Two reports published in the last few months show that malware operators are experimenting with using WAV audio files to hide malicious code.
The technique is known as steganography -- the art of hiding information in plain sight, in another data medium.
In the software field, steganography -- also referred to as stego -- is used to describe the process of hiding files or text in another file, of a different format. For example, hiding plain text inside an image's binary format.
Using steganography has been popular with malware operators for more than a decade. Malware authors don't use steganography to breach or infect systems, but rather as a transfer method. Steganography allows files hiding malicious code to bypass security software that whitelists non-executable file formats (such as multimedia files).
All previous instances where malware used steganography revolved around using image file formats, such as PNG or JEPG.
