The team behind the Joomla open source content management system (CMS) announced a security breach last week.
The incident took place after a member of the Joomla Resources Directory (JRD) team left a full backup of the JRD site (resources.joomla.org) on an Amazon Web Services S3 bucket owned by their own company.
The Joomla team said the backup file was not encrypted and contained details for roughly 2,700 users who registered and created profiles on the JRD website -- a portal where professionals advertise their Joomla site-making skills.
