This via Bloomberg. I find it interesting that the political rhetoric is about China, but the attacks are seen to be coming from Russia…:
Russia-based hackers are responsible for the majority of nation-state attacks on Microsoft customers, according to new data from company.
Microsoft Corp. has issued 13,000 alerts about nation-state hacking attempts to its customers in the last two years, with 52% of incidents between July 2019 and June 2020 related to Russian hackers — whose targets have ranged from elections to the Olympics, according to a report published Tuesday. Iran was responsible for a quarter of the alerts while China was responsible for 12%. The remainder of the nation-state activity observed by Microsoft came from North Korea and other countries.
