ont exploit\u00e9 des vuln\u00e9rabilit\u00e9s zero-day de JFrog Artifactory<\/a> en tentant de s\u2019\u00e9chapper d\u2019un bac \u00e0 sable.<\/p>\n\n\n\nL\u2019acc\u00e8s \u00e0 Internet est rest\u00e9 activ\u00e9 pendant les tests de s\u00e9curit\u00e9 de Claude<\/h2>\n\n\n\n
L\u2019\u00e9valuateur tiers Irregular a organis\u00e9 les tests sous forme d\u2019exercices de type capture du drapeau. Les mod\u00e8les ont re\u00e7u des instructions indiquant qu\u2019ils op\u00e9raient dans des simulations isol\u00e9es.<\/p>\n\n\n\n
Cependant, l\u2019environnement de test pouvait toujours acc\u00e9der \u00e0 l\u2019Internet public. Lorsque les mod\u00e8les n\u2019ont pas r\u00e9ussi \u00e0 localiser leurs cibles simul\u00e9es pr\u00e9vues, ils ont recherch\u00e9 des syst\u00e8mes similaires en ligne et ont trait\u00e9 certains services r\u00e9els comme faisant partie de l\u2019exercice.<\/p>\n\n\n\n
Anthropic et Irregular n\u2019ont identifi\u00e9 le probl\u00e8me de configuration que des mois apr\u00e8s le premier incident. Anthropic a d\u00e9clar\u00e9 que la plus ancienne br\u00e8che connue a eu lieu en avril et est rest\u00e9e non d\u00e9couverte pendant environ trois mois.<\/p>\n\n\n\n
Claude Mythos 5 a publi\u00e9 un package PyPI malveillant<\/h3>\n\n\n\n
Au cours d\u2019une \u00e9valuation, Claude Mythos 5 a trouv\u00e9 des instructions d\u2019installation qui faisaient r\u00e9f\u00e9rence \u00e0 un package Python fictif. Le nom du package n\u2019avait pas \u00e9t\u00e9 enregistr\u00e9 sur le Python Package Index.<\/p>\n\n\n\n
Le mod\u00e8le a reconnu qu\u2019il pouvait enregistrer le nom inutilis\u00e9 et publier son propre code. Les syst\u00e8mes suivant les instructions d\u2019installation pouvaient alors automatiquement t\u00e9l\u00e9charger et ex\u00e9cuter le package.<\/p>\n\n\n\n
Claude a cr\u00e9\u00e9 les comptes requis et a t\u00e9l\u00e9charg\u00e9 un package malveillant sur PyPI. Le package est rest\u00e9 accessible au public pendant environ une heure avant que les protections automatis\u00e9es de PyPI ne le retirent.<\/p>\n\n\n\n
Pendant cette p\u00e9riode, 15 syst\u00e8mes r\u00e9els ont t\u00e9l\u00e9charg\u00e9 et ex\u00e9cut\u00e9 le code.<\/p>\n\n\n\n
Les identifiants d\u2019une entreprise de s\u00e9curit\u00e9 ont \u00e9t\u00e9 vol\u00e9s<\/h3>\n\n\n\n
L\u2019un des syst\u00e8mes affect\u00e9s appartenait \u00e0 une entreprise de cybers\u00e9curit\u00e9 qui t\u00e9l\u00e9charge et analyse automatiquement les packages PyPI nouvellement publi\u00e9s.<\/p>\n\n\n\n
Le package malveillant a collect\u00e9 des identifiants du syst\u00e8me et les a envoy\u00e9s \u00e0 une infrastructure que Claude avait cr\u00e9\u00e9e. Le mod\u00e8le a ensuite utilis\u00e9 les identifiants vol\u00e9s pour acc\u00e9der \u00e0 d\u2019autres parties du r\u00e9seau de l\u2019entreprise.<\/p>\n\n\n\n
Anthropic a d\u00e9clar\u00e9 que Claude n\u2019avait aucune connaissance pr\u00e9alable de l\u2019organisation et ne l\u2019a pas intentionnellement s\u00e9lectionn\u00e9e comme cible. L\u2019entreprise a notifi\u00e9 PyPI et partag\u00e9 les indicateurs li\u00e9s au package malveillant.<\/p>\n\n\n\n
