Iranian authorities have boosted their censorship efforts in a bid to crush opposition activity online. Authorities have tried to tamp down opposition activity by blocking opposition websites and other media. Anonymous is providing users with special advice forums and tools to fight the Iranian government’s censorship. The group has encouraged Iranian users to use distributed denial of service attacks (DDOS) in order to take down key government websites like khamenei.ir and leader.ir. The authorities are fighting back with high-tech monitoring and filtering equipment.
