Hackers compromise AP Twitter account

NEW YORK (AP) — Hackers compromised Twitter accounts of The Associated Press on Tuesday, sending out a false tweet about an attack at the White House.

The false tweet said there had been two explosions at the White House and that President Barack Obama was injured. The attack on AP's Twitter account and the AP Mobile Twitter account was preceded by phishing attempts on AP's corporate network.

The AP confirmed that its Twitter account had been suspended following a hack and said it was working to correct the issue. The fake tweet went out shortly after 1 p.m. and briefly sent the Dow Jones Industrial Average sharply lower.

AP spokesman Paul Colford said the news cooperative is working with Twitter to investigate the issue. The AP has disabled its other Twitter accounts following the attack, Colford added. At no time was the AP news wire compromised.

Asked about the incident at a press briefing, White House spokesman Jay Carney said the President is fine.

"I was just with him," Carney said.
