Recently, we have received reports of some TNAS devices being attacked by Deadbolt Ransomware. Based on the case analysis, we preliminarily concluded that this was an external attack against TNAS devices. To protect your data from Deadbolt, please take action immediately!
If your NAS works normally, we suggest the following countermeasures:
1. Upgrade your TOS to the latest version;
2. Install good anti-virus software on your computer, TNAS device and router to help you detect and resist malicious threats;
3. Disable port forwarding on your router. After disabling this function, you will not be able to access TNAS through the TNAS device bound to the DDNS external network;
4. Disable the UPnP function on your TNAS. After disabling, your PC, multimedia box, TV and other devices may not be able to access TNAS through UPnP protocol, please use DLNA, NFS, SMB protocol to access TNAS instead.
If your NAS has unfortunately been affected by Deadbolt, please do as below:
1. Remove the LAN network cable from your TNAS device immediately;
2. Power off your TNAS; x.86 models: short press the power button; ARM models:long-press the power button 3 seconds;
3. Do not initialize your NAS as this will erase your data;
4. Please contact the online support on our official website or email to support@terra-master.com directly.
