The video discusses the significant threat ransomware poses to business data, illustrating the rapid and disruptive impact of such attacks. Using the WannaCry ransomware as an example in a simulated Synology NAS environment, the presenter highlights the necessity of robust security measures and reliable backups to prevent data loss and business disruption. The principle of the 3-2-1 backup strategy is emphasized: having three copies of data on two different mediums, with one copy off-site. Tools like Active Backup for Business and Hyper Backup are recommended for creating secure backups and restoring systems.
To contain and recover from ransomware, it is crucial to disconnect infected systems, reset the NAS, and use clean devices along with a live USB of Ubuntu for recovery. This process might involve a lengthy recovery time, and systems should be restored carefully to prevent re-infection. The final segment covers the practicalities of restoring data from cloud backups, stressing the importance of backing up critical files due to space and time constraints. The Synology DS 2422 Plus NAS is highlighted for its suitability for small to medium-sized businesses, providing good storage capacity and network support. Regular, careful backups and vigilance against untrusted files are advised to mitigate the risks from ransomware attacks.

In this part of the video, the presenter discusses the disruptive impact of a ransomware attack on business data, illustrating how easily such an attack can begin from just clicking a link or running an attachment. They highlight the rapid encryption of files and the subsequent demand for ransom, emphasizing the potential for significant business disruption. To demonstrate, they set up a simulated network environment with Synology NAS as a backup. They employ the WannaCry ransomware on this setup to show the breadth of its impact, noting that even though WannaCry is now widely detected, disabling security measures allows it to function as a hypothetical unknown virus. They detail how quickly the ransomware encrypts files and propagates across the network, emphasizing the importance of robust security measures and backups to mitigate such threats.

In this part of the video, the speaker discusses how the ransomware has attacked the Synology network-attached drives, encrypting various files but failing to affect those in a secure “write once read many” folder. The ransomware cannot delete the original files, making them recoverable. The Synology devices run a Linux-based environment, which this ransomware cannot impact, offering a chance to reclaim important files using a clean USB drive. The importance of having a backups is emphasized, recommending the 3-2-1 rule: keep three copies of your data on two different mediums with one off-site. Two tools are highlighted for backup and recovery: Active Backup for Business, which creates secure backup images, and Hyper Backup, which uploads important files to the cloud to avoid data loss from potential onsite corruption. The process for restoring systems from these backups is also briefly mentioned.

In this part of the video, the focus is on steps to contain and recover from a network infection. The infected systems are disconnected to prevent further spread and a clean device is prepared for recovery. A live USB copy of Ubuntu is used, acknowledging it’s not the safest method, but deemed secure with systems offline. The NAS (Network Attached Storage) is reset using the hyper backup C2 Cloud process. They manually set network details to connect and execute a full system restore to eliminate potential threats. Despite an expected quick recovery time, it took two days possibly due to network lockdown. Each user machine is restored via a bootable USB, ensuring no immediate reconnection to avoid re-infection. They manually enter network details, select the required system image, and review partition info before completing the device restore. The process effectively rebuilds their systems and brings the business back online.

In this segment of the video, the presenter discusses the process and considerations of restoring data from a cloud backup, with particular attention to the time involved, which can be several hours for smaller networks and much longer for larger ones. The speaker emphasizes the importance of selecting the most critical files to store in the cloud due to limited space and suggests that for substantial data volumes, frequent cloud uploads may not be practical for small to medium-sized businesses. The discussion shifts to the importance of backing up data to mitigate risks of data loss due to ransomware, which typically relies on social engineering tactics. Practical advice includes not downloading untrusted files and using robust backup solutions for further protection. Additionally, the Synology DS 2422 Plus, a 12-bay NAS provided for the demonstration, is highlighted for its suitability for small to medium businesses, excellent storage capacity, performance, and network support. The segment concludes with details on warranty options and a prompt to visit a link for more information.
