During a recent conversation with a friend, the topic of intelligence gathering came up. The idea is to utilize available services such as search engines, underground hacker forums, and IRCs to determine security compromise to the organization. The goal is to utilize intelligence to complement current network security monitoring infrastructure and data leakage prevention. For example, I want to know if my IPs are part of a botnet, have been hacked, backdoored, or being used for other malicious means. Yes, I can scour all the logs and stuff like that, but is it enough?
Quite naturally, the subject moved to using Google (or any search engines) to find if your IP addresses are being used maliciously. A simple example is transparent proxy. The underground community uses proxy to cover their tracks and making investigations harder (but not impossible), while blackhat SEOs (
search engine optimizations) uses proxying for automated links and comments spamming. The list of available proxies are updated very frequently, and the sources on the net are enormous.
So, how do you know if your webserver has been misconfigured or hacked which turned it to become a proxy server? You do a Google search. Having an interest in .gov.my websites, we searched for www.mampu.gov.my's IP address (202.75.4.243) in Google, giving it a simple search query of "202.75.4.243 proxy" (
link). The results are surprising:





Based on Google's search results, it seems that www.mampu.gov.my was listed as a proxy in various forums in July 2009. My guess is the website was probably configured, or hacked. No one knows. A lot more investigations are needed to know how long the proxy was open, and how it was utilized by the underground hackers and blackhat SEOs.
