How to hack Wi-Fi using your Android smartphone

You Can Hack Wi-Fi Network and Crack Wi-Fi Password Using Your Android Smartphone

If you are a security researcher or hacker, you must have used Kali Linux tools to hack Wi-Fi for pentesting. However one of the most common comments/questions from our readers is for hacking Wi-Fi using Android smartphones. Is it possible to hack Wi-Fi using Android? Yes! It is possible because Android kernel is based on Linux, therefore most of the tricks and hacks that are possible with Linux can be done with Android.
However, since Android smartphone is not as powerful as a PC, there are certain modifications needed and one of them is a rooted Android smartphone. Here are the some Apps which allow you to hack Wi-Fi passwords using your Android smartphone

Things You Need For Hacking WiFi from Your Android Smartphone

  • Android smartphone with Quad-core Processor and at least 2GB RAM
  • Your Android smartphone Must be Rooted
  • The Wi-Fi network signal you want to hack should be powerful

WPS Connect

Though many reviews may say this App is fake but this is a working App and can crack Wi-Fi passwords in minutes from your Android smarpthone. With this App you can hack Wi-Fi signals which  are WPS enabled.
WPS Connect
WPS Connect bypasses WPS security and gives you access to to the Wi-Fi without typing any password.

Wi-Fi Kill

WiFi Kill works by disabling other users using the same Wi-Fi connection giving you the maximum bandwidth available on that particular network. Download Wi-Fi Kill and kill other users connections with this App.

ZAnti

ZAnti is a hacking and pentesting tool from the house of Zimperium. ZAnti has been released as a complete mobile pentesting App but it is also capable of hacking Wi-Fi network password of your Android smarpthone.
ZAnti is also capable of hacking wi-fi network password from android mobile. This app is made for checking the security of your wi-fi network. With this app, you can disable other wi-fi connection like wifi kill.ZAnti is like a hacking mobile toolkit for hackers. If you want a hacking android app that can hack other user wifi network and you can do everything you want.
With this App you can hack into Wi-Fi networks to test their security as well as kill other connections pretty much like Wi-Fi Kill above. In addition to hacking Wi-Fi, ZAnti offers you many other pentesting options which you would love if your are a hacker/security researcher. You can also download ZAnti from here.
WIFI WPS WPA Tester works on normal Android smarpthones if you want to just connect an WPS/WPA enabled Wi-Fi network without knowing the password. If you have a rooted Android smartphone, you can view the hacked password.

This hack PINs which are calculated using following algorithms:
-Zhao
-TrendNet
-Dlink
-Arris

Above are some of the Apps that let you hack your Wi-Fi network for testing purpose. Do not, REPEAT do not try hacking other networks as this may be illegal in your country and you could be jailed for the offence

Android Pattern Lock Can Be Easily Cracked In Five Attempts, Says Study


 

Researchers Show That Android’s Popular Pattern Lock Security Can Be Cracked Within 5 Attempts

Currently, Android is the most used mobile OS in the world, which means that it used by millions of devices worldwide. While Android devices provides PIN codes or text passwords to keep your device secure, it also offers a Pattern Lock system that allows you to create a password to protect your smartphone using various patterns of your choice.
Apparently, around 40 percent of Android device owners prefer using popular screen pattern lock as compared to using PIN codes or text passwords. Pattern lock is a screen unlock tool that allows user to unlock their touchscreen based devices such as smartphone or tablet by drawing a specific pattern using the nine dots divided into a 3×3 grid without lifting the finger.
While one may think that having screen pattern lock is more secure than using PIN codes or text passwords, then you may have to think again. According to a new research from Lancaster University, Northwest University in China, and the University of Bath, it is really easy to crack 95% of screen pattern locks within five attempts before the device gets locked by using video and computer vision algorithm software. What is worse that the more complicated patterns out there are even easier to figure out than the more simple Pattern Locks.
“Pattern Lock is a very popular protection method for Android Devices,” said Dr Zheng Wang, principle investigator and co-author of the paper at Lancaster University.
“As well as for locking their devices, people tend to use complex patterns for important financial transactions such as online banking and shopping because they believe it is a secure system.
“However, our findings suggest that using Pattern Lock to protect sensitive information could actually be very risky.”
To prove their research, the researchers secretly video recorded 120 participants when they were drawing their Pattern Lock shape to unlock their smartphone in a public place.They then used the finger print algorithm quickly track the owner’s fingertip movements relative to the device’s position and within seconds the algorithm came up with possible patterns that could unlock the smartphone or tablet.
The results were able to get accurate from video recorded on a smartphone from up to two and a half metres away. It also works reliably with footage recorded on a digital SLR camera at distances up to nine metres away.
Finally, the study also refutes the notion that using a complex pattern with more complicated shape is more secure. In fact, the researchers found that the most complex patterns are the easiest to be cracked. They were able to successfully crack 87.5 percent of median complex patterns and 60 percent of simple patterns with the first attempt.
“Contrary to many people’s perception that more complex patterns give better protection, this attack actually makes more complex patterns easier to crack and so they may be more secure using shorter, simpler patterns,” Guixin Ye, the leading student author from Northwest University, stated.
The researchers suggest that using a shorter and simple pattern is much better than using a complicated one. Besides this, the researchers also suggest users to completely cover their fingers when drawing the pattern to unlock the device. They also believe that fluctuating screen color and brightness could potentially confuse the cameras used by hackers. Also, other security measures “such as entering a sentence using Swype-like methods” can be used.

