En examinant 76 000 vuln\u00e9rabilit\u00e9s identifi\u00e9es entre 2009 et 2018, il a \u00e9t\u00e9 d\u00e9termin\u00e9 que seulement 4 183 d'entre elles (5,5 %) avaient \u00e9t\u00e9 utilis\u00e9es pour mener des attaques r\u00e9elles. Ce chiffre est cinq fois sup\u00e9rieur aux pr\u00e9visions pr\u00e9c\u00e9demment publi\u00e9es, qui estimaient le nombre de probl\u00e8mes exploit\u00e9s \u00e0 environ 1,4 %.<\/p>\n<p>Aucune corr\u00e9lation n'a \u00e9t\u00e9 trouv\u00e9e entre la publication de prototypes d'exploits en acc\u00e8s libre et les tentatives d'exploitation des vuln\u00e9rabilit\u00e9s. Parmi tous les faits d'exploitation des vuln\u00e9rabilit\u00e9s connus des chercheurs, il n'y avait un prototype d'exploit publi\u00e9 dans des sources ouvertes que dans la moiti\u00e9 des cas. L'absence d'un prototype d'exploit n'emp\u00eache pas les attaquants qui, si n\u00e9cessaire, cr\u00e9ent des exploits par eux-m\u00eames.<\/p>\n<p>Parmi les autres conclusions, il convient de noter que les vuln\u00e9rabilit\u00e9s jug\u00e9es critiques selon la classification CVSS sont principalement celles qui sont exploit\u00e9es. Dans pr\u00e8s de la moiti\u00e9 des attaques, des vuln\u00e9rabilit\u00e9s avec un score d'au moins 9 ont \u00e9t\u00e9 utilis\u00e9es. <\/p>\n<p> Le nombre total de prototypes d'exploits publi\u00e9s pendant la p\u00e9riode \u00e9tudi\u00e9e est estim\u00e9 \u00e0 9 726. Les donn\u00e9es sur les exploits utilis\u00e9es dans l'\u00e9tude provenaient de<br \/>\ncollections Exploit DB, Metasploit, D2 Security's Elliot Kit, Canvas Exploitation Framework, Contagio, Reversing Labs et Secureworks CTU.<br \/>\nLes informations sur les vuln\u00e9rabilit\u00e9s ont \u00e9t\u00e9 obtenues \u00e0 partir de la base <noindex><a rel=\"nofollow\" href=\"https:\/\/nvd.nist.gov\/\">NIST NVD<\/a><\/noindex> (National Vulnerability Database). Les informations sur les faits d'exploitation ont \u00e9t\u00e9 r\u00e9sum\u00e9es sur la base des donn\u00e9es fournies par FortiGuard Labs, SANS Internet Storm Center, Secureworks CTU, OSSIM d'Alienvault et ReversingLabs.<\/p>\n<p>L'\u00e9tude a \u00e9t\u00e9 men\u00e9e afin de d\u00e9terminer l'\u00e9quilibre optimal entre l'application des mises \u00e0 jour lors de la d\u00e9tection de vuln\u00e9rabilit\u00e9s et la correction des probl\u00e8mes les plus dangereux uniquement. Dans le premier cas, une haute efficacit\u00e9 de protection est assur\u00e9e, mais des ressources consid\u00e9rables sont n\u00e9cessaires pour maintenir l'infrastructure, qui sont principalement d\u00e9pens\u00e9es pour corriger des probl\u00e8mes mineurs. Dans le second cas, il y a un grand risque de manquer une vuln\u00e9rabilit\u00e9 qui pourrait \u00eatre utilis\u00e9e pour une attaque. L'\u00e9tude a montr\u00e9 que lors de la d\u00e9cision d'installer une mise \u00e0 jour corrigeant une vuln\u00e9rabilit\u00e9, il ne faut pas se fier \u00e0 l'absence d'un prototype d'exploitation publi\u00e9, et le risque d'exploitation d\u00e9pend directement du niveau de danger de la vuln\u00e9rabilit\u00e9.<\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Source
