The Microsoft patch is not guaranteed to apply correctly, the bad actors had a head start, and the complexity of these servers makes detection difficult. Even if the patch was successfully applied, there‘s still a 1–in–5 chance that malicious code infected your servers before the patch was released. And if you DID NOT apply the patch immediately, you are almost certainly compromised.
Most Managed Services Providers and Internal IT Teams do not have the security tools available to them to catch the IOCs (Indicators of Compromise) that may still reside on your on-premises Exchange Server.
Even if your team has already deployed the Microsoft patch, you may still be vulnerable. We can quickly validate whether or not your Exchange Server is vulnerable to this exploit.
We can provide preliminary validation within one business day, and a deeper analysis within 24 – 48 hours to validate whether your Exchange Server and all your corporate email and attachments are exposed.