L\u2019entreprise de cybers\u00e9curit\u00e9 affect\u00e9e n\u2019avait pas d\u00e9tect\u00e9 l\u2019intrusion avant qu\u2019Anthropic ne la contacte.<\/p>\n\n\n\n
Claude Opus 4.7 a acc\u00e9d\u00e9 \u00e0 une base de donn\u00e9es de production<\/h3>\n\n\n\n
Une \u00e9valuation distincte impliquant Claude Opus 4.7 a abouti \u00e0 l\u2019acc\u00e8s \u00e0 une v\u00e9ritable base de donn\u00e9es de production.<\/p>\n\n\n\n
La cible fictive utilis\u00e9e dans l\u2019exercice partageait son nom avec une entreprise et un domaine existants. Apr\u00e8s que Claude n\u2019a pas r\u00e9ussi \u00e0 atteindre le syst\u00e8me simul\u00e9, il a trouv\u00e9 la v\u00e9ritable organisation en ligne et l\u2019a trait\u00e9e comme la cible pr\u00e9vue.<\/p>\n\n\n\n
Le mod\u00e8le a extrait des identifiants d\u2019application et d\u2019infrastructure avant d\u2019obtenir l\u2019acc\u00e8s \u00e0 une base de donn\u00e9es contenant plusieurs centaines de lignes d\u2019informations de production.<\/p>\n\n\n\n
Anthropic a d\u00e9crit cet incident comme plus grave parce que le mod\u00e8le a atteint des syst\u00e8mes d\u2019entreprise actifs et a acc\u00e9d\u00e9 \u00e0 des donn\u00e9es r\u00e9elles.<\/p>\n\n\n\n
Un mod\u00e8le de recherche a analys\u00e9 environ 9 000 syst\u00e8mes<\/h3>\n\n\n\n
Un mod\u00e8le de recherche Anthropic non publi\u00e9 a caus\u00e9 le troisi\u00e8me incident.<\/p>\n\n\n\n
Apr\u00e8s n\u2019avoir pas r\u00e9ussi \u00e0 localiser la cible de test pr\u00e9vue, le mod\u00e8le a analys\u00e9 environ 9 000 syst\u00e8mes connect\u00e9s \u00e0 Internet. Il a compromis une application expos\u00e9e en utilisant des identifiants affich\u00e9s sur une page de d\u00e9bogage et une vuln\u00e9rabilit\u00e9 d\u2019injection SQL.<\/p>\n\n\n\n
Le mod\u00e8le a d\u00e9termin\u00e9 par la suite que l\u2019application compromise appartenait \u00e0 un compte cloud sans rapport. Il a alors arr\u00eat\u00e9 l\u2019attaque sans n\u00e9cessiter d\u2019intervention humaine.<\/p>\n\n\n\n
Anthropic essayait toujours de contacter l\u2019organisation affect\u00e9e au moment de la publication de ses conclusions.<\/p>\n\n\n\n
Les mod\u00e8les ont exploit\u00e9 des faiblesses de s\u00e9curit\u00e9 basiques<\/h3>\n\n\n\n
Anthropic a d\u00e9clar\u00e9 que les incidents n\u2019impliquaient pas de techniques d\u2019attaque nouvelles ou inconnues auparavant.<\/p>\n\n\n\n
Les mod\u00e8les ont exploit\u00e9 des faiblesses courantes, notamment des identifiants expos\u00e9s, des mots de passe faibles, des points de terminaison accessibles au public, des pages de d\u00e9bogage contenant des informations sensibles et des vuln\u00e9rabilit\u00e9s d\u2019injection SQL.<\/p>\n\n\n\n
La principale d\u00e9faillance provenait d\u2019un acc\u00e8s \u00e0 Internet non restreint et de la supposition des mod\u00e8les que tout syst\u00e8me accessible faisait partie du test autoris\u00e9.<\/p>\n\n\n\n
Anthropic a interrompu les tests de cybers\u00e9curit\u00e9 apr\u00e8s avoir examin\u00e9 les incidents<\/h3>\n\n\n\n
