Title: Microsoft releases monthly security update
Description: A new remote access trojan known as "PoetRAT" uses coronavirus-themed documents and emails to lure victims in. This was a previously undiscovered RAT. It uses two components to avoid detection by a single component. The dropper uses an old trick in a new way: It appends the RAT to a Word document. Upon opening the document, a macro is executed that will extract the malware and execute it. The operation seems to be manual, but it's streamlined to deploy additional tools as needed and to avoid unnecessary steps.
