Human Connection Challenge: Season 1 – Scanning Walkthrough Guide (Official Version)
Time’s Up! Congratulations to everyone who completed Lab 2: Scanning from the Human Connection Challenge: Season 1. In this walkthrough, I'll share some strategies for efficiently completing the lab, based on my perspective as the author. Remember, there are often multiple ways to approach a challenge, so if you used a different method and succeeded, that's perfectly fine! The goal is to learn, and I hope these notes help clarify any steps and reinforce key concepts for the next challenge. This challenge has now ended, but the lab remains available for practice. While prizes are no longer up for grabs, you can still complete the lab and use this walkthrough guide for support if needed. I’ve also used placeholders in some of the commands that would give away an answer directly, so if you see anything enclosed in angle brackets, such as <name server>, please make sure you replace it with the actual value, such as nameserver. With all that considered, let's get started. Overview Task: Identify the name server records of tinytown.bitnet. 1. What is the IP of the first name server for tinytown.bitnet? You’ll first need to open a Terminal on the Kali desktop. Next, you’ll need to query the DNS Server IP (found in the Machines panel) about the tinytown.bitnet domain using the nslookup (Name Server Lookup) tool. You’re specifically looking for NS (Name Server) records, so you can use the -type=ns parameter with nslookup to specify this: nslookup -type=ns tinytown.bitnet [DNS Server IP] The output of this command will return two name servers for the domain labelled with 1 and 2. Your next step is to identify what IP address is associated with the first name server (1). To do this, you can use nslookup along with the name server, domain, and DNS Server IP: nslookup <name server>1.tinytown.bitnet [DNS Server IP] This command will then return an IP address for the name server. 2. What is the IP of the second name server for tinytown.bitnet? As you’ve already identified both name servers, you’ll just need to run the previous command, except with the second (2) name server: nslookup <name server>2.tinytown.bitnet [DNS Server IP] You’ll then find the IP address associated with it. Task: Identify port service information for Target 1. 3. What service version is running on port 53? A network scanning tool like Nmap can help you identify the service version running on a specific port. To do this with Nmap, you can use the -sV option for service detection: nmap -sV [Target 1 IP Address] The output will show what service version is running on port 53. 4. What is the full service banner of port 22? There are a couple of ways to find the full service banner of port 22 – such as with Nmap or Netcat. If you’re using Nmap, you can modify the previous command to include the “banner” script along with the port number: nmap -sV -script=banner [Target 1 IP Address] -p22 The command line will then display the service banner from port 22. You can alternatively use netcat to manually connect to the SSH server. When a client connects, Netcat may present a banner that contains version information. To use Netcat, you’ll need the nc command along with the Target 1 IP address and specify you want to connect to port 22: nc [Target 1 IP Address] 22 When you run this command, the banner appears before the terminal hangs. Task: Identify a token on one of the ports. 5. What is the token? With the previous Nmap command, you initially found that three ports were open on Target 1. However, you’ll need to do a more thorough network scan to find another open port, one not initially found with the previous scans. To do this, you can expand your port scan to cover a much wider range by using Netcat to scan for open ports from 1 through 9000: nc -zvn <Target 1 IP Address> 1-9000 Here, -z will scan for listening services but won’t send any data, -v is verbose mode, which provides more detailed information, and -n tells Netcat not to resolve hostnames via DNS. This command will reveal a fourth open port. Now, you can use Netcat to connect to this port: nc <Target 1 IP Address> <open port> The token will then be displayed in the terminal. Task: Scan the TLS configuration on Target 2. 6. How many protocols are enabled? To scan for SSL/TLS configurations, you can use the sslscan tool. By default, sslscan scans port 443 and will return supported server ciphers, certificate details, and more. You can use sslscan like this: sslscan <Target 2 IP Address> The returned output will be verbose, but you can find and count the number of enabled protocols under the SSL/TLS Protocols subheading. 7. Name an enabled protocol. Using the previous output, name one of the enabled protocols. 8. What exploit are the protocols NOT vulnerable to? Using the same output, scroll down through the results until you find a subheading that’s named after a vulnerability and contains a similar string to: <Protocol> not vulnerable to <vulnerability name> The vulnerability has the same name as the subheading. Task: Identify and extract information from an SMB share on Target 3. 9. What Disk shared directory can you access? To extract information from an SMB (Server Message Block) share, you can use the smbclient tool. First, you’ll need to list the SMB shares on the target using the -L flag (the list/lookup option) with: smbclient -L //<Target 3 IP> You’ll then be prompted for a password, but you can press Enter to skip this. A list of SMB shares will then be displayed, three of which are shown to be a Disk type, so you know the answer will be one of these. You can now begin to go through the list and try to connect to the shares with: smbclient //<Target 3 IP>/<Sharename> However, this time when you’re prompted for a password and you press Enter, you might encounter a message when you try and connect to a share: NT_STATUS_ACCESS_DENIED If you attempt to connect to all shares, you’ll find you can connect to one share without a password. You’ll then be greeted with the following prompt to show the successful connection: smb: \> 10. What is the token stored in the directory? Now that you’re connected, you can execute commands to interact with the SMB share. If you run ls, you’ll find a token.txt file in the current directory. You can then download the file from the share onto your local machine with: get token.txt On the Kali desktop, open the Home folder and the token.txt will be inside. Open this file and find the token. 