Frequently Asked Questions and Answers

Program

About programs

  • Q What is a bug bounty program?

    A bug bounty program is an initiative that rewards hackers with monetary payment for finding and reporting a system vulnerability in a company’s web services or applications.

    Each company determines the amount of bounty payment in advance based on the vulnerability level, and only pays for valid reports, making it a highly cost-effective way to improve security.

    Vulnerability is a potential security flaw in a computer or software caused by program flaws or design flaws.

  • Q What conditions are required to qualify for a bounty reward?

    The client company must evaluate the bug report. To be eligible to receive bounty rewards, you must follow the conditions stipulated by the client company, and the reported bug must be recognized by the client company as a "valid bug", which can be reproduced and verified by the company.

  • Q Do you have any programs that offer non-monetary bounty rewards?

    Yes, we do. You can check the various bounty rewards available on the program information page. Program without bounty rewards have points rewards.

  • Q How are the "Ranking" determined?

    The ‘Hall of Fame’ rankings are based on the number of points the friendly hackers have received and are updated on a real-time basis.
