描述

Describe the bug

Ransomware's wallpaper change feature for Windows sets the wallpaper with the same fit (stretched, filled, etc) that is already set on the system. This may result in some of the text in the wallpaper image being cut.

To Reproduce

Steps to reproduce the behavior:

  1. On a Windows machine, change the wallpaper fit to "Fill".

  2. Start the Island, enable the ransomware wallpaper change option in the Island.

  3. Run the Agent on the same machine.

  4. Check the wallpaper.

Expected behavior

All of the text should be readable. This could be fixed by changing the fit of the wallpaper.

研究方向
Investigate the code responsible for setting the wallpaper in the ransomware module (likely in a file related to Windows wallpaper). The issue suggests that the current implementation uses the system's existing wallpaper fit setting. To fix, modify the code to explicitly set the wallpaper fit to 'Stretch' or a fixed option that ensures text is not cut. The fix should be tested on Windows with various system wallpaper fit settings.
