MP3 spam – the new kid on the block

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 techies have uploaded a sample on their website, if you want to listen to it, click here.
