Google's Binary Search Helps Identify Malware
"A little-known capability in Google's search engine has helped security vendor Websense uncover thousands of malicious Web sites, as well as several legitimate sites that have been hacked, the company said today."
What's really interesting is this portion:
"Hubbard and his team plans to share its Google code with a select group of security researchers, but it will not make the software public, for fear that the tool could be misused by the bad guys."
This is yet another example of the reluctance to share information regarding malware. There's enough information in the article to replicate this information, but there is not enough to make it a viable tool..unless you want to spend a lot of money.
