If the system kernel is outdated (e.g., Ubuntu 18.04), known exploits like dirtycow or CVE-2021-3156 (sudo buffer overflow) might work. Always check uname -r .

Note: In the specific CCT2019 challenge, there is often a specific hint regarding "Cigarette" or "Smoke" malware.

Solution: Participants used tools like Nmap and Masscan to scan the network and identify open ports and services.

The investigation begins by identifying the profile of the machine from the memory dump. Without the correct profile, none of the forensic plugins will work correctly. cct2019 tryhackme
