# PatriotCTF 2024 - Give me four words, Vasily
**Title:** Give me four words, Vasily

**Description:** We have been tracking a highly suspicious submarine believed to be harboring many enemy skiddies. Unfortunately, this satellite image is rather out of date. Your mission is to locate the submarines there using a more up-to-date image, and tell us what class they are with their NATO reporting name - a letter from the NATO phonetic alphabet, spelled out.

We want to know precisely where the aft end of northernmost submarine attached to the pier is. Communicate its location in three words. Include the NATO reporting name of the class of submarine in your answer.

Submission format: PCTF{three.position.words.class_name}

Example submission: PCTF{employing.broken.imports.sierra}

## Solution:
I began by performing a reverse image search in hopes of locating similar visual features to those highlighted in the original image:


This eventually led me to a website which, when translated, had the headline: [India may lease Russian Navy's Kilo-class submarines](http://rybachii.blog84.fc2.com/blog-entry-1029.html). As I scrolled down, I found the same place in an image. With the `class_name` now identified from the title, the next step was to pinpoint the location. Fortunately, the same webpage also included the geolocation of the site.:


Entering the GPS coordinates in [what3words](https://what3words.com/) and now all I had to find where the aft end of northernmost submarine attached to the pier is:


And that's the last part of our flag: `bagels.light.vivid`, adding them all, this is our final flag:
`PCTF{bagels.light.vivid.Kilo}`
