SSAN privacy is a joke, and likely everyone's number is almost public knowledge. SSAN used to be the military serial number and up till a few years before I retired, had to be on my time cards at work. It's only been recent, (15 or 20 years) that now everyone is worried about the number. EFS Open Roads is no different than a bank and you give the bank the number and they are just as likely to get hacked as any other institution.
