The second common was PDF (Adobe Acrobat Reader) 28.61% share. This year, F-Secure have discovered 663 targeted attack files and the most common file type has been PDF with 48.87% of the files. DOC is now second common with 39.22% share.

According to F-Secure explanation for this is mainly cos Adobe Acrobat & Reader have had more vulnerabilities than Microsoft Office applications. Two vulnerabilities are still waiting for patching. Adobe expects to have resolving updates ready by May 12th, 2009.
