[cezarica 2]

Hi,

 

could someone tell me how to decompile attached file for the sake of learning Python?

Attached is the entire inspect with no error, but I want it back to normal py code. How is this encoded?

How did you decode the file?

 

Как вы расшифровать файл?

Как вы расшифровать файл?

It's a custom opcode. Just skip the custom code.

# File: movingforecaster.pyc (Python 2.7)

 

I don't think to decompile the obfuscated code is a good idea. Even though the obfuscate skill is poor.

 

It's show the attitude that I don't what anybody modify it.

 

The cheat mods were used to sell in China. I don't want it become a part  of money tools. So I disabled the mod in China.

 

I sincerely hope that you delete the reply.  

 

PS:  I tried to decompile the obfuscated code by Pjorion or mercger. But I failed. 

[cezarica 2]

And how to skip that? Could you elaborate?

 

Oh sorry. StranikS_Scan please edit and hide the decoded code.

 

А как, чтобы пропустить? Не могли бы вы пояснить?

Ой извините. StranikS_Scan пожалуйста редактировать и скрыть декодированного кода.

adri1对不起 我说出你的秘密了

Some things can not really say it
You always want to study it
I am also here to learn decompile
People here will not tell you

Send me a PM then. :)

 

Отправить мне в ПМ то. :)

This mod is not protected. Changing one or two bytecode on the fake code - it is not a defense.

 

To real obfuscating and protecting mods use functions in PjOrion.

Yes, it's not in a good protected. Until the day before yesterday, I just found PjOrion and your post about python code obfuscation.

I make the mod at the version 0.9.4. Before I put it on 4cheat, I was looking for how to obfuscate it. At last, I make a new opcode to disable the simple decompile program.

 

May I ask three question?

1. How you obfuscate the pyc.  

I fount it combine a lot of jump and except jump. Do you add new code to the original code and modify the untouched byte. Or you just modify byte to implement obfuscate.

 

2. Can you decompile the pyc under PjOrion's obfuscation.

 

3. Do you have any idea about WOWS's pyc.

How does they compile the python? Do they use a special version python.

我没什么秘密，如果是本着研究和学习的态度，我愿意公开我的源码，实际上也没什么高难度的内容，我只是不想看到我的插件跑到国内的作弊插件软件上。

我也知道这些作弊插件软件的作者有一定的技术实力。比如用了base64和marshal加密代码然后从服务器端动态获取代码。所以不加密或者简单的加密没什么用，像修改opcode这种已经是有一些资料而且涉及一些比较难的内容的办法了，当然这种办法肯定是无法阻挡StranikS这种牛人的。但是我本来也并不是想把代码藏的多深。

其实我挺害怕在外服论坛看到国人，因为国人有一些技术实力的大都认识。不认识的人，我不确定他们是否是外挂插件的传播者。

1. How you obfuscate the pyc.

 

 

 

Use obfuscated+protected in PjOrion. It's all that I can write to you.

 

2. Can you decompile the pyc under PjOrion's obfuscation.

 

I can not

 

 

3. Do you have any idea about WOWS's pyc.

 

This is a game for the closed test, so the game files are encrypted of the game engine. When the test is finished the files will be decrypted.

StranikS_Scan could you elaborate on how you decompiled the above code?

No

[cezarica 2]

I honestly want to learn new stuff, see how someone implemented various features and not to decode other people hard work, take credit for it and sell that on whatever site to whomever offers the most. There are a lot of assholes doing that already..

 

Wanted to see how (the method) one would decode that pyc file, the process of getting the code, not necesarly adri1's code. I managed to decode some of the scrips I found around, and based on a few examples managed to make my own things that kept for myself.

 

Thank you anyway.
