Plex warns users to reset passwords after data breach

Zack Whittaker reports:

Streaming media platform Plex has confirmed a data breach and is warning users to change their passwords.

Plex said it discovered the compromise on Tuesday and found the intruder had accessed “a limited subset of data that includes emails, usernames, and encrypted passwords.” Plex vice-president of engineering Schuyler Ullman told TechCrunch that user account passwords are hashed — essentially scrambled in a way that makes them unreadable to humans — using the stronger bcrypt algorithm, and further protected by cryptographic concepts known as salting and peppering, which makes it far more difficult for attackers to unscramble stolen passwords.

A regular reader of DataBreaches kindly forwarded a copy of the email they received yesterday. It reads:

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.
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 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.
