Uber says third party breached a database containing information about 50,000 of its drivers

Uber says a database containing the names and drivers' license numbers of 50,000 of its drivers was breached in May.

The ride-sharing service says it has notified the drivers and hasn't received any reports of the information being misused. Uber says it will offer a one-year membership in Experian's ProtectMyID Alert identity theft protection service to the drivers involved.

The company says the breach affects drives in multiple states, but only involves a small percentage of its current and former drivers.

Uber says it discovered a potential breach in September. It announced the events it a statement posted on its blog and described it as a one-time occurrence. The San Francisco company says it has changed the access protocols for its database to prevent similar breaches.
