Lead Hunter Data Breach

What happened

In March 2020, a massive trove of personal information referred to as "Lead Hunter" was provided to HIBP after being found left exposed on a publicly facing Elasticsearch server. The data contained 69 million unique email addresses across 110 million rows of data accompanied by additional personal information including names, phone numbers, genders and physical addresses. At the time of publishing, the breach could not be attributed to those responsible for obtaining and exposing it. The data was provided to HIBP by dehashed.com.

Exposed data

Recommended actions

• Watch for targeted phishing emails referencing Lead Hunter — attackers weaponise breach data quickly.
• Stay alert for smishing (SMS phishing) and SIM-swap attempts using your phone number.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
• Check whether your email address appears in this breach on haveibeenpwned.com.
