Case at point, spammed messages that have attached MP3 files, which was last seen two years ago, made its presence felt once again today.
Trend Micro researchers were alerted to the discovery of spammed messages that bore no subject and body content. The email message only contained a MP3 file that when executed, a voice advertising Viagra pills and other sexual enhancement pills is heard. The said “voice” also entices users to visit a certain URL, which points to the all-too familiar Canadian pharmacy sites.
In the past, Trend Micro has blogged about how cybercriminals utilized MP3 files or purport as such to proliferate their malicious activities in the following blog posts :

Music Unleashes the Malware Beast
Users are strongly advised not to open and execute attached files from unknowing users. Trend Micro secures users from this attack via its Smart Protection Network that blocks the said spammed messages.
