The program, which is hosted by HackerOne, invites hackers to probe the main web domain, LinkedIn.com, for security flaws, as well as the LinkedIn API plus Android and iOS mobile apps.

Platform scoped with a wider range of vulnerabilities that includes “implementation and design issues that substantially impact LinkedIn members’ data or LinkedIn infrastructure” such as cross-site scripting (XSS), cross-site request forgery (CSRF), SQL injection, authentication, access control, and server-side code execution vulnerabilities.

Linkedin statement

The private program had since its launch awarded more than $250,000 across nearly 500 submissions covering the LinkedIn member platform and mobile applications, and because of the program’s success, we have decided to make the program public and expand participation to anyone wanting to report potential security vulnerabilities.

LinkedIn statement

LinkedIn, which connects business professionals with each other and job opportunities, was the source of two enormous data leaks in 2021, affecting 500 million and 700 million users respectively, but these were attributed to the scraping of public web pages rather than cyber-attacks.

But LinkedIn was blamed, both by security experts and members of the US Congress, over hacks that took place earlier. In the year 2012- initially, findings were that 6.4 million passwords were leaked, but in 2016 transpired to comprise emails and passwords belonging to 117 million users.
