Distorted voices promote stocks using MP3

GFI Software : 18 October, 2007  (Technical Article)
Pump and dump fraud campaigns get new lease of life using disguised voice MP3 recordings to lure victims into buying stocks.
Spammers are back with a new trick, this time round sending messages with MP3 attachments that contain the latest pump-and-dump stock scams.

One sample identified this morning by GFI, was a heavily distorted 30-second MP3 file. A synthetic female voice was used to promote a particular stock. This voice is distorted to avoid filtering approaches based on the file signature.

Once again, spammers are taking advantage of the fact that the MP3 format is one of the most common in use today, another attempt at social engineering.

GFI Software have uploaded a sample on their website for readers to listen to.
