Qu’est-ce qu’une vulnérabilités 0-day

ITCOM

En règle générale, un logiciel malveillant repose sur l’exploitation d’une ou deux failles de sécurité qui ont déjà été documentées et même corrigées. Parfois, le virus exploite une vulnérabilité inédite : on parle alors de faille 0-day (zero day), dont l’exploitation à grande échelle est un événement. Stuxnet exploite quant à lui quatre vulnérabilités 0-day affectant les environnements Windows : du jamais vu, qui témoigne d’un niveau de renseignement bien supérieur à celui des cyberattaques courantes.

Au fil des analyses, le code source de Stuxnet livre petit à petit ses secrets. Au premier niveau, le logiciel est conçu pour se répliquer et peupler les machines qui habitent l’intérieur d’un réseau informatique : la mécanique virale est impressionnante d’efficacité, mais elle reste assez classique.
