[Z3r0 C00l Bruh!] --- Question: --- Hackers keep secrets. Answer --- 1. We are presented a file with the name "hackers.jpeg" 2. After running some diagnostic on it e.g strings, we can see that there is something off with the headers of the file ![alt text](https://i.imgur.com/95Ote39.png) 4. As I've done a lot of stego my self, this is obviously used with steghide, as it presents these headers / hexinfo 5. I unlocked the hints as my bruteforce didn't go as planned in terms of extracting the embedded file 6. After i while, i thought why not try "neverlanctf" for the password of the picture 7. steghide extract -sf hackers.jpeg --passphrase neverlanct ![alt text](https://i.imgur.com/9q4TPMl.png) 8. Cat the output of the file "Ohno.txt" presents us with the following: I wonder what this is???? Fowbjcsniuwcwscotsxvevvko 9. Firstly i thought it was base64 (it was not) 10. Secondly i thought it was a caesar cipher / rot 13 (it was not) 11. Thidrdly i thought it was a Viginere cipher 12. It was a Viginere with the password "hackers" (as the hint gave us "what are they") ![alt text](https://i.imgur.com/Ag2OGOh.png) The result of the decryptet message: Yourflagismyfavoritemovie 13. Tried first "Yourflagismyfavoritemovie" 14. Tried second "myfavoritemovie" 15. Success! Comment: --- hint1: Most CTF keys are the name of the CTF but not all. hint2: What Are they?
