Microsoft Exchange Server is top of mind for many organizations this March Patch Tuesday. The system count keeps rising for confirmed compromised on-prem Exchange Servers to the point where Microsoft extended update support to Cumulative Updates that were no longer supported. Bad news is updating the Exchange Server may not be enough. If your Exchange Server has already been compromised it must be rebuilt. Add in an Internet Explorer\Edge (HTML-based) Zero Day, a couple of Publicly Disclosed vulnerabilities and March Patch Tuesday could be a frustrating one.