Here Is Why Your Computer Displays Correct Time Even When Turned On After Years

Wondered why your PC/laptop shows correct time even after being switched on after a year? Here is why!

Have you noticed a strange thing with your rarely used PC/laptop? If you have not used your PC/laptop a long period and you switch it on one day to find that it shows correct time? How can it do so without being connected to any electric outlet?
The reason for this is a timekeeper chip known as Real-time Clock or RTC. RTC is a semiconductor chip present on the motherboard which is assigned the job of keeping a note of the time when the computer disconnects from the power source. The Real-time Clock (RTC) or the CMOS ( Complementary Metal-oxide Semiconductor) chip by some manufacturers. In case it is a CMOS chip (known as CMOS RAM) it stores BIOS information of the computer in addition to the time. The RTC and CMOS have a very volatile memory and is powered by a CR2032 3V low voltage battery having a life of around ten years.
On desktop computers, the battery looks like a silver colored coin and is housed in the CPU itself or sometimes in the ATX tower.

The RTC chip is in compact form and irreplaceable, but you can replace the 2032 button cell if it gets exhausted.
Nowadays, the functions of RTC have been taken over by NTP time servers.. If you have set your time settings to automatic, the computer will connect to the NTS time servers and display the exact time. Single board computers like the Raspberry Pi or Android smartphones and iPhones don’t have RTC real-time clock chip. This is done to save the valuable space as well as sync time using Internet.
Older feature phones had the RTC powered by the mobile phone’s main battery. That’s the reason that every time you switched on or removed battery from your Nokia 1100, you had to set up the time and date.

How does Apple’s Mac keep time?

Apple’s Macs have their own distinct architecture to support the time function. In older Macs, the time is managed by a chip called PRAM or Parameter RAM. Similar to Windows run PCs, the PRAM chip on Macs is powered by a battery and keeps date and time information on the Macintosh machines. On newer Macs, the place of PRAM is taken by NVRAM (Non-Volatile RAM) which doesn’t require any battery to keep the data alive. The NVRAM can also store information, quickly like the screen resolution, speaker volume, startup disk selection, etc.
With Internet becoming a cornerstone of technology, the older RTC chips have given way to NTP Internet time.  Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over Internet. It has been in operation since 1985 and was designed by David L. Mills of the University of Delaware. NTP is so powerful that it synchronizes all connected computers to within a few milliseconds of Coordinated Universal Time (UTC). It uses a modified version of Marzullo’s algorithm to select accurate time servers and is designed to mitigate network latency. NTP can usually maintain time to within tens of milliseconds over the public Internet, and can achieve better than one millisecond accuracy in local area networks under ideal conditions.

Top 10 famous computer bugs that cost millions of dollars

Computer bugs or coding errors are a common phenomenon in the tech world as almost all software being developed have bugs. Any software which has a bug since the start of its lifecycle and is discovered later is called a zero-day.  Every day we hear such zero-days being discovered making it easy for hackers to hack into the system or your PC. Though such bugs cost big money, there are many such instances that such software errors have caused losses in millions of dollars. Today we bring to you 10 such famous and interesting bugs from the tech world.

Top 10 Famous Bugs in Tech World

1. Ariane 5 Crash

Top 10 Famous Bugs in Tech World
Arian 5 was the fifth in the Ariane series of European civilian expendable launch vehicles for space launch use and was to be used for launching satellites into space. The name comes from the French spelling of the mythological character Ariadne. On a sunny day in Kourou, French Guiana on June 4, 1996, the unmanned Ariane 5 exploded only about 40 seconds after its launch. This $500 million rocket exploded due to a very common software bug known as Integer Overflow. The internal SRI* software exception was caused during execution of a data conversion from 64-bit floating point to 16-bit signed integer value. The floating point number which was converted had a value greater than what could be represented by a 16-bit signed integer.

