More Immersive Cyber Drills: How Rich Media Can Bring a Scenario to Life
When running a cyber drill, it’s useful to have a consistent and cohesive sense of the story throughout. The use of branding and rich media (videos and audio related to the theme) can engage participants through a sense of world-building and storytelling. Imagine your company drill looking like your company — logo, color scheme, font and all. The Brand It’s a good idea to start with all the assets needed to create the custom content. In my case, I created a logo and color scheme for a fictional news company, CHANNEL 6 News. The intention was to create a consistent look and feel for the news updates we would use. Using a simple color palette and classic news branding style, I could then create a virtual website for news updates using presentation software. This allows for ease of editing and can be presented full-screen to look like a webpage. A key requirement of the project was to create content that could be edited by anyone — no special software needed. This is just a slide in a presentation! The slide format could be used to represent a company website, a news outlet, or anything to aid the storytelling. Each slide in the presentation is a copy of the previous, but the news story is changed (title, image, and copy). Rich Media Video is engaging; it grabs our attention and helps with immersion. Video that has relevant branding and specifics has the chance to immerse participants even further. Continuing with the Channel 6 News theme, I used an AI video generator to create a news presenter intro and outro, all within a single prompt to maintain a consistent look. I also created a graphical intro in professional video editing software, aligning the branding and adding stock backing music. Using a more stripped-back video editing app, such as Google Vids, templates can be created with the intro and outro already in place. In between, video clips and voiceover (also generated) provide the main content of the news update. These templates allow for quick editing by anyone without the need for expert software. Download the MP4, and we’re ready to slot it into a cyber drill! Here's an example of the intro/outro and small amount of content between. Company Videos Immersive has a fictional company it uses for Crisis Sims called Orchid Corp. We have brand assets (logos, graphics, etc.) that we use to create print and digital media. I created employee welcome videos using stock media and generated voiceover audio, which ended up being fairly convincing. Now, imagine your company assets in whatever type of video you want. Perhaps a news broadcast, maybe an internal or external press release on the crisis situation. The more entertaining and interesting the content, the more immersion and engagement. Prove and Improve Running drills with custom videos will capture your audience’s attention and imagination. There's a great opportunity to review how the media can be adjusted for further storytelling depth. It could be effective to have the story evolve at a future drill, building on the actions taken previously. Having templates for the content, such as a news update clip, means that significant time is saved in preparation and a consistent feel is kept across drills.
Snort Rules: Ep.9 – Exploit Kits
I am pulling my hair with question number 8 Create a Snort rule to detect the third GET request in the second PCAP file, then submit the token. This one should do it but it is not working. alert tcp any any -> any any (msg:"detect the third GET request"; content:"e31e6edb08bf0ae9fbb32210b24540b6fl"; sid:1000001) I tried so many rules base on the first GET header and still unable to get the token. Any tips?The Human Edge Beyond Pentesting – Building True Cyber Resilience
The Human Edge Beyond Pentesting – Building True Cyber Resilience Pentest vs. Red Team: Understanding the Core Difference Many cybersecurity vendors are rebadging pentesting as attack simulations or red teaming, often at a higher cost. However, there's a clear difference: Pentesting (Penetration Testing): The overarching goal of penetration testing is to find vulnerabilities within an environment in order to create a remediation plan. Reporting focuses on documenting as many vulnerabilities as possible in the allotted timeframe. Red Teaming (Attack Simulation): In contrast, red teaming is used to validate the efficacy of the defensive (blue) team. It is not looking for vulnerabilities per se, it is about achieving the objectives while trying to avoid detection. Reporting focuses on finding defensive gaps and assessing the blue team's response capabilities. The ultimate goal is to simulate real-world adversaries and determine if the defensive team has the telemetry to detect them. The key takeaway is that if the engagement isn't assessing your detection capabilities, it is not a red team. When Does Red Teaming Truly Add Value? While valuable, red teaming isn't always the most cost-effective solution, and really it is usually only effective in these three scenarios: When You Have a Regulatory Requirement: Industries with specific regulations, such as