Yeah you right my friend, sorry about little and big endian misunderstanding, anyway i posted them so could be useful for other users.
About the flags it's my mystake, Because the Hex : 0100 is 256 decimal so 0000 0001 0000 0000 binary and you're right.

Ok i can suppose the files are not encrypted with ( AES/DES/3DES/RC4/RC2/RC2-64/non-OAEP key wrapping ) this because if we look closely to the version needed we found (0x14) = 2.0 and if we compare this info with PKWARE specification about the versions :

4.4.3.1 The minimum supported ZIP specification version needed
to extract the file, mapped as above. This value is based on
the specific format features a ZIP program MUST support to
be able to extract the file. If multiple features are
applied to a file, the minimum version MUST be set to the
feature having the highest value. New features or feature
changes affecting the published format specification will be
implemented using higher version numbers than the last
published value to avoid conflict.

4.4.3.2 Current minimum feature versions are as defined below:

1.0 - Default value
1.1 - File is a volume label
2.0 - File is a folder (directory)
2.0 - File is compressed using Deflate compression
2.0 - File is encrypted using traditional PKWARE encryption
2.1 - File is compressed using Deflate64(tm)
2.5 - File is compressed using PKWARE DCL Implode
2.7 - File is a patch data set
4.5 - File uses ZIP64 format extensions
4.6 - File is compressed using BZIP2 compression*
5.0 - File is encrypted using DES
5.0 - File is encrypted using 3DES
5.0 - File is encrypted using original RC2 encryption
5.0 - File is encrypted using RC4 encryption
5.1 - File is encrypted using AES encryption
5.1 - File is encrypted using corrected RC2 encryption**
5.2 - File is encrypted using corrected RC2-64 encryption**
6.1 - File is encrypted using non-OAEP key wrapping***
6.2 - Central directory encryption
6.3 - File is compressed using LZMA
6.3 - File is compressed using PPMd+
6.3 - File is encrypted using Blowfish
6.3 - File is encrypted using Twofish

So if the file are encrypted with basic PKWARE encryption it should be really easy to broken as like there are many tools to recover password from zip files, it should be not so strong....

What I'm getting at is if the byte ordering is big-endian instead of the little-endian you are assuming then the value would be 0x0001 instead of 0x0100 which would indicate that bit-0 is set rather than bit-8. If bit-0 is actually set then based on the previously posted flags it would be an bit-0 encrypted file rather than bit-8 unused which would make more sense given the apparent encrypted/obfuscated state of the file. Also since the game can be used on mobile platforms it is more likely that some parts of the program/data will use big-endian stored data. You are likely currently assuming everything is little-endian based on the platform you are working on (which is not necessarily true).

To switch the endianness of a short that has already been read into memory you can do byte swapping like this (I converted to a 4-byte int first to avoid any signed bit shifting issues, though you could also use unsigned variables without changing value size):

Code: Select all

int nLongValue = nShortValue;
short nSwappedShort = ((nLongValue & 0xFF00) >> 8) + ((nLongValue & 0xFF) << 8);

short nSwappedShort = ((nLongValue & 0xFF00) >> 8) + ((nLongValue & 0xFF) << 8);

This could be true but would be not compliant with PKzip specifications because onto documentation there is : "All values MUST be stored in little-endian byte order unless otherwise specified in this document for a specific data element" REF. 4.3 General Format of a .ZIP file
And i have checked the General Purpose Flags doesn't have any note that says : "Stored with Big-Endian" format.
Anyway i Agree with you that should have more sense considering it as 0x0001 "encrypted" the only thing i can be sure is that they haven't used any new Encryption algorythm so if it is encrypted is just basic ZIP encryption or some obfuscating operation.

Another proof of the fact that the file is not Encrypted with AES is the follow test :
I used PKzip to make 3 different zip file with the same 1 Xml file "FILE1.XML".
1. file normal zip not encryted
2. file zipped with AES 128bit encryption
3. file zipped with AES 256bit encryption

Now i copied the Hex values after the file name inside central directory :

HEX NOT ENCRYPTED ZIP

Code: Select all

0A 00 20 00 00 00 00 00 01 00 18 00 6D D0 B1 64
3C F8 CF 01 F7 B7 E4 98 5D 06 D0 01 F7 B7 E4 98
5D 06 D0 01

HEX AES 128 and 256 bit encryption

Code: Select all

0A 00 20 00 00 00 00 00 01 00 18 00 6D D0 B1 64
3C F8 CF 01 F7 B7 E4 98 5D 06 D0 01 F7 B7 E4 98
5D 06 D0 01 17 00 0C 00 02 00 0E 66 80 00 01 00
00 00 00 00


As we easy see there are Extra fields inside the encrypted file that are not present into unencrypted file.
Now i copied the values from XOR DATA.000.ZED just one random file from the data

HEX VALUES FROM XOR DATA.ZED

Code: Select all

0A 00 20 00 00 00 00 00 01 00 18 00 18 6E D4 9D
A9 A2 CF 01 18 6E D4 9D A9 A2 CF 01 18 6E D4 9D
A9 A2 CF 01


The size is exact the same of the unencrypted zip file.

