Food delivery service DoorDash this week confirmed a data breach exposing information belonging to 4.9 million consumers, merchants, and delivery workers on its platform.
DoorDash learned of "unusual activity involving a third-party service provider," which it did not specify, earlier this month. An investigation revealed an unauthorized party accessed some DoorDash data on May 4, 2019. While the company says it took "immediate steps" to block further access by the intruder, it's unclear why the breach took nearly five months to notice.
Those who joined the platform on or before April 5, 2018 are affected by the breach; those who joined after April 5, 2018 are not. DoorDash is reaching out to users whose data was exposed.
The type of user data compromised could include profile information such as names, email addresses, delivery addresses, order history, phone numbers, and hashed, salted passwords. Attackers may have also obtained the last four digits of some consumers' payment cards; however, DoorDash emphasizes full payment card numbers and CVVs were not accessed.
For some merchants and delivery workers, or "Dashers," the last four digits of bank account numbers were compromised. Full bank account information was not. Approximately 100,000 Dashers also had their driver's license numbers compromised in the breach.
DoorDash reports it has added security measures around its data, improved security protocols that grant access to its systems, and hired outside security experts for better threat detection.
