Hi Sergei0,

There are rumors of a backdoor entry that will provide access to data on WD My cloud drives. This issue did exist however was resolved with a FW upgrade :

This report is based on older firmware 2.30.165. We are already aware of all the issues mentioned in this report.
We released a security update v2.30.172 in Nov (http://confluence.wdmv.wdc.com/x/h9b9AQ) with some emergency vulnerabilities fixed.
The backdoor hack (SKY-10217) is no longer applicable on latest firmware.

We are addressing other security issues in future releases this year.

James.G, thank you for answer, but what you talk about “We released a security update v2.30.172”??? Last Firmware Release for My Cloud EX4 is 2.11.169!
