Hackers have targeted Iranian infrastructure and communications networks, leading to disruption to Internet access across the country, according to reports.
The country increased cyber security following the attacks on its uranium enrichment centrifuges in 2010 by the Stuxnet computer worm, said to have jointly developed by the US and Israel.
Iranian High Council of Cyberspace secretary Mehdi Akhavan Behabadi was quoted by Iranian Labour News Agency as saying that the country had experienced heavy attacks against its infrastructure and communications companies, which has forced them to limit access to the Internet.
"Presently we have constant cyber attacks in the country," Behabadi said. "Yesterday an attack with a traffic of several gigabytes hit the Internet infrastructure, which caused an unwanted slowness in the country’s Internet.
"All of these attacks have been organised," he added. "And they have in mind the country’s nuclear, oil, and information networks."
In April, Iranian authorities reported that they detected a computer virus within the control systems of Kharg Island, which serves the majority of Iran’s crude oil exports.
Earlier the country had also reported cyber attacks on its nuclear facilities and claimed that the US, UK and Israel were behind the attack.
