Description
No technology is perfect and Ultra Mobile 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 program. 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 authorized on the targets listed as in scope. Any domain/property of Ultra Mobile not listed in the targets section is out of scope. This includes any/all subdomains not listed above. If you happen to identify a security vulnerability on a target that is not in scope, but it demonstrably belongs to Ultra Mobile, you can report it to our program. However, be aware that it is ineligible for rewards or points-based compensation.
