Hey everyone, its been a long time since i was last here so sorry if it is in the wrong section. I am pretty new to Lua and its not my language of choice but its the only language this program allows so i am stuck. I am trying to open a website using shellexecute in Lua but no matter what i do, i don't seem to get any results when the script runs. I have been googling for hours now and there were a few good reads but apparently i am the only one who is using shellexecute to open website or maybe no one else has this problem, there were a few examples using native os function (os.execute) but they didn't seem to work either for me, it just opened a cmd window w…

does someone of tuts4you know how to disable/remove the "dll can load" (IMAGE_DLLCHARACTERISTICS_DYNAMIC_BASE) in programming code? we know this IMAGE_DLLCHARACTERISTICS_DYNAMIC_BASE is equal to 0x40, so is it a correct way to substract 0x40 from the DllCharacteristics? so in example NTheader->OptionalHeader.DllCharacteristics = NTheader->OptionalHeader.DllCharacteristics - 0x40;

NonIntrusive Debugger Library
by Nieylana- 17 replies
- 7.1k views
Hey all, It has been a long time since I posted to this forum,but I wanted to post here to this .NET library known to people who may find use of it. The name of the project is NIDebugger (for non-intrusive debugging). There are currently 2 variants, NIDebugger (x86) and NIDebugger64 (x64). The main page for the x86 project is here: http://tslater2006.github.io/NIDebugger/ Currently the x64 is experimental and can be found via the github repository: http://github.com/tslater2006/NIDebugger64 Because of the experimental state of the x64 library, I will only discuss the x86 one... One of the most simple examples of using it is shown below, ple…

Hi everyone, Some time ago I put this small utility together for a friend that needed it. Turns out to be a useful piece of code. Code was found on the internet, only slightly modified and cleaned up a little. Credits to the original author of the code (sorry, couldn't find the website I found it on). This is the code: #include <stdio.h>#include <windows.h>void ErrorDescription(DWORD p_dwError){ HLOCAL hLocal=0; FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM|FORMAT_MESSAGE_ALLOCATE_BUFFER, 0, p_dwError, MAKELANGID(LANG_ENGLISH, SUBLANG_ENGLISH_US), (LPTSTR)&hLocal, 0, …

using this http://downloads.securityfocus.com/vulnerabilities/exploits/48179-poc.c and this http://blog.csdn.net/whispermemory/article/details/6754144 We could create a lil KRNL Scanner w/ Dev-C++ .. Getting the Module.ImageName is tricky, and if anyone has any suggestions? Another thing, dunno if its because of the token adjustment but, this scanner finds a few more sys drivers in the krnl in comparison to a module scanner that uses strictly: ZwQuerySystemInformation( SystemModuleInformation #include <windows.h> #include <stdio.h>#include <iostream>using namespace std; #define NT_SUCCESS(Status) ((NTSTATUS)(Status) >= 0) typedef enum _SYSDBG_COM…

Even if i set ollydbg to stop at system EP the hook is still there at entrypoint. Is this a usermode or kernelmode hook?

Wanted to ask a question before I wasted 20 bucks trying it myself on a fun project. I have some SPI sensors I want to get info from. A friend gave me a linux eval board w/SPI sensor soldered to the eval board, and I could see the SPI device in /dev, open it up and get any info I needed from the resigters on the SPI sensor. I'd like to know if I can take a device like this - http://www.ftdichip.com/Products/ICs/FT220X.html Plug the SPI sensor into the USB stick, then plug the USB stick into a Rasberry PI or other device that accepts USB... And using the free USB drivers, open a Windows COM port or linux open() function & talk directly with the register…
