harry is analyzing inbound network traffic and notices a tcp packet that has the FIN, PSH, and URG flags set at the same time. which type of scan is most likely occuring?

The correct answer to the following question will be "Christmas Tree Scan".

Explanation:

Xmas scanners obtain their title from either the collection of flags switched on inside a document.

Such scans were intended to exploit the protocol header symbols of URG, PSH and FIN. Each OS reacts differently to Xmas packages that expose accurate information including port state, and much more.

So, it's the right answer.
