How can an attacker automate the deployment of a WLL backdoor using PowerShell?

The article provides a PowerShell script that base64-encodes a compiled 3KB DLL (e.g., calc.dll) and stores it in a variable. The script then decodes and writes the DLL as a `.wll` file to the Word Startup folder. This automation allows the attacker to deploy the backdoor without manual file placement, making it efficient for mass exploitation.
