Old trends never die, they just resurface from time to time. Case in point, spammed messages that have .MP3 file attachments, which were last seen two years ago, made their 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 messages only contained an .MP3 file that when executed, a voice advertising Viagra 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 files that purport as such to proliferate their malicious activities in the following posts:
Users are strongly advised not to open and execute attached files from unknowing users. Trend Micro secures users from this attack via the Smart Protection Network, which blocks the said spammed messages.
