Wow, we’ve talked about securing metadata in the past, but this one takes the cake.
Notes from a meeting of the World Motor Sports Council were released recently by the FIA. The document was redacted, as you can see from the example below:

Apparently, the person responsible for redacting the document simply drew a black box around the sensitive text, not realizing that the underlying text was still available. I feel a bit sorry for the poor sod who did this. Simply copy-protecting the PDF would have prevented this type of thing from occurring.
