The U.S. Department of Homeland Security and the Justice Department are investigating a claim that personal data related to thousands of DHS and FBI employees was hacked and has been posted online, an agency spokesman said on Monday.
The tech website Motherboard reported on Sunday that a hacker, who Motherboard said wished to remain anonymous, intended to release the names, job titles, email addresses and official phone numbers of over 9,000 DHS employees and another 20,000 Federal Bureau of Investigation workers.
The SITE Intelligence Group, which monitors militants' media activity, on Monday said a pro-Palestinian Twitter account on Sunday had posted a link to a document that contained 9,372 purported DHS employees' data.
