What is the purpose??
by null_endian- 1 reply

What exactly is the overall purpose of software protectors when used non-maliciously? For example, with a VM protection like Themida... What are its main goals? Is it simply trying to hide some "secret algorithm" that the developer made? Because of course it cannot hide its behavior.

Hello, i have been working on a protection for quite some time now and its finally in a stage where i need more testers to test its stability and compatibility this will encrypt the methods body and will be converted back at runtime if you are able to test this for me please give me a pm each user will be granted 48 hours access to the obfuscator and 10 files protected in this time (to prevent abuse) the protection strength right now does not reflect what it will be soon. i just need to confirm compatibility on lots of files before i can improve it further regards

What are some ways to prevent data fishing?
by Bob Dole- 0 replies
- 5.5k views
Suppose you have a data file in your protected software (assume it's protected by something like VMP or Themida) that you don't want a user to tamper with. You conclude that you will embed information into this data file which your program will use, i.e., initiate constants using this data as some kind of initial value. However, this can be bypassed relatively easily if the cracker (a) knows you're doing this to a specific data file and (b) can debug your program to fish out these constants. Then simply replaces your data file and writes a loader to overwrite these constants with the fished data. Is there anything that can be done to make this even more difficult f…

Hi, I would like to protect a small Win32 file and deciding which protection software to use. Would anyone here be able to provide insight on the difficulty of unpacking the current version of Themida (with multiple of the virtual machines) and VMProtect? In general, which of the two is more difficult to unpack? Thank you

Hi, I am looking for a packing/protector software for my MMORPG. I have tested Themida, the protection is great but performance dropped too much with the VM. I am now considering protecting my game client with ASPack, but I am concerned about it being unpacked too easily. Is there any packing/protecting software someone would recommend me over ASPack? What could one say about the difficulty of unpacking the newest version of ASPack? Any assistance would be much appreciated!

Hi, I'm new to this forum and I dont know anything about reverse engineering. I have a coder currently making me a c++ program that I want protected. I saw a previous thread which asked what is better out of themida and vmprotect. I dont know why he would limit to these 2 only as there seems to be so much out there. So much question is what software will best protect my c++ code at the moment from reverse engineering. Note i understand from what i have read nothing is 100% protected but what will slow someone down the most? So far i have looked into Themida/ Code Virtualizer ,VM Protect , Obsidium but I'm not qualified to make a call on any of them or something…

Research in (Virtualization-) Code Obfuscators?
by miraculix- 5 replies
- 11.9k views
Hi, I want to write my Bachelor's thesis on Code obfuscators in DRM. The plan was for me to describe different protection features and then implement some of them by writing my own little code obfuscator. However, now the uber-boss of the department intervened because he thinks the topic lacks an adequate "research question". That is, the thesis has to answer/solve a concrete problem or question, not just reimplement existing techniques. He might be right, I guess. But I cant think of a good and appropriate "research question" in this way. Can anyone imagine a good research question in that regard I might cover? [If this post is in the wron…

Hello, I'm trying to change the protection flag of an address in memory, it is set to EXECUTE_READ (probably) and I'm trying to change it to EXECUTE_READWRITE to run my hooked function , I've injected a dll inside the process and created a new thread then I'm trying to use VirtualProtect to change it, but VirtualProtect keeps failing and the protection doesn't change .... it's like it has been disabled (but only on certaing pages, since If I try to VirtualAlloc a new page, I'm able to change to modify the protections of it) :/, I've tried to check if the VirtualProtect has been hooked but it's not, how is it possible that they made the VirtualProtect to not work wit…

I'm trying to implement a Native Runtime protection scheme just like how some protectors does, (keep in mind [Native Runtime != Native Wrapper]) I found it interesting so I wanted to do something similar to that just because, and because of learning purposes, I think this little project can open me doors for learning what I want to learn which is be more fluent in C# or at least I hope so. Basically what I would like to apply is the same principles, I know they take some measures that are kinda obvious and prone to reverse for example Jitted methods, MITM Jit Attacks, etc, etc. However, like I said, I just want to do it. I was looking i…

Create a simple packer
by 0ne- 5 replies
- 9.5k views
I want to write a simple Packer, but before I start writing, I was planning the design of the Packer. The design is as following picture: http://imgur.com/qsKI7ty Step one, encrypt the code segment and data segment. Step two, add a new segment, which will be the Stub. Step Three, Change the OEP.to stub EP. The first step and third step are easy, but the second step is not simple. The Stub contains function calls (eg VirtualProtect). 1)From what I realized every external function should be in IAT, I have to add the function to the IAT? Is there any other method to call external function, without get in trouble? I saw several articles on this subject,…
