Hacker group Anonymous has hacked and defaced Turkish government websites in protest against internet filtering rules to be introduced in Turkey in August.
In a posting on piratebay.org, Anonymous claims to have stolen data from more than 100 websites in Turkey and replaced 74 government websites with protest messages.
The group indicated the action was part of a campaign by hackers, called Anti Security (AntiSec), to steal and leak classified government and company information to expose security flaws.
"Accessing and participating in the free flow of information is a basic human right. Anonymous will not stand by while the Turkish government violates this right. We will bring our support to circumvent censorship and retaliate against organisations imposing censorship," the message said.
