Has anyone else been seeing the empty-body "PDF" spam, but with a

Thousands of them went through our mail gateways at work. A typo in some

No, merely the next episode in the never-ending spam-wars saga.
A ".fdf" file is yet another Adobe file type and double-clicking on one
(in a Windows box) will launch Acrobat-reader and display its contents.
However anti-spam weapons such as PDFinfo are explicitly coded to look
for ".pdf" files, thus ".fdf" is given a pass.
This shows the cleverness behind (at least some of) the spammers.
A quick edit will update PDFinfo to check ".fdf" files too.
that was done this morning if you want to grab a new version...
