A global attack on the popular Microsoft Exchange email server system has become a global crisis.
This hack became public knowledge on March 2, 2021, with Microsoft releasing multiple software patches to address vulnerabilities that hackers were exploiting.  Microsoft and other groups are referring to the originating hacking group as “Hafnium.”
