Based on the title "cct2019" on TryHackMe, this refers to the Cyber Challenge Thailand 2019 (CCT2019) CTF challenges. On TryHackMe, this typically appears as a series of forensic challenges created by stuxnet . Since this is a CTF (Capture The Flag) scenario rather than a linear narrative story, the "full story" is the walkthrough of how an investigator solves the case. Here is the full story and solution walkthrough for the CCT2019 Forensics challenges on TryHackMe.

The Case File: "The Incident" Scenario: You are a digital forensic investigator called in to analyze a compromised machine. An attacker has breached the network, and your job is to analyze the memory dump and artifacts to figure out what happened, how they got in, and what tools they used. Evidence Provided: A memory dump file (usually .raw or .vmem ).

Chapter 1: The Initial Reconnaissance Task: Identify the machine. 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. Investigation Steps:

The investigator loads the memory dump into Volatility (a standard memory forensics tool). They run the command to identify the operating system image info: volatility -f memory.raw imageinfo The output suggests the profile is Win7SP1x64 (Windows 7 Service Pack 1, 64-bit). cct2019 tryhackme

The Discovery: We now know the victim was running an older Windows 7 machine—likely vulnerable to modern exploits due to lack of patching.

Chapter 2: The Hunt for Malware Task: Find the malicious process. Attackers almost always leave a footprint in the running processes. We need to look for strange connections or processes masquerading as legitimate ones. Investigation Steps:

The investigator lists the running processes: volatility -f memory.raw --profile=Win7SP1x64 pslist The list looks standard (explorer.exe, svchost.exe), but one process stands out. There is a process running that does not belong to a standard Windows system, or an instance of cmd.exe with a strange parent process. Alternatively, the investigator checks network connections: volatility -f memory.raw --profile=Win7SP1x64 netscan The Breakthrough: The netscan output reveals an established connection to a suspicious external IP address on a high port. The process ID (PID) associated with this connection is identified. Based on the title "cct2019" on TryHackMe, this

The Discovery: The malicious process is identified. It is often named something innocuous to blend in, but in this challenge, it is frequently a payload generated by Metasploit (often named payload.exe or similar in the process list).

Chapter 3: Extraction of the Weapon Task: Dump the malicious executable. Now that we have the PID of the bad process, we need the actual file to analyze it further. Investigation Steps:

The investigator uses Volatility to extract the executable from memory: volatility -f memory.raw --profile=Win7SP1x64 procdump -p [PID] -D ./output The file is dumped to the output folder. Here is the full story and solution walkthrough

The Discovery: We now have the attacker's malware on our local disk. Opening it in a hex editor or running strings on it might reveal the path where the attacker dropped it (e.g., C:\Users\Admin\Desktop\... ).

Chapter 4: Persistence and Passwords Task: How did they stay inside? Attackers often modify the registry to ensure their malware runs every time the computer restarts. Investigation Steps:
