Microsoft says hackers linked to the Iranian government have targeted a U.S. presidential campaign, as well as government officials, media targets and prominent ex-patriate Iranians.
The company declined to identify the campaign, citing privacy concerns.
Corporate vice president for security Tom Burt says in a blog post Friday that owners of four accounts that were successfully breached have been notified. He says those accounts that were compromised were not related to U.S. campaigns or officials.
He says the attacks by a group Microsoft calls Phosphorous occurred during a 30-day period in August and September.
