A booby-trapped e-mail that promises free sex movies is racking up victims around the world, warn security firms. Some variants of the Windows worm contain a link to PDF that a recipient has been told to expect. Those clicking on the link get neither movies nor documents but give the malware access to their entire Outlook address book. When installed, the worm sends copies of itself to every e-mail address it can find.
The malicious e-mail messages have a subject line saying "Here you have" and contain a weblink that looks like it connects to a PDF document. Instead it actually links to a website hosting the malware.
