[C] JmpFinder
by KOrUPt- 5 replies
- 4.2k views
Ok so this small project was inspired by a question from Illuz1on, so shouts to him for that one smile.gif. I didn't spend very long on this so it may contain a few bugs(hopefully not). Basically it searches a specified PE(Portable-Executable) for all JMPs to registers and informs you of their position on disk and in memory with the intention of aiding in the exploitation of executables. Those who are familiar with Windows exploits or exploits in general will already know why it's useful to know where a "Jmp ESP" or similar instruction is located in memory... So I wont bother explaining that part of things here. // JmpFinder V1.1 By KOrUPt #pragma comment(linker,"/BA…

Resuming a debugger after attaching to a target
by SuperCRacker- 6 replies

Hi I am trying to play a little bit with Win32 Debug apis. I tried to debug a target using the DebugActiveProcess API, the problem is that the target freezes right after and I can't resume its execution (I'm looking for the equivalent of F9 in OllyDbg). I tried many things ResumeThread, ContinueDebugEvent ... but no one worked. Maybe someone has got a suggestion Thanks, SC.

I'm currently coding an Olly plugin and it's supposed to read and write code from/to a given range of memory. While reading 2 sections in the image with just one call to Readmemory works flawlessly, Writememory with the same memory range returns 0 (= Error). I looked at the plugin manual but it doesnt say anything about restrictions on just one memory block. I also explicitly set the memory's access to PAGE_EXECUTE_READWRITE although I think Olly does that by default (at least temporarily), but to no avail Oh, regular WriteProcessMemory works fine... I just wanted to stick to Olly's APIs as it handles its BPs peroperly etc... Maybe someone has dealt with that beh…

Just finished some code for another site I visit. It's just been hacked together very quickly, though perhaps somebody will get some use from it. With error checking on the 4 calls to CreateFile or WriteFile you'd have an okay function. Shown below is the output from the code.

I was hesitated to which of the[request] or the [programming] to contribute. It questions here. The preservation function is not provided in this software. To add the preservation function, should I relate it to the value of Y coordinates and Z coordinates and X coordinates one by one? but, ‥ It is a very difficult thing for me. Can the [export] function be added to this software? Could you make the preservation function in [.Bvh] effective? Please give the answer to me.

Use Dll From Resource 1 2
by oricode- 25 replies
- 12.6k views
I am trying to bundle bassmod.net.dll along with a C# application. At present, I have included it in the resource and write it to disk upon execution.It works fine,but the problem is I can't delete the DLL upon app close. So I thought of using DLL directly from the resource. There is an article on codeproject.com, _http://www.codeproject.com/useritems/DLL_as_Embedded_Resource.asp ,but am not able to figure it out,how exactly is that supposed to be done with BassMOD.Net.dll(.NET API) . Any ideas other then this which could help me? Oricode.

C++ Arrays
by D1N- 4 replies
- 3.7k views
First, thanks to everyone for taking the time to answer and offer your explanations. I've been working with arrays in C++ recently. I've commented out the good code so you guys can compile it and produce these odd values and locations. When I use int mbox[5] = {10,20,30,40,50}; // normal init @10,20,30,40,50 -> mbox @0,1,2,3,4 things look great! but when I don't initialize anything the program produces random values and my question is two fold why and where do these random values come from? // main.cpp // This is a simple example of using arrays#include <iostream> #include <conio.h>using namespace std;int main() { // int mbox[5] = {10,20,30,40,5…

Modify FPU Without Detection
by stackwalker- 2 replies
- 3.4k views
Hi guys, i was wondering if there's any clever people out there that can help me with a little problem? I'm setting up a vectored exception handler in a certain target process and applying a DR Context breakpoint at the location which writes to the FPU. Upon recieving the exception in my handler i simply 'FLD <reg>' so my own float gets loaded into the FPU register, then overwrite 'EIP' to the next instruction. I was wondering if theres anyway to modify the register directly, or how to avoid the software detecting my Context modifications. I cant memory-hook the GetThreadContext api at the application level because it detects it. I was wondering if a DR breakpoint …

Hi I need help for my OllyPlugin i read in the Pdk from olly this ***** Returns pointer to element with specified index in sorted data sorted by actual criterium, or NULL on error.

MZ-Crypt v1.0 decryptor
by bigboss-62- 1 reply
- 3.8k views
Hello guys... A few days after my BJFnt decryptor, i'm proud to bring you my MZ-Crypt v1.0 decryptor. There is a very important bug in the cryptor (including its original decryption engine). It (de)crypts one byte more than the raw size of current section, so it can encrypt an uncryptable section, resulting in a crash of crypted program. This decryptor does in the same way, in order to get original file before this one was crypted. I have also included source code in masm for those who are interested... See you soon in my next decrypter... Perhaps decruncher/unpacker if enough time... Laurent aka BIGBOSS from COPs Added 10-02-2008: The crypter itself CPS_MZCry…

Yohoo hord of fans, a few days after DEF decryptor, here is PingvinCrypt decryptor. PingvinCrypt was interesting to study, a nice SoftIce antidebug and a header access. This cryptor uses a xor decryption, with the key based on a CRC of header firsts 100h bytes and decrypter bytes. The import decryption is the same key xor 13h Tested with PingvinCrypt v1.0... As usual, source code in masm and cryptor are also included for interested ones... See you soon ... Laurent aka BIGBOSS from COPs PingvinCrypt_v1.0.zip CPS_UnPingvinCrypt_v1.0.zip
