> If you were born before 1989, your SSN can be guessed with 44% accuracy by an algorithm.
The actual situation is quite a bit less dire than your quote.
What that linked article says is that for people born AFTER 1989, the first five digits could be guessed with 44% accuracy. (There's a very real sense that the "last 4 of your social" are less guessable than the first five, so it's no surprise that the last 4 is what is often used/misused.)
I've seen multiple databases that have the results of asking the user to enter the "last 4 of your SSN"
If you have those last 4 digits, and you can guess the first 5 digits with nearly 50% accuracy, then you have a very good chance on getting legitimate SSN's for mass numbers of people with a DB dump.
