Description

There should be something hidden inside this photo... Can you find out?

Solution Approach

Core idea: Identify the weakness from source review or fingerprinting first. Iterate with incremental payloads instead of guessing.

Steps

1. First, unzip the .zip file given.

2. Let's check the file type.

3. Let's strings it.

4. Notice there's a strings that looks like a hash (?) Let's assume it's md5 since it's the common one in CTF.

5. Let's try to crack it with online md5 cracker.

6. Hmm.. Not the flag, but a string.

7. What comes to my mind is, we shall use steghide to extract hidden file's inside since the string could be the pass.

8. Let's try it.

9. Nice! Exactly as what we thought.

10. Now, strings the .txt file.

11. Might be encoded in base64, let's try to decode it anyway.

12. Got the flag!

Flag
