Introduction

If we talk about smartphones and android devices, then there are billions of billions users using Android OS worldwide. 1.5 million android devices are getting activated daily including smartphones, tablets and android wearable. If you keep this figure in mind then there are billions of users using android OS. These figures show just how popular android is right now. People like this Operating System very much. But due to increase of users, security concerns are rising.

Figure 2: Rising

If we talk about global market share of Android devices, then it is more than 82% worldwide. It means most of the smartphone users using Android OS. But with this increase of users now a days, mobile security is also at risk because a bug called StageFright has been detected due to which mobile security of billions of android users is at risk and this article describes all about StageFright.

What is StageFright

According to Wikipedia.

• StageFright 1.0
• StageFright 2.0

StageFright 1.0

StageFright 1.0 fixed patch has been released from Google. StageFright chooses auto retrieval mms option of messaging app & chat apps to send malicious file into your Android device and silently get into it through the libStageFright mechanism (thus the “Stagefright” name), which helps Android process video files. Many text messaging apps — Google’s Hangouts app was specifically mentioned — automatically process that video so it’s ready for viewing as soon as you open the message, and so the attack theoretically could happen without you even knowing it. Google is saying that StageFright 1.0 is fixed. If I talk about my smartphone which is Motorola G, it got an update in which StageFright 1.0 patch is also there to fix it.

1. Try to not download mp3 or mp4 from your web-browsers.
2. Avoid public networks.
3. Secure your wi-fi connection with strong passwords.
4. Pay attention that where and what you are browsing

OS which have fixed StageFright 2.0

Blackphone 2, is a smartphone in which phone is encrypted for tightening the security. The company named it Silent OS which is also made from Android open source.

Cyanogenmod OS have patched for StageFright 2.0

I am surprised what Google is doing, is Google seriously doing something to secure their OS like IPhone. iOS is much more secure than Android. iOS released updates in timely fashion to make it secure and for better performance and keeping eye on their store. I read the news 10-20 days ago that a Chinese app in iOS was trying to do getting information. Apple quickly blocked that app from their store. This is called secure environment with quick action.

Wrap Up

Although android device covered more than 83% market globally but if security issues will go on continuously people will lose their interest in android device. Billions of android devices are at risk. Privacy is also at risk. StageFright attacker can get access to your android device at root level and can do anything. Let’s see what will happen in coming months. Hoping better future for android device in terms of security.

Angular JS is an open source java-script MVC framework developed by Misco Hevery/Adam Abrons  and maintained by Google and individual  developers Community.

It is being described by Angular Team as the “Structural framework for dynamic web applications”. Its main motive is to make the development and testing of Single Page Applications(SPA) easier and effective by providing a client side MVC architecture.

It basically extends and adapt HTML vocabulary with some additional declarations that are useful for web applications. With the concept of Two way data binding using scope it facilitates the automatic synchronization of views and models.

The design goals of Angular JS includes the following points :

1. To decouple the Application logic with the DOM manipulation.
2. To decouple the server side of the application with the client side. It makes the development of both run in parallel.
3. To provide a complete package starting from designing the UI through writing business logic, to testing.

Lets see the Architectural Pattern Diagram which is self explaining :

Just a simple example how to start with Angular JS

<!DOCTYPE html>

<html lang=”en”>
<head>
<script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js”></script>
</head>
<body ng-app=”myapp”>
<div ng-controller=”HelloController” >
<h2>Hello {{hello}} !</h2>
</div>
</body>
<script>
     angular.module(“myapp”, [])
      .controller(“HelloController”, function($scope) {
       $scope.hello = “World, AngularJS”;
    } );
</script>

Example Explained :

1. Here ng-app is a built-in directive of Angular JS which is needed to be defined to auto bootstrap the angular js application.
And ng-app contains the name of our module which we created in our JS code.
2. After that ng-controller attribute is used which tells Angular JS that which controller to use with this view.
3. Also you can see the {{hello}} text. This is a part of AngularJS’s template system which tells Angular to write the “model” value named hello   (given by  $scope.hello = “World, AngularJS”;) to the HTML at this location.
4. $scope is the  an object that refers to the application model. It holds the data to display in the view.
5. Its better to place HTML and JS code on different files to make MVC effective.
