\x63\x37\x30\x36\x63\x30\x61\x62\x39

3. To get the start value you need to find the call to AES function as shown in following image. it's 61 in this case.

4. after updating those two values in the script you can now use it to decrypt the png file to ass file.

Code:

php AnimeDigital.php encrypted.png

it will save the decrypted file with .ass extension.
