Many High Profile websites in Pakistan Defaced by DNS hack

Few hours back, I reported that Google Pakistan has been hacked and defaced by Turkish hackers. They used DNS hack to change the DNS records of google.com.pk to pint it to the malicious deface website.
I also reported that DNS server has been compromised to perform this hack. If they have the access to the DNS server, they can deface any website having .pk domain.
Now they are doing this one by one. We recently got news that most of the high profile Pakistani websites have been defaced. These are the main websites.
- http://www.google.pk/
- http://www.google.com.pk/
- http://www.yahoo.pk/
- http://www.sony.pk/
- http://www.blogspot.pk/
- http://www.coca-cola.pk/
- http://www.paypal.pk/
- http://www.microsoft.pk/
- http://www.apple.pk/
- http://www.hp.com.pk/
We should also expect more the be hacked because DNS server is still in hackers hand. They can change DNS records of any website to point to the deface page hosted on some free hosting.
A users on twitter with handle @postsgoogle tweeted that 284 .pk domains has been hacked with the above methods.
