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 Ultra Mobile Targets. 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.
