Pentagon cyberwarfare analysts are worried about a new wave of Iranian cyberattacks after President TrumpDonald John TrumpNew Bob Woodward book will include details of 25 personal letters between Trump and Kim Jong Un On The Money: Pelosi, Mnuchin talk but make no progress on ending stalemate | Trump grabs 'third rail' of politics with payroll tax pause | Trump uses racist tropes to pitch fair housing repeal to 'suburban housewife' Biden commemorates anniversary of Charlottesville 'Unite the Right' rally: 'We are in a battle for the soul of our nation' MORE announced Tuesday that the U.S. would exit the Iran nuclear agreement.

Within 24 hours of the announcement, researchers at security firm Crowdstrike reported a "notable" shift in Iranian cyberactivity, The New York Times reported. According to the Times, Iranian hackers sent emails containing malware to diplomats in the foreign affairs offices of U.S. allies and telecommunications companies.  

“With the nuclear deal ripped up, our nation and our allies should be prepared for what we’ve seen in the past,” former National Security Agency (NSA) Director Gen. Keith Alexander told the Times.

The NSA's former general counsel, Matt Olsen, said that Iran's cyber capabilities have increased faster than analysts had predicted. Olsen said those new capabilities could soon be aimed toward U.S. targets.

“[Iran] is now among our most sophisticated nation-state adversaries," Olsen told the Times. "We can anticipate those capabilities could well be turned against the U.S.”

More than a dozen sources contacted by the Times said they expected Iran to respond to Trump's decision with a new wave of more sophisticated cyberattacks.

“Given the history of Iranian cyberactivity in response to geopolitical issues, the American energy sector has every reason to expect some type of response from Iran,” Olsen said.

“We’re probably one of the most automated technology countries in the world,” Alexander added. “We are an innovation nation and our technology is at the forefront of that innovation. We could have a very good offense, but so do they. And unfortunately, we have more to lose.”

In 2013, Iranian hackers successfully breached computers controlling the Bowman Avenue Dam in New York.  Hackers, however, were unable to disrupt the dam's operations because it was under repair and offline. Iranian hackers took credit for the breach two years later.

Trump said Tuesday that his decision to pull the U.S. out of the Iran nuclear deal was motivated by a desire to stop sending Iran "empty threats."

“Today’s action sends a critical message: the United States no longer makes empty threats,” he said at a Tuesday ceremony at the White House. "[The deal] didn’t bring calm, it didn’t bring peace, and it never will."
