Report: TryHackMe CCT2019 Challenge Analysis
4. Flags Summary
| Flag Type | Location | Method |
|-----------|----------|--------|
| User flag | /home/mandy/user.txt | SSH login as mandy with cracked password |
| Root flag | /root/root.txt | Cron job privilege escalation |
Conclusion
The TryHackMe CCT2019 room is more than just a CTF – it’s a condensed simulation of a real penetration test engagement. It forces participants to abandon hand‑holding, rely on their enumeration skills, and chain multiple vulnerabilities across a segmented network.
For anyone preparing for certifications like eJPT, OSCP, or PNPT, CCT2019 serves as an excellent self‑assessment. Completing it without walkthroughs demonstrates solid proficiency in intermediate‑level offensive security.
Note: As with all TryHackMe rooms, ensure you have permission to attack the target systems. CCT2019 is a legal sandbox environment provided for educational purposes. tryhackme cct2019
Phase 5: Privilege Escalation (From User to Root)
This is the core challenge of tryhackme cct2019. You have a shell, but you can't read root.txt. Here is the typical escalation vector:
Step A: Find SUID Binaries Run:
find / -perm -4000 2>/dev/null
Look for unusual binaries that aren't standard (e.g., /usr/bin/zip, /usr/bin/find, or a custom binary). Report: TryHackMe CCT2019 Challenge Analysis

Step B: GTFOBins to the Rescue
If you see /usr/bin/find, check GTFOBins. The find command with SUID allows you to execute commands as root.
/usr/bin/find . -exec /bin/sh \; -quit
This spawns a root shell.
Alternative Vector (Path Hijacking):
Sometimes the room uses a custom script that calls a system command without an absolute path (e.g., service apache2 restart instead of /usr/sbin/service). If you can write to a directory earlier in $PATH, you can create a malicious binary named service that spawns a shell. Note: As with all TryHackMe rooms, ensure you
Room Difficulty & Stats
- Difficulty: Medium
- Category: CTF / Boot2Root
- Learning Objectives: Web app security, SQL Injection, Command Injection, SUID binaries, Path Hijacking.
- Time Estimate: 60–120 minutes for experienced users; longer for intermediates.
Phase 3: Steganography & Forensics
This is often the most popular section of CTFs. It involves hiding data inside innocuous-looking
CCT2019 on TryHackMe is an "Insane" difficulty, legacy room based on the 2019 U.S. Navy Cyber Competition Team assessment. It focuses on rigorous forensic analysis, requiring accurate traffic reconstruction and deep binary analysis rather than simple flag hunting.
