Meet Anti-Cheat Toolkit: prevent cheating easily in your Unity3D game!

Hey, dear fellows!
Today I’m glad to present you my first contribution to the Unity3D Asset Store:

Anti-Cheat Toolkit (ACT)!

This is a tiny toolkit, created to help you protect your Unity3D project from many cheaters / hackers (not from all – skilled and well-motivated person can hack anything). Current ACT version allows you to protect sensitive variables and PlayerPrefs from cheating.

Feel free to watch a small video I made to show how to cheat your game (or whatever) and how ACT allows you to prevent such cheating: http://www.youtube.com/watch?v=6–2JECbpSE

So, currently ACT allows you to keep variables safe from all kind of memory searchers (Cheat Engine, ArtMoney, etc.) and prevent your saved PlayerPrefs data from altering by any person on any platform.

Just add ACT DLL into your project and replace PlayerPrefs to PlayerPrefsObscured, sensitive int to ObscuredInt, float to ObscuredFloat, etc. and you’re done! Really :)
This is all you need to do to add some protection from cheaters to your project in no time, no any additional steps required!
For more flexibility I added custom crypto keys usage (not necessary, but feel free to use it), if you’re nerdy enough :)
ACT is very simple and intuitive to use as you can see – you shouldn’t have to know something special at all. Hope you’ll like it!

Introducing SWF iD: Flash reverser companion

Hey, dear friends!
I’m very glad to share with you one nice freeware tool every flash reverser (especially beginner one) should have in his toolbox: SWF iD!
It was recently released to the public by Lizard. The purpose of this tool – to allow reverser make fast first glimpse at the target swf file, study its protection (if present), compression, AS version, tags, etc.
Here is how it looks like:
SWF iD

You could find it very similar to the famous PE files analyzer PEiD

More screenshots: http://swfid.je1.ru/screenshots.php

Please, note the Process Scan button – it allows you to search for SWF files right in the processes memory and dump them to disk, very handy addition. This is a search example in Flash Player process, running SWF packed with SecureSWF:
SWF iD process scan

Processes IDs will be added to the processes names in the future versions

You can see here unpacked swf found and detected as Secure SWF 4.0 protected. Process Scan can ignore standard built-in Flash Player SWF files (Filtration FP Noise checkbox) and can skip fake SWF signatures as well (fakes detection sensitivity will be configurable in future versions).

SWF iD supports plug-ins and ships with few default: http://swfid.je1.ru/plugins.php
Keep in mind tool is still in early development stage so you’ll meet some bugs for sure, feel free to report them here: swf-id{at}ya.ru.
If you have any suggestions, ideas or anything else to say, just post all this here in comments, or send directly to author using email I mentioned before!

Advanced DoSWF encryption? Challenge accepted!

Greetings!
As I previously wrote about flash files unpacking, you can achieve that using static unpacking or dumping swf file from memory usually. There are some exceptions however, and I’ll tell you about one such exception in this article.

Developer of the DoSWF protector (made in China) used few simple yet interesting tricks to prevent revealing of the original SWF, I like something harder than clicking one button)
I guess many poor “hackers” (as they like to name themselves) have no idea why dumped files are not working, and can’t do anything about it.

Let me show you an example how to unpack SWF encrypted with DoSWF (many pictures ahead!)… Continue reading
