    I want to stress especially the “novel” use of the onload function of img/script tags. People in the past have used it to detect the presence of different host-names/”port scanning” internal systems by vectoring through a hooked browser. I say that’s cool and all, but you can take that further and use it to detect the presence of a plugin on a target on demand, making you able to be much more sneaky. When the markup detects a plugin present on the target, it redirects the browser to the exploit, and no further requests can be made by that IP to the script.
