The CCT2019 room is not your typical beginner-friendly Capture The Flag (CTF) challenge. It's a legacy collection of challenges originally created for the , sponsored by the US TENTH Fleet. It is currently available on TryHackMe as a "Legacy" challenge for the community to hone their skills.
Trigger the shell and get a (e.g., www-data ).
Using OSINT (Open Source Intelligence), a quick search reveals that "Angela Bennett" is the protagonist of the 1995 movie "The Net". In the film, the password BER5348833 is found. This is the key to decrypt the encrypted file transfer.

: Rather than guessing the slider values, read the mathematical formulas or conditional statements directly within the decompiled C# source window to determine the precise values. Flag Acquisition
Search the file system for the first user flag, typically located in the home directory of the low-privileged user. Phase 4: Privilege Escalation
: Extract the raw application layer bytes. The outcome of this correct extraction yields a protected executable or key file. Step 3: Reverse Engineering the re3 Binary

After catching the reverse shell, you will likely operate as a low-privileged user (such as www-data ). Your next goal is to stabilize the shell and find the user flag. Upgrading the Shell

: Adversaries frequently wrap reverse shells in custom encryption layers to bypass standard Signature-based Intrusion Detection Systems (IDS). Security operations must rely on protocol anomaly detection to flag non-compliant traffic on common ports.
Now, the challenge involves deep analysis of the extracted pcap_chal.pcapng file.
