If you are interested in using Twitter for information gathering/mining about potential targets for a penetration test or for “other” research…I highly recommend the very comprehensive article that Lenny Zeltser from SANS put together. Twitter is really becoming a great tool for not just marketing yourself or your business but also to find out detailed information about a company, individual or organization.
One thing I would add to Lenny’s article is that social media in general is the new “hotness” when it comes to information gathering and reconnaissance. If you are a penetration tester you really need to start leveraging all the information contained in social networks! Better yet, use Maltego which can help search multiple social networks and visually show you this data. You can even hit up the Twitter API with local transforms in the new version of Maltego…yummy!
