It seems impossible to think that the answer is HealthCare.gov is just too secure for hackers to break in. After all, no one can write "500 million lines" of code (assuming that figure is correct) without making a few mistakes. There's just no way that software vulnerabilities, which hackers can use to break in, aren't part of the mix.
As a marketing professional, there is nothing I hate more than receiving any form of communication (email, Web experience, social media, mobile, whatever) and not see an obvious place where I can either opt out of the communication or protect how much information is being captured. As a consumer, I probably hate it more.
Anonymous sub-group Anti-Sec supposedly holds in its hands 12-million Apple user IDs it acquired from hacking. The hacktivist group refuses to release the IDs until -- wait for it -- Adrien Chen of Gawker poses on the front page of the site in a ballet tutu with a shoe on top of his head. It remains to be seen whether Anonymous does have anything to give the public it strives to supposedly protect, or whether this was just another one of their pranks done "for the lulz," that is to say, for the stroking of their own vanity.
Whether con games are played in the digital world or the physical one, getting someone to lower their guard with a clever ruse makes the life of a thief that much easier. In the vernacular of hackers, this is called social engineering. Social engineering is about hacking the human mind, something that in many ways is significantly easier than finding a new software vulnerability and using it as a gateway into your enterprise. One way to get hold of that information is to target people according to their jobs and interests, and there is perhaps no greater source of data on those subjects than social networks.
