Iranian and Chinese hackers have been aggressively targeting businesses and government agencies in the U.S. in what experts believe is a direct result of Donald Trump's foreign policy, The New York Times reports. Iran has been attacking American banks, businesses and government agencies much more extensively than previously reported, while Chinese hackers have been attempting to steal trade and military secrets from American military contractors and technology companies. Boeing, General Electric Aviation and T-Mobile were all reportedly targeted by Chinese hackers. While Chinese hacks tailed off four years ago after President Obama and Xi Jinping agreed a deal to stop attempting to steal trade secrets, the recent trade wars between the two countries are believed to have unofficially canceled the pact. Chinese hacks are at a similar frequency as they were previously, but are now much more sophisticated. Iranian hacks have stepped up since Trump's withdrawal from the 2015 nuclear deal.
