Viva pessoal!

Já alguém tinha reparado nisto?
Até que ponto é que os spammers vão chegar

Na minha caixa de SPAM do Gmail actualmente tenho 670 emails. 129 deles são SPAM com attachments - 29 deles PDF.Research shows that between 65% and 88% of emails received is considered to be spam. Spam continues to be a headache for administrators and end-users because spammers are constantly trying to stay one step ahead of anti-spam software vendors. Although spammers registered considerable success with image spam, the anti-spam software industry had quickly come out with new counter-measures to stop image spam.
As with every cat-and-mouse game, spammers had to respond and in June 2007, they came up with a new technique that is not only ingenious but even more problematic than image spam. Instead of embedding the image within the email itself, they ‘repackaged’ it within an attachment using one of the most common file formats in use today – a PDF file.
