Bug Bounty Hunters, also known as cybersecurity bounty hunters, are computer security experts who specialise in detecting vulnerabilities in computer systems, software or web applications. Their aim is to find vulnerabilities before they are exploited by cybercriminals.
Often freelance or self-employed, Bug Bounty Hunters use advanced techniques such as penetration testing, source code analysis and reverse engineering to identify weak points in systems. In exchange for their discoveries, they receive financial rewards in proportion to the seriousness of the vulnerabilities reported.
This profession belongs to the field of IT testing.
The bug bounty hunter needs to have a hacker's mindset, combining curiosity and creativity to analyse how systems work and discover vulnerabilities. Patient and persevering, they are capable of spending hours, even days, analysing environments with no immediate guarantee of success, but with the ability to handle pressure and stay motivated.
With excellent analytical and problem-solving skills, they propose solutions to correct vulnerabilities. They are comfortable with written and oral communication, writing reports and working with development and security teams. Autonomous and organised, they know how to manage their time and priorities.
Finally, to ensure that any vulnerabilities discovered are disclosed and that confidentiality rules are respected, you will demonstrate impeccable ethical standards.
This profession requires 2 to 5 years' higher education, with a background in IT and cybersecurity. Some candidates manage to succeed without a degree, thanks to their practical experience and self-taught skills.
Among the specialist schools, Guardia Cybersecurity School offers courses such as the Bachelor's degree in IT Development with Cybersecurity option and the MSc Cybersecurity Expert, which combine theory and practice. IMERIR (Perpignan) offers courses ranging from bac +2 to bac +5, with diplomas awarded by the Conservatoire National des Arts et Métiers (CNAM).
To complete their training, bug bounty hunters can obtain recognised certifications attesting to their expertise in penetration testing, web application security and vulnerability research.
