DropBox was actually hacked in mid 2012

So if you have not changed your DropBox password since mid 2012 GO DO THAT NOW!  This is news here in 4 years later in August of 2016 because the data has recently become available and with so many people not changing their passwords combined with using the same passwords across multiple sites means this breach will lead to more security breaches.  If you are one of those people I highly recommend you consider using a password management tool such as https://lastpass.com/   If you would like to learn more about LastPass I have a review you can watch here.
