Security Warnings from Xfinity Xfi Network Monitor On MyCloud

My Cloud OS 3 My Cloud Single Bay
1

Hello: I just installed Xfinity (Comcast) network security. I’m getting daily messages that they are blocking access from known hackers trying to get into MyCloud. When I log in remotely, I have to enter my username and password. Is the data in MyCloud protected from hackers? Can they get in without a password? Or are my files exposed to hackers without their knowledge of my password?

Thanks,
Rich Locus

What is the specific error message the XFinity software is indicating? Can you post a screen shot of the error?

Do you have the Remote Access/Cloud Access enabled in the My Cloud Dashboard? If you do not need remote access capability then disable it within the My cloud Dashboard > Settings.

Is the FTP option enabled within the My Cloud Dashboard? If it is not needed, ensure it’s disabled.

Check the Xfinity router settings to see if you are using port forwarding or if UPnP is enabled.

Chances are good that the Xfinity software is just alerting you to inbound attempts that are being blocked by your Xfinity router. Or if the Xfinity software includes a local computer firewall, that it is blocking or notifying you of traffic it thinks is suspect.

Any time one uses the remote capabilities of any computer network device one runs a potential risk of unknown actors gaining access to it via a variety of methods. These methods can include unpatched security vulnerabilities in the device (or computer) itself to one’s WiFi network being compromised through poor password security or even open guest/unsecured networks.

Thanks for getting back to me. I do have the MyCloud password protected. Will that stop the threat since someone is trying to break in. See the error message below from Comcast Xfi.

Here’s What’s Happening

There were attempts made to access WDMyCloud from a known malicious source. We’ve blocked 4 of these threats this week.

Was there ever a solution to this? I’ve started to get the same warning from Xfi. I’ve disabled cloud access to my MyCloud since I’m mainly using it internally but I’d still like to confirm it’s locked down.

I’m having the exact same issue / message. Firmware is up to date.

I’m having the same issue, any news on this?

It’s March 2021 and I’m having the same issues and warnings…the alternatives from xfinity are to make sure the s/w is up to date AND reboot the NAS…
does disabling cloud access resolve the problem?
any other alternative/solution? the alternative is to update s/w and reboot monthly on a routine basis…an annoyance but not a deal breaker…

Having same issue on daily basis. No port forwarding.

I think I may have resolved this issue!!!
After turning off all internet facing services on the MyCloud and restarting my router several times, I was still getting the Xfinity “unauthorized access attempt” warnings from all over the globe.
I scoured the MyCloud settings up and down and realized that there was one service sitting there connecting to the internet, giving my location away to the world.
Here’s what I did:
Go to Settings >> General >> NTP Service, turn it off. Restart your router.
I realize that I’ll have to go in and reset my clock every now and then but, it’s been 8 days since I’ve seen one of those warnings that I was getting every night.
I hope this helps some of you fix those annoying, nerve-racking, messages.

*** Do this in addition to everything that Bennor suggested above ***
