U.S., NATO and EU to blame China for cyberattack on Microsoft Exchange servers

A new joint effort made up of NATO member states, the European Union, Australia, New Zealand and Japan is coming together to confront the global threat posed by Chinese state-sponsored cyberattacks.

In its first action on Monday, the countries will publicly blame China’s Ministry of State Security for a massive cyberattack on Microsoft Exchange email servers earlier this year.

The attack was carried out by criminal contract hackers working for the MSS who also engage in cyber-enabled extortion, cryptojacking and ransomware, the official said.
