The breach occurred on May 4 and affects people who started using the app before April 5, 2018. 

As a result of the breach, an unauthorized third party was able to gain access to users' profile information, including names, email addresses, delivery addresses, order history, and phone numbers.

The last four digits of some consumers' credit cards were also accessed, but not full card numbers or CVVs. For some delivery workers and restaurants, the unauthorized third party accessed the last four digits of bank account numbers. This credit card and banking information is not sufficient to make fraudulent charges or withdrawals, according to DoorDash.

DoorDash recently surpassed Uber Eats to become the second-largest food delivery service in the US after GrubHub, the parent company of Seamless and Eat24, according to Quartz. It is valued between $6 billion and $7 billion.

Months before the data breach was announced, the food delivery app drew controversy over its decision to use tips to subsidize delivery workers' wages, rather than giving tips directly to workers. DoorDash has since announced changes to its tipping policy.

Am I affected by the DoorDash data breach?

DoorDash said it has begun contacting people affected by the data breach and will continue to do so in the coming days.

Anyone who joined DoorDash after April 5, 2018 is not affected and can rule themselves out as a potential victim of the breach.
