The breach, which has still to be clarified, was discovered on June 19, four day after the initial hack.

In a post, the company said: "An attacker compromised a few of our employees' accounts with our cloud and source code hosting providers.

"Already having our primary access points for code and infrastructure behind strong authentication requiring two-factor authentication (2FA), we learned that SMS-based authentication is not nearly as secure as we would have hoped and the main attack was via SMS intercept. We point this out to encourage everyone here to move to token-based 2FA."

Reddit has reported the cyberattack, which took place between June 14–18, to law enforcement, with Reddit stating that hackers "compromised a few of our employees’ accounts with our cloud and source code hosting providers".

The data accessed by the hackers included usernames, salted hashed passwords (passwords not actually used by users), email addresses and all content including private messages.
