LinkedIn

LinkedIn suffered a data breach incident in 2016 which exposed the email addresses and passwords of 117 million users.

Hackers broke into the network, stole a database of password hashes, and posted some 6.5 million account credentials on a Russian password forum for the world to see.

LinkedIn’s Chief Information Security Officer Cory Scott took the safety and security of members’ accounts seriously and offered protection tools such as email challenges and dual factor authentication.
