You mentioned on the eUKHost forums that shared servers are still being monitored? "Security Update: Remote vulnerability in Plesk Panel"
Well I first notified webhostingUK of this issue on Wednesday 04/07/2012 as I had code injected to a website. I was confident it wasn't the password but was advised to change them all and remove the offending code, which I did.
Today, the issue is back - more code has been injected. Via File Manager on Plesk, it was at 12:09 PM - it's 13:50 now. This issue still remains and this site is on 184.108.40.206
Please can you look at this as a matter of urgency?
PS: I've PM'd you the domain name.
