Food delivery giant DoorDash has confirmed a data breach that exposed customers’ personal information.

In a blog post shared with TechCrunch ahead of its publication at market close, DoorDash said malicious hackers stole credentials from employees of a third-party vendor that were then used to gain access to some of DoorDash’s internal tools.

DoorDash said the attackers accessed names, email addresses, delivery addresses and phone numbers of DoorDash customers. For a “smaller subset” of users, hackers accessed partial payment card information, including card type and the last four digits of the card number.

For DoorDash delivery drivers, or Dashers, hackers accessed data that “primarily included name and phone number or email address.” Users of Wolt, the Helsinki-based online ordering and delivery company acquired by DoorDash last year, are unaffected.

DoorDash says that a “small percentage” of users were affected by the incident but declined to say how many users it currently has or provide an accurate number of affected users.

The company said it cut off the third-party vendor’s access to its systems after discovering “unusual and suspicious” activity.

DoorDash did not name the third-party vendor, which “provides services that require limited access to some internal tools,” according to DoorDash spokesperson Justin Crowley, but confirmed to TechCrunch that the vendor breach is linked to the phishing campaign that compromised SMS and messaging giant Twilio on August 4. Researchers linked these attacks to a wider phishing campaign by the same hacking group, dubbed “0ktapus,” which has stolen close to 10,000 employee credentials from at least 130 organizations, including Twilio, Signal, internet companies and outsourced customer service providers, since March.

DoorDash would not say when it discovered it was compromised, but its spokesperson said that the company took time to “fully investigate what happened, which users were impacted and how they were impacted” before disclosing the data breach.
