Can I demonstrate the WannaCry ransomware attack in an isolated lab network?

Yes, ransomware and other viruses can indeed affect files stored on recordable drives like CD-Rs, DVD-Rs, and USB drives. These types of external storage devices are not immune to malware attacks. When these devices are connected to an infected computer or if infected files are transferred onto them, the ransomware or virus can spread to the files stored on these drives as well. It’s essential to take precautions such as using up-to-date antivirus software and being cautious about what devices are connected to your computer to minimize the risk of spreading malware to your external storage devices.
