Msert Tool Is Able to Find and Remove the Web Shells for Exchange Server

Microsoft products are one of the most exploitable things that are currently available on the software market. People who use it constantly not only meet different bugs, but also risk getting their systems infected through the vulnerabilities. MS Exchange Server – a quite popular mail server – is full of such security breaches.

Is it really so bad?

In March 2021, Microsoft reported about four Exchange Server vulnerabilities that were used to perform the cyberattack. In fact, those security breaches can easily be used to steal the email (that can easily contain sensitive information), and inject various other malware. Here is the list of those exploits:

This bulk of vulnerabilities is called “ProxyLogon”. It was used by the Chinese government-backed hacker groups that were aiming at corporate espionage – reading the emails, harvesting the credentials and even collecting the personal information about employees. In process of these attacks, hackers used the following web shells:

Is it possible to avoid the exploitation of these vulnerabilities?

Sure, all of these viruses are already added to the detection databases of Microsoft Defender. Last one got a very big update in Windows 11, so its detection capabilities rose significantly. It will be extremely attentive with exploitable apps, and Exchange is just one of them. Along with updating the Exchange Server with the last security patches, it will create a perfect shield at your network.

For the companies who decided to use the separate anti-malware tools (not Microsoft Defender), Microsoft released a stand-alone tool, called MSERT. It is, exactly, the alter-ego of the Defender – but without the proactive protection and several security features that were applied with Windows 11 release. Nonetheless, no one can help you to deal with the Microsoft products’ problems better than Microsoft itself.
