MTA Website 'Feature' Lets You Track Subway Riders' Locations
Slash_Account_Dot shares a report from 404 Media, written by cybersecurity journalist Joseph Cox: In the mid-afternoon one Saturday earlier this month, the target got on the New York subway. I knew what station they entered the subway at and at what specific time. They then entered another station a few hours later. If I had kept monitoring this person, I would have figured out the subway station they often start a journey at, which is near where they live. I would also know what specific time this person may go to the subway each day. During all this monitoring, I wasn't anywhere near the rider. I didn't even need to see them with my own eyes. Instead, I was sitting inside an apartment, following their movements through a feature on a Metropolitan Transportation Authority (MTA) website, which runs the New York City subway system. With their consent, I had entered the rider's credit card information -- data that is often easy to buy from criminal marketplaces, or which might be trivial for an abusive partner to obtain -- and punched that into the MTA site for OMNY, the subway's contactless payments system. After a few seconds, the site churned out the rider's travel history for the past 7 days, no other verification required. On the OMNY website, the MTA offers the ability for riders to "Check trip history." This feature works for people who use contactless bank cards when entering the subway, or other solutions like Apple Pay and Google Pay. The issue is that the feature requires no other authentication -- no account linked to an email, for example -- meaning that anyone with a target's details can enter it and snoop on their movements. The MTA does offer the option of an OMNY account, which requires a password. The website says having an account lets riders "Securely access your trip history." But the first option that appears on the trip history website is the unauthenticated version. After 404 Media raised the concerns to the MTA, a spokesperson said the agency will look into improving the system. "But at the moment, the tracking feature is still accessible without any authentication," notes Cox.
