forensica-digital

Úsese para forensica digital autorizada, incluyendo volcados de memoria, líneas de tiempo de disco, investigación de PCAP, triaje de artefactos y preservación de evidencia para respuesta a incidentes.

¿Qué es forensica-digital?

Esta habilidad está diseñada para profesionales de ciberseguridad que realizan forensica digital autorizada y respuesta a incidentes (IR). Permite analizar volcados de memoria con Volatility 2/3, construir líneas de tiempo a partir de imágenes de disco (E01), investigar tráfico de red capturado en PCAP con tshark, y extraer artefactos críticos de sistemas Windows como Prefetch, Shimcache, registros de eventos y datos de navegación. La habilidad integra un flujo de trabajo claro: primero, preservar la evidencia mediante hashes SHA256 y copias de solo lectura; segundo, analizar memoria y artefactos de host; tercero, examinar la red; y finalmente, enriquecer los hallazgos con herramientas como Timeline Explorer, Eric Zimmerman tools, Autopsy o FTK Imager. Está pensada para integrarse con habilidades complementarias de análisis de malware, caza de amenazas e ingeniería inversa de protocolos, asegurando una cadena de custodia sólida y la extracción de Indicadores de Compromiso (IOC) útiles para la defensa.

Documentación

Forensica Digital y Artefactos de IR

ACCIÓN REQUERIDA (léase y ejecútese inmediatamente)

  1. NOW: Lea ../field-journal/precedent-pentest.md o la autorización de IR de la organización
  2. NOW: Confirme que es forensica/investigación y no escaneo ofensivo
  3. NOW: Establezca el caso; priorice copias de solo lectura de la evidencia (protección contra escritura del medio original)
  4. NEXT: index-tool; Volatility, etc., suelen ser manuales
  5. ACT: Preserve hash → línea de tiempo → artefactos clave

Escenarios de uso

  • Análisis de volcados de memoria (Volatility 2/3)
  • Líneas de tiempo de disco / E01 / archivos locales
  • Investigación de PCAP y reconstrucción de protocolos (puede combinarse con protocol-reverse/)
  • Artefactos de host: Prefetch, Shimcache, registros de eventos, historial del navegador
  • Extracción de IOC para respuesta a incidentes (combínese con malware-analysis/ / threat-hunting/)

Flujo de trabajo

1. Preservación

□ Calcule SHA256; registre la zona horaria y el comando de adquisición
□ Trabaje sobre copias; original solo lectura
□ Anote la cadena de custodia en la línea de tiempo

2. Memoria

vol -f mem.dmp windows.info
vol -f mem.dmp windows.pslist
vol -f mem.dmp windows.netscan
vol -f mem.dmp windows.cmdline

3. Artefactos de host

□ Registros de eventos: Seguridad / PowerShell / Sysmon
□ Persistencia: claves Run, servicios, tareas programadas, WMI
□ Huellas de ejecución: Amcache, Prefetch, BAM

4. Red

□ tshark para estadísticas de sesiones y DNS
□ Exporte flujos sospechosos → protocol-reverse o análisis de C2 de malware

Descendente: Profundización en muestras maliciosas → malware-analysis; reglas → threat-hunting

Autoverificación de finalización

  • ¿Se ha preservado el hash y la estrategia de copia?
  • ¿Es la línea de tiempo verificable?
  • ¿Se han desensibilizado y clasificado los IOC?
  • ¿Checklist?

Individual skills in this repo
