So basically your binary is just a string in the PowerShell script. The function Invoke-ReflectivePEInjection (part of the Powersploit project).Click on Patch and wait for the file to patch. Choose the UPS file you want to patch and for this example, we’ll be using Pokemon Gaia. The EXE converted to string created in point 1 Choose the base game that we will be patching, and for this example, we have FireRed once again.$Base64String = ::ToBase64String($ByteArray) Ģ. Ensure that you have permission to the file, and that the file path is correct."

You can use Invoke-Expression to interpret strings as PowerShell commands.

This is also a way to avoid escaping all the special characters, especially in advanced attacks involving several steps to deliver the payload.

You can use base64-encoded commands to obfuscate your evil commands, making the attack a little less obvious to spot.

No need to install anything on the target.Using PowerShell to run malicious code has many advantages, including: I was trying to resolve an issue with creating a pure PowerShell payload as part of a client-side attack.
