Hacked by team mosta
I have Powerstore 3 running on a site on our server on this URL: www.wildcareshop.com/
The site functions fine BUT recently some images have gone missing and when I checked the folder where cms files are uploaded I found several text files that I had not uploaded. The content of the text file was simply the phrase 'hacked by team mosta' and an email address.
Is this a big security problem, is it something to do with Powerstore or a more general security issue on our server.?
