Security researcher Jeremiah Fowler together with the Website Planet research team discovered a non-password protected database that contained 822,789 records. The dataset had detailed information on trucking, transport companies, and individual drivers. The data appeared to be connected to credit accounts, loans, repayment, and debt collections. This included banking information and tax ID numbers. Many of the Tax IDs were consistent with what appeared to be SSN (Social Security Numbers) and stored in plain text.
