Analytical Summary of the BlackHole Exploit Kit

Almost Everything You Ever Wanted To Know About The BlackHole Exploit Kit

There are hundreds, if not thousands, of news articles and blog posts about the BlackHole Exploit Kit. Usually, each story covers only a very narrow part of the subject matter. This talk will summarize the history of the BlackHole Exploit Kit into one easy to follow story. There will be diagrams and flow-charts for explaining code, rather than a giant blob of illegible Javascript, PHP, or x86 Assembly.

A. What a browser exploit kit is, and what it isn't

  1. It only does exploits
  2. Directing victims to the exploits is out of scope
  3. Usually done with spam or iframe injections
  4. The actual malware installed is out of scope too
  5. Where is exploit kit is hosted, is also quite variable
