Dropbox also regularly conducts these bug hunts and it is an initiative that the company believes and trusts.

What is a Bug Bounty?

A bug bounty is a reward offered to a person who identifies an error or vulnerability within a computer program or network. HackerOne is a platform that has changed bug bounties and how hackers get rewarded, and as of right now there are over 390,000 registered hackers. More organizations, such as Dropbox, are participating in these bug bounties because it outlines threats and vulnerabilities in a network or system before they can be exploited by an attacker. Doing so also increases cybersecurity within the organization and makes all the networks or systems more secure.   


Dropbox paid over $320,000 in rewards and in many different areas.

  • Remote Code Execution - $32,768
  • Significant Authentication Bypass - $17,576
  • Trivial Remote Code Execution in Dropbox App - $15,625
