New York Post says some of its Twitter accounts hacked; UPI's Twitter also seems to be hacked

A New York Post spokeswoman says some of the newspaper's Twitter accounts were briefly hacked Friday.

The Twitter feed of United Press International sent out identical suspicious tweets Friday on false economic and military news.

The hack is being investigated, said Jenny Tartikoff, a spokeswoman for the Post. The New York newspaper is owned by News Corp.

It's the latest hack of a high-profile social media account. The Twitter and YouTube accounts of the U.S. military's Central Command were compromised earlier this week by hackers claiming to support the Islamic State militant group.

UPI, a news agency based in Washington, D.C., did not immediately respond to a request for comment.
