Investigation notes

An official data breach filing from QuestionPro Inc has confirmed a security incident that occurred on August 12, 2026. As a major enterprise software and market research firm, QuestionPro Inc processes extensive consumer and corporate data, making the security of its systems critical. The precise nature of the breach remains unspecified in the initial filing, which is currently under review by investigators.

The company has reported that the exposed information includes individuals' Full Name, Email Address, Password or Credential Hash, Mailing Address, Telephone Number, Date of Birth, Purchase and Order History, and Demographic and Survey Response Data. This combination of personal identifiers and detailed profile information creates heightened risks for those affected, potentially leading to targeted phishing scams, credential stuffing, and other forms of identity theft.

While the filing confirms the incident and the categories of data involved, many critical details are still under investigation. It is not yet clear how unauthorized access was gained, how long the attackers maintained access to QuestionPro Inc's systems, or the total number of individuals impacted. These factors are crucial in understanding the full scope of the company's security failures and the potential harm to affected parties.

Companies like QuestionPro Inc are legally obligated to implement robust security measures to protect the sensitive data they collect and manage.
