Great explanation - really helped! 

[Can someone help with this PCAP file?]

Here is the file -

And a screenshot -

I have to analyse this file and answer several questions about it, like, small description of the events and weather this shows an attack,  but I'm new to Wireshark so I'm a bit lost.

If anyone could have a look and get back to me that would be great!
