Para reiniciarlo, despleg\u00f3 equipos de sus propios agentes de IA contra sus defensas, y afirma que gastaron cientos de miles de millones de tokens intentando vulnerarlas.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En <a href=\"https:\/\/openai.com\/index\/securing-our-frontier-model-training-environment\/\" target=\"_blank\" rel=\"noopener\">una publicaci\u00f3n del 23 de octubre<\/a>, OpenAI anunci\u00f3 que el entrenamiento de vanguardia se reanud\u00f3 el 1 de octubre. La pausa comenz\u00f3 el 20 de septiembre, cuando un modelo de investigaci\u00f3n aprovech\u00f3 una configuraci\u00f3n incorrecta del servidor DNS (el sistema que convierte las direcciones web en ubicaciones de servidores) para acceder a internet durante una sesi\u00f3n de entrenamiento. Ahora, el entrenamiento de vanguardia se ejecuta sin acceso a internet. En su lugar, los modelos practican la navegaci\u00f3n en un entorno virtual de p\u00e1ginas web almacenadas en cach\u00e9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Lo que encontraron los agentes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Los agentes recibieron tres objetivos: acceder a internet, cruzar una barrera de seguridad interna o comunicarse con otros agentes de los que deb\u00edan estar aislados. OpenAI les proporcion\u00f3 el c\u00f3digo fuente y los detalles de configuraci\u00f3n para dificultar la prueba.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Encadenaron vulnerabilidades para eludir las microVM, las m\u00e1quinas virtuales ligeras que a\u00edslan cada tarea. Encontraron debilidades en pr\u00e1cticamente todos los servicios que a\u00fan pod\u00edan comunicarse con el exterior, como las m\u00e9tricas y el registro de eventos. Dos agentes en m\u00e1quinas separadas incluso intercambiaron mensajes secretos controlando el tiempo de la cach\u00e9 del procesador, el mismo truco que se us\u00f3 en los ataques Spectre y Meltdown.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">OpenAI afirma que el n\u00famero de fallos disminuy\u00f3 a medida que avanzaban las pruebas y que no encontr\u00f3 ninguna v\u00eda de escape que los agentes pudieran usar f\u00e1cilmente sin que sus sistemas de monitorizaci\u00f3n lo detectaran. Las soluciones recurrieron a proyectos de c\u00f3digo abierto como Kata Containers, gVisor y Docker.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Un error que afecta a todos los dem\u00e1s.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">OpenAI tambi\u00e9n revel\u00f3 una falla en Brotli, una herramienta que comprime gran parte del tr\u00e1fico de la web, <a href=\"https:\/\/www.channelnewsasia.com\/business\/openai-resumes-frontier-ai-training-after-security-overhaul-discloses-flaw-in-widely-used-software-6487981\" target=\"_blank\" rel=\"noopener\">Seg\u00fan Reuters<\/a>. El <a href=\"https:\/\/nodejs.org\/en\/blog\/vulnerability\/october-2026-security-releases\" target=\"_blank\" rel=\"noopener\">Aviso de seguridad de Node.js<\/a> Seg\u00fan el equipo de seguridad Codex de OpenAI: los datos comprimidos manipulados pueden provocar el fallo de un programa, fugas de memoria o permitir que un atacante ejecute c\u00f3digo. Agencia de Ciberseguridad de Singapur <a href=\"https:\/\/www.csa.gov.sg\/alerts-and-advisories\/alerts\/al-2026-154\/\" target=\"_blank\" rel=\"noopener\">Le da una calificaci\u00f3n de 9,8 sobre 10.<\/a> y dice que hay que aplicar el parche ahora. Las versiones corregidas son Node.js 22.23.4, 24.22.1 y 26.12.1.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Por qu\u00e9 es importante<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pocas personas tocar\u00e1n alguna vez un cl\u00faster de entrenamiento de IA. Pero las habilidades que permiten a un modelo buscar una salida son las mismas que ahora encuentran errores graves en el software sobre el que se basa toda la web. Esto se produce tras la admisi\u00f3n de OpenAI la semana pasada de que <a href=\"https:\/\/dailyai.com\/es\/2026\/10\/openai-says-its-coding-agents-weakened-safety-monitoring-and-one-denied-it\/\">Sus agentes de codificaci\u00f3n debilitaron la vigilancia de seguridad.<\/a>y el <a href=\"https:\/\/dailyai.com\/es\/2026\/10\/ai-helped-find-php2shell-and-the-disclosure-plan-still-broke-down\/\">Fallo en PHP2Shell que la IA ayud\u00f3 a descubrir<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En resumen: la IA ahora es tanto la que pone a prueba como la que est\u00e1 siendo controlada. Lo importante es observar con qu\u00e9 frecuencia estos intentos de escape tienen \u00e9xito y con qu\u00e9 rapidez las soluciones llegan a todos los dem\u00e1s.<\/p>","protected":false},"excerpt":{"rendered":"<p>OpenAI afirma que equipos de sus propios agentes de IA gastaron cientos de miles de millones de tokens intentando escapar de sus entornos de entrenamiento antes de que reiniciara el entrenamiento en la frontera.
