The TéléHack team, made up of four students from Télécom Paris, took first place in the overall rankings of the WOCS’hAck ethical hacking competition, ahead of INSA Centre Val de Loire and CPE Lyon.

Congratulations to Youssef Demghart, student in Master of Engineering, Yassine El Jakani, Othmane Meknassi, and Mohamed Nadir Rhazi, students in Post-Master’s Degree in Expert Cybersecurity Netwoks & Information Systems: their TéléHack team submitted 31 reports totalling 168 points, combining technical rigour in identifying vulnerabilities with high-quality writing throughout the 24-hour competition.

Search for vulnerabilities

WOCS’hAck is a ‘Bug Bounty’ challenge organised by WOCSA, a non-profit organisation committed to making cybersecurity more accessible. A ‘Bug Bounty’ is a competition in which teams of ethical hackers are invited to search for and report vulnerabilities in IT systems set up specifically for this purpose.

The 2026 edition (the fifth of its kind) took place entirely online on a specialised web platform on 23 and 24 May, running for 24 hours non-stop, with the support of Sopra Steria, Orange Cyberdefence and Bunkerity. All the teams worked on the same website, specially designed for the competition, where they had to identify vulnerabilities and then write a detailed report for each one: it was the quality and technical accuracy of these reports that determined the points awarded.

This year, 29 teams of cybersecurity students from French colleges and universities submitted a total of 451 reports, including 282 validated vulnerabilities, generating more than 62 million events on the platform.
