If you use an on-premises Microsoft Exchange Server, it is important to reach out to your IT Support immediately to be sure updates are installed to boost your cybersecurity and protect against recently discovered critical security vulnerabilities. The vulnerabilities allow an attacker to compromise your network and steal information, encrypt data for ransom, or even execute a destructive attack. It has been reported that over 30,000 organizations in the U.S. have been attacked due to these issues since Microsoft announced the issue on March 2, 2021.
Details for business leaders and instructions for IT Support can be found on the U.S. Department of Homeland Security’s Cybersecurity & Infrastructure Security Agency website https://us-cert.cisa.gov/remediating-microsoft-exchange-vulnerabilities as well as Microsoft’s Security Response Center https://msrc-blog.microsoft.com/2021/03/02/multiple-security-updates-released-for-exchange-server/
