TRILOGIA DE FICHEROS QUE INTEGRAN NUEVA VARIANTE DE PROXY EXI

La nueva gama de los PROXI-EXI, derivados del backdoor CYCBOT, lo componen básicamente tres ficheros, dos de ellos de nombre y ubicación variable, y otro de nombre fijo LVVM.EXE y que si no se eliminan los tres, los restantes regeneran de nuevo el malware.

Con el ELISTARA 24.37 pasamos a controlar esta nueva variante
Los preanalisis de virus total de estos tres ficheros, ofrecen estos informes:
