Image we got:

  1. What is this user's avatar of?

First, I tried to use exiftool to see what properties this image has.

This image seems to be attributed to someone named "OWoodflint", and I had it just sent to Google to check them out.

And from the results, I can get their Twitter, GitHub and blog.

So to answer the first question, the user's avatar is of a cat! :D

  1. What city is this person in?

I went to dig around their Twitter:

From here, I can get the BSSID for a wifi point near their house.

Entering it into Wigle.net, I could get the city they were in.

City: London

  1. What is the SSID of the WAP he connected to?

Still on Wigle.net, zooming in into the WAP could give the SSID.

SSID: UnileverWIFI

  1. What is his personal email address?

I looked around on his blog but didn't manage to get his email unfortunately, so I went on to the third link, which was his GitHub account.

Which on his README.md page, contains his email!

Email: [email protected]

  1. What site did you find his email address on?

Just GitHub :)

  1. Where has he gone on holiday?

I went back to his blog and found that he was in New York, which was where he had gone on his holiday.

  1. What is the person's password?

I was a little confused about this question because the hint was checking the source... BUT!

I have a dark reader chrome extension enabled which made me see the password immediately :") when it is supposed to blend into the white background. Oh well! :D
