Iran Increases Cyber Attacks on U.S. Gov’t, Infrastructure: Cyber Security Firms

Iran has increased its offensive cyber attacks against the U.S. government and critical infrastructure as tensions have grown between the two nations, cyber-security firms say. In recent weeks, hackers believed to be working for the Iranian government have targeted U.S. government agencies, as well as sectors of the economy, including oil and gas, sending waves of spear-phishing emails, according to representatives of cyber-security companies CrowdStrike and FireEye, which regularly track such activity. It was not known if any of the hackers managed to gain access to the targeted networks with the emails, which typically mimic legitimate emails but contain malicious software. The cyber offensive is the latest chapter in the U.S. and Iran’s ongoing cyber operations targeting the other, with this recent sharp increase in attacks occurring after the Trump administration imposed sanctions on the Iranian petrochemical sector this month. Tensions have escalated since the U.S. withdrew from the 2015 nuclear deal with Iran last year and began a policy of “maximum pressure.” Iran has since been hit by multiple rounds of sanctions. Tensions spiked this past week after Iran shot down an unmanned U.S. drone – an incident that nearly led to a U.S. military strike against Iran on Thursday evening.
