Over at the SANS ISC diary I wrote a diary entry on the analysis of a PDF file that contains a malicious DOC file.
For testing purposes, I created a PDF file that contains a DOC file that drops the EICAR test file.
You can download the PDF file here. It is in a password protected ZIP file. The password is eicardropper, with eicar written in uppercase: EICAR.
