The Secret Service and Fox News are investigating a series of attacks early Monday on one of the news network’s Twitter feeds, FoxNewspolitics, in which hackers erroneously said that President Obama had been assassinated in Iowa. The six messages were taken down several hours — around noon today — after they were posted. Fox News Digital General Manager Jeff Misenti says the company has asked Twitter to conduct a “detailed investigation” into the incident and to come up with “measures to prevent future unauthorized access into FoxNews.com accounts.” A student newspaper at the State University of New York at Stony Brook said that an anti-corporate group called The Script Kiddies claimed responsibility and may hit Fox News again. Here’s Fox News’ statement about the attacks:

FoxNews.com’s Twitter feed for political news, FoxNewspolitics, was hacked early Monday morning.

Hackers sent out several malicious and false tweets claiming that President Obama had been assassinated. Those reports were incorrect, of course, and the president was spending the July 4 holiday with his family at the White House.

The tweets have been removed from the feed.

FoxNews.com alerted the U.S. Secret Service, which is declining public comment. Jeff Misenti, vice president and general manager of Fox News Digital, said FoxNews.com was working with Twitter to address the situation as quickly as possible.

“We will be requesting a detailed investigation from Twitter about how this occurred, and measures to prevent future unauthorized access into FoxNews.com accounts,” Misenti said.

FoxNews.com regrets any distress the false tweets may have created.
