Program Rules

Before you take any action in order to discover any security bug please note that, testing our systems may be seen as a criminal offence by the competent authorities. You should therefore keep in mind that our rules do not supersede any applicable laws. However, we are not going to report you to the authorities, if you obey the following rules and in case we are not required to do so by applicable laws. Although we appreciate your effort in improving our security we do not want our customers to be affected by any of your actions. In particular we want you to strictly comply with the following Do’s and Don’ts:


• Please provide detailed reports with reproducible steps.
• Submit one vulnerability per report, unless you need to chain vulnerabilities to provide impact.
• Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with explicit permission of the account holder.


• Violate any laws (including at least German and European law and any laws applicable in your country).
• Access or change accounts of other MediaMarkt/Saturn customers;
