Is Stegomalware in Google Play a Real Threat?

For several decades, the science of steganography has been used to hide malicious code (useful in intrusions) or to create covert channels (useful in information leakage). Nowadays, steganography can be applied to almost any logical/physical medium (format files, images, audio, video, text, protocols, programming languages, file systems, BIOS, etc.). If the steganographic algorithms are well designed, the hidden information is really difficult to detect. Detecting hidden information, malicious or not, is so complex that the study of steganalytic algorithms (detection) has been growing. You can see the growth in scientific…
