So, this happened. If you Google "191 million voters" you'll find a plethora of other articles. Basically, a whitehat hacker stumbled upon a completely open and unsecured database containing the names, phone numbers, home addresses, and whether or not they voted in different years' primaries and general elections, for all 191 million registered US voters. Thankfully no social security numbers or financial information, but we don't know how long this data was up or who could have done what with it. This database was accessible by anyone who could find the address. There was no security of any kind, not even an encryption.
