Question 1

How do I use PSReflect to call a Windows API function?

Accepted Answer

Define the function in memory using PSReflect's methods, specifying parameters and return types, then invoke it directly in PowerShell. The module provides templates, but you'll need to reference Win32 documentation for accurate definitions.

Question 2

PSReflect vs using Add-Type in PowerShell – what's the difference?

Accepted Answer

Add-Type compiles C# code, potentially leaving disk artifacts, while PSReflect uses pure reflection without compilation for better stealth. However, Add-Type might offer better performance for repeated calls due to compilation.

Question 3

Is PSReflect safe to use in production environments?

Accepted Answer

While powerful for automation, its dynamic nature can introduce instability; it's best suited for security research or administrative scripts, not mission-critical systems without extensive testing.

Question 4

Can PSReflect bypass antivirus detection?

Accepted Answer

It reduces disk artifacts through in-memory execution, but modern EDR tools may still detect reflective API calls, so it's not foolproof and should be used ethically in authorized testing.

Question 5

What are some practical examples of PSReflect in red teaming?

Accepted Answer

Common uses include process injection, token manipulation, and direct system calls for lateral movement, leveraging its stealth to avoid dropping tools on disk during assessments.

Question 6

How to install and set up PSReflect module?

Accepted Answer

Install via PowerShell Gallery with 'Install-Module -Name PSReflect' or clone from GitHub, then load it using 'Import-Module PSReflect' to start defining in-memory types and functions.