11. What is the username stored in the directory? After you’ve run ls in the SMB share, you’ll find not only token.txt, but also a file named creds.txt. Use the same command as you just did previously to download the file onto your machine: get creds.txt This file will also be downloaded to the Home folder, where you can find a username and password. Task: Identify open services on Target 3. Task: Connect to Target 3 with the previously found credentials. 12. What is the token stored in the user's /Documents directory? For this final task, you first need to scan the target using Nmap. You’ll find that if you attempt to scan the target without using the -Pn flag, you’ll get a response saying that the host seems down. However, if you run Nmap with -Pn, you’ll find some ports are open: nmap -Pn <Target 3 IP Address> However, the ports returned from this command don’t offer a way to connect to the target. You’ll also need to scan the 6000 most popular ports: nmap -Pn --top-ports 6000 <Target 3 IP Address> These results will now show two additional ports are open regarding the Web Services Management (Wsman) protocol, which is used to communicate with remote machines and execute commands. One of the tools that implement this protocol is Windows Remote Management (WinRM) which is Microsoft’s implementation of Wsman. Knowing this, you can now use Metasploit to interact with the target. In your terminal, run: msfconsole Once loaded, you can use the the following auxiliary module to connect to a system with WinRm enabled and execute a command with: set cmd ls You’ll then need to set the following options, using the credentials you found in the creds.txt file: set username <username> set password <password> set rhosts <Target 3 IP Address> Next, you need to set the cmd option with the command you want to run. If you use the ls command, you’ll be able to find what out files are in the directory you connect to: set cmd ls With all the options set, you can now run the module: run The results of the executed command will be printed on the screen and also saved to a directory, but both show the existence of a token.txt file in the current directory. You can now set the cmd option to type token.txt in Metasploit: set cmd type token.txt Once set, use the run command to send the updated command: run The contents of token.txt will then be displayed on the screen and outputted to a file. Tools For this challenge, you’ll use a range of tools including: Nslookup Nmap Netcat Sslscan Smbclient Metasploit Tips You can use different tools and parameters within those tools to scan for and find information, so don’t be afraid to try out a few different things!

When you think of a “cozy bear”, you might think of Winnie the Pooh or a faux fur throw by the fire, not a criminal hacker group that’s been active since 2008. There was an intrusion to TeamViewer, the most popular remote access software, on 26 June 2024. Evidence points accountability towards Russia’s Midnight Blizzard group, also known as APT29, the Dukes, and the Cozy Bear group. Not exactly the type of behavior you’d expect from a cozy bear, right? The Cozy Bear group has been observed using tools and techniques that target groups like government, healthcare and energy organizations. Its most common techniques include scanning (T1595.002) and exploitation (T1190) against vulnerable systems. It’s also associated with the notorious SolarWinds incident in 2021 that resulted in the first ever SEC charges against a CISO. It’s safe to say this bear isn’t hibernating, it’s on the prowl. All honey pots aside, Immersive Labs has a dedicated Threat Actor Lab for APT29 and a wealth of content around other attack types perpetuated by this malicious threat group. Ensure your teams aren’t caught in a bear trap by exploring or revisiting content designed specifically around this cyber espionage group: APT29: Threat Hunting with Elasticsearch Successful cyber threat hunting relies on a combination of information from cyber threat intelligence to detailed event logs via endpoints, network devices, and security tools. This lab collection gives you an opportunity to explore some of these concepts through the lens of an emulated APT29 attack scenario. APT29: Threat Hunting with Splunk These labs follow the same attack path as the above collection, but with different tactical and system focuses, providing an opportunity to explore concepts through the lens of an emulated APT29 attack scenario with Splunk. Brute Ratel: Extracting Indicators of Compromise Brute Ratel C4 is a commercial command and control (C2) framework for adversary simulation and red team engagements. This tool has been observed in the wild being used by nation-state actors, specifically APT29. The following labs are also based on this threat group’s known tactics, techniques, and procedures (TTPs) and exploits. Check them out: CVE-2019-19781 (Citrix RCE) – Defensive CVE-2019-19781 (Citrix RCE) – Offensive CVE-2020-5902 (F5 BIG-IP) – Defensive CVE-2020-5902 (F5 BIG-IP) – Offensive We may be having fun here, but your cyber readiness is no joke. Make sure your teams are up to date on the newest CVEs and that they’re well versed on established threat actors and attack vectors – so your organization stays out of the news 🙅♀️🐻📰 Share your thoughts!

