You can download & execute very easily a Koadic zombie using the stager regsvr
In the Shells folder, there are a lot of different shells. To download and execute Invoke-PowerShellTcp.ps1 make a copy of the script and append to the end of the file:
is a portable and secure Netcat alternative. It works on Unix-like systems and Win32. With features like strong encryption, program execution, customizable source ports, and continuous reconnection, sbd provides a versatile solution for TCP/IP communication. For Windows users, the sbd.exe version from the Kali Linux distribution can be used as a reliable replacement for Netcat.
Example xsl file :
You can use this technique to bypass Application Whitelisting and Powershell.exe restrictions. As you will be prompted with a PS shell.
Just download this and execute it:
You can download a basic C# reverse shell from here:
PS console with some offensive PS modules preloaded (cyphered)
PS console with some offensive PS modules and proxy detection (IEX)
