We have been seeing an uptick in SPAM containing PDF attachments. The PDFs are composed of a full-page image that, when moused-over, points to a malicious web site. We have tried to use Transport Rules to block these based on the moused-over URL but Exchange seems unable to properly detect these embedded URLs. We are able to use Transport Rules to block PDFs with plain text so we know that the server is inspecting them properly.
Any ideas on how to battle these pesky messages? ________________________________ CONFIDENTIALITY NOTICE: This email contains information from the sender that may be CONFIDENTIAL, LEGALLY PRIVILEGED, PROPRIETARY or otherwise protected from disclosure.
