When it comes to data security, prevention is always better than the cure. If you find that your NAS has been attacked by ransomware, what should be done? Unplug or otherwise disconnect from the Internet and delete all files on the NAS except backups. Once there is no evidence of the infection, use Snapshot Center to restore previously backed up files to an uninfected state, making your ASUSTOR NAS your partner in dealing with ransomware with proper backup measures.