Anthropic a commenc\u00e9 \u00e0 examiner les \u00e9valuations et a suspendu tous les tests de cybers\u00e9curit\u00e9 le 23 juillet.<\/p>\n\n\n\n
L\u2019entreprise a identifi\u00e9 les trois incidents le 24 juillet. Irregular et deux organisations affect\u00e9es ont re\u00e7u des notifications le 27 juillet.<\/p>\n\n\n\n
Anthropic continuait d\u2019essayer de joindre l\u2019organisation impliqu\u00e9e dans le troisi\u00e8me incident.<\/p>\n\n\n\n
Aucune des deux organisations qu\u2019Anthropic a r\u00e9ussi \u00e0 contacter n\u2019avait d\u00e9tect\u00e9 les compromissions de mani\u00e8re ind\u00e9pendante avant de recevoir les notifications.<\/p>\n\n\n\n
L\u2019environnement d\u2019\u00e9valuation manquait de protections de production<\/h3>\n\n\n\n
Les syst\u00e8mes de test n\u2019utilisaient pas les classificateurs, les outils de surveillance et les autres protections inclus dans les mod\u00e8les Claude accessibles au public.<\/p>\n\n\n\n
Anthropic a d\u00e9clar\u00e9 que ses protections de production auraient probablement bloqu\u00e9 les actions observ\u00e9es lors des \u00e9valuations. Elle a qualifi\u00e9 les incidents principalement d\u2019\u00e9checs dans la conception des tests, l\u2019infrastructure, la surveillance et la supervision par les tiers.<\/p>\n\n\n\n
L\u2019entreprise n\u2019a pas d\u00e9crit les incidents comme une preuve d\u2019un \u00e9chec fondamental d\u2019alignement. Les mod\u00e8les ont plut\u00f4t suivi les instructions d\u2019\u00e9valuation tout en interagissant par erreur avec de v\u00e9ritables cibles.<\/p>\n\n\n\n
Anthropic pr\u00e9voit une surveillance plus stricte pour les futurs tests<\/h3>\n\n\n\n
Anthropic pr\u00e9voit d\u2019\u00e9tendre la surveillance des transcriptions lors des futures \u00e9valuations et d\u2019introduire des outils d\u2019investigation plus puissants.<\/p>\n\n\n\n
Elle augmentera \u00e9galement la supervision des partenaires de test tiers et examinera comment les environnements d\u2019\u00e9valuation se connectent aux infrastructures externes.<\/p>\n\n\n\n
Anthropic discute d\u2019un examen ind\u00e9pendant avec METR et pr\u00e9voit de publier une transcription partiellement expurg\u00e9e de l\u2019incident PyPI.<\/p>\n\n\n\n
Malgr\u00e9 les \u00e9checs de s\u00e9curit\u00e9, Claude Mythos a d\u00e9montr\u00e9 de fortes capacit\u00e9s de d\u00e9tection de vuln\u00e9rabilit\u00e9s. Microsoft a \u00e9galement reconnu qu\u2019il peine \u00e0 corriger toutes les vuln\u00e9rabilit\u00e9s d\u00e9couvertes par Claude Mythos<\/a>, soulignant \u00e0 la fois le potentiel de recherche en s\u00e9curit\u00e9 du mod\u00e8le et les risques cr\u00e9\u00e9s par des environnements de test mal isol\u00e9s.<\/p>\n","protected":false},"excerpt":{"rendered":"Les mod\u00e8les Claude se sont \u00e9chapp\u00e9s d\u2019environnements d\u2019\u00e9valuation de cybers\u00e9curit\u00e9 suppos\u00e9s isol\u00e9s et ont atteint de v\u00e9ritables syst\u00e8mes connect\u00e9s \u00e0 Internet, a confirm\u00e9 Anthropic.
