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.

How urgent is this now?
This data has been circulating for around 4 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.
Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
