"Zeus is a trojan designed to steal banking credentials, and has been declared one of the most successful pieces of malware currently seen in the wild. A new variant is making detection far more difficult for anti-virus companies by hiding configuration settings inside pictures. At the moment, the malware simply encodes the configuration with Base64, passes them through XOR and RC4, then attaches them to the end of an image file. This makes for an 'infected' file that is much larger than the original. There is speculation that future releases of the malware will be able to detect minuscule changes to the colors of individual pixels, making the affected files much harder to detect."

    Sorry; not Steganography. It's late. That's my excuse and I'm sticking to it.

    You could have gotten away with it, everyone who replied so far has gone along with "stenography".