BEST, TIBER, FEER, CORIE, and AASE, often mandate regulatory red teams, which have standardized approaches and qualifications. When You Have a Very Mature Organization: Your organization has addressed all other possible security issues and has limited justification for further spending, a Red Team can provide a level of assurance that few other testing strategies can match. However, if you have known, unaddressed issues, red teaming rapidly loses value as the simulated attackers will typically take the easiest route to compromise and report on issues you are already aware of. When You Need a "Burning Platform": Sometimes, demonstrating the potential severity of a worst-case scenario is necessary to secure critical budget increases. Red teaming can effectively highlight how badly wrong things could go, aiding CISOs in getting the needed resources. However, it's important to note that more cost-effective methods often offer a better return on investment than red teaming outside these specific use cases. Purple teaming offers a more holistic approach to measuring your blue team's capability while also having a much higher knowledge transfer rate. Attack path mapping is far more comprehensive in discovering what attackers can do and what vulnerabilities or misconfigurations can be chained together to achieve compromise. The Pitfalls of Misaligned Red Teaming Several factors can hinder the benefits of red teaming outside the identified use cases: Resource Intensive: Red teaming is both costly and time-consuming. Potentially Divisive: It can sometimes lead to conflict between teams or erode trust within an organization. Weak Follow-Up: Lessons learned from red team exercises are often not translated into actionable steps, or worse completely ignored. Limited Scope: It may fail to explore cascading impacts and real-world disruptions. Insufficient Business Focus: Without an understanding of broader business consequences, the exercise's value can be limited. Increased Risk: Poorly executed red teaming can introduce wasted effort or unnecessary investigations. Often Undetected: A significant number of red team operations do not trigger alerts or go unnoticed by defensive teams. This last point highlights the importance of understanding why an attack wasn't detected, by asking: Was an alert generated? Was it marked as a false positive? Was a process followed? Was the process correct? Enhancing Cyber Resilience: A Holistic Approach Cyber resilience is not just about products or individual tools; it's about the application of skilled and motivated people, understanding and utilizing technology, and implementing reliable and repeatable processes and detections. The focus should be on building a robust, layered defense that understands, anticipates, and mitigates all phases of the attack chain, recognizing that the perimeter is no longer the sole objective for attackers. To truly improve cyber resilience, organizations need to focus on three key areas: Security Posture: Continuously assess and strengthen your foundational security. Detection Capability: Improve your ability to identify and triage malicious activity. Response Capability: Enhance your team's efficiency and effectiveness in reacting to and recovering from incidents. This involves exposing defenders to real-world Tactics, Techniques, and Procedures (TTPs) relevant to their environment. Furthermore, understanding the capabilities and blind spots of both your security team and defensive tooling is crucial for applying and testing effective mitigations and proving resiliency. Practical Approaches to Building Resilience To achieve true benefit from simulations, organizations must prepare individuals and teams before and after the simulation. This involves a cycle of "Prepare & Protect" and "Detect & Respond". Effective training and exercises are vital for different audiences: Individual Preparation: Hands-on labs can provide technical training for various roles, including defensive cybersecurity professionals, penetration testers, developers, application security experts, and cloud & infrastructure security personnel. Technical Team Exercises (Team Sim): These focus on the technical aspects of cyber attack and response using pre-configured cyber range scenarios. Participants investigate or perform simulated attacks using real cybersecurity tools and techniques in a safe environment/sandbox. Executive & Business Exercises (Crisis Sim): Moving beyond traditional tabletop exercises, Crisis Sim puts teams into dynamic crisis simulations with real crises, dynamic storylines, and contextual media. This helps measure and benchmark responses to inform crisis strategies and build muscle memory through regular exercising. By understanding the distinct roles of pentesting and red teaming, strategically applying attack simulations, and investing in comprehensive training across all levels of the organization, businesses can genuinely enhance their cyber resilience and gain the human edge over cyber attacks.Level Up Your Resilience: Analyzing Results and Building a Culture of Continuous Improvement

