A hacker named as AlpHaNiX attacked on some high profile websites Google, Gmail, YouTube, Yahoo, Apple, Microsoft, Hotmai, linux, samsung and taked down the website with a deface page for some time with the help of DNS cache poisioning attack. All websites are hacked on domain .cd wich belongs to Democratic Republic of Congo.
