Definitely a FIN scan, can't be anything else.

Wait, is he really using an Idle scan? That seems risky!

I think it's an ACK scan, not sure though.

I'm leaning towards the Idle scan because it uses a third party to avoid detection, but I might be mixing it up with another type.

I practiced a question similar to this last week, and I think the FIN scan was mentioned as a stealthy option. Could that be it?

I think the ACK scan is used to map out firewall rules, but I can't recall if that fits with the scan statistics shown here.

I remember studying different types of port scans, but I'm not entirely sure which one this is. The XMAS scan sounds familiar, though.
