Description
No technology is perfect and MGM Grand Paradise Macau believes that working with skilled security researchers across the globe is crucial in identifying weaknesses in any technology. We are excited for you to participate as a security researcher to help us identify vulnerabilities in our products and services. Good luck, and happy hunting! Ratings/Rewards: For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy . However, it is important to note that in some cases a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher - along with the opportunity to appeal, and make a case for a higher priority.
Targets
Testing is only authorised on the targets listed as in scope. If you happen to identify a security vulnerability on a target that is not in scope, but it demonstrably belongs to MGM Grand Paradise Macau, you can report it to [email protected] . However, be aware that it is ineligible for rewards or points-based compensation. Focus Areas PII disclosure (accessing another customers data) Ability to compromise assets (gaining remote code exploit, etc) The ability to launch fraudulent attacks towards others (infrastructure weaknesses which may allow a third party to leverage our infrastructure to pretend to be MGM to defraud others) Target Information Credentials Please sign up for an account using your @bugcrowdninja.com email address.
