Taipei, Taiwan, ngày 26 tháng Một năm 2022 - QNAP® Systems, Inc. (QNAP) today issued a statement in response to a new type of ransomware named DeadBolt. DeadBolt has been widely targeting all NAS exposed to the Internet without any protection and encrypting users’ data for Bitcoin ransom. QNAP urges all QNAP NAS users to follow the security setting instructions below to ensure the security of QNAP NAS and routers, and immediately update QTS to the latest available version.

If your NAS is exposed to the Internet, please follow the instructions below to ensure NAS security:

Step 1: Disable the Port Forwarding function of the router

Go to the management interface of your router, check the Virtual Server, NAT or Port Forwarding settings, and disable the port forwarding setting of NAS management service port (port 8080 and 443 by default).

Step 2: Disable the UPnP function of the QNAP NAS

Go to myQNAPcloud on the QTS menu, click the “Auto Router Configuration”, and unselect "Enable UPnP Port forwarding".