While scheduling a Team Sim exercise in the Immersive Labs platform is very straightforward, I’m sharing a list of recommendations and tips for making sure your exercise goes the extra mile: 1. Define exercise objectives Know the purpose of the exercise to keep a laser focus and stop scope creep, which can dilute the exercise experience and learning takeaways. Is this a fun exercise that will encourage engagement, or is it a capability assurance exercise? Knowing your objective is essential for effective planning. For example, a fun exercise might include more guidance and hints than a capability assurance exercise. 2. Block out calendars in advance Identify your participant list as early as possible and send placeholders out to ensure the team’s availability. The more advance notice, the better. At a minimum, provide two weeks’ notice, but ideally one month. In some large-scale cases, whole Team Sim exercise programs are planned and booked out over six months in advance. 3. Host a briefing session These sessions provide a great chance to set the expectations and objectives of the exercise, communicate important exercise information, answer any questions, and, most importantly, get the team excited about it! We recommend organizing a briefing call the week before the exercise. 4. Run a systems test The last thing you’ll want to deal with when your exercise launches is any dreaded technical issues. Make sure you run a systems test early in the planning stages, leaving plenty of time for your organization to make any required configuration changes. You can find system requirement details here. 5. Assign preparation labs Some of the catalog exercises may use security tools unfamiliar to your organization. I believe in the benefits of vendor-agnostic learning when it comes to skills development, but understand that unfamiliar tools can be frustrating. If you have access to our hands-on labs, there are preparation labs available tailored for each catalog exercise. Assign these to participants a minimum of two weeks before the exercise. If you need any help or support with planning, ask a question in our Help and Support forum. Following these steps ensures clear expectations from your participants and a smooth lead-up to your exercise, which plays a big factor in making it a success! Do you have any hints or tips for other exercise planners and facilitators? What lessons have you learned, or where have you seen success?

Let's start with the requirements. In this case, they were clear: 1) To have a fully customised exercise focusing on payment risks and cyber threats like fraud, ransomware, and cash-outs. This is the domain expertise of Mastercard, who had no issues creating this in the Immersive platform with our review and guidance. 2) To deliver this on-site in front of 25 senior execs (including the CEO, CTO, CISO, CFO, and numerous heads of departments). It’s definitely not easy getting this many board members together in one room, so we had to make the first best impression! What did we do, and why was it a success? The stakeholders told us that they’d run tabletop exercises before, so this wasn’t new to them. So, how did we turn what they expected to be a routine drill into an edge-of-the-seat experience? What made our approach unique? Realistic AI-generated videos The amazing Crisis Sim content creation team at Immersive Labs used generative AI to create highly realistic videos that felt as though they were straight from a Pakistani news channel. Mastercard provided us with a few scripts and ideas that helped bring the AI videos to life. AI video of a news reporter tailored to resemble the Pakistani news channel. AI video of a news reporter tailored to resemble the Pakistani news channel. Why did the execs jump out of their seats? That’s because we included the following in the videos: Footage of their building on the news and customer dissatisfaction over cyberattack repercussions. News reporters with local accents and dress styles mentioning the bank and stakeholders, and unhappy Tweets flooding social media. A video of their CEO, not his real face of course, but we used his name when it came to an inject where the stakeholders voted for ‘releasing a press statement to the public’. They even specifically asked us to ensure none of these videos leaked! But each video included the message “Exercise use only – not based on real events”. AI video of the CEO giving a press conference. Collaboration This success was a team effort. Getting any presentation done right, especially in person, requires planning and knowing your audience. This is where Mastercard brought their expertise to create and tailor the Crisis Sim exercise while we supported with our guidance and previous customer experience knowledge. Our roles, tasks, and responsibilities were clear. Top tip: If you’re planning an exercise, collaborate with others for ideas and support. Double act presentation Presenting as a team made all the difference. Mastercard’s expertise in engaging senior execs helped animate the session and avoid awkward silences, while I focused on facilitating the exercise. Doing this alone can be tricky – I’ve personally struggled with awkward silences during solo Crisis Sim sessions while juggling scenario questions, multiple responses, feedback, and facilitation all at once. Sharing the load was crucial, especially in a U-shaped room where I couldn’t easily move around. In this case, I didn’t need to worry about moving away from my laptop, leaving the close-up engagement completely for Mastercard to lead on. Image example of the U-shaped conference room this took place in. The feedback The feedback was overwhelmingly positive – they said it was their first experience with such a tabletop exercise, a stark contrast to their initial expectations. The AI videos sparked significant interest and curiosity. The collaboration between Mastercard and Immersive Labs successfully delivered an educational, engaging, and tailored exercise. The bank expressed interest in running a wider crisis drill in 2025 with multiple banks. So look forward to hearing about that in the future! Finding AI video scenarios in our Crisis Sim Catalogue If you clicked on any of the AI images above thinking it was a video, I’d like to apologise. They were just screenshots as the actual videos included sensitive, bank-specific details like names and locations that we can’t share externally.

