We are currently in the process of contacting MyNIC Bhd, the sole agency responsible for .my domain names in Malaysia for comment.
Update: MyNIC has a statement on their website at mynic.my: "We can confirm there was unauthorised redirection of www.google.com.my and www.google.my to another IP address by a group which called themselves TeaM MADLEETS.
The problem was alerted in the early morning and MYNIC Computer Security Incident Response Team (CSIRT) immediately started to resolve the issue. The domain name www.google.com.my has been restored to their correct information at 7.10 am today and www.google.my is still resolving.
At the moment, we are undertaking all necessary measures to monitor the situation and prevent further related issues."
