New Audio Spam sneaks to inboxes

CGAC (Cellopoint global anti-spam center) detected a latest twist on pump-and-dump spam – audio (mp3) aimed at stirring up the stock. Spammers used the loophole that the current market that all anti-spam engines are unable to know the contents of voice files, they started delivering mp3 email. As users are not wary of audio email, spammers move to use it to entice victims. Such letters are usually no text content with the title is "Cool ringtones", "Wedding Music", and so on. By using social engineering practices, spammers induced the recipient to open it. Users paid less attention to mp3 files. After playing, a voice reads the pump-and-dump pitch. Current spam filtering products are no way yet to identify the content of audio files, and spammers are transforming the voice format and file size into circumvent anti-spam products scanning.
