Plex confirmed a security breach where an unauthorized party accessed one of its databases, exposing a subset of customer data. The compromised information included **email addresses, usernames, and securely hashed passwords**, though Plex emphasized that passwords were hashed per industry standards (algorithm undisclosed). While payment card data was not at risk—since Plex does not store such details—the incident marks the company’s **second major breach in recent years**, following a similar 2022 attack. Plex contained the breach swiftly and mandated password resets for all users, advising additional precautions like enabling **two-factor authentication (2FA)** and logging out of active sessions. The company fixed the exploited vulnerability but did not disclose technical specifics or remediation steps. The exposure of **customer credentials** raises risks of credential-stuffing attacks or phishing attempts, despite the hashing protection.
