Notice how the script builds commands dynamically using variables; focus on identifying how it reassembles string literals or executes the final payload (often look for trailing characters or execution tokens like . or &). Alternatively, try passing the clean string variables into a PowerShell console or a script block logging environment where you can safely change the final execution command to a simple echo/print statement to see the final, deobfuscated string.

Fantastic technique Sam! Never thought of that.
