This week there is a new critical alert that requires the mission-critical community’s immediate attention.
Microsoft released several security updates due to targeted attacks against vulnerabilities found in Microsoft Exchange Server (versions 2013, 2016, and 2019). Though the attacks appear to be limited, Microsoft is urging the immediate updating of all affected systems to mitigate the vulnerabilities and further abuse within networking environments where Exchange servers are being used. Microsoft attributes the activity to a cyberattack group known as “Hafnium.”
