It seems that spam in the form of PDF attachments has increased significanlty in the last month. I’ve certainly noticed it and opened it just that one time before realizing what it was and praying that I hadn’t released something nasty. There’s something about a PDF that we trust. PDF’s have the association of being a locked file that can’t be edited and that generally won’t contain viruses. They however harbor links to web pages that are riddled with all type of nasty things.

Spam filters are also having a hard time with it. Microsoft files like Word Documents or Powerpoint Presentations are the usual suspects when it comes to infected attachments, so the PDF’s are bypassing the filters and landing in your inbox.

Is there a solution - of course - but it’s just common sense

“…organizations need a layered defense to better arm themselves against such threats — with security software deployed at the gateway, at the client and at the server.”
