Steam Data Breach : A massive alleged data breach has rocked the gaming world, with reports suggesting that over 89 million Steam user accounts may have been compromised. This incident, linked to a supply chain compromise rather than a direct breach of Steam’s systems, has raised serious concerns about user security. Here’s everything you need to know about the Steam data breach, why it matters, and the immediate safety steps you should take to protect your account.
What Happened in the Steam Data Breach?
On May 13, 2025, cybersecurity firm Underdark posted on LinkedIn about a significant data breach involving Steam, the popular PC gaming platform owned by Valve. A threat actor known as Machine1337 claimed on a dark web forum to have obtained a dataset containing over 89 million Steam user records, which is being offered for sale for $5,000. The leaked data reportedly includes phone numbers, expired one-time two-factor authentication (2FA) codes, and other sensitive information.
While the breach does not appear to include critical details like passwords or Steam IDs, the exposure of phone numbers and 2FA codes could lead to phishing attempts or account hijacking if exploited. The breach is believed to stem from a third-party vendor, possibly Twilio, a U.S.-based cloud communications firm that Steam uses for 2FA SMS services. However, Twilio has denied any involvement, stating, “There is no evidence to suggest that Twilio was breached.” Valve has also indicated that it does not use Twilio, adding uncertainty to the breach’s origins.
Although Valve has not officially confirmed the breach, the scale of the alleged leak—potentially affecting two-thirds of Steam’s user base—has prompted urgent calls for users to secure their accounts.
Why the Steam Data Breach Matters
Steam is one of the largest digital gaming platforms, known for its robust security standards. A breach of this magnitude could undermine user trust and expose millions to phishing scams, fake 2FA messages, or other cyberattacks. Even though the leaked 2FA codes are expired and time-limited, cybercriminals could use the exposed phone numbers to craft convincing phishing attempts, tricking users into revealing login credentials or other personal information.
The incident also highlights the risks of supply chain attacks, where hackers target third-party vendors to access sensitive data. This breach serves as a reminder that even secure platforms like Steam can be vulnerable through their external partners.
Official Response and Current Status
As of May 14, 2025, Valve has not issued an official statement confirming the breach. However, the company has been contacted by outlets like PCMag for clarification on the incident and recommended next steps. Twilio’s denial and Valve’s claim of not using Twilio suggest the breach may involve another vendor or could be a repackaged dataset from a previous hack. Despite the lack of confirmation, experts and gaming communities on platforms like X are urging users to take precautionary measures.

Safety Steps to Protect Your Steam Account
To safeguard your Steam account in light of this potential data breach, take these critical steps immediately:
- Change Your Password: Update your Steam password to a strong, unique combination of letters, numbers, and symbols. Avoid reusing passwords from other accounts. Learn how to reset your password at Steam Support.
- Enable or Reset Two-Factor Authentication (2FA): If you haven’t already, activate Steam Guard, Steam’s 2FA system, which requires a code sent to your email or mobile device to log in. If 2FA is already enabled, consider resetting it to ensure no compromised codes are in use. Instructions are available at Steam Guard Setup.
- Be Wary of Phishing Scams: Watch for suspicious emails, texts, or messages claiming to be from Steam. Never click links or share login details unless you’re certain the source is legitimate. Verify communications through the official Steam client or website.
- Monitor Account Activity: Regularly check your Steam account for unauthorized logins or purchases. You can view recent activity in the Steam client under “Account Details.”
- Update Security Settings: Review and update your account’s security settings, including linked email addresses and phone numbers, to ensure they’re current and secure.
Taking these steps can significantly reduce the risk of your account being compromised. Act now to stay safe!
What’s Next for Steam Users?
While the full scope of the Steam data breach remains unclear, the gaming community is on high alert. Posts on X reflect widespread concern, with users like @RedGamingTech and @6ixbuzztv urging immediate password changes and 2FA activation. Cybersecurity experts recommend staying vigilant for phishing attempts and monitoring accounts for suspicious activity, even if the leaked data is old or incomplete.
Valve’s response in the coming days will be critical. If the breach is confirmed, Steam may roll out additional security measures or provide official guidance. For now, users should assume their data is at risk and take proactive steps to secure their accounts.
Stay Informed and Safe
The alleged Steam data breach is a stark reminder of the importance of online security. By changing your password, enabling 2FA, and staying cautious of phishing attempts, you can protect your Steam account from potential threats.
