Recently we’ve been asked to assist with a few sites that have been hacked. If you use the Gravity Forms plugin to handle your site’s forms (like a contact form) please make sure to update to the most current version. It turns out that there was a vulnerability with older versions of the plugin that gave hackers a way into the site.
To update Gravity Forms (or all of your plugins) click Plugins in the left hand navigation in the site admin area. Plugins in need of an update will be highlighted in orange (unless your version of WordPress is also in need of an update). From there all you need to do is click the Update link.
While you’re at it, it’s probably a good idea to update WordPress too.
