Zuck has come out with something new, and you always need to watch it when that happens. It's a combination of big data and social networking so that people can easily find new friends, dates, customers or business partners. In short, it's more or less a search engine that allows you to track down facebook users that meet the criteria you specify. With all that personally relevant data at hand, this new Graph Search function is a bonanza for social engineers that now can manipulate you even easier and/or send spear-phishing attacks. This data can be used in a variety of scams. They are currently beta testing and are planning to release it this summer. The only thing I can say is that it is more important than ever to THINK BEFORE YOU CLICK, and get some very good security awareness training.
