On Saturday, Google Bangladesh appeared to have been hacked. When some users went to the Google site, they saw a message from the TiGER-M@TE hacker group that the site was taken over.
It looked like this:
Reports came in at the Google Webmaster Help forum where we learned the issue was around DNS servers being taken over and some users who replied on those DNS servers were being taken from Google.com.bd to this hacked version.
The DNS server was restored soon later and Google returned for these Bangladesh searchers.
Google itself was not hacked, it was the servers that controlled where users went when they typed in google.com.bd that was hacked.
