Hi Guys, I've recently written some code in C which searches for a 40-bit key used to encrypt a known plain text. The code works and is able to find a known key to find for a given cipher text. The trouble is that is that rate of keys searched is very low, say 4-5,000 keys/sec. Despite running this on an old PC (Athlon XP 2200+) I know I should be seeing much faster results. For example, using APDFPR as a benchmark, I can see an average rate of 1.7x10^6k/s. My compiler settings (GCC and VC6) are optimised for speed and for my processor. I've also replaced the array subscripting with pointers as I remember reading that this is a faster method. Neither of these made any …

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…

[Native/C] Reading keyboard input
by Saduff- 0 replies

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
by snoopy- 2 replies
- 7.8k views
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
by Dave Prost- 5 replies
- 8.5k views
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 ? As in PEiD, just copy the plugin into the plugin folder and the plugin will be working. Same thing I want to do. 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. Thanks

Coding unpacker
by snoopy- 8 replies
- 194.5k views
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…
