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, if you want to listen to it, simply click here.
