Center to Investigate Organized Crime (CIOC)
"The CIOC was established by Iran’s IRGC for the purposes of protecting the Government of Iran in the cyber realm. During the June 12, 2009 presidential election in Iran, the CIOC helped the Iranian Government censor websites and identify opposition activists. For example, CIOC issued a communiqué on June 17, 2009, urging website managers to block “content that incites the population to riot and spread threats and rumors.” CIOC also helped identify internet users who published material insulting government officials and questioning the elections; some of these individuals were subsequently arrested by government agencies." 1
