Boeing, American Airlines Pilot Association, Healthcare giant Henry Schein, Marina Bay Sands, Samsung, a U.S. Nuclear Research Lab, Japan Aerospace Space Agency and mortgage giant, Mr. Cooper. What do all of these organisations have in common?
They recently became victims of cyber crime. Some had their data encrypted, stolen or leaked. In many cases operations were disrupted for days and many will face regulatory and compliance challenges in the days to come. Our monthly list of the biggest cyber attacks, ransomware attacks and data breaches captures all the major cybersecurity incidents that took place in the month of November, 2023.
The objective as always, isn't to turn the spotlight on the victims, but to emphasise the rise in cyber crime and how it can impact almost every business or government body. The only real prevention today is preparation. Nobody can save you from cyber attacks but you can save yourself by mitigating their impact through effective cyber incident response.
Also, make sure you test your response capabilities through regular cyber attack tabletop exercises. These act like a litmus test of your cyber resilience capabilities. While we always recommend hiring an external facilitator for your cybersecurity tabletop exercises, if you plan to run your own, don't forget to use our free resources and customise them to your organisational needs and threat context.

- Cyber Security Tabletop Exercise Template
- Cyber Tabletop Exercise PPT
- Cyber Crisis Tabletop Exercise Checklist
These resources have been created by the world's #1 tabletop exercise facilitator and can help you run and effective incident response tabletop exercise of your own.
