Claude Mythos peut encha\u00eener quatre vuln\u00e9rabilit\u00e9s du jour au lendemain. Le projet Glasswing d\u2019Anthropic signale que le mod\u00e8le de s\u00e9curit\u00e9 de Web3 est d\u00e9j\u00e0 obsol\u00e8te.<\/strong><\/em><\/p>\n

Anthropic a discr\u00e8tement confirm\u00e9 quelque chose que l’industrie de la blockchain aurait d\u00fb redouter. Son mod\u00e8le fronti\u00e8re in\u00e9dit, Claude Mythos, a franchi un seuil que les chercheurs en s\u00e9curit\u00e9 ont pass\u00e9 des ann\u00e9es \u00e0 esp\u00e9rer ne jamais atteindre. Les ing\u00e9nieurs n\u2019ayant aucune exp\u00e9rience en mati\u00e8re de s\u00e9curit\u00e9 peuvent d\u00e9sormais le d\u00e9clencher du jour au lendemain et se r\u00e9veiller avec un exploit d\u2019ex\u00e9cution de code \u00e0 distance fonctionnel.<\/span><\/p>\n

Ce n\u2019est pas un avertissement pour l\u2019avenir. C’est d\u00e9j\u00e0 arriv\u00e9.<\/span><\/p>\n

Selon<\/span> alicharts sur X<\/span><\/a>, Mythos a identifi\u00e9 un bug vieux de 27 ans dans OpenBSD qui avait \u00e9t\u00e9 manqu\u00e9 par les auditeurs humains pendant des d\u00e9cennies. Le m\u00eame mod\u00e8le a encha\u00een\u00e9 quatre vuln\u00e9rabilit\u00e9s distinctes pour \u00e9chapper au bac \u00e0 sable du navigateur. Cette t\u00e2che prend g\u00e9n\u00e9ralement des mois \u00e0 des \u00e9quipes humaines d\u2019\u00e9lite.<\/span><\/p>\n

La chose Web3 refuse d’admettre<\/b><\/h2>\n

Anthropique<\/span> a publi\u00e9 les d\u00e9tails directement<\/span><\/a>. Le langage \u00e9tait d\u00e9lib\u00e9r\u00e9 et dur. Mythos Preview avait d\u00e9j\u00e0 d\u00e9couvert des milliers de vuln\u00e9rabilit\u00e9s de grande gravit\u00e9, dont certaines dans tous les principaux syst\u00e8mes d’exploitation et navigateurs Web. Les protocoles blockchain, qui d\u00e9pendent d\u2019audits humains p\u00e9riodiques, se situent directement dans cette ligne de mire.<\/span><\/p>\n

Le projet Glasswing est la r\u00e9ponse. Amazon Web Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, Microsoft, NVIDIA, Palo Alto Networks et la Linux Foundation se sont joints \u00e0 cet effort. Anthropic a engag\u00e9 jusqu’\u00e0 100 millions de dollars en cr\u00e9dits d’utilisation pour le d\u00e9ploiement d\u00e9fensif du mod\u00e8le. Quatre millions de dollars suppl\u00e9mentaires ont \u00e9t\u00e9 directement vers\u00e9s aux organisations de s\u00e9curit\u00e9 open source.<\/span><\/p>\n

Le cadrage d\u2019Anthropic \u00e9tait clair. Les capacit\u00e9s d\u2019IA telles que Mythos prolif\u00e9reront et atteindront des acteurs qui ne sont pas d\u00e9termin\u00e9s \u00e0 les d\u00e9ployer en toute s\u00e9curit\u00e9. Les cons\u00e9quences sur la s\u00e9curit\u00e9 publique et nationale pourraient \u00eatre graves.<\/span><\/p>\n

Exploitez les revenus des attaques assist\u00e9es par l\u2019IA sur<\/span> Contrats intelligents blockchain<\/span><\/a>a doubl\u00e9 environ tous les 1,3 mois. Cette trajectoire est ant\u00e9rieure \u00e0 la publication de Mythos.<\/span><\/p>\n

