Merhaba ben de bir şey merak ediyorum. Bu dos saldırısında ellerine ne geçiyor yapan kişilerin?

Wireshark ile izleyin hocam. IP adresini bu linkte aratın. Eğer sizin adresiniz ise bilgisayarınızda malware olabilir.

Aynı sorunu sıklıkla ben de yaşıyorum, çözebildiyseniz yardımcı olur musunuz?

DoS saldırısı aslında kolay halledilebilecek bir durum. Statik IP kullanmadığınızı varsayıyorum. Bu saldırının malware kaynaklı olabilme olasılığı yüksek. Malware, IP adresiniz değişse bile yeni IP adresinizi saldırı yapan kişiye bildiriyor olabilir. Öncelikle sisteminizi Hitman Pro, Emsisoft Emergency Kit gibi güçlü antivirüs motorlarını kullanan araçlarla tarayabilirsiniz. Daha sonra router'ı kapatın 10 saniye bekleyin ve tekrar açın. IP adresiniz değişecektir. Yazdığım programlarda tarama sonuç temiz çıkarsa, Norton Security gibi güçlü IPS imzaları olan bir güvenlik yazılımı kurabilir sonucu test edebilirsiniz. Saldırı olduğunda Norton Security engelleyecek ve bildirecektir. Ayrıca, router'ı fabrika ayarlarına resetleyebilirsiniz. Router'da firewall özelliğinin açık olduğundan emin olun. Router ayarlarından Wi-Fi ve arayüz şifrelerinizide değiştirmenizi öneririm.

Emniyet Siber Suçlar'dan destek alabilirsiniz.

Nasıl tespit ediliyor bilmiyorum fakat, Tespit edildikten sonra adresine kadar bulabiliyorsunuz yapan kişiyi, dava açabilirsiniz. Yanlışım varsa bu konuda affola.

Evet dava açılabiliyor.

ICMP Flood olarak geçiyor saldırının türü, güvenlik duvarından yankı isteğini engelledim ama yine de iş görmedi.
