Hackers claimed to have stolen more than 2 billion records containing sensitive information including Social Security numbers, with some data reportedly leaked online.
Isn't it the address being leaked with it that makes this notable?
You can't add a number to a SSN and also add a number to the street address to then narrow down which full names are associated with that SSN to then possibly be able to use it.
The address does make it a lot more useful, but the point that I am making is simply that the number itself has never been secure, and this kinda failure was inevitable due to only needing slightly more info than the number itself. A number which itself is already partially identifying.
We shouldn't use social security numbers like we do.
First 3 digits are the area number assigned to a geographic. Next 2 are a group number and are not used serially but have a rather unusual usage sequence. The last 4 are a serial number assigned in order.
