My site was relatively easy to recover and I am lucky that our users were understanding and appreciated our quick response ... but I don't want to have to do it all over again.
Ragnor: Sounds like their shared hosting servers are compromised at a higher level than your individual accounts.
isol: This problem has nothing to do with Wordpress. My site does not use wordpress at all.
I have suffered teh problem for the second time today and while i was repairing the files the attacker was still working and destroying my files again. Of course I have reported the issue again to Servage. I think that the problem is with the FTP and I have changed my password, although I am pretty sure that noone could break my password using brutal force.
itxtme: It would be interesting to know if you are all on the same server? Is it not a possibility the server as a whole has been compromised giving access to everyones accounts on there..
