''*CYBER'' ATTACKS COUNTER*''

EXPERTS WARN of Iranian cyberattacks : With nuclear deal off, hackers are seen as likely to retaliate against the U.S.

Inside the Pentagon's cyberwarfare unit analysts have been closely monitoring Internet traffic out of Iran.

Six thousand miles away, Israel's elite cyberintelligence team Unit 8200, has been running war games in anticipation of Iranian strikes on Israeli computer  networks.

Government and private-sector cybersecurity experts in the United States and Israel worry that  President Trump's decision to pull out of the Iran nuclear deal some weeks ago will lead to surge in retaliatory cyberattacks from Iran.

Within 24 hours of' Mr. Trump's announcement that the United States would leave the deal, researchers at  CrowdStrike, the security firm, warned customers that they had seen a ''notable'' shift in Iranian Cyberactivity-

Iranian hackers were sending emails containing malware to diplomats who work in the foreign affairs offices of United States allies and employees at telecommunication companies, trying to infiltrate their computer systems.

And security researchers discovered that Iranian hackers, most likely in an intelligence-gathering effort, had been quietly examining Internet addresses that belong to the United States military installations in Europe over the past two months.

Those researchers would not  publicly discuss the activity because they were still in the process of warning the targets.

Iranian hackers have in recent years demonstrated that they have an increasingly sophisticated  arsenal of  digital weapons . But since the nuclear deal was signed three years ago, Iran's Middle Eastern neighbors have usually been those hackers targets.

Now cybersecurity experts believe that list could could quickly expand to include businesses and infrastructure in the United States.

Those concerns grew more urgent last week after Israeli Fighter jets on military targets in Syria, in response to what Israeli said had been a rocket attack by Iranian forces.

''Until today, Iran was constrained,'' said James A. Lewis, a former government official and cybersecurity expert at  Center for Strategic and International Studies in Washington.

''They weren't going to do anything to justify breaking the deal. With the deal's collapse, they will inevitably ask : ''What do we have to lose?''
