Iranian and Chinese hackers appear to have resumed attacks on U.S. businesses and government agencies, The New York Times reported Monday. The recent targets of Chinese spies included Boeing, General Electric Aviation, and T-Mobile, according to an intelligence briefing summary read to the Times. Security experts believe that the hackers stepped up their efforts after President Trump withdrew the U.S. from the Iran nuclear deal last year, and as trade tensions escalated with China. Iran's recent attacks have been broader than previously reported, targeting U.S. banks, businesses, and government agencies and prompting the Department of Homeland Security to declare an emergency order during last month's government shutdown.
