New CTI/OT Lab: Norwegian Dam Compromise: Campaign Analysis
We have received reports of a cyber incident that occurred at the Lake Risevatnet Dam, near Svelgen, Norway, in April 2025. A threat actor gained unauthorized access to a web-accessible Human-Machine Interface (HMI) and fully opened a water valve at the facility. This resulted in an excess discharge of 497 liters per second above the mandated minimum water flow. Which persisted for four hours before detection. This attack highlights a dangerous reality: critical OT systems are increasingly exposed to the internet, making them accessible to threat actors. In this case, control over a dam’s valve system was obtained via an insecure web interface, a scenario that could have had even more severe consequences. A recent report by Censys identified over 400 exposed web-based interfaces across U.S. water utilities alone. This dam incident in Norway exemplifies the tangible risks posed by such exposures. In this lab, you will be taken through the attack from an offensive viewpoint, including cracking an HMI and fully opening two valves. Why should our customers care? OT environments, including dams, energy grids, and oil pipelines, are foundational to national security and daily life. These systems cannot be secured using traditional IT playbooks. As OT becomes more connected, tailored security strategies are critical to prevent unauthorized access and catastrophic failures. Who is it for?

KieranNew CTI Labs: CVE-2025-53770 (ToolShell SharePoint RCE): Offensive and Defensive
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? Red teamers Penetration Testers Threat Hunters Here are the links to the labs: Offensive: https://immersivelabs.online/v2/labs/cve-2025-53770-toolshell-sharepoint-rce-offensive Defensive: https://immersivelabs.online/v2/labs/cve-2025-53770-toolshell-sharepoint-rce-defensiveAnnouncing the Immersive Cyber Resilience Awards 2025!

On April 16, 2025, a critical vulnerability, identified as CVE-2025-32433, was disclosed in the Erlang/OTP SSH server. This critical vulnerability allows unauthenticated attackers to execute arbitrary code on affected systems by sending specially crafted SSH messages before authentication. After these messages have been sent, attackers have code execution on the victim machine. This lab will walk you through the mechanics of this vulnerability, helping you understand its implications and learn how an attacker could exploit it. Why is this lab important? Given Erlang's widespread use in telecommunications, IoT, and distributed systems, this vulnerability poses a significant risk to victims in multiple sectors and industries. Customers using Erlang should assess its vulnerability status and patch as soon as practicable. Who is this lab for? This lab is an offensive CTI lab, so it primarily benefits penetration testers and red teamers. That said, it's still incredibly valuable for defensive personas as well, so they can see how the attack could work. These personas include: SOC Analysts Incident Responders Threat Hunters Here is the link to the lab: https://iml.immersivelabs.online/v2/labs/cve-2025-35433-erlang-ssh-offensive
