Synology’s Proactive Approach Against WannaCry Attack

Will Synology NAS be attacked?

No. Synology NAS or DSM will not be attacked as WannaCry only targets Microsoft Windows systems. However, if mounted on a Windows mapped network drive with the write permission enabled, the data in the mapped folder might be at risk of being encrypted. We strongly recommend that you update your Windows to be the latest version. You may also find our FAW regarding the ransomware.

How can I protect myself against other ransomware in the future?

Backing up your files regularly and frequently, as well as performing regular operating system and software updates, are the best practices (WannaCry uses the EternalBlue Exploit to spread through a local network which doesn’t have the recent security updates installed). Remote and multi-version backups can increase files accessibility in case of a disaster. In the addition, mapping ans sharing only the necessary shared folder on your NAS can also minimize the impact of an attack.

Strategy 1

Back up your PC’s files to Synology NAS

Synology Cloud Stattion Backup can back up the data stored on your PC to Synology NAS servers. You can retain up to 32 historical versions of single file, allowing you to restore files to a previous state, ans restore your folder to a point in time when needed. Learn more

Strategy 2

Back up NAS data to other destinations

Backing up locally just might not be enough should a ransomware attack the shared folders on your NAS server through accessing file services on your PC. The best way to prevent this is to add another layer of protection by having uninfected backup versions stored at an offsite location. If you fall victim of ransomware, you can still access data stored at different locations. Synology provides you with two backup packages:

Hyper Backup

Hyper Backup lets you enjoy a full range of multi-version backup destinations from local shared folders, and external hard drives, to network shared folders, rsync server, and public cloud services. No matter which destination you choose, you can restore your data to a previous unaffected version in case of disaster. Learn more

Snapshot Replication

Snapshot Replication on select NAS models allows you to replicate data from a promary site to an offsite location up to every 5 minutes for shared folders and 15 minutes for LUNs, ensuring all your critical data in shared folders or virtual machines in iSCSI LUNs can be recovered quickly in the event of disaster.

Steps to take when discovering ransomware infection 

In the unfortunate event that you have encountered a ransomware attack, do not fret. Turn off your WiFi or unplug your network cable—make sure you disconnect yourself from the internet immediately. The next step is to have your computer system completely wiped clean of infection. Make sure your computer is at a clean state before restoring previous versions of files that were backed up via Synology backup features.
