The clues given to us are
"Sam has parked his car in front of a store. Find the name of the store."
and we were also given a .pcap file
I've uploaded a copy of the .pcap file here
First thing i did was load the .pcap file into Wireshark and check whether there are any file objects and i saw just 1 image.
http://regex.info/exif.cgi to check for GPS information.
Surprisingly there is indeed GPS information and Google Maps as shown below
Making use of Google Maps's Street View, i found this.
Ok and the answer to this challenge is..... "Wells Fargo" :D
