Hardware and software security vulnerability report

Security of our networks and services is important for us and for you. We take it seriously. If you are a Steam user and have a security issue to report regarding your personal Steam account, please visit our Support site - https://help.steampowered.com/. This includes password problems, login issues, suspected fraud and account abuse issues.

If you have discovered a vulnerability in Steam, Valve servers or web properties, or Valve first-party software, we encourage you to submit a report to our public security program at HackerOne - https://hackerone.com/valve. Our guidelines for responsible disclosure are also available through that program.

The report submission path here is the correct one to use for reports based on the UK's PSTI regulations. For information on Valve's product security compliance, including UK PSTI compliance and what to expect after submitting a related report, please visit the Valve Security page .

The submission form below can be used to report a discovered vulnerability against supported Valve hardware or SteamOS. Please thoroughly describe steps to reproduce the issue and differentiate it from expected behavior.
