OT: pdf spam

[Sattler, Tim]

Hello,

today we received a lot of penny stock spam with just dummy text and a
pdf attachment "<username>_report.pdf". All "spammy" key words are
inside the pdf document, so these mails are not marked as spam in the
majority of cases. If this becomes fashion, I guess it will require new
techniques like regex filtering inside attachments or hash databases for
"spammy" documents.  

Best regards
