SAN JOSE, California — Spam is now being served in audio form. The latest in unwanted electronic communication is an MP3 file that began landing in inboxes around the world last week. It features a spooky, synthesized Darth-Vader-sounding female voice touting the stock of Exit Only Inc., traded on the lower-standard Pink Sheets.
“Hello, this is an investor alert!” the halting, at times unintelligible voice says. Her pitch invokes the growth prospects of Exit Only, a Web site operator that runs Text4Cars.com, which links auto buyers and sellers via text messages. Computer security researchers say the audio blasts — MP3 files with misleading names attached to spam e-mails — reflect spammers’ need to slip their messages through increasingly sophisticated e-mail filters.