“We all know the pain of bug reports clogging up a sprint—we thought, what if we could transform that drain on time and morale into a challenge developers are excited to tackle?” Rebecca: Oh, I love that—turning bug backlog dread into bite-sized victories is brilliant. I’m excited to hear more, but first, congratulations on launching Immersive AppSec Range Exercises! This is a BIG deal! No one else does anything like this for developers. Naomi: Thanks! What can I say? My love for cybersecurity goes back to university capture-the-flag events. Pushing yourself outside your comfort zone with hands-on challenges is by far the fastest way to learn. My main goal was to bring that same energy to application security—there are loads of CTFs for pentesters, but not really for developers who need to sharpen their defensive and remediation skills. I also wanted this to be inherently team-friendly. Our individual AppSec labs are built for individual learning, but group dynamics demand different pacing and collaboration tools. Rebecca: Makes total sense. Offensive skills get the headlines, but developers need a solid, team-centric defensive playground too. So how did you translate that vision into the actual structure of our AppSec Range Exercises? Naomi: I anchored everything in the maintenance phase of the software lifecycle: Receive bug → Triage → Fix → Test → Merge. That mirrors real dev workflows, so participants don’t just patch vulnerabilities—they live the ticket management, version control, and testing cadence they’ll face on the job. [Inside scoop: When we build any security exercise, our team maps it to a real-world experience. In Immersive AppSec Range Exercises, a common SDLC workflow—teams learn best when they see exactly how it will play out in their daily sprints. ] Rebecca: I love that you’re training both mindset and muscle memory—jumping through the same process you’d use in production. Once you had that flow, what were the first steps to bring the framework to life? Naomi: Well, I knew that this project was going to need quite a few applications to house the functionality for the exercises, so I audited what we’d need from scratch versus what open source could handle. For ticketing, most OSS Kanban tools were overkill, so I built a lightweight app called Sprinter. Then for version control, we leaned on GitLab—it was quick to stand up and gave a familiar UI for branching and merges. Once those pieces clicked—vulnerabilities surfacing in Sprinter, code pushes in GitLab, and test runs in the Verification view—we had a minimally viable range exercise in action. Rebecca: A smart “build-what-you-must, borrow-where-you-can” approach. Seeing that prototype come together must’ve been so cool. Naomi: Absolutely. It was one thing to design on paper, but watching the pipeline live—tickets flow in Sprinter, GitLab merge requests, automatic test feedback—was a genuine “wow” moment. Rebecca: Speaking of “wow,” let’s talk scenarios. How did you land on “Blossom,” your vulnerable HR app in the Orchid Corp universe? Naomi: Well, we needed something with enough complexity to showcase the framework. HR apps hit three sweet spots: business logic richness, varied user roles, and sensitive data. Tying it into Orchid Corp—our fictional corporation for Immersive Cyber Drills—gave it narrative depth, especially for returning users of our Immersive One platform. Rebecca: And when you designed the actual vulnerabilities inside Blossom, what guided your choices? Naomi: I started with the OWASP API Top 10—that’s our gold standard for spotting the biggest threats. Then I looked at what slips through most scanners and frameworks—nuanced business-logic flaws and edge-case logic bugs—and made those the core of the challenge. To keep things well-rounded, I also added a few classics—things like IDOR, SSRF, and command injection—so every player gets a taste of both modern pitfalls and time-tested exploits. [Inside scoop: Mixing modern, real-world API flaws with a few known “gotchas” keeps Immersive AppSec learners guessing and builds confidence when they spot the unexpected.] Rebecca: I know you’re busy working on the next exercises we’ll release, but before we wrap, how did you test Blossom among developers and engineers? No doubt you wanted to make sure it delivered the right experience! Naomi: Yes, absolutely! We ran a pilot with our own Immersive engineers and a third party, creating a realistic dev team. Watching them collaborate—triaging, patching, merging—validated every piece of the design. Their feedback on pacing and hint levels let us polish the final release. It was one of my favourite days—seeing months of work click into place. After that, we shipped it to customers knowing it was battle-tested. Rebecca: This has been fantastic—thank you for sharing your full planning and development journey, Naomi! From initial vision to a live, collaborative exercise … I’m awed. You certainly put incredible thought and care into developing this revolutionary approach to AppSec training. Final Thought Security is a team sport, and training like Immersive AppSec Range Exercises is the fast track to confident, resilient DevSecOps teams.

