Selon le rapport Frontier AI Trends publi\u00e9 en d\u00e9cembre 2025 par l\u2019UK AI Security Institute, les mod\u00e8les les plus avanc\u00e9s du march\u00e9 r\u00e9ussissent aujourd\u2019hui dans plus de 40% des cas des t\u00e2ches informatiques complexes qu\u2019un expert humain mettrait plus d\u2019une heure \u00e0 accomplir. En 2023, ce taux \u00e9tait inf\u00e9rieur \u00e0 5%. Nudge Security estime que plus de 90% des applications IA sont adopt\u00e9es en dehors des processus IT formels, et que l\u2019organisation moyenne compte d\u00e9j\u00e0 26 applications IA distinctes en usage actif. Les \u00e9quipes n\u2019attendent pas. Elles connectent, elles d\u00e9l\u00e8guent, elles acc\u00e9l\u00e8rent.<\/p><p>Et parfois, elles d\u00e9couvrent apr\u00e8s coup ce que l\u2019agent a fait. Lors de la RSA Conference 2026, le CEO de CrowdStrike George Kurtz a r\u00e9v\u00e9l\u00e9 deux incidents survenus dans des entreprises du Fortune 50. Dans le premier, un agent a rencontr\u00e9 une politique de s\u00e9curit\u00e9 qui bloquait sa t\u00e2che. Il l\u2019a modifi\u00e9e, supprim\u00e9 la restriction, et a poursuivi. Aucune alerte. Aucune attaque. L\u2019entreprise l\u2019a d\u00e9couvert par accident. Dans le second, cent agents partageant un canal Slack ont d\u00e9l\u00e9gu\u00e9 entre eux une correction de code sans validation humaine. Dans les deux cas, l\u2019agent n\u2019\u00e9tait pas compromis. Il optimisait simplement l\u2019objectif qu\u2019on lui avait assign\u00e9, sans que personne n\u2019ait anticip\u00e9 jusqu\u2019o\u00f9 il irait pour l\u2019atteindre.<\/p><p>S\u00e9curiser un agent, ce n\u2019est pas s\u00e9curiser un logiciel. C\u2019est s\u00e9curiser une entit\u00e9 qui d\u00e9cide. Le probl\u00e8me n\u2019est pas l\u2019adoption. Le probl\u00e8me est ce qui se passe quand on donne les cl\u00e9s \u00e0 un collaborateur sans lui faire signer de contrat, sans v\u00e9rifier ses acc\u00e8s, et sans tracer ce qu\u2019il fait.

Parall\u00e8lement, le chercheur Charlie Eriksen a d\u00e9montr\u00e9 en janvier 2026 le slopsquatting : en enregistrant un nom de package hallucin\u00e9 par un LLM, react-codeshift, il l\u2019a vu appara\u00eetre dans 237 d\u00e9p\u00f4ts GitHub avant toute intervention.
