With cybercrime and major hacking incidents reaching epidemic proportions, the importance of locating application-layer vulnerabilities is rising. Developers and companies are constantly striving to scan their code and improve code integrity in the early development stages, but no application is completely vulnerability-free and external scrutiny is always a bonus.

This is where bug bounty programs come into play. Also known as Vulnerability Reward Programs (VRPs), these hacking events often produce alarming revelations that eventually end up preventing widespread damage to customers and companies alike. Security researchers, ethical hackers and enthusiasts from all over the world participate in these events for the benefit of all sides involved.

Checkmarx has brought together this bug bounty program list as a service to the ever-growing InfoSec community. Bug Bounty Program regulars from all over the world can use this comprehensive guide to plan their 2015 schedule and choose to divert their attention to the programs most relevant to their areas of expertise.

11. GitHub Security Bug Bounty

Languages: Ruby
Bounty: $100 USD (Minimum), $5,000 USD (Maximum)

GitHub is the world’s largest web-based code hosting service, used by developers all over the world, mostly for their open-source projects. It currently has around 3.4 million users with over 16 million repositories. Needless to mention, this platform requires bolstered security, which is why GitHub has its security bug bounty program.

This ever-growing bug-bounty community is nurtured by the creation of a unique point system. This involves a dynamic leaderboard that ranks the top participants of the program by awarding them points and badges for their achievements. There is also the bounty that is paid according to the severity of the vulnerability detected.

There are also many top software companies offering only official recognition to security experts who find flaws in their applications. They offer Hall of Fame status and also responsible disclosure acknowledgements.

Security researchers not primarily interested in the financial stimuli can opt for the following options:

  • Apple – The Cupertino giant doesn’t have a bug bounty program, but does accept vulnerability reports. Apple also promptly credits the researchers with full responsible disclosure and press releases on its official website.
  • AT&T – The American telecommunication company also has its bug hunting channel. Developers and InfoSec experts can research the various platforms, including its service-providing websites, exposed APIs and mobile applications.
  • Adobe – Adobe also has a responsible disclosure program in place for newly detected vulnerabilities in its website, applications and services. The findings are also published publically and researchers acknowledged officially.
  • eBay – Arguably the world largest e-commerce platform’s bug reporting program invites researchers to send in PoC’s and details of newly found vulnerabilities. Responsible disclosure acknowledgements are also on offer.
  • Deutsche Telecom – This German telecommunication giant also has its own bug bounty program, where researchers are required to locate flaws is the web portals of Deutsche Telekom AG in Germany (the domain).


It’s safe to say that bug bounty programs are gaining steam. Google recently announced that it has shelled out over $4 million in prize money, while introducing its new bounty programs for Android and iOS applications. The highest bounty paid to a single person so far is $150,000 USD, with the researcher also accepting an internship in the company.

Needless to say, this is not the complete solution as there is no substitute for secure coding and testing integrated into the Software Development Life Cycle (SDLC). But with more and more leading companies encouraging security research and promoting awareness amongst professionals and enthusiasts alike, the future is looking bright.
