One of my sites (Wordpress) was recently hacked and all the content was deleted. All that was left was a main index page that redirected to the hacker's own site. I was hoping someone here could offer me advice on how to better protect against any future hacking attempts. I've never had anything like this happen before and the site that was hacked is an expired domain hosted on a $1 hosting account while the rest of my sites are with Hostgator. Is security a problem with cheap hosting accounts?
