Following the significant military escalation on February 28, 2026, the global cyber front has shifted into a period of high-intensity risk. While kinetic warfare remains regional, the digital ripples are global, targeting critical infrastructure, healthcare systems, and the very identities of combat and affiliated personnel, and any would-be targets.

Experts warn that Iranian state-sponsored actors are pivoting toward asymmetric warfare, targeting power grids, water utilities, and healthcare systems to project power and cause public disruption. On March 11th, 2026, Stryker Corporation, a US-based multinational medical technology corporation, released an official statement confirming a global network disruption to its Microsoft environment due to a cyber attack. The Iran-linked hacker group Handala claimed responsibility for the attack in a message posted on an X account believed to belong to the group. 

At Immersive, we believe that staying ahead in this rapidly evolving landscape requires technical and non-technical exercises, hands-on skills building, and learning from past experiences.

Let’s dive into how you can use our platform to upskill your teams and ensure your organization is cyber resilient and response-ready.

Know Your Adversary: Iranian State-Sponsored Actors

The lines between government military wings like the IRGC and "independent" hacktivists are increasingly blurred. To protect an organization, you need to know exactly what you’re protecting it from, and Iranian actors are strategically exploiting cyber hygiene gaps to create real-world disruption. Agencies (CISA, FBI, NSA) warn that these actors often exploit targets of opportunity using unpatched software or default

The scenario requires analysts to investigate spearphishing attachments, UAC bypass techniques, extensive system/user discovery via the Windows command shell, and lateral movement executed via PSExec and RDP
  • After-Action Report: Auto-generated performance summary for team members. Includes lab recommendations based on the MITRE ATT&CK techniques, with the lowest accuracy linked to the tasks.

Hardening the Perimeter: MITRE ATT&CK® TTPs

Iranian actors have proven adept at strategically exploiting widespread cyber hygiene gaps to create real-world disruption. You can map our content directly to the retaliatory and asymmetric tactics utilized by these actors.

Initial Access & Identity Defense

Identity is the new firewall. Attackers are currently targeting corporate help desks to reset MFA or passwords - the "help desk vulnerability". National security experts emphasize that identity is the most reliable path to attacker success in 2026.

• T1566 (Phishing): We recommend our Exploitation, Weaponization, and Delivery collection (including Delivery: Phishing – GoPhish), the Staying Safe Online collection, and workforce simulations like Gone Phishing 1-4 or Don't Take the Bait.
• T1110.003 (Password Spraying): Utilize our Credential Access labs, such as Password Spraying and Credential Stuffing, to master the detection of anomalous login activity frequently used by groups like APT33.
• T1078 (Valid Accounts): Learn to track compromised credentials and federated identity abuse through the Active Directory Attacks (e.g., Pass-the-Hash) and Kerberos collections (e.g., Pass-the-Ticket, Stealing Tickets).

Lateral Movement & Persistence

Iranian actors excel at using Command and Scripting Interpreters (T1059) to move undetected through networks.

• Scripting Defense: Upskill your team with our Offensive PowerShell collection (8 labs on execution and AMSI bypass) and the massive PowerShell Deobfuscation series (18+ labs) to detect and bypass these persistent threats.
• T1550.003 (MFA Request Toiling): Try the Password Problems workforce exercise, which simulates a live MFA fatigue attack - a tactic perfected by Iran-aligned groups to bypass traditional MFA during corporate rollouts.

Impact: The Threat of Destruction

The risk of wiper malware (designed to delete data entirely) is at an all-time high. With the heightened risks, practicing recovery is essential.

• Operation Wipeout: A 12-inject Crisis Sim that challenges defenders to respond to a wiper attack crippling core systems.
• Technical Labs: Get hands-on with Hermetic Wiper: Ghidra Analysis, OT Malware: CaddyWiper, and Sandworm Campaign: ZEROLOT Wiper.
• Network Resilience: Address T1498 (Network Denial of Service) via the Distributed Denial of Service (DDoS) Analysis collection, featuring labs on Ping of Death, SYN Flood, and UDP Flood analysis.

High-Priority Risk Areas for 2026

1. Operational Technology (OT) & ICS

Iran possesses some of the most creative operators in the realm of OT and Industrial Control Systems, and May Target Vulnerable US Networks and Entities of Interest. Recent history shows a pattern of compromising Programmable Logic Controllers (PLCs) and Human Machine Interfaces (HMIs) that use factory-default passwords. To protect power grids and water utilities, we recommend your teams review the following training:

• Critical Actor Labs: Explore the tradecraft of actors targeting industrial supply chains in OT Threat Actors: BAUXITE or profile the group notorious for PLC targeting in OT Threat Actors: CyberAv3ngers.
• Malware Analysis: Analyze disruptive malware capable of impacting industrial processes in the OT Malware: IOCONTROL lab.
• Applied OT Cyber Ranges: The Qing and Kween ranges simulate corporate-to-OT network pivots to test defenses of SCADA HMIs.

2. AI Security & Integrity

The rapid rise of AI has introduced a revolutionary yet volatile threat surface. As Dr. Eric Cole recently noted, "poisoning of AI data sets" is a covert tactic used to reduce the effectiveness of military analysis tools; if the data is inaccurate, so too will be the outcome. To address these modern vectors, teams should engage with: 

• OWASP Top 10 for LLMs: A 10-lab collection covering Data and Model Poisoning, Prompt Injection, and Excessive Agency.
• AI Foundations: Gain hands-on experience with the core components of a modern AI implementation including LLM basics, RAG, MCP and agentic AI.
• Deepfake Defense: Our Crisis Sims, such as Boardroom Betrayal, prepare executives for AI-generated vishing and manipulation.

3. Healthcare Sector Resilience

As of March 2026, experts have warned that the U.S. healthcare sector is at heightened risk of wiper malware and DDoS attacks aimed at disrupting daily life. Specialized training is vital for these high-stakes environments:

• Immersive Care Mini Series: A 5-part technical challenge covering SQL injection mitigation and binary analysis in a medical environment.
• Crisis Sim - Healthcare AI: Manage public trust and patient safety when an AI diagnostic tool begins causing misdiagnoses.
• Crisis Sim - Valentine's Day Chaos: A healthcare-specific variant where clinical administrators must navigate operational disruptions alongside critical surges in patient volume.
