Looking For A Good Fraud Data Set For A Class Project, Not Very Knowledgeable.

i somehow ended up in a data analytics class where I need to prepare a proposal for an investigation related to fraud and the prof has basically given us no insight. I need a data set that i can run at least three different supervised or semi-supervised analytical techniques on. I was thinking something related to spam email but i really don’t know what I’m looking for. Struggling to come up with good ideas. preferably simple, any help is greatly appreciated
