Samsara Marketplace has got drugs, counterfeit money, credit cards, paypal accounts, voter records, and all sorts of other stuff for sale. If you need a hundred children's social security numbers to report illegal immigrant employee income with, Samsara is a place to get it from.
Where do sellers steal something like lucrative medical records from though? Well, sheeit son, that's easy, because hospitals and doctor's offices have all gone crazy for computers! Paper records in hospital basements that are impossible to steal remotely are all entered into electronic databases now - free for the undetected taking!
So, next time you're sitting alone in a doctor's office exam room waiting for someone to walk in and stick something in your mouth or up your ass, why not stick a wifi keylogger into the back of that PC and come back a week later and siphon all that shit out without even having to enter the building? Of course there are a million other ways like phishing and PHP and SQL attacks to get lucrative medical and insurance records, but I'm posting this one because I can put one thing that drives me up a wall about the totally nonexistent security of every fucking doctor's office I walk into nowadays into one simple picture. They'd never find it. They wouldn't know what it was and would probably leave it in place if they did. They don't even know what you're talking about if you try to explain the problem with allowing thousands of people off the street unrestricted and unsupervised physical access to their computers and internal networks.
