Recently I have been involved with the analysis of a number of rogue web sites linked to a fast flux network. Tracking websites is hard enough, but the process to analyse the flash code and other scripts has been a head-ache in the past. There are a number of tools that can be used (mostly commercial, though there are some on the OWASP site that are open). The issue being that few of these help to filter the content of the code.
