Antivirus mitigates one of the four zero-day exploits found on Microsoft Exchange servers.
Microsoft has released a security update for Defender Antivirus to mitigate the CVE-2021-28655 Exchange Server vulnerability through a URL rewrite configuration. Antivirus scans the server and undoes changes made by known threats.
Redmond released several security patches after it was discovered that a malicious attacker was using four zero-day exploits to perform a ransomware attack on Exchange Server. Security exploits affect Microsoft Exchange Server 2013, 2016, and 2019.
Microsoft Defender WillMitigate Exchange Server Exploit
Of the four zero-day vulnerabilities, the one patched by Microsoft (CVE-2021-28655) is the most serious because it acts as an entry point for the other three exploits. According to Microsoft, Defender Antivirus automatically assesses whether Exchange Server is vulnerable to exploits and applies fixes as needed.
However, Microsoft said in a security blog that this interim mitigation is a temporary solution and that companies and businesses around the world will take longer to install the latest Exchange cumulative updates. .. This is just to address the vulnerability completely.
Exchange security updates are the most comprehensive way to protect your server from these attacks and other attacks that have been fixed in previous releases. This interim mitigation is designed to help you protect you while you spend time implementing the latest Exchange Cumulative Updates for your version of Exchange.
If Microsoft Defender is installed on an Exchange Server that has auto-definition updates enabled, the mitigation will be applied automatically. If your organization manages definition updates for Microsoft Defender, you need to make sure that a new discovery build (1.333.747.0 or later) is deployed to Exchange Server.
If you don’t use Microsoft Defender, you can use the single-click mitigation tool that Microsoft released for Exchange Server last week to protect against ProxyLogon vulnerabilities that affect tens of thousands of customers.

Microsoft Exchange Servers around the world are targeted by ransomware attacks
Since the Hafnium hacking group first exploited the ProxyLogon vulnerability, Microsoft Exchange servers around the world have been the target of ransomware attacks. The problem is so serious that Homeland Security has declared a Microsoft Exchange attack an “emergency”.
The Hafnium group has created an attack vector by combining four zero-day vulnerabilities. This allows an attacker to target the server with crypto mining malware, web shells, and even DearCry ransomware.
Acer was also hit by a $ 50 million ransomware attack from the REvil ransomware group using the same Exchange Server exploit.
