OS reinstall does not work, Hack remains active after doing this from the boot menu.
That's useful to know.

So zeroing the gateway mask to ensure the NAS never connects through the router, backing up the data, and a factory reset/data restore is the way forward. As I mentioned, I'd zero the drives before the reset, just in case a rootkit of some sort was installed.

OS Re-install doesn't wipe the OS partition. It fixes some common problems resetting some settings and overwrites some files, but as root kits can vary it can't go out and get rid of those. Though it's possible depending how they are written an OS re-install may "fix" the problem temporarily, it's likely malware will be designed to re-install itself if it gets broken meaning any fix would be short lived.

BTW, manually setting your gateway IP address to 0.0.0.0 in the NAS might also improve performance - the network being slow indicates that the NAS is attempting to communicate outbound, and it might be succeeding to some degree.


I tried setting the Default gateway for ethernet 1 to 0.0.0.0 and the NAS responds with "Invalid netmask". What are the correct settings that I need to set?

Did this require a complete wipe? Also how, in my case since ive blocked all internet port traffic to my NAS, can tech support access my NAS?

Did not require a complete wipe, Just wiped the OS partition and rebuilt it so it did not wipe data. Tech support can access it if you put it into Tech mode from the boot menu. PM mdgm and I am sure he can help you.

You likely will need to unblock the internet connection on at least one port.

I'm thinking this is what might be causing me massive network issues with my ReadyNAS Pro as well. mdgm, are you able to help me out possibly as well?

OK, my NAS had been hacked...
