After reading the piece on RSnake’s blog at ha.ckers.org I was inspired to try a few other search combinations for Google Calendar. Here is one example of someone who had made public their PGE bill including the account number. This was simply searching on “username” & “password”. I have removed the juicy bits.

PGE Bill Due
Dear Valued Customer,

A new energy statement for your PG&E account 4939******-* is now available to view online. You can also print a copy of your statement online.

PG&E energy statement (e-Bills) information
Amount Due: $86.21
Due Date: April 20, 2007

Then I searched for “Credit Card”. Here is a gent who posted his receipt for tickets to see Rufus Wainwright.

Now, this is not a fault of Google so much as it is a lack of user education. Folks, if you post your calendar event as public then it can be searched.

And my favourite. A Checkpoint staffer posting emails to his Google Calendar.