2. Patriot Missile Software Failure

Patriot Missile Software Failure
This software bug ended up causing more human loss than can be counted in money. 28 US military soldiers were killed and 98 were injured when an Iraqi missile hit their barracks because the missile system meant to protect them failed due to a software bug. The missile defense system called Patriot failed to track and intercept the incoming Iraqi missile due bug in Patriot’s radar and tracking software and failed to deploy on time.

3.Y2K Bug or Year 2000 Bug

This bug caused losses as well as gave rise to new breed of startups. In the late 90s, Y2K bug was perhaps the most talked about bug even as the world waited for airplanes to collide, ships to veer off course, stock markets to collapse as was forecasted by many tech experts. The bug was a simple mistake in the time management system of computers which used only two digits to represent the year. So 1970 would be represented as 70 and 1999 would be represented as 99.
This method worked fine till 31 Dec, 1999 but failed to take into consideration this millennium. Due to this bug, almost all computers which ran in those days would have read 1 January 2000 many 1 Jan 1900. The collapse never happened but it took a while for software developers to fix this bug.

4. PayPal Bug That Made a $92 Quadrillion deposit

Chris Reynolds' PayPal account was erroneously credited $92,233,720,368,547,800.
On a hot humid day in June 2013, Chris Reynolds got a fright of his life because his PayPal account showed a credit of  $92,233,720,368,547,800. The Pennsylvania PR executive’s account balance had swelled to a whopping $92,233,720,368,547,800. That’s a cool $92 QUADRILLION (and change).
The money was credited into Reynolds PayPal account due to a bug which catapulted him to become the world’s richest man till the fun lasted. Reynolds was richer a million times than world’s richest man at that time, Mexican telecom mogul Carlos Slim who worth $67 billion. PayPal admitted that the credit was due to a software bug and offered to donate an unspecified amount of money to a cause of Reynolds’ choice.

5. Gangnam Style broke YouTube

In 2014, YouTube was broken by a music video called Gangnam Style by Psy. YouTube developers built their platform on a 32-bit register, meaning that YouTube could track a range of -2,147,483,648 to 2,147,483,647 values for its view counter. Since one cannot, unfortunately, register a negative view on YouTube, this translated to a view-tracking capability of nearly 2.15 billion.
“We never thought a video would be watched in numbers greater than a 32-bit integer,” YouTube said in a Google+ post, “but that was before we met PSY.”  Google fixed this YouTube bug by changing the view count to a 64-bit signed integer.

6. Bug in Windows native calculator

This bug has not caused any loss but continues till date. Every version of Microsoft’s Windows operating software has a calculator which can’t give correct answer for square root(9)-3. The answer this arithmatic should be 0 but the Windows calculator doesn’t give 0 as an output. See the image below to understand the bug.
Bug in Windows calculator
The Calculator’s result is the same for any other number. For example answer of sqrt(4)-2 should be 0 but it won’t give 0 as an answer. This bug has been discovered years earlier but continues unabated even in Windows 10.

7. Year 2038 problem with 32-bit Unix computers

This time bug problem is similar to the Y2K bug issue we had in late 90s except that this is still to be patched. The world 32-bit computers could come to standstill on 19th January, 2038 as the time will end on that date. The Year 2038 problem is an issue for computing and data storage situations in which time values are stored or calculated as a signed 32-bit integer, and this number is interpreted as the number of seconds since 00:00:00 UTC on 1 January 1970 (the epoch). Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038.
According to software engineers, the Year 2038 bug doesn’t have a solution.

8. Software Race Condition Bug Creates Blackout for 50 Million People

On August 14, 2003, a blackout across eight US states and Canada affected 50 million people. PC Authority described the cause, a race condition bug, as something that occurs when “two separate threads of a single operation use the same element of code.” Without proper synchronization, the threads tangle and crash a system.
That’s what happened here with the result 256 power plants offline. The major disruptions manifested themselves in the form of cellular communication with the best form of communication during the outage said to be a laptop using a dial-up modem. And if you just cringed in horror at the word “dial-up,” you’re not alone.

9. $327 million Mars Climate Orbiter explosion due to software error

The Mars Climate Orbiter launched on December 11, 1998 by NASA to hunt for planets which can support human life. Unfortunately, due to an error in the ground-based computer software, the $327.6 million project — according to the NASA fact sheet — went missing 286 days later. Because of a miscalculation, Orbiter entered the Mars atmosphere at the wrong entry point and disintegrated shortly thereafter.

10.AT&T Nine Hour Outage due to a software bug

For nine hours in January 1990, AT&T customer in the United States could not make a long-distance calls. This paralysed the entire United States telephone network for a whole day. The root of the problem was a bug in the AT&T software that controlled the company’s long-distance relay switches—software that had just been updated. AT&T wound up losing $60 million in charges that day—a very expensive bug.
