# Description
|
| 7 |
+
> Detailed description as it would need to be explained to other lab members
|
| 8 |
+
|
| 9 |
+
The goal of the challenge is to be able to solve three related problems about three different cybersecurity topics such as: steganography, WiFi Cracking and esoteric languages (programming).
|
| 10 |
+
|
| 11 |
+
# Deployment
|
| 12 |
+
> Any special information about the deployment if there is a server component
|
| 13 |
+
|
| 14 |
+
The .jpg is the only file needed for deployment. This is an offline challenge.

# Solution
|
| 20 |
+
> As detailed as possible description of the solution. Not just the solver script. As full a description as possible of the solution for the challenge.
|
| 21 |
+
|
| 22 |
+
The ideal solution for the challenge should be to:
|
| 23 |
+
- Analyze the metadata of the image and observe the Title field.
|
| 24 |
+
- Decode the base64 Title field.
|
| 25 |
+
- Extract with any stego tool the .zip hidden inside the file using the password decoded from the b64 above.
|
| 26 |
+
- Decompress the .zip hidden file and get the handshake and animal files.
|
| 27 |
+
- Realize that one of the files is not only an animal sound, it is also code written in COW, an esoteric language.
|
| 28 |
+
- Copy/paste the code into a COW interpreter and observing that the result is a link to an online dictionary word.
|
| 29 |
+
- Decrypt the WiFi handshake file available using the above dictionary and any WiFi cracking tool.
