Part 1: The Windy City OSINT Challenge

This challenge is in association with The CyberSleuth Chronicles. Please read the following directions on how to participate.

Instructions for the Challenge:

There are three separate challenges all themed with The Windy City - Chicago. The images are provided in the questions below.

Submitting answers:

Use the images to complete the challenges. An answer key is provided at the link above. Please be sure to read the notes on the submission form to ensure your answers are captured accurately. We are not collecting your email addresses.

Use your OSINT skills to piece together the puzzles, some are easy while others are not so straight forward. Each image corresponds only to the challenge associated with its number. You do not need to download or install anything. You can complete every challenge with only a browser.

How to use provided images:

Each of the three challenges uses one image and they are titled, respectively.

Challenge #1 == building1

Challenge #2 == building2

Challenge #3 == building3

The buildings do not relate to the other challenges.

For example, you will not use building2 to answer any questions for Challenge #1 or #3. However there are clues at the end of Challenge #1 and #2. You should leverage these clues to help answer the next challenge.

How clues work:

Challenge #1 ends in a clue for Challenge #2 and Challenge #2 ends in a clue for Challenge #3. Challenge #3 has no clue for any other challenge.

Use the clue to help answer the next challenge in sequence, 1>2>3. The clue will not help you answer the current question. For example, the clue at the end of the Challenge #1 will not help answer Challenge #1 nor #3 but will help answer Challenge #2.

Hopefully, I’ve explained how to successfully participate in this guide.

If you have any questions, please reach out via The CyberSleuth Chronicles Discord server. -@HackinKraken
