Commenting System Disqus Reports 2012 Hack of 17.5 Million Addresses

Disqus, which builds and provides a web-based comment plugin for news websites, said that hackers stole more than 17.5 million email addresses in a data breach in July 2012. The theft was only discovered now after the database was sent to Troy Hunt, who runs data breach notification service Have I Been Pwned, who then informed Disqus of the breach.
