This Capture the Flag (CTF) challenge is a classic Open Source Intelligence (OSINT) puzzle. The goal is to act like a digital detective, piecing together publicly available information from an Instagram account to answer a series of specific security or "captcha" questions.
Here is a straightforward, step-by-step walkthrough of how to solve each question using the provided screenshots.
Question 1: What was the breed of your first dog?
Answer: basset hound
How to find it: Open the image named 3.jpg. Read the caption written by the user. Under her list of fun facts, the very first fact states: "Blue is a basset hound."
Question 2: When are you graduating? (mm/yyyy)
Answer: 06/2026
How to find it: You have to combine two pieces of information from the posts:
- The Month: In
1.jpg, the caption says she will be "home again in June." She also mentions June in3.jpg. - The Year: Look at the hashtags. She uses
#2026in1.jpg, and#classof2026in both2.jpgand3.jpg.
Putting the month (06) and the year (2026) together gives you the required format.
Question 3: What is the total number of siblings that your dog has?
Answer: 2
How to find it: Go back to the fun facts listed in the caption of 3.jpg. Look at fact number 3, which explicitly says: "Blue has 2 brothers..."
Question 4: What building gives your favorite view of SCU’s campus?
Answer: Kenna Hall
How to find it: This requires connecting a visual clue with an external search.
- First, identify the school. In
2.jpg, she uses the hashtag#gobroncos. A quick web search for universities with a "Broncos" mascot (combined with the initials "SCU" in the prompt) points to Santa Clara University. - Next, look at the photo of the campus in
1.jpg. By comparing the visual layout of those specific buildings, palm trees, and walkways against a campus map or Google Earth 3D view of Santa Clara University, you can triangulate the exact building the photo was taken from, which is Kenna Hall.
Question 5: Where will your dog be watching your graduation from?
Answer: grandma’s house
How to find it: Check the caption in 3.jpg again. Fact number 4 says: "Blue is gonna watch my graduation in June from grandmas house lol".
Question 6: Who’s the original voice actor of a pink friend in your favorite childhood TV show?
Answer: Koyalee Chanda
How to find it: This is a two-step trivia question based on profile clues.
- Identify the show: In
3.jpg, fact number 1 notes that her favorite show as a kid was Blue's Clues. - Identify the character and actor: The "pink friend" in the Blue's Clues universe is the character Magenta. A simple internet search for "original voice actor Magenta Blue's Clues" will lead you directly to Koyalee Chanda.
