Researchers analyzed web traffic gathered through the university’s Security Behavior 1xbet Observatory (SBO), a group where users can sign up to share their browser history to help with academic inquiries. Data on 249 participants was collected between January 2017 and December 2018. 

Of the users, 63 had accounts on breached domains that publicly shared a breach during the collection period. Of those 63 users, 21 went to the breached sites to change their password. Further, just 15 of those users did so within three months of the announcement.
