What are the red flags?

• The address of the sender is sssss@gmail.com (it should have been PayPal.com)

• The body of the message says "Hey ... this is not a professional message.

• There is very little in the body only saying to see attached file. I do not recommend looking at attached files of messages with red flags, but I did pull it up to see what additional red flags are to be found:

• The wording of the message is clear that English was not the person's native language. It is also very non-professional.

• There is an urgency (you only have 48 hours to respond)
