Reddit, one of the most popular websites on the planet, announced that a hacker broke into some of its systems and was able to access certain user data, including current email addresses and a 2007 database backup containing salted and hashed passwords.

The hacker compromised staff accounts with Reddit's cloud and source code hosting providers. This occurred despite using two-factor authentication (2FA) to protect accounts from this very sort of thing.
