The FBI broadcast a warning to American businesses this week that said Iran might soon launch a cyberattack in the wake of President Donald Trump's decision to withdraw the United States from the Iran nuclear deal.
According to The Washington Free Beacon, the bureau's May 22 notice warned of potential attacks against business and government computer networks in the near future.
"The FBI assesses foreign cyber actors operating in the Islamic Republic of Iran could potentially use a range of computer network operations — from scanning networks for potential vulnerabilities to data deletion attacks — against U.S.-based networks in response to the U.S. government's withdrawal from the Joint Comprehensive Plan of Action (JCPOA)," the FBI wrote.
The Free Beacon reported the cyber bulletin provided a history of Iran's attacks and suspected attacks on computer networks over the years.
"From 2016 to 2017, malicious Iranian cyber actors conducted coordinated and broadly targeted intrusion campaigns against U.S. companies, academic institutions, and government entities," the FBI notice said. "The FBI encourages U.S. companies to report suspicious network activities to local FBI offices or FBI CyWatch."
Iran has stepped up its threats against the U.S. and its allies in the weeks since Trump's pullout from the Iran deal. A prominent Iranian cleric even threatened the destruction of two Israeli cities.
Cisco Systems, meanwhile, warned this week that a half million routers had been infected with malicious software and that a cyberattack against the Ukraine could be imminent.
