LimeLeads: a data breach
In 2019, the now-defunct B2B marketing leads database service LimeLeads suffered a data breach due to an exposed, unsecured Elasticsearch server. The incident exposed tens of millions of records of largely corporate contact data containing 17.8M unique email addresses, along with phone numbers, employers, job titles and geographic locations including state, city and postcode.
