Hi, I wanted to experiment a little with asprotects virtualization options and tried to virtualize a simple function: int deepzero(int x){User_Polymarkerint y = 22; y = (y * x) /5; y += 100;return (y); } But it doesnt work, User_Polymarker is not defined. The polymarker stuff is defined in a file called PB.inc, but it doesnt look like c++ to me...: ' PB include fileMACRO USER_POLY_BUFFER = ! DB &HEB, &H04, &HEB, &H05, &H39, &H19MACRO CRC_BEGIN !

Hey, I am trying to inject a dll into another running process. This is my code: HANDLE Proc; char buf[111]={0}; LPVOID Remotestr, LoadLib; DWORD ProcessID = 2768; //process ID of explorer.exe char DLL_NAME[222] = "C:\\t.dll"; //here`s my dll! Proc = OpenProcess(PROCESS_CREATE_THREAD, FALSE, ProcessID); LoadLib = (LPVOID)GetProcAddress(GetModuleHandleA("kernel32.dll"), "LoadLibraryA"); Remotestr = (LPVOID)VirtualAllocEx(Proc, NULL, 1000, MEM_RESERVE|MEM_COMMIT, PAGE_READWRITE); cout << GetLastError(); //debugging ... I would now continue with WriteProcesMemory & CreateRemoteThread but VirtualAllocEx fails! The error code is "5". …

Calling a .net method in another process.
by rendari- 1 reply
- 3.3k views
Hello all Here is my problem: There is a program that starts up, and the user needs to click a "Play" button for it to start doing a certain thing. I want to make it so that the "Play" button is automatically pressed upon startup of the program, so that the user doesn't have to do it. The program is coded in .NET. Normally, I would just change the entrypoint in ILDASM to something that calls the button1_click() method, but the program is wrapped in Xenocode. For the purposes of this exercise, unwrapping Xenocode is not an option (due to political reasons and my relations with the program creator...). So, I must somehow tell the program to press button1_click() from a…

Question about Olly and interrupts

Hello everyone. Is it normal that olly can't handle interrupts like int 12h? If I try to inline-assemble interrupts i always get an "access violation when reading [FFFFFFFF]" followed by a "debugged program was unable to process exception". Could someone please explain the backgrounds of that error and whether it is possible to make Olly handle these interrupts? (sorry i'm new to asm and olly ._.) Thank you and best regards

MSVC2008 - Removing MSVC Framework code..

Hello, folks. I managed (ONCE UPON A TIME) to make it so that everytime I compile an application in MSVC2008, the output file would be free of that __security_init_cookie + __tmainCRTStartup code the compiler/linker adds in. Now I can't seem to freakin' get the results properly with project's settings. Any ideas? Here's how code looks like when compiled: And I want it only to start from this: As in, program's OEP to be this: Tried options: Code Generation -> Buffer Security Check -> No Code Generation -> Enable Function Level Linking -> No Code Generation -> Enable Floating Point Exceptions -> No Code Generation -> Enable C++ Exception…

Obfuscator

I need help. I need some obfuscator algorithm finder. I have a lot of obfuscated codes, and decoded codes. Is there any program which can lear how to do this? For example I enter him 10 obfuscated codes, and right decoded codes which he should get, and then he finds valid connection between them. For example: obfuscated: 522E 6A53 A29E 3577 3533 4A91 decoded: 50E5 562E 3870 334A 91 I also have one working converter made by some guy, but I don't know how to read the algo from it. If someone can help, please call me on private message and i will send you the exe.

x86 Code Obfuscation Techniques
by ghandi- 2 replies
- 10.8k views
Hi everybody, I was playing around with a few binary files on my computer today which employ code obfuscation at some point in their execution. The techniques used differ and yet the end result is very similar, code which causes OllyDbg or IDA to disassemble it incorrectly. The 2 ways i thought of using to see the true code is to either log the execution and then remove redundant operations from the log, leaving only the true instruction or to deobfuscate the code prior to execution. This second option is faster for sure, but it is fraught with danger also because it increases the margin for error. If the deobfuscation should incorrectly remove or change a valid opcode th…

Hi, i am trying to use bassmod.dll to play tracker music in C++. This is a start (with a little help from msdn ): typedef BOOL (WINAPI *wapi)(DWORD, DWORD, DWORD); int main() { HMODULE basshndl = LoadLibraryA("C:\\x.dll"); cout << "Handel: " << basshndl<< "\n"; bassinit = GetProcAddress(basshndl, "BASSMOD_Init"); cout << "bassmod_init: " << binit << "\n"; bassinit(-1,44100,0);} the initialization went fine -> works. However, every api has a different returnvalue/arguments, so i`d need a different typedef for every api...which is unpractical. i found this on the web: .....

NFO decryptor (possible bug correct version).
by bigboss-62- 0 replies
- 3.2k views
Hello friends, i'm proud to bring you my decryptor for NFO v1.0 from bart^CrackPl 2ooo. Why do i say "possible bug correct" ? - There is a little bug in NFO resource encryption/decryption method used by Bart. - NFO program skips encryption/decryption if first byte of resource contents is value 028h. But this is a bad method, because the first unencrypted byte of resource contents can have a value different than 028h, but once encrypted, this value may become the value 028h.- So, resource part having the first encrypted byte with value 028h will not be decrypted. - This case have been tested with original crypter and with unNFO (decrypter from Dulek). - My own unpacker che…

Module32First and Module32Next not working under Windows 7
by Guest tehgame- 5 replies
- 13k views
Hello! I tried to list modules of foreign processes with and without admin rights under Windows 7 Pro 64bit by using APIs Module32First, Module32Next and CreateToolhelp32Snapshot. It only works on my own process and like 10% of other the ones like Firefox. For the rest the Module32* APIs return FALSE. Is this associated with the Windows 7 "protected processes" security model where even administrator can't use a debugger on every process? While it makes injection to even notepad.exe impossible, is there a way around this besides not using Windows 7? I could not find a new tutorial on DLL-Injection in Windows 7.

Hi! I would like to write an application which shows all file accesses in system. With the help of madshi component I was easily able to list the file accesses, but unfortunately I can't find anything on the internet (maybe I'm using the wrong keywords :S) to prevent access from certain files. What should I look after to do that? Thanks Oh I almost forgot it I'm using delphi, but almost anything helps... except asm
