The Washington Post reported on Wednesday that hackers had broken into their servers and gained access to employees' usernames and passwords.
Employees were asked to change their usernames and passwords although it wasn't clear how much of the company data was compromised. Hackers also did not get access to the Post's publishing system, subscriber information, or sensitive employee information such as emails and Social Security numbers, officials said.
This is the second time in three years the Washington Post's servers have been hacked.
In both instances, the company's suspicions have been directed to Chinese hackers. In this case, the intrusion lasted for a few days, according to an ongoing investigation.
