I disagree with the description of this using a technique called Steganography, which is the art of hiding something inside something else, such as an encrypted file in a JPEG image. Steganography is used to transport information secretly. This is just plain buffer overruns in internal browser or os code. They aren’t “hiding” the exploit in the graphic, they are using corrupt graphic data to exploit a software bug.
I doubt it actually displays a graphic image, such that people who aren’t infected don’t notice a problem. If it does, then I guess this description would be correct. But steganography usually betrays itself in the size of the container, because they are usually much larger than a “normal” container.
If you ask me, this kind of blanket attack is very likely to succeed in a large number of cases. Way too many people think they are not rich and interesting enough for crackers to steal their money, but they’re wrong.
This is why my firewall protects my router from internal threats, in addition to external threats. You never know when you’ll be tricked into clicking something malicious. It’s fascinating how many devices do try to connect to the router.
