From Exif information I got 2 informations :

  • Copyright : OWoodflint
  • GPS Position : 54 deg 17′ 41.27″ N, 2 deg 15′ 1.33″ W

Doing some google search i found 3 interesting site

  • WordPress site
  • Github project
  • Twitter account

The First site was a wordpress blog

From the blog we have

  • Nickname : owoodflint
  • Name : Oliver Woodflint
  • Actual position : New York

The actual position is confirmed by the GPS coordinates from exiftool

Using the actual position I was able to answer the question

Where has he gone on holiday?

The second site was a Github repository

Now we have more information about Oliver

  • Nickname : owoodflint
  • Name : Oliver Woodflint
  • Actual position : New York
  • Email : OWoodflint@gail.com
  • Twitter Account : @OWoodflint
  • From location : London

From there i was able to answer to the folowing questions

  • What city is this person in?
  • What is his personal email address?
  • What site did you find his email address on?

I checked the commits but noting interesting

The last site was the twitter account

Immediatelly I was able to respond to the first Question of the challenge 😉

What is this users avatar of?

One of the tweets show a BSSID (The mac of a wireless access point)

  • B4:5D:50:AA:86:41

I started looking for information that i can grab using the BSSID i got

I used the Wigle because it’s allow to do recon using the BSSID as a filter

From wigle.netI was able to identify the SSID of the Wifi network

  • Wifi SSID : UnileverWIFI

So I was able to answer to the question

Whats the SSID of the WAP he connected to?

The last question was

What is this persons password?

For this part i focused on the on site i did not recon yet (the blog).

As usual, I always start looking into the code, many leaks can be founded somtime

After searching I founded a white text hidden inside the index page

Bingo, It was the answer to the last question

Enjoy 😉
