Pero aun no hemos tenido ninguna incidencia con este nuevo Magniber , Cerber o como se le quiera llamar, quizás por lo que vemos que indican sobre los idiomas de los ficheros que afecta:



"When first run, malc0de discovered that Magniber checks the language used when Windows was installed. If it is not Korean, it will terminate the process and not encrypt the computer. On the other hand, if it is Korean, it will generate a unique victim ID that will be used in the ransom notes and when accessing the TOR payment site"



"Kafeine and Joseph Chen discovered that Magniber is being distributed through malvertisements displayed by the Magnitude exploit kit that are specifically tageting users from South Korea. In a report by Trend Micro, fraud researcher Joseph Chen explains how the Magnitude exploit kit is currently focusing on victims in South Korea"



Se trata de un ataque dirigido solo a los usuarios de Corea del Sur ???



Por si acaso informamos al respecto para información de todos, coreanos o no !
