One day after The New York Times reported that Chinese hackers had infiltrated its computers and stolen passwords for its employees, The Wall Street Journal announced that it too had been hacked.

On Thursday, The Journal reported that it had been attacked by Chinese hackers who were trying to monitor the company’s coverage of China. It said hackers had broken into its network through computers in its Beijing bureau.

In a written statement, the business newspaper owned by News Corporation described the attack as an “ongoing issue” and said it was working closely with authorities and security specialists to clean up its systems. It said that it completed a “network overhaul” on Thursday in an effort to rid its systems of hackers.

China’s Ministry of National Defense has denied any involvement in the cyberattack at The Times or any other American corporations.
