Polyglot imagesДЄ more sophisticated cousin of steganography, polyglot images donвЂ™t just contain one hidden payload within an infected graphic. Steganographic attacks can hide malware within a tiny cluster of pixels, and in many cases, neither advertising networks nor end users can tell the difference between legitimate and harmful ads until itвЂ™s too late.
