Google Users have had their Calendars Shared With the World.
Thousands of Google
users are exposing the contents of their calendars to the public. The
information is indexed by search engines and can include email addresses
as well as private events from individuals
and businesses. The problem is due to misconfiguring Google Calendar to
share its contents with others. However, making the data public means
that anyone with your Calendar link can access it. Google shows a
warning about this but thousands of users seem to
ignore it, allowing their calendars to be available in public searches.
Even organizations appear to disregard the notification, ending up
disclosing business-related information to the world.
