I have noticed over the last month or so that most of the spam I get seems to contain simply a PDF attachment. I was wondering whether this was a new tactic designed to fool people into opening up a dodgy file. I came across this article today that claim spammers have stopped sending pictures in their emails and instead started attaching PDF’s. It appears that they are doing this to try and get around corporate spam filters. So far, it appears to be getting through my spam filter quite effectively with several hundred of these spam mails with PDF attachments arriving each day. Whilst my daily amount of spam mails continues to rise, I suppose one good thing about this latest trend is I don’t have to read about Viagra or penis enlargement unless I actually open the PDF.
