Le chef du MI5 : l'IA « décuple » les menaces contre le Royaume-Uni, la Russie « agresseur n° 1 »

–

Résumé neutre

Dans son discours annuel d'évaluation des menaces du 13 octobre 2026, le directeur général du MI5, Sir Ken McCallum, a averti que l'intelligence artificielle « décuple » les menaces sécuritaires contre le Royaume-Uni, y compris la possibilité pour les terroristes et les États hostiles de créer de nouveaux biopathogènes létaux. Il a annoncé la création d'un nouveau Centre d'évaluation des menaces liées à l'IA au sein du MI5 pour examiner les opportunités et les risques découlant des progrès rapides de l'IA. McCallum a décrit la Russie comme l'« agresseur numéro un » et a déclaré que le MI5 alloue davantage de ressources pour contrer les menaces étatiques étrangères que pendant la guerre froide. Il a également noté un « changement majeur » dans les efforts de l'Iran, qui cible désormais des cibles plus difficiles comme les bases militaires, et une augmentation des menaces des extrémistes de droite aux opinions anti-migrants et anti-musulmanes, qualifiant cela de « tendance la plus marquée » de l'année écoulée. McCallum a déclaré que la Russie a tenté d'interférer dans le référendum sur le Brexit, mais sans en affecter le résultat. Les responsables russes ont rejeté ces allégations. Les sources varient dans leur accent : certaines mettent en avant la menace iranienne, d'autres la montée de l'extrémisme de droite, et d'autres encore les cybermenaces.
