<p>I hope everyone is doing well!</p>

<p>07/28/2021 - Diary entry #314:</p>

<blockquote style="margin-top:0;margin-bottom:0">

<p>The PKPLUG group, also known as MustangPanda and HoneyMyte, is a chinese threat actor responsible for the Microsoft Exchange Server attacks in March, 2021. During these attacks, the group deployed a variant of the malware known as PlugX, named THOR.</p>
<p><br>
</p>
<p>THOR is a RAT and it was used as a post exploitation tool on one of the compromised servers. This variant has the ability to deliver other malicious payloads and it has several samples associated to the PlugX C&C infrastructure.</p>
<p><br>
</p>
<p>To bypass anitiviruses detections and the Microsoft Exchange servers, the group employed a technique called "living off the land", covered in our Daily Diary #247. It uses legitimate binaries, in this case the BITSAdmin, to download the malicious payload
containing the THOR malware.</p>
