My Cloud device lockdown

For more information: Support for your My Cloud and WD Cloud device is changing

1. Check which My Cloud device you have: http://web.archive.org/web/20210923084141/http://anionix.ddns.net/WDMyCloud/WDMyCloud_Specs.html

2. See if your device is eligible to update to OS 5: https://www.westerndigital.com/en-ca/support/product-security/wdc-21004-recommended-upgrade-to-mycloud-os-5

   • If yes, update to OS 5 and skip the rest of this document

   • If not, keep reading

3. Block your My Cloud device from the internet

   e.g. for OpenWrt: https://bmaupin.github.io/wiki/other/openwrt/openwrt.html#block-a-client-from-accessing-the-internet

4. (Optional) Use a local NTP server

   1. Set up a local NTP server

      e.g. for OpenWrt: https://bmaupin.github.io/wiki/other/openwrt/openwrt.html#set-up-ntp-server

   2. Configure the My Cloud device to use the local NTP server

      1. Go to Settings, under Language & Clock click _Configure

      2. Click Add User NTP, type in the address of your NTP server (e.g. 192.168.0.1) > Save

   3. Test to make sure NTP is working

      1. SSH to your My Cloud device, e.g.

         ssh -oHostKeyAlgorithms=+ssh-dss root@192.168.0.123
         

      2. Do a manual sync

         # sntp -K /dev/null -S -r 192.168.0.1
         ...
         NTP Server connected successfully!!!
         

5. Start shopping for another NAS :)

   Western Digital provided a coupon to affected owners of My Cloud devices, but I'm not sure I want to go through this again in another 5 years. Synology looks like a good option ... As a plus, Synology devices can sync with Amazon S3 Glacier storage for relatively inexpensive cloud backup.
