Description

As a red team member, I want a ransomware simulation that changes the desktop wallpaper, in order to more accurately simulate ransomware attacks in my network.

Acceptance Criteria

• Ransomware simulation changes the wallpaper on Windows systems.
• New wallpaper clearly states that this is a ransomware simulation, not real ransomware.
• The ransomware simulation can be configured so that changing wallpaper is disabled.
• Ransomware configuration screen includes a checkbox that allows the user to enable/disable changing the wallpaper.
• Unit tests are written and provide comprehensive coverage.
• Documentation is written that describes how the wallpaper functionality behaves.
