Breton - OSINT - Cyber Siege 2023

Hint: What time and location did I last ping on last year’s Valentine's Day? Fun Fact: Last time I checked I had 1437 pounds in my account and I was tagged in 2020.

Flag Format is AOF{xx_xx_xxAM_XXXXXXXXX}

Now, the challenge asks us to find the location and time when the shark last pinged on Valentine's Day. Now we know that Valentine's Day is on 14 February every year. We are told that we are finding last year's ping. this means that our date becomes 14 February 2022.

Lets research what website tracks shark activities.

Let's find location of Breton shark.
