Table of Contents

Are you a fan of the movie The Interview? Do you want to test your knowledge of cryptography in a fun and interactive way? Look no further! This CTF, built using Google Forms, is themed on the movie The Interview and challenges you to apply your knowledge of common cryptography concepts such as hashing, encoding, and hexadecimal representation.

Background

Released in 2014, The Interview is a comedy movie starring James Franco and Seth Rogen. The plot revolves around a fictional plot to assassinate the leader of North Korea, Kim Jong-un. The movie was highly controversial and sparked a lot of media attention.

The CTF

The CTF consists of three questions that will challenge you to apply your knowledge of cryptography concepts in a practical setting. To complete the CTF, you will need to use a tool called CyberChef. CyberChef is a web-based tool that allows you to perform a wide range of cryptographic operations, including hashing, encoding, and converting between different formats.

CyberChef

CyberChef is an open-source tool developed by GCHQ (Government Communications Headquarters) which is a British intelligence agency. It’s an easy to use, web-based tool that can be used for various tasks such as:

  • Hash calculation (MD5, SHA1, SHA256, etc.)
  • Encoding/Decoding (Base64, Hex, etc.)
  • File format conversion (JSON, CSV, etc.)
  • Data visualization (Hex dump, etc.)

It’s a very handy tool for anyone interested in cyber security, it’s highly recommended to use it to solve the questions in this CTF and for future reference.

Study Resources

To help you prepare for the CTF, here are some helpful links to articles on cryptography:

Conclusion

We hope you enjoy this CTF and learn something new about cryptography along the way. Remember to use CyberChef as a helpful tool and refer to the study resources to deepen your understanding of the concepts. Cryptography is an important aspect of cyber security and it’s always good to have a solid understanding of it. Good luck and have fun!
