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.
