U.S. accuses China of massive hack on Microsoft's email system, other cyberspace intrusions

The Biden administration and U.S. allies on Monday blamed China for the massive hack on Microsoft's email system and other ransomware attacks.

In a coordinated announcement, the White House and governments in Europe and Asia identified China's Ministry of State Security, a secretive civilian intelligence agency, with using "criminal contract hackers" to conduct a range of destabilizing activities worldwide for personal profit, said a senior US administration official, according to CNN.

The Biden administration has been under intense pressure to response to a recent series of damaging cyberattacks on the U.S. 

Until now, much of the White House's public efforts have focused on Russia, including imposing new sanctions, CNN also reports.
