Microsoft Exchange vulnerability
3/23/2021 A serious vulnerability in Microsoft Exchange was discovered in early March. As the CERT team at the National Center for Cybersecurity (NCSC) announced, “several hundred” Swiss organizations have been compromised.
We at PageUp AG reacted quickly and took the necessary steps for all of our customers and installed the necessary security patch. If a server was affected, in addition to building a new Exchange server, we also recommend monitoring the client and server infrastructure using MS Defender for Endpoint in order to detect subsequent attacks caused by lateral movement within the Active Directory.
Unfortunately, the danger is still not completely over the world. As F-Secure has now found out, the vulnerability still exists on almost every second server. That is why we are happy to have closed the gap quickly to protect our customers.
Do you have any questions about the security gap or would you like more detailed information about MS Defender for Endpoint, then we would be happy to take the time to discuss this with you.
