0Sasaki-Haise/Umbral-Stealer ? reverse-engineered prompt

Build me a Windows security awareness demo in C# that shows how risky software can collect sensitive info, but keep it safe and local only.

I want a simple app with a builder and a payload, where I can customize the app name, icon, and assembly info, then run it on a test machine and see a report of what it would have gathered, like basic machine details, browser related data placeholders, webcam and screenshot access prompts, and startup or anti VM checks for demonstration only.

Don’t actually steal passwords, cookies, tokens, wallet data, or send anything anywhere. Instead, make it log fake or redacted results locally so I can use it to explain the dangers in a lab or classroom. If you need any current C# or Windows docs, look them up online first.
