Le WiFi risque bien de rester durablement un mode de connexion extr\u00eamement peu s\u00e9curis\u00e9 : apr\u00e8s la d\u00e9couverte de failles autour du protocole de s\u00e9curit\u00e9 WPA2, son successeur, WPA3, devait permettre de r\u00e9hausser la s\u00e9curit\u00e9 des r\u00e9seaux sans fil – au prix d'une tr\u00e8s lente transition. Or, avant m\u00eame qu'il n'ai pu se g\u00e9n\u00e9raliser, des chercheurs ont d\u00e9couvert plusieurs failles qui permettent \u00e0 un attaquant de retrouver la cl\u00e9 du r\u00e9seau WiFi.\u00a0<\/strong><\/p>\n

\"WiFi<\/p>\n

La s\u00e9curit\u00e9 des r\u00e9seaux WiFi est durablement en pointill\u00e9s : en janvier 2017, un exploit du protocole de s\u00e9curit\u00e9 WPA2, Krack, avait fait les gros titres. Et pour cause : cette vuln\u00e9rabilit\u00e9 ouvre la voie \u00e0 toute une famille d'attaques simplifiant l'acquisition non autoris\u00e9e des cl\u00e9s WiFi par des pirates, baptis\u00e9es Key Reinstallation Attacks. Seule solution pour rem\u00e9dier au probl\u00e8me : mettre sur pied un nouveau protocole. Ainsi, d\u00e8s 2018, le WiFi Alliance lance WPA3<\/a>, nouvelle version du protocole qui s\u00e9curise les connexions aux r\u00e9seaux sans fil.<\/p>\n

Lire \u00e9galement :\u00a0faille Krack du Wi-Fi WPA2, qu'est-ce que c'est, quels appareils sont touch\u00e9s et comment se prot\u00e9ger ?<\/a><\/strong><\/p>\n
