Un grupo de investigadores de seguridad del equipo uCode ha publicado los textos fuente para descifrar el microc\u00f3digo de Intel. Para extraer el microc\u00f3digo cifrado se puede utilizar la t\u00e9cnica Red Unlock, desarrollada por los mismos investigadores en 2020. La capacidad de descifrar el microc\u00f3digo propuesta permite explorar la estructura interna del microc\u00f3digo y los m\u00e9todos de implementaci\u00f3n de las instrucciones de m\u00e1quina x86. Adem\u00e1s, los investigadores han recuperado el formato de actualizaciones del microc\u00f3digo, el algoritmo de cifrado y la clave utilizada para proteger el microc\u00f3digo (RC4). <\/p>\n

Para determinar la clave de cifrado utilizada, se aprovech\u00f3 una vulnerabilidad en Intel TXE, que permiti\u00f3 activar un modo de depuraci\u00f3n no documentado, al que los investigadores le asignaron el nombre en c\u00f3digo \"Red Unlock\". En el modo de depuraci\u00f3n, se pudo cargar directamente desde el CPU un volcado del microc\u00f3digo en funcionamiento y extraer de \u00e9l el algoritmo y las claves. <\/p>\n

La herramienta solo permite descifrar el microc\u00f3digo, pero no ofrece la posibilidad de modificarlo, ya que la integridad del microc\u00f3digo se verifica adicionalmente mediante una firma digital basada en el algoritmo RSA. El m\u00e9todo es aplicable a los procesadores Intel de la familia Gemini Lake basados en la microarquitectura Goldmont Plus y a Intel Apolo Lake basados en la microarquitectura Goldmont.
