A group of hackers believed to be linked to the government of Iran tried to access email accounts associated with a U.S. presidential campaign, Microsoft announced Friday.

The company said that it had seen "significant cyber activity" from a group of hackers that it believes "originates from Iran and is linked to the Iranian government."

Microsoft said that its threat tracking operation found the group attacked 241 email accounts associated with current and former U.S. government officials, journalists, prominent Iranians outside Iran and one U.S. presidential campaign. Microsoft did not name the campaign that was attacked.

The company said that the attack on the campaign was unsuccessful but that the hackers were able to access four accounts not associated with the campaign or the current and former government officials.
