The US has responded to a recent rise in Iranian cyber-activity and the shooting of an unarmed drone last week by launching cyber-attacks against Iran’s military IT systems. From a report: The cyber-attacks were carried out by US Cyber Command with the direct approval of US President Donald Trump, the Associated Press reported on Sunday, citing two inside sources, and confirming the report through a third Pentagon official. US Cyber Command targeted the Iran military’s computer systems used to control some of the country’s rocket and missile launchers. The systems are managed by Iran’s Islamic Revolutionary Guard Corps (IRGC), a branch of Iran’s Armed Forces, which the US Presidency designated as a terrorist organization last year. The AP reported that the US cyber-attacks were the second go-to measure after President Trump backed off from launching a military strike against Iranian military and radar bases last week, on Thursday.
