New PDF Spam Hits Internet
E-mail and Internet content security provider Marshal today warned of the emergence of a new form of spam disguised as an Adobe Picture Document Format (PDF) attachment.
The spam takes on the appearance of a legitimate business e-mail containing an attached PDF file. The PDF features the file name 'username_report.pdf' - the username in the file name is the same as the e-mail recipient's name (taken from their e-mail address). The personalisation of the attachment file name makes it appear more legitimate.
The new spam technique was first used in a recent pump 'n dump spam outbreak that promoted a German company's stock. According to the Marshal TRACE team, we can now expect to see ongoing use of PDF attachments to communicate spam messages.
