Although Doordash is the current leader of the convenient customer service model in the US, the online nature and lack of face-to-face interaction create vulnerability to data breaches and leaks. Per LifeLock, DoorDash customers were the victim of a massive data breach in 2019 that comprised the personal and financial information of 4.9 million customers.

The other Doordash scams include Smishing, which is similar to phishing emails and it is the "practice of stealing personal or financial information through deceptive communications". Since the 2019 data breach, some users reported receiving texts about food orders they never placed and having to click fraudulent links that allowed hackers to collect full financial details.

Culprits also use email phishing where they send emails to users, disguised as DoorDash, prompting them to log in to their account and take a survey with the promise of future discounts, while in fact, harvesting personal information. In the last two years, American and Canadian people saw random changes in the Doordash account, in spite of not using the app.

Customers lost hundreds of dollars on deliveries they didn't order or DashPass memberships they didn't purchase. Caution should also be paid when receiving a DoorDash order as hackers have gained access to data like personal addresses — one homeowner in Ohio called police after a sizable group came to her home for a DoorDash delivery she did not place.
