In October, dark web researcher Vinny Troia found one such trove sitting exposed and easily accessible on an unsecured server, comprising 4 terabytes of personal information—about 1.2 billion records in all.
While the collection is impressive for its sheer volume, the data doesn’t include sensitive information like passwords, credit card numbers, or Social Security numbers.
