Ofuscación de código utilizando generadores de números pseudoaleatorios
Code obfuscation using pseudo-random number generators
##plugins.themes.bootstrap3.article.main##
Se describe un nuevo método para la ofuscación de códigos maliciosos que utiliza códigos ya presentes en los sistemas: un generador de números pseudo-aleatorios. Esto también puede verse como una técnica anti-desmontaje y anti-depuración, dependiendo de su despliegue, debido a que el código real no existe hasta su ejecución - que se genera de forma dinámica por el generador de números pseudo-aleatorios. Se han usado xperimentos de todo un año para demostrar que esta técnica de ofuscación es viable para un adversario malicioso con acceso a una gran potencia computacional.
