For the purposes of fraud, it's fairly easy to link accounts across datasets even without a unique key like SSN. You can just guess based on name and address or something and if you're only right 90% of the time that's still a pretty big win.
- cm2187 9y agoPeople move home, particularly in the US which has a quite mobile population. Many people have many variants of their names, including middle names or long composed last names, and you have a huge number of homonyms. So while you may get a 90% hit rate on two, perfectly current, and breached at the same time datasets, I would expect that number to reduce greatly in a typical real world breach.
