fdf spam

Has anyone else been seeing the empty-body "PDF" spam, but with a .fdf file
extension.  Had a whole pile in my inbox here this morning.  

Cheers,

Here are 2 rules for detecting pdf spams.

full NULLTXTPDF /(\n(?:-{12,}0\d{22,}|--={19,}_\d{6,}==_)\n)Content-Type: text\/plain; charset=\"{0,1}[\w-]{5,}\"{0,1}; format=flowed(?:\nContent-Transfer-Encoding: 7bit){0,1}\n{2,}\1Content-Type: application\/(?:pdf|octet-stream);(?:\n| name=\")/

full HTMLPDF /(-{6}=_NextPart_000_00[0-9A-F]{2}_[0-9A-F]{8}\.[0-9A-F]{8})\nContent-Type: multipart\/alternative;\n.boundary=\"(----=_NextPart_001_00[0-9A-F]{2}_[0-9A-F]{8}\.[0-9A-F]{8})\"\n\n\n--\2\nContent-Type: text\/plain;\n.charset=\"{0,1}[\w-]{5,}\"{0,1}\nContent-Transfer-Encoding: quoted-printable\n\n\n--\2\nContent-Type: text\/html;\n.charset=\"{0,1}[\w-]{5,}\"{0,1}\nContent-Transfer-Encoding: quoted-printable\n\n(?:.+\n){5}<STYLE><\/STYLE>\n.+\n.+\n<DIV><FONT face=3DArial size=3D2><\/FONT>&nbsp;<\/DIV><\/BODY><\/HTML>\n\n--\2--\n\n\1\nContent-Type: application\/(?:pdf|octet-stream);/

I think what he is asking, and I sure am, is how do you get sa-update to pick 
up these new modules.  I have PDFInfo.pm installed, but an sa-update -D

session ignores that fact.  A config error someplace?  Smart did update some

beginning to drown in this crap.

So how DO we get sa-update to actually update this stuff?

Thanks.

Could somebody PLEASE make sure that when a new version of PDFInfo is posted
the website shows the updated version number? The page still says it's
version 0.7 last modified 2007-07-27, and you have to actually read the .pm
to see that it's now at 0.8.

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.

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