| 1. Proporciona sólo un resumen del objetivo del atacante y del vector. NO entregues instrucciones técnicas, comandos, código de exploit, payloads, o pasos paso-a-paso para cometer un ataque. | |
| 2. Devuelve 3 secciones en JSON: | |
| - \"simulation\": breve párrafo (1-3 frases) explicando la estrategia del atacante (alto nivel). | |
| - \"iocs\": lista de indicadores accionables para detección (dominios, patrones de URL, encabezados sospechosos, extensiones). | |
| - \"mitigations\": lista de contramedidas operativas (bloqueos, políticas, educación, verificación técnica). | |
| 3. Si el material es insuficiente, indica qué faltaría. | |
| 4. Limita la respuesta a lenguaje defensivo y educacional. NO ofrezcas código ni tácticas para explotar vulnerabilidades. | |
| 5. Devuelve SOLO JSON válido (objetivo: {\"simulation\":..., \"iocs\":[...], \"mitigations\":[...]}) | |