The question begs for a prioritisation exercise. You need to create a dynamic program structure to address security priorities and the highest-volume threats, while keeping your finger on the pulse. Let’s dig into how you can balance your priorities Balance role-based learning and skills growth with day-to-day job responsibilities. These learning plans often look like a longer-term goal with continuous growth and skills progression. Some of our favourite Immersive Labs Career Paths (courtesy of the man, the myth, the legend ZacharyAbrams, our Senior Cyber Resilience Advisor are: Network Threat Detection Introduction to Digital Forensics Incident Response and Digital Forensics You can also create your own Career Paths! Buzz your team’s interest and pique security knowledge around the top routinely exploited vulnerabilities and priority threats. Latest CVEs and threats This collection should be a holy grail for referencing and assigning labs on the latest and most significant vulnerabilities, ensuring you can keep yourself and your organisation safe. Incorporate trending and priority threats like #StopRansomware with the below collections: Ransomware In this collection, you’ll learn about the different strains of ransomware and how they operate. Malicious Document Analysis Phishing and malicious documents are major malware attack vectors. Learn to analyse various file types and detect hidden malware. Balance out the flurry of CVEs and news trends with timely and relevant industry content: Financial services customers often prioritise Risk, Compliance, and Data Privacy Collections, or our entire Management, Risk, and Compliance path. We also have a great “Immersive Bank” Mini-Series for a simulated red team engagement against a fictitious financial enterprise. The series walks through the various stages of a simulated targeted attack, starting with information gathering and gaining access, before moving to pivoting and account abuse. Automotive customers might be interested in our CANBus collection to learn more about the CANBus technology in modern cars, and the security threats it faces. We’ve also seen interest in our IoT and Embedded Devices collection and OT/ICS For Incident Responders path! Telecommunications customers may be particularly interested in a more timely lab, such as threat actor Volt Typhoon, which recently made headlines with an attack on ISPs. Due to the group's focus on ISPs, telecom, and US infrastructure, we recommend reviewing its TTPs and mapping them against labs in the Immersive Labs MITRE ATT&CK Dashboard. Other threats may be of higher priority for your sector – reach out to your CSM or Ask a Question in the community to learn suggestions from your peers! Buzz about the latest and most active threat actors and malware because, let's bee real, everyone wants to keep their finger on the pulse of the latest security happenings. Finance, healthcare, defence, government, and national political organisations are on high alert around Iranian-Backed Cyber Activity. The following content on common attack vectors from these groups is valuable to organisations today: IRGC and relevant malware labs: APT35 Peach Sandstorm Tickler Malware Citrix Netscaler CVEs: CVE-2019-19781 (Citrix RCE) – Defensive CVE-2019-19781 (Citrix RCE) – Offensive F5 BIG-IP CVEs: CVE-2022-1388 (F5 BIG-IP) – Defensive CVE-2022-1388 (F5 BIG-IP) – Offensive What would this all look like as part of my program? I like to think of it as a waterfall method, but make sure you consider the overall learning requirement relative to your team’s workloads. Annual: Role-based career paths with a longer duration (doesn’t have to be annual – you can set more frequent targets if that’s better for your team) for completion to meet individual growth and organisation training goals. Quarterly to bi-monthly: ‘Timely training’ with IL Collections or Custom Collections. This might include a mix of “Balance” around industry-relevant content, upskilling to bridge skills gaps, or “Buzzy” content addressing incident retrospective findings that require skills triage, or an industry trend like the rise in Ransomware or Threat Actor risks for your sector, as you reprioritize your internal threat landscape through the year. AdHoc: ‘Threat Sprint’ assignments with new CVE and threat actor labs as a small custom collection with 7-10 day turnarounds per 2-3 hours of content to address quick priority topics. Make sure to get feedback from your teams on capacity. But, don’t bee afraid to iterate as you upskill your teams, stay stinger-sharp against adversaries, and hive a great time delivering on the business outcomes your organisation is looking for.
