As antispam tools and e-mail users become more sophisticated, spammers are turning to new mediums to get their unwelcome messages through filters and into inboxes. One of the more recent developments is spam with attached MP3 files. One security software vendor, MXSweep, is reporting that MP3 spam now accounts for between 7 and 10 percent of all spam being sent.
The files are given innocuous-sounding names like elvis.mp3, oursong.mp3, smashingpumpkins.mp3, or coolringtone.mp3. The payload is disappointing: a voice recording touting the virtues of some corporate stock; in other words, it's pump-and-dump stock spam in a new format. It's also a dumb idea. The overlap of those gullible enough to click on MP3 files of unknown provenance and those willing and able to invest in a stock that they've never heard of is certainly minute. It's bound to be more of an annoyance than anything else, and seems unlikely to result in the desired stock purchases.
