Four million current and former federal employees may have had their personal information hacked, the Office of Personnel Management said on Thursday.

The agency, which is conducts background checks, warned it was urging potential victims to monitor their financial statements and obtain new credit reports.

U.S. officials believe this could be the biggest breach ever of the government's computer networks.

The breach is beyond the Office of Personnel Management and Department of Interior, with nearly every federal government agency hit by the hackers, government officials said.

An assessment continues and it is possible millions more government employees may be impacted.

American investigators believe they can trace the breach to the Chinese government. Hackers working for the Chinese military are believed to be compiling a massive database of Americans, intelligence officials told CNN on Thursday night.