It should be noted that AES would fall under strong encryption, but PKZIP also supports other encryption methods (3DES, DES, RC2, RC4, Cast5, IDEA, and Traditional ZIP Password Encryption). So it is quite possible that it is encrypted using one of the other encryption methods that you are overlooking. It is insufficient to list extra fields in only one of the possible methods as proof that the data is not encrypted (it would only show the one method is not used and even then only if they have not violated the standard, which is possible because they obfuscated the trailing central directory without apparently having the proper header and other information).

We don't have enough information to start wholesale saying "it's not using this or that".

If you read my post before i already found that (3DES, DES, RC2, RC4,...) are not used because if it was the version needed should be most recent. But as i said before if it is encrypted they just used ZIP password encryption (and can be broken) or they simply obfuscated the files with somekind of operation.

The version needed is 0x14 = 20 = 2.0
I don't think they use AES/DES/3DES... after compressing the archive, but we cannot totally exclude it. My though is if i have to use a library that already complain the strong encryption i directly use that libraries.

Just another question..i have made an XOR version of DATA_000.ZED using VBA but the results seems to be a little bit different comparing with the test file sent by Spirolone, the weird thing is that the most part of the data is the same, only some HEX values are different.
Here is the code i have used :

VBA MACRO ZED-XOR | Open

Code: Select all

Sub Macro1()

' Scelta rapida da tastiera: CTRL+s

    Dim intFileNum%, bytTemp As Byte, Prev As Byte, XorByte As Byte

    Open "C:\Users\Neo Anderson\Desktop\Zed experiment\Test_000.BIN" For Binary As #2
    Do While Not EOF(intFileNum)
        Get intFileNum, , bytTemp

To be honest I don't know... maybe a bad conversion at some point? Try to output your results at various points in the code and see if you can find where the result starts being different.

I'm starting to think that we need either a stroke of luck (one of us finds a test that gives the correct answer out of pure luck) or help from someone who's good at disassembling (looks at what the the executable does from a debugger and understands how ZED files are treated). Some time ago I tried to run the executable from OllyDbg, but I had no clue about where to look at.

No fire, the weird thing is that this happen from the beginning to the end. Obviously i cannot compare the whole file because the test file of Spirolone only contains the part with central directory, but if we compare it are different on each entry. The only reason that make sense is that we started from different DATA_000_.ZED versions.

NeoAnderson wrote:The only reason that make sense is that we started from different DATA_000_.ZED versions.

That's right, how could I not think about that? It must be the reason for sure.

Following firemind previous topic i downloaded OllyDbg 2.0 and i tried to retrieve some infos..obiously it is too complex but i want to report something...when i have analyzed the DotP_D15.exe the debugger program show me the follow message :

Now we could think that is related to the compressed data, so i decided to do the same with DotP_D14.exe and the message is not displayed.

Maybe that it is related to the Encryption???? Because the warning talk about Compressed. Encrypted or large amount of Embedded Data.
Now D14 should have the same amount of Compressed or Embedded Data maybe that the difference is the Encryption??

I post here some data retrieved from OllyDbg 2.0 i haven't the needed knowledge to use it maybe someone could find something useful.

Inside this dump i can see a calling to "cryptbase.dll" here you can see what is it :
cryptbase.dll is the Base cryptographic API DLL. Microsoft's CryptoAPI was first introduced in Windows NT 4.0 to provide services that enables developers to secure Windows-based applications using cryptography.Disassembled Instruction :

Onbiously who knows what this means....

UPDATE : "cryptbase.dll" is also used by Dotp_D14 so it should be not considered as some cryptographic encryption onto ZED...but the first msgbox is still a mystery.

UPDATE 2 : I have seen that the game cannot load during debug session, i got a steam error. So i tried to remove DATA_000.ZED from the game folder, then i started a new debug session, and i found the same registers operations and the same dll loaded, the debug session is terminated with the same steam error.
So i think that all the infos i get from the debugger are retrieved before the game load the zed files.
I used a 3dmgame version maybe someone who has an official version could check if the game can load into a debug session, so we could try to retrieve infos when the zed are loaded.

I have the same problem with 3DM, while the game debugs fine with CODEX, which has never been updated, but I think the interesting part comes before any problem that a non-updated executable may give.

I uploaded the CODEX files here, remember to make a backup of your files so that you can recover the updated version when you're done with testing.

I'm also trying to learn something new about OllyDbg from this:

EDIT: By the way, changing the last 2 bytes of DATA_010 doesn't always prevent the game from loading. Changing them to 88 8A lets the game load, while changing them to C8 CA doesn't let the game load. Making a change that doesn't let the game load can be useful for looking at where the program stops inside OllyDbg... even though I still don't know how to get the information we need from a trace run that stops at that point.

I have the same problem with 3DM, while the game debugs fine with CODEX, which has never been updated, but I think the interesting part comes before any problem that a non-updated executable may give.

I uploaded the CODEX files here, remember to make a backup of your files so that you can recover the updated version when you're done with testing.

I'm also trying to learn something new about OllyDbg from this:

I should have also Codex version, i will try to recover that version for testing. Anyway thx for the links i will take a look to that link to better understand How to use OllyDbg, hope you also find something useful.

Unfortunately i don't have found a link with the dlc.

If someone that also know something about assembler would take a look here there is a list of References assembler instruction of DOTP_D15.exe linked to ASCII description. The list is too long for direct put into the msg so you can read the TXT file attached.

OK, I found the point where the program has the plain version of Header.xml.

...now what?
