Chinese hackers attack Microsoft, rumors that more than 20,000 U.S. organizations have been hacked

White House Press Secretary Jen Psaki likewise said earlier Friday, “This is a serious breach that could have far-reaching implications, and we are concerned about the large number of victims.”

Records show that organizations located in Asia and Europe have also been affected, although the Hackers‘ actions were mainly focused on the United States.

Microsoft 5 refused to comment on the scale of the impact of the wave of hackers, saying only that it is working with the government and security companies to provide help to customers.

The group of hackers, allegedly from mainland China, used four vulnerabilities to hack Microsoft’s email server software “Exchange Server”, which stole the contents of some users’ emails, but also installed malicious software to build an environment that can be invaded for a long Time. Microsoft called the hacker group Hafnium.
