Here's an example of the kind of information that leaks out via Google Calendar's public search feature:
- Go to Google Calendar
- In the search box, type in "moderator passcode"
- Click on Search Public Events
Now, if that search query is expanded for specific terms (use your imagination) and aimed at specific targets (again, use your imagination), the Web-based calendar becomes a gold mine for sensitive data.
I've found information (including e-mail addresses, phone numbers, passcodes and links to supporting documents) in public calendars maintained several well-known corporate entities.
From sales calls to internal department meetings to conference calls with potential clients, the information is all there, available to anyone with an Internet connection.
Google Calendar does offer the user the ability to keep your entries private. You should use it if you value your data.
