Instructions

We can get into the Administrator's computer with a browser exploit. But first, we need to figure out what browser they're using. Perhaps this information is located in a network packet capture we took: data.pcap. Enter the browser and version as "BrowserName BrowserVersion". NOTE: We're just looking for up to 3 levels of subversions for the browser version (ie. Version 1.2.3 for Version 1.2.3.4) and ignore any 0th subversions (ie. 1.2 for 1.2.0)

Hints

Where can we find information on the browser in networking data? Maybe try reading up on user-agent strings.

Solution

Special Agent User was a lot like Digital Camouflage. I did not use the same TCP Stream even though I had just finished Digital Camouflage, because I honestly didn't realize that the browser would show in there, I guess I didn't look hard enough. I searched for a "GET" tag in the info and found one right away. When I looked into it, I found what I was looking for right at the top: Firefox/25.0 ... except I didn't realize it. I don't remember exactly what the flag was, but I do remember how difficult it was to figure out the exact way it was supposed to be entered.
