25 TopicsEnter 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!74Views2likes4CommentsNew Labs: BlackHat 2025 and DefCon 33
Throughout early August 2025, representatives from Immersive's cyber team attended the BlackHat 2025 and DefCon 33 conferences and got great exposure to the latest technologies, topics, and techniques presented by the sharpest minds in our industry. As a result of attending these talks, workshops, and villages, Immersive has created brand new labs going through the various talks that took place, allowing you to get hands-on with the latest technologies and exploits. We present a number of brand new labs covering some of the most interesting and insightful topics from the events, from operational technology (OT) to achieving privilege escalation through firewall software. AI was a hot topic, as you would imagine, especially around Prompt Injection attacks. We already have plenty of content on Prompt Injection, not to mention the new AI Foundations content, so for this series, we created an Appsec Style lab around preventing Prompt Injection attacks. Why should our customers care? BlackHat and DefCon are two conferences that attract the greatest minds in cyber to get together and share their knowledge through workshops, official talks, and villages. Given the high diversity of events and talks that took place, there is something for everyone! Many of the topic areas shared are things that attackers could easily exploit themselves, so taking advantage of the information in these labs equips our customers with the knowledge of the latest vulnerabilities, threats, and exploitation techniques currently being talked about in the industry - improving your resilience and preparation against the latest threats. Who are the labs for? Offensive Security Engineers and Penetration Testers SOC Analysts and Incident Responders Malware Reverse Engineers Operational Technology Engineers Cyber Security Engineers Here is a list of the labs in this release: Binary Facades: Extracting Embedded Scripts CVE-2024-5921 Redux - Bypassing mitigations to PrivEsc with Palo Alto Global Protect Chrome Alone: Transforming a Browser into a C2 Platform No VPN Needed?: Cryptographic Attacks Against the OPC UA Protocol Python: AI Prompt Injection If you'd like to do any of these labs, here is a link to the BlackHat/DefCon collection: https://immersivelabs.online/series/defcon-black-hat/15Views0likes0CommentsImmersiveOne: Scattered Spider Release

Recently, a critical zero-day vulnerability affecting on-premise SharePoint servers, identified as CVE-2025-53770, was uncovered. This vulnerability allows for authentication bypass, leading to remote code execution, and has been actively exploited in the wild. Eye Security researchers detected an in-the-wild exploit chain on July 18, 2025, during an incident response engagement. This discovery led to Microsoft assigning two CVEs: CVE-2025-53770 and CVE-2025-53771. The attack notably leveraged a combination of vulnerabilities to achieve its objectives, impacting numerous SharePoint servers globally. There is now a public exploit available for anyone wanting to achieve remote code execution. Why should our customers care? This critical vulnerability has been added to the CISA Kev Catalog. and with no authentication or user interaction, a vulnerable SharePoint server can be fully taken over remotely, letting attackers run arbitrary code as if they were privileged admins. SharePoint is a complex and large system that often holds a lot of sensitive data for organizations and is often a targeted system for attackers. Who is the defensive lab for? System Administrators SOC Analysts Incident Responders Threat Hunters Who is the offensive lab for?

Kieran221Views6likes7CommentsBeyond the Badges: Why Women in Cyber Events are a Game-Changer (for Everyone!)
Let’s be honest, traditional cyber conferences can sometimes feel a bit... well, a tad dry, can't they? We've all experienced the endless lectures, the slightly awkward coffee breaks that aren't quite conducive to proper networking, and enough tech deep-dives to make you genuinely pine for your admin tasks! But what if I told you there’s a completely different kind of event out there? One that’s actually, dare I say, genuinely enjoyable? From the moment I stepped in, I was greeted by a room absolutely buzzing with competent and knowledgeable professionals. The shared focus was palpable: to forge new connections and genuinely support one another. This wasn't a room of homogenous backgrounds; it was a vibrant mix of individuals from all walks of life – some cyber-adjacent, some industry newcomers, others in technical leadership roles. Crucially, there wasn't a hint of superiority or self-importance amongst them. It genuinely felt like everyone was eager to engage, to learn about each other, and to passionately discuss the very thing that brought us all together: Cyber! (Yes, we were delightfully a room full of nerds, and proud of it!) We swiftly moved into the main event room, ready to kick off the day's exciting agenda. I must take a moment here to express how incredibly proud I am of Immersive. Utilising our cutting-edge Crisis Sim tooling, we all participated in an extraordinarily engaging simulation, complete with fantastic DC Comic vibes (maintaining that wonderful nerd persona!). What truly set this simulation apart for me was the complete absence of fear when conversations were opened up to the entire room. I genuinely attribute this to the incredibly safe and supportive atmosphere that permeated the entire day. The debates and discussions at each table were simply brilliant, with diverse opinions and experiences beautifully articulated and every single person feeling truly heard. As another example of the brilliance of this event, there was also a moment where one of the guests, using just a lanyard and a pair of scissors, DIY'd a perfectly functioning fridge handle. Inspiring to say the least, though not something that was originally on the agenda. Amongst other fantastic introductions, including a shout-out to WITCH (Women in Tech & Cyber Hub – definitely worth exploring), our very own product powerhouse, Amy Millard, joined the discussion panel. She spoke eloquently about her journey of personal development, overcoming adversity, and masterfully balancing her home and work life. We also had the privilege of hearing from another inspiring Immerser and Woman in Cyber, Emma Walker. Her moving presentation beautifully highlighted the multitude of titles a person can simultaneously hold: Scientist, Psychologist, Wife, Daughter, and Mother to an adorable fur baby. Emma's talk sparked one of the most compelling discussion points of the day: ‘What does resilience truly mean to you?’ Now, if you've managed to navigate your way through this (admittedly lengthy!) post, I'd say that makes you incredibly resilient indeed! For me personally, resilience is about reaching a crossroads, having the courage to choose the most enjoyable option, dedicating yourself fully to that choice, and trusting completely that you've made the right decision. So, to wrap up, I want to share a message with every single professional in this industry, regardless of the gender you identify as: If you ever get the chance to attend a Women in Cyber-style event, DO IT. You might just find it's the most refreshing, insightful, and genuinely fun cyber experience you've ever had.23Views1like0CommentsNew CTI Lab: CVE-2025-32463 (Sudo Chroot Elevation of Privilege): Offensive
On June 30, 2025, the Stratascale Cyber Research Unit (CRU) team identified a critical local privilege escalation vulnerability in sudo, tracked as CVE-2025-32463. This vulnerability, related to sudo's chroot option, can allow an attacker to escalate privileges to root on an affected system. Why should our customers care? This critical vulnerability is reasonably trivial to exploit, and should an attacker gain user-level access to a vulnerable machine, they'll be able to elevate their privileges and have full control over the machine. It has come to our attention that not many people are aware that sudo has versioning. It is a binary that is constantly iterated upon, which naturally may introduce new vulnerabilities. If administrators and security analysts are not aware of how these vulnerabilities work, this can lead to significant risks and impacts. Who is it for?
