Programming and Coding

Hey guys, I am looking for a KG template (MASM) that would bruteforce a serial that is 15 characters long (0-9 chars only). The ripped code is 2.5megs as a text file and consists mostly of IMULs & IDIVs, etc. There is a total of 17 math checks done. During each check, the char manipulation is done on 13-15 characters from the serial as well as on chars from the username; these are done independantly and the if the results match then variable "Valid" is set. Subsequent checks also set/reset "Valid" accordingly... I realize I have to loop through the whole thing until all criteria are met so I am looking for the SPEEDIEST and MOST EFFICIENT way to do it. I intended…

I'm leaning BHO programming with this tutorial. />http://www.codeproject.com/KB/shell/BHOinCPP.aspx I used VC6 to compile the project, and got the error: cannot convert from 'const struct _GUID' to 'unsigned long' from the line: const IID CClassFactory::SupportedIIDs[]={IID_IUnknown,IID_IClassFactory}; SupportedIIDs is an array (class member of CClassFactory) which is declared as: private: static const IID SupportedIIDs[2]; in SDK (Guiddef.h), IID is declared as: typedef GUID IID typedef struct _GUID { unsigned long Data1; unsigned short Data2; unsigned short Data3; unsigned char Data4[ 8 ]; } GUID; the attachment is the VC6 project. Thank you for hel…

Hello masters I have a problem with using drivers in delphi , how i can use a driver file with sys extension , is there any chance ? Thanks.

Ok so I'm messing around with injecting dll's into other processes. The code I have works perfectly fine on any 32 bit machine but completely blows up on W7 64 bit. If it's compiled for pure 32 bit it works ok but only with 32 bit programs. I'm getting "CreateRemoteThread exited with error 8" Any ideas? public unsafe static bool LoadRemoteLibrary(Process process, string Dll2Inject, out IntPtr lpModule) { lpModule = IntPtr.Zero; if (!File.Exists(Dll2Inject)) { throw new FileNotFoundException(String.Format("PE File '{0}' not found.", Dll2Inject)); } UnicodeEncoding enc = new UnicodeEncoding()…

can someone help me with this algorithm? thanks in advance .. algoritmo.rar

How can I send packages to Delphi? I want to hook certain API's for a game and then send the package for Delphi ... Help me;) thx a lot

Yohoo hord of fans, Here is my VGCrypt v0.75 decryptor. You can say that Lutin Noir has already released a decrypter for it, but his decrypter doesn't remove decryptor section or code. It just decrypt it and restore original EP. My decryptor removes unwanted sections and code, so the file get smaller... Tested with VGCrypt v0.75... As usual, source code in masm and cryptor are also included for interested ones... See you soon ...

Hi Friends How To Use Register Of Dr0,..,Dr7 In Visual Basic And Set Hardware BreakPoint ? Thanks

Hi, I have the name, base address and size of a section which i have to save to disk. I have to do this with C/C++ and not PE tools or something like that. Well I guess that's not a big problem, just save each byte from base address to (base address + size) to a file right? Then I have to attach this section to a binary with c++, but i am not sure how to do this. First I have to write the section at some address in the binary, but what do i have to edit in the PE header? Is there a way to add a section and use it directly, while the program is in memory? Primarily I'm talking about code sections here.

I want to make dll with Decorated Names by using masm32 the export name is like ?MoleBox_GetUserMail@@YA?AVMoleString@@XZ when i wrote in .def file like this LIBRARY MYCLASS EXPORTS ?MoleBox_GetUserMail@@YA?AVMoleString@@XZ=MoleBox_GetUserMail @1 ?MoleBox_GetUserName@@YA?AVMoleString@@XZ=MoleBox_GetUserName @2 when i make the dll,i find it is ?MoleBox_GetUserMail rva: 00001006 ord: 1 ?MoleBox_GetUserName rva: 00001014 ord: 2

