MANILA/JAKARTA (Reuters) - Hackers claiming links to international activist group Anonymous defaced dozens of websites belonging to Australian businesses and Philippine government agencies on Sunday.
A group calling itself Anonymous Indonesia posted on Twitter a list of more than 100 Australian sites it had hacked, saying the action was in response to reports of spying by Australia.
The websites, defaced with a message reading "Stop Spying on Indonesia", are mainly owned by small Australian businesses and seemed to have been chosen at random.
