"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."

I agree with your comment but you can just drop the word config there. And one would imagine any form of encryption would get past the Goog's "BAD SITE" filters. Though your comment combined with the NSA's invocation immediately post snowden of "big bad steganography" makes me imagine the real issue is using steg in images passed via Goog to communicate. Perhaps because Goog is on some locked down sites whitelist of remote hosts it is allowed to talk to. (just echoing Goog, not meaning to single them out. Replace with whatever other well known site that scrapes and retransmits other sites contents as desired)