My background After two decades in the world of penetration testing and offensive security, I joined Immersive as the Director of Technical Product Management. This new role represented more than just a career shift – it was an opportunity to leverage my deep-rooted experience of cybersecurity to make a tangible difference in how organisations prepare for the cyber threats of today and tomorrow. Throughout my career, I’ve had the joy of working on the front lines of cybersecurity, testing the defenses of organisations of all sizes, from startups to multinational corporations. I worked my way up from a junior consultant in a boutique company to the global head of attack simulation for one of the largest pure-play security consultancy firms in the world. I’ve seen firsthand how attackers operate, exploiting weaknesses not just in technology but in processes and human behavior. I’ve also seen the other side of the coin – what happens behind the scenes when a company identifies a breach and needs to investigate, contain, and recover from it. This journey has given me a unique perspective on the intricacies of cyber incidents – how they unfold, how they escalate, and how they can be mitigated if handled correctly. Over the years, I’ve come to understand that offensive security isn’t just about finding vulnerabilities; it’s about understanding the broader context of how security failures can impact an entire organisation and, most importantly, how to get back to business as usual. One of the key lessons I’ve learned from my time in offensive security is that real-world cyber incidents are rarely straightforward. They’re messy, unpredictable, and often involve a complex web of factors that go beyond the technical realm. In my experience, cyber incidents don’t happen in isolation; they’re the result of a combination of technical vulnerabilities, process failures, and human errors. Attackers don’t follow a script – they’re constantly adapting, finding creative ways to bypass defenses, exploit blind spots, and leverage misconfigurations or overlooked details. This nuanced understanding of how incidents unfold is often missing from the current training and exercising landscape. Realism vs textbook Many cyber resilience exercises available in the market today lack the depth and realism of a real-world attack, and that’s very difficult to capture, especially if you’ve never been exposed to it. Many exercises are built around predictable scenarios, focusing on textbook responses, and just don't capture those swings from tedium to confusion and then to panic. They’re also often performed in isolation, with the investigating/technical team making decisions and performing actions that wouldn’t be in their remit if it was a real incident. One of my all-time favourite incidents showed these to the extreme. It went from a simple ransomware investigation to identifying seven different threat actors in the environment, all with very different TTPs and MOs. You never pick up the other threat actors at the beginning of their attack, usually because they’ve compromised the same machines as the original actor, and you're left wondering why they’ve suddenly changed tactics. Then you get enough evidence to indicate it’s someone else, so now you have two investigations to perform. I’m not saying that all exercising should be done to that level, but I do feel that there’s a nice middle ground that can be achieved. Simulations can highlight things above and beyond simply probing a SIEM for answers to questions about the attack. Putting that into practice At Immersive, I have the privilege of bringing the lessons learned from years of offensive security into the realm of cyber resilience training. My goal over the last 12 months has been to help create more realistic, dynamic, and comprehensive simulations that mirror the true nature of cyber incidents. This means developing scenarios that go beyond the basics – not just testing the technical teams but also involving executives, legal teams, PR, and other stakeholders who play critical roles during a crisis. By integrating real-world attacker tactics, techniques, and procedures (TTPs) into exercises, we can help organisations build muscle memory for responding to incidents in a way that’s both informed and effective. It’s not just creating realistic simulations, it’s highlighting how the results of an investigation can influence the executive team's decision making and how the decisions made by leadership can either help or hinder an active investigation. This is what led to my involvement in building out Immersive Cyber Drills. But what are drills, I hear you ask? Here’s what our marketing team say: “Immersive Cyber Drill events enable simultaneous drilling of executive and technical leadership teams. These facilitated drills use multiple tools from our platform to evaluate an organisation's capacity to detect, respond to, and recover from cyberattacks through a mix of technical and non-technical drilling.” Ultimately, the goal is to empower organisations to respond confidently to the threats they face. Cyber resilience isn’t just about having the right tools or technologies – it’s about understanding the attacker’s mindset, anticipating their moves, and being prepared to act swiftly and decisively when an incident occurs. Building a foundation for Cyber Drills Instead of creating theoretical scenarios or low-risk simulations, we began building exercises that mirrored the attacks I’d seen work in my previous life. The aim was simple: make the drills feel as close to a real attack as possible while keeping the barrier to entry low enough that they’re still achievable to people just starting out. One of the biggest breakthroughs came when we built a standard environment that mimicked much of the corporate world's infrastructure. We then implemented these real-world attacks over the top of those environments and dropped the users in the middle of the attack. This transformed the experience from a disconnected series of technical challenges into a real narrative. Participants were now uncovering the motives behind attacks, following the trail of TTPs left by the attackers, and trying to predict where they went next. Very rarely do security teams get to investigate in a nice, peaceful manner – there are always questions coming from other areas of the business. Leaders aren't just responsible for understanding the attack, they also need to communicate with stakeholders, manage the internal teams, and make high-pressure decisions. As the Cyber Range Exercises (formerly Team Sims) became more realistic, it was clear that the Crisis Simulations used for the leadership team should follow suit. So we built Crisis Sims around the same attack narrative, putting participants in a situation where leadership had to make decisions that they didn’t know the answers to. If they did want to find out, they would need to ask the teams performing the investigation. This forced both teams to think strategically, communicate effectively, and most importantly, anticipate the other team's perspective and restrictions. We also introduced real-world elements like media scrutiny, conflicting priorities, and escalating pressures to mimic the experience of an actual cyber breach. The results were immediate. The teams were forced to think on their feet and develop genuine muscle memory in ways that couldn’t have been achieved through traditional tabletop exercises. And most importantly – they needed to talk to each other. This fusion of leadership training, technical training, and realism has resulted in teams leaving the drill with a stronger understanding of how to work cohesively as a team and how well they communicate across departments. It also provides a better understanding of the types of nuance that can crop up during a cyber breach.
