The Hackers Google
Recently learned about this interesting search engine. It's not your normal search engine instead it surfs the net looking for computer vulnerabilities. http://www.shodanhq.com/ Works very similarly to other search engines you can use quotes and operation characters (+,-) Looks like the results are curated based largely on meta-data, user-agent, and banner results. Moral of the story, don't use default passwords, there is a search for that. http://www.shodanhq.com/search?q=%22admin%22
