The signature is based on a 2240 byte file, so it is probably something embedded in the PDF.

In any case, it needs to be uploaded to <http://www.clamav.net/reports/fp>. Is the MD5 of the entire PDF 013167adb9fbc93923f9c0789599ec95, because Steve and I aren’t finding anything on VT with any detections with that MD5?
