The Website of Word's most popular mobile messaging app and Antivirus Firm - AVG were hacked this morning and defaced by a new Palestinian Hacker group - KDMS Team, affiliated with Anonymous Group.
The Defacement page titled 'You got Pwned', with Anonymous Logo and playing Palestinian national anthem in the page background, says:
we want to tell you that there is a land called Palestine on the earth
this land has been stolen by Zionist
do you know it ?
Palestinian people has the right to live in peace
Deserve to liberate their land and release all prisoners from israeli jails
we want peace
and "There Is No Full Security We Can Catch You !"
It seems that the hacker used DNS hijacking to point domains on a fake server with deface page. The Whatsapp has resolved the issue, but at the time of writing AVG is still defaced. It is not clear that if any user data was compromised from AVG or Whatsapp.
We have contacted WhatsApp and AVG for comment and will update this story when we hear back. Just two days before, KDMS Team hacked LeaseWeb, one of the world's biggest hosting company.
Update : Another Antivirus Firm 'AVIRA' website also defaced by hackers, just few minutes before.
Update: NETWORK SOLUTIONS, LLC is common Domain Registrar for AVG, Avira and Whatsapp . Possibly, hacker compromised the Domain Registrar and modifies the DNS settings to perform DNS Hijacking.
