This is definitely a challenge. I've been trying to create an difficult to crack login-system because it seems incredibly difficult to do. I mean, many login systems out their can be detoured by a single jump, and I wanted to challenge myself to create something which can try and avoid the easy detour of user login. Heres what I planned to do, please point of flaws and suggest some ideas. Login: Client which the user enters login details into. If the login details checkout with the server, the server will generate a hash based on the current time (to the day), the username, and the password, return it, and store it in the user's registry. This hash is hereby called the Us…

I'm writing a native application in C (/SUBSYSTEM:NATIVE) and need to check if a key combination was pressed. It works, but it only captures the first packet of keyboard input data (i.e only first key pressed), however I need to check 4 keys simultaneously. Here's the code I used for testing: UNICODE_STRING NtReadKeyboardInput() { LARGE_INTEGER Interval; UNICODE_STRING input; UNICODE_STRING keyboardDeviceName; OBJECT_ATTRIBUTES objectAttributes; IO_STATUS_BLOCK ioStatusBlock; WCHAR show[200]; NTSTATUS status; HANDLE keyboardHandle; UNICODE_STRING message; KEYBOARD_INPUT_DATA inputData[3]; USHORT usMakeCode; USHORT usFlags; //----------------- …

Loader and Exception Handling

Hey guys, I was wondering if anyone has experience with using a loader to create a process and install an exception handler. The thing I want to figure out if possible is to let the loader be the exception handler. I know SEH is per thread used so that would mean I would have to inject a DLL for example and install the exception handler. I was wondering if it is possible to use a Loader program which uses: CreateProcess API and install an exception handler to it. So when exception in program occurs it goes to handler from the loader. Best regards.

hey, i need to have a simple c++ gui, using the msvc++2008pro IDE. It`s just a small project, so i didnt want to bring wwwidgets or similar into the game... Since the build-in resource editor doesnt display the location and size of single dialog items (for unknown reasons...) i was looking for an alternative and came across this: ResEdit 154 - http://www.resedit.net/ That resource editor is awesome...unfortunately, its generated .rc scripts are not compitable with msvc++2008pro, even though the homepage says different: Adding a simple dialog resource created by ResEdit crashes msvc++: // Generated by ResEdit 1.5.4 // Copyright (C) 2006-2010 // http://www.resedit…

Adding Custom Login

Hi I have a compiled app that I want to add a login program too. I've written the login program and compiled it. My first thought was adding a code cave but when I look at the login assembly it's pretty big so I'm not sure if there will be enough space for a code cave. Is there a better way? Can I merge the two programs together and then maybe make a jump at the start of the first program to go to the login app? Then depending on the return value continue loading app 1 or exit. I'm just guessing here as i'm really not sure of the best way to proceed so any hints or tips would be greatly appreciated. Thanks D

Hi all, I am coding next version of Hash calculator and I am thinking to add support for PEiD plugins. I know that PEiD plugins have two main calls LoadDll DoMyJob But, what I want to know is that, how to dynamically load the dlls present in the folder of Hash calculator ?

Just copy the plugin to the Hash calculator folder and the plugin will be working with calculator. How to do this ? Oh, one more thing, I am coding in MASM, so codes in assembly will be more useful.

Coding unpacker

Hey Guys, Recently got into the nice field of coding unpackers instead of using WinDBG scripts/ plugins. What I am facing is something that has to do with coding a import reconstructor. I am simply testing it on a UPX protected file to get a good understanding. IAT on my original unprotected file is at 41410C (VA). When the file is packed the PEheader is being changed to RVA 17A94 (417A94) this is a fake IAT address. Now what I am trying to do is figuring out how to code a tool to rebuild it for me. So I first need to find the real IAT. I read that Imprec could use 2 techniques: signature scanning, API 'hooking'. When I signature scan for FF25 [Jmp Address] I am able to f…