Hey guys! Well I'm currently doing some experimenting with coding an exe packer/protector. I've got it working up to the point of loading and packing an executable written in C++ compiled with Dev-c++ and it works fine. Whenever I compile the same source code in Visual Studio 2008 pack it and run it I get "Not a valid executable file!" Anyone have an ideas? I can post the code if need be. Thanks in advance

Hi, I am stuck at converting a negative signed value to an unsigned value in vb.net 2008: e.g. signed: -1111111 unsigned: 4293856185 I am trying to do a "NEG" operation... any ideas? deep0

hello there im trying to make some usermode hooks to explorer.exe process my first goal is to hook findnextfileW api but when im going to open a directory explorer crashes.I have spot an access violation but i cant spot why that happened here is my source code diafora.h typedef struct AdressEs{ //....target DWORD FindNextFileW_; //....redirect DWORD FindNextFile_; //...data BYTE FindNextFileData[6]; }AdressEs;void HoonOnAddress(DWORD addr,DWORD dst); void UnHoonOnAddress(DWORD addr,BYTE *patch); int JMP(DWORD func,DWORD tramboline); bool FindNextFile_(HANDLE hAndle,WIN32_FIND_DATAW *FileData); void DumpFirstBytesBeforePatch(DWORD addr); void InitializeHook();DWORD p…

The key isn't generated from a username. I managed to get the key validation routine, and it is rather complex. I was able to translate it to Python code, and I tried generating random numbers and trying each generated number with the validating routine, but I was not able to get a valid key, since the chance of each randomly generated number being valid is near 0. What is the best way to generate a valid key?

I have a binary with 3 radio buttons, I want to change the default startup selection and resource hacker does not allow me to change the default value. So I must assume the GetDlgItem is where and how the control is initialized. When I break on GetDlgItem, the stack never shows the known control ID for the three buttons I want to switch in code. Since I don't have the source code, I have to do it in asm, but I can't really find any methods that deal with this. Any thoughts? Thanks

I am designing a delete function for a file manager i am coding however, i want to be able to delete a file even if you get that stupid windows "cant not delete due to blah" message. programs like unlocker. http://ccollomb.free.fr/unlocker/ search for all open handles for a given file and close them how is this acheived? i know after all handles are closed the obvious DeleteFileA is callled to delete the file. example, file1.txt has handle 1 and handle 2 open. search and find the handes CloseHandle(1) close handle(2) deleteFileA(file.txt); Delphi prefered but would settle with other langs and convert my self. TIA

I'm attempting to uncompress and PECompact 2.XX file, and having a frustrating time. I followed a number of the tutorials here, but I think I'm missing some important stuff regarding the import tables. Here's what I've done: - Loaded .exe in IDA and saw junk - Used a hex editor to view the file, saw the "PECompact" string and knew it needed unpacking - Loaded .exe into ollydbg (using some stealth plugins) and found the signature PECompact "JMP EAX" instruction - Modified the JMP EAX to JMP EIP so it goes into infinite loop at that point - Ran the "infinite loop" version of the .exe, then attached to the process using ollydbg. Program is decrypted in memory! - The…

Hey guys, i am new to this forum but i have been looking at all the posts for the past day or two and i am just wandering if somebody could please help me, i enjoy reverse engineering and programming but yet i cannot seem to do a simple task using vb6 (i know i should be using c or c++ but i would like to use vb6 for this current project) i would like to create a serial sniffer like program using ReadProcessMemory and other APIs but for a beginner i would just like something simple like reading the display on calc.exe i did see a detailed tutorial posted here by root86 but every time i use PHandle = OpenProcess (PROCESS_ALL_ACCESS, False, pid) it just jumps to the error …

hello dears there is a program exe i want to change its functionality i want to read a text file in the same directory and put it in memory i am using ollydbg. program runs program states switchs to my code ---> my code reads text put in memory ---> return to the program state. what are the requirements i mean it has nice code cave what else? i appreciate if u can gimme the asm code which reads text and puts it in memory thanks.
