HACK CELLPHONE --- USING OLD TECHNIQUE

Namaste
During 90s phones and modems
were hacked using "AT"
commands.
So i thought if we can hack
cellfones using same old
technique.
The same "AT" instructions
work on cellfones as well, so
imagine what if we can call
someone or SMS someone using
computer system.
Well what is the hack in it?
Imagine if u develop a virus/
worm to exploit this
functionality! Imagine if u want
to earn money by forcing
victims to SMS on 5 or 4 or 3
digit special numbers.
Or u want to grab someones
password or credit card details
in SMS on ur cellfones.
And the possibilities are infinite.
The hack is very simple and is
versatile, i mean u can also call
any number using just ur
command console etc.
So let me demystify it..."vinnu"
Controlling Cellphones
Here in this topic I am not
introducing any new technique,
but same old fashioned way the
modems were hacked during
nintees.
Every microprocessor has
instruction set, likewise, every
modem has AT command set.
The AT stands for "Attention
Telephone"
or "Attention Terminal".
Here in this topic I'll show u the
ways to control the mobile
phone
using AT commands. This is the
way, u can develop ur own
custom applications
to control the device or
develop a virus/worm to exploit
the mobile devices.
Test Phone : Nokia N72,
SAMSUNG F270
For this purpose, it is necessary
to treat mobile device as a
modem and PC
treats the mobile device as a
modem.
We can do it in several ways,
from hyperterminal, command
console,
vbscript, c/c++ etc and many
more.
Now attach ur mobile phone to
PC and then fire up hyper
terminal from start\run
and type "hypertrm". Otherwise
open from Accessories
\communication.
when asked type any name and
press OK.
Then from next dialogue either
select from drop down list
either Mobile name or
the com3 (any one, both point
to mobile phone).
And from next window selet
following settings
"9600,8,None,1" and press Apply
and OK.
Now in hyperterminal window
type AT and press enter. If it
shows "OK", it means u r
now connected to mobile device
and it is ready to take
commands.
General purpose AT commands
are same you can search them
online (elite hackers already
know them),
but some commands are vendor
and device specific.
Now, If u want to call any
number then use the ATD or
ATDT or ATDP command.
Note: Remember to always
prefix "AT" to every instruction.
ATDT will use the tone dialing
whereas, ATDP will use pulse
dialing. ATD will use
the already set dialing either
by "ATT" or "ATP". By default, it
is tone dialing.
So if u want to call a number
9812312345 then use following:
ATD 9812312345
But this will envoke a data call
(usefull for connecting to
computer or servers or
dialup connection).
To start a voice call append a
semicolon ";" to number as:
ATD 9812312345;
This will start a voice call.
Hack using command
console..."vinnu"
But what if u want to call from
ur command console, it is even
more simple.
Start cmd.exe and fire up
following command:
echo ATD 9812312345;>com3
This will start a voice call from
command console.
Note: Check for com ports, in ur
case, if u already have other
devices connected even in USB,
then ur com port may differ.
To kcow the signal quality u can
use following command:
AT+CSQ
Ok What if i want to do same
using a vbscript, open notepad
and type following and save as
"cellfone.vbs":
set mcom=CreateObject
("MSCOMMLib.MSComm")
mcom.Settings="9600,n,8,1"
mcom.CommPort=3
'mcom.InBufferCount=0
mcom.PortOpen=True
If Err Then MsgBox "COnnection
at " & mcom.CommPort & ":
Failed" Else MsgBox "Dialing" End
If
WScript.Sleep(3000)
mcom.Output="ATD
01892202799;" & CHR(13)
WScript.Sleep(2000)
mcom.PortOpen=False
set mcomm=Nothing
Note: Here i have to append
integer value 13.
It will be converted into a
carriage return (Enter Key---
process the command).
Ok hat if we want to call using
c code.
Ok from operating system's
point of view, every port is a
file so let us read com port as
a file. And to send it a command
we'll write in the openned file
as:
/* fone.cpp */
#include < iostream >
using namespace std;
int main(int argc, char* argv[])
{
FILE *fp = NULL;
fp = fopen("com3","a");
if (fp != NULL) {
printf( "Dialing:...\n");
fprintf(fp,"atd 01892202799;\n")
;
fclose(fp);
}else printf("Failed");
return EXIT_SUCCESS;
}
Another program for reading
the output as well:
/* controlfon.cpp */
#include < iostream >
#include < windows.h >
using namespace std;
int main(int argc, char* argv[])
{
char buffer[32];
FILE *fp = NULL;
fp = fopen("com3","a");
if (fp != NULL) {
fprintf(fp,"at+csq\n");
fp = freopen("com3","r",fp);
memset(buffer,0,sizeof(buffer));
for(int a=0;(a=fscanf(fp,"%
s",buffer))>0;a=0){
printf("%s\n",buffer);
memset(buffer,0,sizeof(buffer));
Sleep(100);
}
printf( "Dialing:...\n");
fp = freopen("com3","a",fp);
fprintf(fp,"atd 01892202799;\n")
;
fclose(fp);
}
return EXIT_SUCCESS;
}
HAcking into SMS
system..."vinnu"
Now comming on to SMS service:
Cellphones use two modes for
operating on SMS:
1. PDU mode
2. Text mode
PDU : Protocol Data Unit but we
will not use it for the sake of
simplicity:
Text : This is the simplest way
and most of developers use this
way. We'll also use this way.
So let us start:
First of all, we need to set the
sms mode, we can do it wsing
AT+CMGF command and setting
its value to 0 for PDU otherwise
1 for text mode as:
AT+CMGF=1
Then we'll use the AT+CMGS
command then specify the
target cell number (recipient)
to send SMS to and then after
pressing enter a ">" prompt will
be shown, then write ur SMS
and when finished, press +Z.
AS shown below:
AT+CMGF=1
AT+CMGS="09816163963"
>Type ur message here+Z
Note: In ur case the com port
may differ, in my case one one
fone is at com3 and another at
com5 (Both are connected via
USB data cable), check all of
com ports like:
com3, com4, com5, com6...etc
And pass a command:
ATI
or ATI1
and check if ur cellphone's
brand name is returned as :
NOKIA
or
SAMSUNG etc.
