SAN FRANCISCO — Iranian hackers targeted President Trump’s re-election campaign, two people with knowledge of the attacks said on Friday, in a sign of how cyberattacks could become a fixture of the 2020 presidential election.
Microsoft said in a report earlier Friday that hackers, with apparent backing from Iran’s government, had made more than 2,700 attempts to identify the email accounts of current and former United States government officials, journalists covering political campaigns and accounts associated with a presidential campaign.
It was not clear what information — if any — had been taken in the attack on the Trump campaign, according to the two people, who were not allowed to publicly discuss the investigation. While the Microsoft report did not name Iran’s targets, it found evidence that hackers had infiltrated email inboxes in at least four cases. But the four successful hacks tracked by Microsoft did not belong to a presidential campaign.
