The Enigmatic Manuscript - CTF Challenge Writeup

Challenge: The Enigmatic Manuscript
Points: 50
Category: Cryptography

Objective

The objective of The Enigmatic Manuscript challenge is to uncover a hidden flag concealed within an image. Your task is to utilize cryptographic techniques to decipher the flag hidden within the image.

Solution

To successfully complete The Enigmatic Manuscript challenge, follow these steps:

1. Image Analysis:

   • Begin by examining the provided image. In this challenge, images often hide clues or messages within their metadata or content.

2. Exiftool Inspection:

   • Use the exiftool utility to inspect the image’s metadata and content for any hidden information.

3. Base64 Encoding:

   • Upon using exiftool on the image, you may discover a base64 encoded message within the image’s metadata or content.

4. Message Decryption:

   • Decode the base64 encoded message to reveal the hidden flag.

5. After following these steps and decoding the base64 message, you will successfully uncover the flag concealed within the image.

Flag

The flag for this challenge is in the format: petgrad2023{XXXXXXXXXX}.

In The Enigmatic Manuscript challenge, your cryptography skills come into play as you decode the base64 message hidden within the image to unveil the flag. Best of luck!
