The US reportedly launched a cyber attack on Iran in response to the downing of unmanned drone. Cyber security firms have also reported a rise in Iranian attempts to hack US government agencies and companies.
The United States launched an offensive cyber strike against Iranian missile control systems and a spy network this week amid escalating tensions between the two countries, US media reported on Saturday.
US President Donald Trump ordered US Cyber Command to launch the digital strikes on Thursday, The Washington Post reported.
Citing US officials, the newspaper reported that the attack crippled Iranian computers used to control rocket and missile launches.
The cyber attack came as the president held back from conducting airstrikes on Iranian targets in response to the downing of an US Global Hawk drone. Washington said the unmanned drone was in international airspace. Tehran said it was in its airspace.
Trump claimed he called off the conventional military strike after he learned 150 people would be killed and said it would not have been "proportionate." Instead, he said Saturday the US would announce new sanctions on Iran next week.
