Students<\/strong><\/h2>\n\n\n\n<p>Cyberstorm brought together around <strong>sixty students<\/strong> who took on a series of <strong>technical challenges in the field of cybersecurity<\/strong>. Designed for beginner and intermediate profiles, the competition aimed above all to provide an accessible environment for <strong>learning, practising, and engaging<\/strong> with topics such as cryptography, forensics, and vulnerability analysis.<\/p>\n\n\n\n<p>The focus was on education and collaboration: participants evolved in a friendly, supportive atmosphere, encouraging knowledge-sharing and collective progress.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>A Great Success for an Ambitious Student Project<\/strong><\/h2>\n\n\n\n<p>Cyberstorm was conceived and led by first-year <a href=\"https:\/\/cyberschool.univ-rennes.fr\/en\/education\/cybersecurity-training-programmes\/masters-cybersecurity-science-of-software-and-hardware-security\/\" target=\"_blank\" rel=\"noreferrer noopener\">Master\u2019s students in Cybersecurity, Science of Software and Hardware Security<\/a>, as part of their programme at <a href=\"https:\/\/istic.univ-rennes.fr\/\" target=\"_blank\" rel=\"noreferrer noopener\">ISTIC<\/a> (<a href=\"https:\/\/www.univ-rennes.fr\/\" target=\"_blank\" rel=\"noreferrer noopener\">University of Rennes<\/a>) and within the CyberSchool consortium.

The objective was clear: to offer a valuable first CTF experience, without pressure, and accessible to students curious about cybersecurity.<\/p>\n\n\n\n<p><strong>Congratulations to all participants for their commitment and sportsmanship!<\/strong> Special mention to the teams on the podium: <em>n0_1d34<\/em>, <em>418 I\u2019m a teapot<\/em>, and <em>Blackcypher<\/em>.<\/p>\n\n\n\n<p><strong>A big round of applause as well to the organisers for this promising first edition, which leaves us eager to see what comes next.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This Saturday, 17 May, marked the inaugural edition of Cyberstorm, a Capture The Flag (CTF) competition organised by students from the CyberSchool consortium (ISTIC | University of Rennes).<\/p>\n","protected":false},"author":8,"featured_media":16676,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[2],"tags":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.13 -
