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, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the QuestionPro breach exposed and what each item actually enables:
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
Reveals your approximate location and internet provider, which adds credibility to targeted scams.
Also listed in this breach: Browser user agent details, Email addresses, IP addresses, Survey results.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
- IP addresses: No direct action needed, but be wary of anyone quoting your location as “proof” of identity.
- Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.
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.
