Public Release of Third-Party Information - "Lead Hunter" Archived

Why did I get an email about a third-party release of information?
The Queen’s IT Services Security team recently became aware of a publication of account details that were released in March 2020. A massive trove of personal information referred to as "Lead Hunter" was exposed on a publicly facing Elasticsearch server. This event may have potentially affected multiple account holders here at Queen’s. As a precaution, Queen’s IT Services will expire the passwords of any Queen’s accounts found to be listed on the site of published accounts and who have not changed their passwords since March 1, 2020.
