The latest Java exploit has given another view into the workings of the cybercrime economy. Although I should not be, I am always startled at just how open and robustly capitalistic the whole enterprise has become. The business is conducted more or less in the open.
Krebs on Security has a nice piece on an auction selling source code to the Java exploit. You can see that there is a high level of service provided, and some warnings about now to ensure that the exploit you paid for stays valuable.
