Sekarang kita punya dan password bersama dengan username dari pengguna DVWA yang berarti database dan aplikasi tersebut telah jebol sepenuhnya. | Seperti yang bisa kita lihat dari gambar di atas sqlmap berhasil menghack password hash pada kolom password dan berhasil memecahkannya dengan menggunakan dictionary attack.

Seperti yang bisa kita lihat dari gambar di atas sqlmap berhasil menghack password hash pada kolom password dan berhasil memecahkannya dengan menggunakan dictionary attack. Sekarang kita punya dan password bersama dengan username dari pengguna DVWA yang berarti database dan aplikasi tersebut telah jebol sepenuhnya.
Penutup
Dalam tutorial ini kita melihat seberapa efektif alat sqlmap ketika kita harus mengidentifikasi dan memanfaatkan kerentanan injeksi SQL. Tentu saja cara yang tepat untuk memanfaatkan kerentanan SQL Injection secara manual. Namun dalam banyak tes penetrasi karena kendala waktu penggunaan sqlmap adalah perlu.
Khususnya dalam hal ini sqlmap berhasil mengemerasi database dengan sukses dan mengekstrak data dari tabel database dengan sangat cepat. Tentu saja sqlmap memiliki lebih banyak kemampuan seperti itu yang bisa mengecek adanya WAF (Web Application Firewall), IDS dan IPS. Karena bisa menjalankan perintah sistem operasi. Untuk semua alasan ini alat ini harus berada di toolkit setiap penetrasi tester.
