CPU "Features"
by ixiodor- 8 replies
- 11.1k views
Hi guys, I heared about DENUVO that uses a CPU bound code to make it harder to crack, some code that run only on your CPU. So i was looking for some nice trick and testings tring to emulate that. I started using CPUD changing values in EAX, my curiosity was on: MOV EAX, 0Bh CPUID This give me some values, including in EDX wich core is executing that CPUID. (core1 - core2 etc) BUT i found this "feature" , if you do: MOV ECX, 100h MOV EAX, 0Bh CPUID You reset all your registers and you get only a value in EDX, where is showed your current core... Is that normal?? I have a i7-2600, can someone with different CPU try if have same results?

So I want to write a virtualizer
by Pancake- 18 replies

Hello. Id like to create my code virtualizer, something similar to VMP, but Im havin some issues. Studying the old (1.7) vmp virtualization got the idea - you get the original bytes and encrypt/store inside VM section and place a jump to prepared piece of code which pushes onto stack EFlags, 8 registers and unique value which contains encrypted pcode pointer. Then such prepared context jumps into virtual machine. And here the vm gets byte from pcode, decrypts, finds case in switch table and executes it and so on. So after thinking for a long time i got problem emulating the stack. The original function's stack looks like that esp -> return address, esp + 4 -&…

Manual dll map - weird problem
by Pancake- 12 replies
- 11.4k views
Hello. I got my old code with this feature which i wanted to review, and something very strange happens. All the relocations/imports etc are properly resolved but the program crashes when invoking the DllMain. If i run it in olly, everything works fine (and i see MessageBox from process attach). The loader run as administrator hangs inside DllMain not displayin anything, and run without elevated privileges just crashes. When i removed plugins from olly it also hangs like in first case. What may be the cause?? Edit: After checking the dll, the function which causes freeze (when manually mapped) is "dllmain_crt_dispatch" Edit: I am doin some mistake with allo…

the namespace prefix "0" is not defined
by jay007- 3 replies
- 5.1k views
I've decompiled a .net exe using dotpeek and justdecompile and I am getting a lot of errors about the namespace prefix "0" is not defined when imported into Visual Studio. The errors are coming from XAML files Content="{Binding Path=Double, StringFormat={0:c}}"/> Binding="{Binding Path=DateTime_payment, StringFormat='{0:MMM-dd-yyyy hh:mm tt}'}"/> Binding="{Binding Path=Payment_total_amount, StringFormat='{0:$#,##0.00}'}"/> Above is an example of where i am getting the errors. This exe uses US locale and all I want to do is change it to uk. This is the only reason I decompiled it as I dont have source code.
