What is ransomware?
Ransomware is malicious software (malware) that encrypts and makes data inaccessible to the victim. The malware contains threats from the attacker to delete, sell or leak the data if payment is not made. Types of ransomware include crypto malware, lockers, scareware, and doxware.
$20 billion
in total global damage is caused by ransomware attacks annually.111 seconds
is the time it takes for another business to be attacked.1304 million
ransomware attacks were reported in 2020, a 62% yearly rise.2Prevent access
Reduce the spread of ransomware by setting file, application, and access permissions, and configure secure login credentials using Secure SignIn and C2 Password.
Protect devices
Outdated systems are at greater risk. Update all your NAS at once with Synology CMS, and safeguard other devices using group policies in Synology Directory Server and C2 Identity.
Avoid suspicious files
Spam and phishing emails containing suspicious files are common methods of spreading ransomware.Synology MailPlus provides strong anti-malware protection and spam prevention.
Check for vulnerabilities
Use Synology Security Advisor to routinely scan for malware, system vulnerabilities, and abnormal login activities. Implement recommended changes to improve your NAS security.
How to recover from a ransomware attack
If a ransomware attack is successful, having backups of your data can reduce the damage caused. Your Synology NAS comes with robust backup features to help you continue operations with minimal disruption. Before restoring backups, it is important to make sure your device has been cleaned.
Back up to your data
Safeguard important files
Avoid getting locked out of your files and folders by setting up real-time versioning or scheduled backups. Your data can retain up to 32 previous versions of files from any computer to keep them safe from folder encryption.
Protect entire systems
Prevent threat actors from holding your deployments to ransom by backing them up to your data. We can easily back up data from physical computers, virtual environments, or SaaS applications.
Synchronize cloud-based data
Keep an updated copy of your public cloud-hosted files. Your data can be encrypted on our server to keep them safe in the event that your public cloud service becomes compromised or inaccessible.
Back up off-site
Add another layer of protection and complete your 3-2-1 backup strategy by keeping copies of your files and restoring them if you are affected by ransomware.
Leverage another site of yours
Defend against ransomware attacks by taking snapshots of shared folders or LUNs and replicating them to another server.
Store data on an external device
Copy your data and configurations to a separate device for safekeeping. Back up your data to remote servers or cloud destinations with powerful customization options to reduce storage usage and protect data against unauthorized access.
Keep a cloud copy
Protect individual objects, entire on-premises devices, and Server data and configurations by retaining unlimited backup copies that are encrypted and stored in a secure cloud infrastructure powered by Cape Pebble.
Restore your backups
Even if your devices have been compromised, you can recover your data and applications by restoring your backups from local backup or an off-site location.
Take back your files and folders
Quickly restore access to LUNs and shared folders on a primary server or fail over to another server. Previous versions of files stored on computers can be restored.
Regain your system
If any of your endpoints are compromised, you can recover PCs, servers, and virtual machines to a previous clean state using backups on your NAS with Active Backup for Business. Your data can also be fully restored from an off-site backup.
Recover with the cloud
Cloud backups are not directly connected to compromised on-premise devices, making them a safe and secure location to retrieve data from. Online backup lets you restore entire PCs or individual files.
