Steam is facing a potential data breach that may affect millions of users, reportedly linked to a third-party company associated with Valve, its parent organization. Discussions indicate that Two-Factor Authentication (2FA) data may have been leaked, with a user claiming to sell over 89 million user records on a dark web forum for ,000. Twilio, a company mentioned in connection with the breach, has denied any wrongdoing, stating there is no evidence of a breach on their end. Users are advised to enable 2FA, change passwords, and monitor email accounts for suspicious activity to protect against potential phishing attacks and account takeovers.
