Analyzing attacks taking advantage of the Exchange Server vulnerabilities - Microsoft Security

Microsoft continues to monitor and investigate attacks exploiting the recent on-premises Exchange Server vulnerabilities. These attacks are now performed by multiple threat actors ranging from financially motivated cybercriminals to state-sponsored groups. To help customers who are not able to immediately install updates, Microsoft released a one-click tool that automatically mitigates one of the vulnerabilities and scans servers for known attacks. Microsoft also built this capability into Microsoft Defender Antivirus, expanding the reach of the mitigation. As of today, we have seen a significant decrease in the number of still-vulnerable servers – more than 92% of known worldwide Exchange IPs are now patched or mitigated. We continue to work with our customers and partners to mitigate the vulnerabilities.

I am really excited to see 92% are protected and hope the rest would patch soon.
