Using obsolete applications or templates and plug-ins for them, or using simple passwords is always a risk for your sites as these things make it much easier to hack them. Things can get worse in case you have a few different sites as all of them will be in danger if an attacker gets control of only one of them. This is the reason why we've introduced JailHost - an advanced security feature that isolates Internet sites from each other. In the event that a website is compromised, its attacker will not be able to see or gain access to any other content outside the website folder, so all the rest of the websites part of the account will be protected and will be intact. Using the JailHost option cannot be a substitute for performing routine script updates or using proper passwords, but it'll minimize the damage to your websites significantly, so you'll have to fix only one Internet site and not all of them.