Les audits p\u00e9riodiques sont d\u00e9j\u00e0 morts<\/b><\/h2>\n

Comme l\u2019a not\u00e9 Alicharts sur X, le mod\u00e8le traditionnel d\u2019examens de s\u00e9curit\u00e9 p\u00e9riodiques est termin\u00e9. Les protocoles blockchain qui n\u2019int\u00e8grent pas de protection autonome contre l\u2019IA dans leur pile seront mis \u00e0 part par la prochaine g\u00e9n\u00e9ration d\u2019agents antagonistes. Le post X a d\u00e9crit Mythos comme un tueur de cat\u00e9gorie, sp\u00e9cifiquement en raison de sa capacit\u00e9 de cha\u00eene d’attaque en plusieurs \u00e9tapes.<\/span><\/p>\n

Cela correspond \u00e0 ce que<\/span> PDF de recherche d’Anthropic<\/span><\/a>montre. L\u2019\u00e9tude Mythos Preview a signal\u00e9 que l\u2019acc\u00e9l\u00e9ration \u00e9tait suffisamment forte pour n\u00e9cessiter une action imm\u00e9diate, et non apr\u00e8s la prochaine violation majeure du protocole.<\/span><\/p>\n

Le<\/span> Page d’aper\u00e7u de Glasswing<\/span><\/a>a clairement formul\u00e9 le probl\u00e8me principal\u00a0: la capacit\u00e9 de codage de l\u2019IA a d\u00e9pass\u00e9 tous les humains, sauf les plus comp\u00e9tents, dans la recherche et l\u2019exploitation des vuln\u00e9rabilit\u00e9s. Les protocoles Web3, dont beaucoup s\u2019appuient encore sur des audits tiers peu fr\u00e9quents, n\u2019ont pas \u00e9t\u00e9 con\u00e7us en tenant compte de ce mod\u00e8le de menace.<\/span><\/p>\n

Le protocole de pr\u00eat Moonwell DeFi a perdu environ 1,78 million de dollars dans un incident distinct mais connexe li\u00e9 au code assist\u00e9 par l’IA. L’auditeur de contrats intelligents Pashov a signal\u00e9 sur X ce qu’il a d\u00e9crit comme \u00e9tant peut-\u00eatre le premier exploit directement li\u00e9 \u00e0 Solidity cod\u00e9 par ambiance. L’examinateur humain a quand m\u00eame sign\u00e9. C\u2019est l\u2019\u00e9cart qu\u2019exploite Mythos. L’image compl\u00e8te de la fa\u00e7on dont<\/span> Claude remod\u00e8le d\u00e9j\u00e0 l’audit du code Web3<\/span><\/a>se d\u00e9veloppe depuis des mois.<\/span><\/p>\n

Un effort de d\u00e9fense de 100 millions de dollars, aucune garantie<\/b><\/h2>\n

Quarante organisations suppl\u00e9mentaires qui construisent ou maintiennent une infrastructure logicielle critique ont obtenu un acc\u00e8s anticip\u00e9 \u00e0 Mythos Preview pour une analyse d\u00e9fensive. Anthropique \u00e9tait explicite. Aucune organisation ne peut r\u00e9soudre ce probl\u00e8me \u00e0 elle seule. Les capacit\u00e9s de Frontier AI devraient progresser consid\u00e9rablement au cours des prochains mois.<\/span><\/p>\n

Web3 n\u2019est pas nomm\u00e9ment inclus dans la coalition Glasswing initiale. Cette absence est r\u00e9v\u00e9latrice.<\/span><\/p>\n

La course entre les attaques assist\u00e9es par l\u2019IA et la d\u00e9fense assist\u00e9e par l\u2019IA est d\u00e9sormais le seul audit qui compte. Les protocoles blockchain reposant sur des examens de s\u00e9curit\u00e9 manuels fonctionnent avec un mod\u00e8le qui \u00e9tait d\u00e9j\u00e0 obsol\u00e8te avant l’annonce de Mythos.<\/span><\/p>\n
