Learning cyber security does not have to mean reading dense technical documentation. The Australian Institute of Cyber Security has developed Cyber Invaders, a browser-based game that challenges players to match real cyber threats with the correct defences, turning one of the most important skills in modern security into an engaging and memorable exercise.
What is Cyber Invaders?
Cyber Invaders is a free, interactive game available directly on the AICS website at cybersecurity.com.au/cyber-invader. No downloads, accounts, or prior cyber security knowledge are required to play. The game presents players with a stream of incoming cyber threats, each falling toward a simulated network. Players must quickly identify the correct defence to stop each threat before it gets through. With only three shields available, every wrong answer brings the network one step closer to being compromised.
What threats and defences does it cover?
The game covers ten of the most significant and commonly encountered cyber threats in the Australian context, including phishing, ransomware, malware, distributed denial of service attacks, SQL injection, credential theft, data interception, insider threats, zero-day exploits, and social engineering. For each threat, players must choose the correct defence from options including multi-factor authentication, staff training, firewalls, data backups, endpoint detection and response tools, software patching, encryption, and access controls. A brief explanatory tip appears after each correct answer, reinforcing the reasoning behind the choice and building genuine understanding rather than just pattern recognition.
Why it works as a learning tool
The game was developed by AICS CEO Simon Smith and draws on the same principles that underpin effective professional training: active recall, immediate feedback, and engagement under mild pressure. Rather than simply reading that phishing is countered by staff training, players must actively retrieve and apply that knowledge while threats are descending toward them. Research consistently shows that retrieval practice of this kind produces stronger and more durable learning outcomes than passive review alone. For busy professionals who cannot always commit time to a full training module, Cyber Invaders offers a focused five-minute exercise that builds and tests practical awareness in a genuinely enjoyable format.
Who should play?
Cyber Invaders is suitable for anyone curious about cyber security, from seasoned IT professionals wanting to sharpen their threat identification skills through to accountants, lawyers, business owners, and managers who carry cyber security responsibilities without a technical background. It is also an effective awareness-building tool that organisations can share with their teams, giving staff a low-stakes way to engage with core security concepts before or alongside more formal training. The game complements the AICS Foundations of Cyber Security course, which builds on exactly the practical knowledge that Cyber Invaders introduces.
