The Foreign Ministry spokesman said Tehran has not backed cyber-attacks and it is a frontrunner in efforts to help counter cybercrimes.
"The Islamic Republic of Iran has never had dangerous measures in cyberspace on its agenda and does not support such moves," IRNA quoted Hossein Jaberi Ansari as saying in a statement on March 26.
Ansari was responding to the recent US charges against some Iranian citizens, accusing them of trying to disrupt its critical infrastructure by conducting cyber attacks.
Reuters reported on March 25 that the US Justice Department has indicted seven Iranian hackers, believed to be under the direct support of the Iranian government and the Islamic Revolution Guards Corps, for conducting cyber-attacks against several US banks, which have caused millions of dollars in damage, and trying to shut down a New York dam between 2011 and 2013.
It was the first time that citizens of a foreign country were being accused of mounting attacks against key US infrastructure.
The spokesman blamed the US government for carrying out cyber-attacks against Iranian nuclear facilities, saying the country lacks competence to accuse others of doing so, without providing proof.
"The US government, which had put the lives of millions of Iranians at risk of an environmental disaster by launching cyber-attacks against peaceful Iranian nuclear facilities, is not in a position to charge citizens of other countries, including Iran, without any documented evidence," he said.
The US government, along with Israel, was responsible for the 2010 cyber offensive against Iran, known as the Stuxnet, to undermine its nuclear capabilities.
The target of the attack was the Natanz uranium enrichment site, one of the two major Iranian nuclear facilities that housed thousands of centrifuges and tons of radioactive materials at the time.
"Severely suffered from sophisticated cyber-attacks with support of some governments, Iran has always been a leading player in collective international efforts against cybercrimes and it has been stressing the need for international regulations concerning cyberspace," he said.
