Plex: Important notice of a potential data breach

#1
Dear Plex User,

We want you to be aware of an incident involving your Plex account information yesterday. While we believe the actual impact of this incident is limited, we want to ensure you have the right information and tools to keep your account secure.

What happened

Yesterday, we discovered suspicious activity on one of our databases. We immediately began an investigation and it does appear that a third-party was able to access a limited subset of data that includes emails, usernames, and encrypted passwords. Even though all account passwords that could have been accessed were hashed and secured in accordance with best practices, out of an abundance of caution we are requiring all Plex accounts to have their password reset. Rest assured that credit card and other payment data are not stored on our servers at all and were not vulnerable in this incident.

What we're doing

We've already addressed the method that this third-party employed to gain access to the system, and we're doing additional reviews to ensure that the security of all of our systems is further hardened to prevent future incursions. While the account passwords were secured in accordance with best practices, we're requiring all Plex users to reset their password.

What you can do

Long story short, we kindly request that you reset your Plex account password immediately. When doing so, there's a checkbox to "Sign out connected devices after password change." This will additionally sign out all of your devices (including any Plex Media Server you own) and require you to sign back in with your new password. This is a headache, but we recommend doing so for increased security. We have created a support article with step-by-step instructions on how to reset your password [here](https://support.plex.tv/articles/account-requires-password-reset/?utm_source=Plex&utm_medium=email&utm_content=reset_password&utm_campaign=sql_db_password_reset).

We'd also like to remind you that no one at Plex will ever reach out to you to ask for a password or credit card number over email. For further account protection, we also recommend enabling [two-factor authentication](https://support.plex.tv/articles/two-factor-authentication/?utm_source=Plex&utm_medium=email&utm_content=reset_password&utm_campaign=sql_db_password_reset) on your Plex account if you haven't already done so.

Lastly, we sincerely apologize to you for any inconvenience this situation may cause. We take pride in our security system and want to assure you that we are doing everything we can to swiftly remedy this incident and prevent future incidents from occurring. We are all too aware that third-parties will continue to attempt to infiltrate IT infrastructures around the world, and rest assured we at Plex will never be complacent in hardening our security and defenses.

This disclosure is no where to be found on their website or blog, and it provides no timeline, no details about the attack, and no details about what data was accessible beyond "a limited subset of data that includes emails, usernames, and encrypted passwords". Very very frustrating.

As of Aug 23 11:24PM PST, Password change page is sort of working, at times displaying error message "Internal Server Error. Something went wrong on our end". I was able to get my request through. Shortly after, a server instance started showing unclaimed status and reassociating it resulted in "Plex is down for maintenance \ Don't worry, it will be back soon \ status.plex.tv".

Forgot my password doesn't work nor the settings screen password change. If you gonna ask all your users to reset passwords you might want to actually scale up to allow them to do that

This. And also if you know what "limited subset" of accounts were compromised, you might want to notify only the users affected, and reset the passwords for them.

Thanks for posting that. I was about to get out of bed to change my password, but now I’ll let it wait until morning.

I personally wish companies would encrypt email addresses in their database, this would at least help against SQL injection attacks and some others (e.g. attacker has only DB system access and not app server access), so it's more difficult for attackers to aggregate data on me. To me it feels very casual waving away the leak of email addresses and just give the usual "passwords were encrypted". But YMMV.
