Intrusion a BUll-ti

           

preface:

tenia una compañero que laburaba en bull (una empresa de origen francesa con sede en argentina) y su email era xxxxxxx@bull-ti.com.ar y un día recibo un email de el pero con otro dominio xxxxxx@integris.com.ar yo le envíe un email preguntándole si había cambiando de laburo me dijo que no ..... entonces empece a echarle el ojo a www.integris.com.ar claro ahora este era servidor de mail y www.bull-ti.com.ar  era la pantalla.... resumiendo bull-ti era un microsoft ventanas nt 4 con millones de fallos yo elegí el msadc.pl que me permitía ejecutar comandos como root, no perdon como administrador

aquí esta el exploit que use:

--------------------------corte aqui campeon---------------------------------------------

# Many thanks to Weld, Mudge, and Dildog from l0pht for helping me

# beta test and find errors!

Usage: msadc.pl -h <host> { -d <delay> -X -v }

-d <seconds> = delay between calls, default 1 second

-X = dump Index Server path table, if available

-N = query VbBusObj for NetBIOS name

-V = use VbBusObj instead of ActiveDataFactory

-v = verbose

-e = external dictionary file for step 5

Or a -R will resume a command session

gracias a este exploit le prendí el telnet

net start telnet

y vi sus dirs

En este server había un montón de info importante archivos .doc, .xls, .ppt yo me baje varios pero uno de los destacados era el que decía proyecto venezuela

y ya que hice 30 bueno hice 31 .....aquí esta el sam._

Actualmente bull-ti no usa mas iis lo cambiaron por otro.

bueno esto fue mi visita por la empresa bull me voy despiendo de sus server para no volver nunca mas...
