The attackers transferred a file on port 4444. Using cryptcat with the extracted key decrypts the file:
: It’s a pcap challenge. If you’re doing stego or re, you’re either down a rabbit hole or there’s an easier way. HINT2 : It is very important to do the first step correctly. If you don’t recover the first file in its entirety, you may not be able to complete steps later on. HINT3 : On the final step, this was built to run in an amd64 Kali Linux environment. If you are using a different Linux distro, you may run into some problems. tryhackme cct2019
Later tasks involve complex decryption methods. You might find yourself using sites like Cryptii to work with Enigma M4 "Shark" ciphers or performing OSINT on YouTube to find passwords for Railfence-encrypted files. The attackers transferred a file on port 4444
The CCT2019 is structured as a narrative-driven challenge. Unlike standard "boot-to-root" machines, this event was divided into specific "Tasks," each acting as a standalone puzzle. The difficulty curve ranges from beginner-friendly logic puzzles to intermediate technical challenges. HINT2 : It is very important to do the first step correctly
