Pwn2Own : The greatest Hackers Reward Program

Pwn2Own is a computer hacking contest held annually at the CanSecWest security conference, beginning in 2007. Contestants are challenged to exploit widely used software and mobile devices with previously unknown vulnerabilities. Winners of the contest receive the device that they exploited, a cash prize, and a “Masters” jacket celebrating the year of their win. The name “Pwn2Own” is derived from the fact that contestants must “pwn” or hack the device in order to “own” or win it. The Pwn2Own contest serves to demonstrate the vulnerability of devices and software in widespread use while also providing a checkpoint on the progress made in security since the previous year.

Contest dates for the year 2014:

The contest will take place March 12-13 in Vancouver, British Columbia, at the CanSecWest 2014 conference. The schedule of contestants and platforms will be determined by random drawing at the conference venue and posted at Pwn2Own.com  prior to the start of competition.

Rules and prizes:

The 2014 competition consists of three divisions: Browsers, Plug-Ins, and the Grand Prize. All target machines will be running the latest fully patched versions of the relevant operating systems (Windows 8.1 x64 and OS X Mavericks), installed in their default configurations. The vulnerability or vulnerabilities used in each attack must be unknown and not previously reported to the vendor. A particular vulnerability can only be used once across all categories.

The first contestant to successfully compromise a target within the 30-minute time limit wins the prize in that category.

The 2014 targets are:

Browsers:

Google Chrome on Windows 8.1 x64: $100,000

Microsoft Internet Explorer 11 on Windows 8.1 x64: $100,000

Mozilla Firefox on Windows 8.1 x64: $50,000

Apple Safari on OS X Mavericks: $65,000

Plug-ins:

Adobe Reader running in Internet Explorer 11 on Windows 8.1 x64: $75,000

Adobe Flash running in Internet Explorer 11 on Windows 8.1 x64: $75,000

Oracle Java running in Internet Explorer 11 on Windows 8.1 x64 (requires click-through bypass): $30,000

“Exploit Unicorn” Grand Prize:

SYSTEM-level code execution on Windows 8.1 x64 on Internet Explorer 11 x64 with EMET (Enhanced Mitigation Experience Toolkit) bypass: $150,000*

Make free calls from your computer to any mobile

Everyone of us make calls daily to our family members,friends and many other persons.

What if we could make free calls to everyone??Yes,you heard it correct only.FREE CALLS.

There is an online service that allows you to make calls for free just as we send SMS from way2sms.

It is NumberTank .

NumberTank allows you to make calls to any mobile(India,US,Canada) for free. You can make calls directly to the mobiles by simply entering the number.But the other party also should be signed up with NumberTank. Receiver need not be connected to internet.

Also there is no unnecessary processing done in connecting your call like the system calling the other person and keeping him in hold and calling you and connecting both of you as done in SITE2SMS.

Receiver receives the call just as you have called from your mobile.

All you need to do is signup with your email id and verify your mobile number. For signing up,you require invite from an existing customer or from the service itself.Existing customer invites are processed within seconds.

You will get 30 minutes of free talktime daily. And the unused minutes will be added upto the next day.
But at any point of time you can have only 100 minutes of talktime in your account.

All you need is your computer with a microphone connected to it!!! :)

Also one doesn't have to recharge their mobiles forever if they could manage with the free minutes of talktime offered by this.

People living out of INDIA can also signup for this and they can call their family members or friends directly without they having internet connection,asking them to come on to skype.  :)

Now that NumberTank has released their app for Android, they have shut down their website to make calls.

Prank to Restart your Windows Computer repititively

We all know that we can shutdown or restart any computer by executing simple run commands.
But how would it be if we are going to use the same commands to do something unnatural altering your computer's performance.

We are going to use the run commands to play a prank on a computer to automatically shutdown after booting or restart after booting.

We achieve this by writing a simple batch file. A Batch file (filename.bat) is a file  containing instructions that are directly executed on command prompt. So we keep the instructions that we want to execute in a simple notepad file and going to save it with some file name. Now our work is to place the file into startup folder of your windows operating system.

Steps to follow:

1. Open notepad
2. copy and paste the follow the following code in bold letters

@echooff

shutdown -r -f -t 300 -c "Message"

In the above code -r stands for restarting, -f for force shutting down the computer, -t for time in seconds, -c for comments where in you can embed your own message to surprise your friend.

Instead of -r attribute, -s can be used to shutdown the computer.

Now save the file as shutdown.bat and place it in the startup folder of your computer. The items in startup items will be run automatically whenever the computer starts.

DOWNLOAD THE FILE FROM HERE

Startup item locations:

• WINDOWS XP : C:\Documents and Settings\(user)\Start Menu\Programs\Startup
• WINDOWS 7 & 8 : C:\Users\(User-Name)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

To remove that startup item you may have to go to same folder and delete it. So, be careful when giving the time attribute and give appropriate time so that you can navigate to that folder and remove it. Else you have to restart your computer in safe mode and remove that file.

Thank You :)

Improve Web Browsing Experience with OneTab for Chrome

We all browse internet everyday for exploring information and we go through a lot of websites and in addition we are logged into our social network accounts like Facebook , Google + .

After opening a no of tabs in our browser the memory used by it increases and the browser slows down. But actually we will be on a single tab any instance of time.

OneTab is an extension for chrome that groups all the opened tabs into a single tab in a list form. By this it reduces almost 95% of memory used by web-browser.

As tabs are grouped into a single page as list , no scripts will be running when in background. This also improves the performance of your system when it is resuming from sleep mode.

You can also share all the links as a webpage instead of copying and pasting each and every link !!!!!!

It is free and no signup is required. Your data is not sent anywhere. So you need not worry about privacy.


OneTab Extension for Chrome

Hope this post helps improving your browsing experience... :)

Euclidean Algorithm to compute GCD of 2 numbers

Euclidean Algorithm

Here we assume that a is greater than b

(a>b)

gcd_euclid(int a, int b)
{
         if( b is 0) return a
     
        else
            {
              set value of a as b
              set value of b as a modulo b
            }
}

When 2 prime no's are taken,GCD is usually 1 and it can be seen from below example.... 

1. gcd_euclid(19,5)
2. gcd_euclid(5,19%5)
3. gcd_euclid(5,4)
4. gcd_euclid(4,5%4)
5. gcd_euclid(4,1)
6. gcd_euclid(1,4%1)
7. gcd_euclid(1,0)

return 1; //as b is 0.

GCD when 2 non prime no's are taken.....

1. gcd_euclid(30,5)
2. gcd_euclid(5,30%5)
3. gcd_euclid(5,0)

return 5; // as b is 0

Programmatic Implementation:

int euclid(int a, int b)
{
   while (b!=0)
   {
       int temp = b;
       int b = a%b;
       int a = temp;
   }

return a;
}

Thank You :)
