On February 14th, the U.S. Senate published the Cyber Security Act 2012 (.pdf), and somewhat ironically, forgot to strip metadata. That is, it seems that whoever published it was not aware of NSA's 2008 (!) publication Hidden Data and Metadata in Adobe PDF Files: Publication Risks and Countermeasures (.pdf): the Cyber Security Act 2012 pdf file contains metadata that reveals, unless the information is intentionally deceptive, that it was produced by user hen using Acrobat Distiller 10.1.2 (Windows) and ACOMP.exe WinVer 2.0 Nov 24 2008. I consider it most likely that the pdf was indeed produced at the U.S. government, not at some external party. A fortiori, the pdf contains too much information. Simply, too much information. (For the obvious reason that it has misuse value for targeted attacks.)
