WASHINGTON (AP) _ The FBI is investigating more than $12,000 in calls to the Middle East and Asia that were made when a hacker broke into the Federal Emergency Management Agency's phone system 10 days ago.



The hacker made more than 400 calls on a FEMA voice-mail system in Emmitsburg, Md., on Aug. 16 and 17. FEMA said it appears that a "hole" was left open by the contractor when the voice-mail system was being upgraded. A FEMA spokesman said the gap in the system has since been closed.



"We are investigating it," FBI spokesman Jason Pack said Tuesday. "We are working with FEMA to get to the bottom of it."



One security expert called this type of hacking low-tech and "old school" — something that was popular 10 to 15 years ago.



Afghanistan, Saudi Arabia, India and Yemen are among the countries that calls were made to. Most of the calls were about three minutes long, but some were as long as 10 minutes.
