This Proof of Concept requires Microsoft Windows PowerShell 7+.
As of the time of this release, I will leave it up to your imagination. Once this PoC has been around for awhile, this will be filled in accurately.
The transition from PowerShell version 5 to version 7 marked a significant improvement in the language's capabilities. In version 5, handling arrays and complex byte assembly posed challenges, limiting its ability to execute payloads like InvisInk effectively. However, with the upgrade to PowerShell 7, these limitations were addressed. The new version enabled the integration of complex arrays seamlessly, allowing for the execution of InvisInk payloads without revealing the underlying code while also skipping the decoy code.
