Default Google Bug!


İlgililer'in dikkat'ine...


Merhaba;

Büyük arama motorlarindan biri olan google.com da ilk bakışta ufak bir
hata fakat bir saldırgan olarak düşünüldüğünde,
search butonunda tahmin edemeyeceğiniz kadar ağır bi yoğunluğa neden
olabilecegini dusundugumuz bir ddos açığı tespit edildi mantıksal
olarak düşünürsek,
aynı anda 50 kullanıcı aynı sorguyu kullandığında sadece
hissedersiniz birde kötü niyetli birinin aynı anda 2000 3000 user
veya botnet ile
bir saldırı yapabileceği düşünülürse durum gerçekden ciddi sonuclar
doğurabilir tabi görmeden bu açığı hiç kimse ile paylaşmadığımızı
belirtirim
şimdi örneklendirme yapalim..
