QuestionPro data breach

Breach date: 2022-05-21. Added to this index: 2022-08-05. Accounts affected: about 22M. Domain: questionpro.com.

What happened

In May 2022, the survey website QuestionPro was the target of an extortion attempt relating to an alleged data breach. Over 100GB of data containing 22M unique email addresses (some of which appear to be generated by the platform), are alleged to have been extracted from the service along with IP addresses, browser user agents and results relating to surveys. QuestionPro would not confirm whether a breach had occurred (although they did confirm they were the target of an extortion attempt), so the data was initially flagged as "unverified". Subsequent verification by impacted HIBP subscribers later led to the removal of the unverified flag.

What was exposed

  • Browser user agent details: A short text string your browser sends to every website, naming the browser, its version, the operating system and often the device type, for example Chrome on Windows or Safari on an iPhone.
  • Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
  • IP addresses: The network addresses your devices used when you signed up, logged in or posted, recorded by almost every website in its access logs.
  • Survey results: Your answers to market research, customer feedback, political polls, health questionnaires, workplace surveys or quizzes, sometimes linked to your name or email address.
