Owners believe DeadBolt obtained access using Asustor's EZ Connect software, which enables customers to connect to their NAS systems from anywhere in the globe.

If you're running an Asustor device, you'll want to disable the EZ Connect utility suspected of being vulnerable to the exploit and physically disconnect your NAS from the internet.

The DeadBolt ransomware is now targeting ASUSTOR NAS devices by encrypting files and demanding a $1,150 ransom in bitcoins.

Asustor advises disabling EZ Connect — which lets users access device data remotely — then performing a full backup, as well as switching off Secure File Transfer Protocol (SFTP) services.

Following ransomware attacks against QNAP NAS devices, it is now Asustor’s turn to suffer, according to multiple reports of Asustor NAS devices being attacked by the DeadBolt ransomware.
