Android for beginners-Part 1

Jelly Bean
This article marks for an inception of something new, something cool, something to brag about and something that makes you feel more tech savvy. Android started to come to the surface in 2008. Since then, billions of gadgets from thousands of companies have embedded it in their roots. And naturally, more developers, whether from a corporation or independent and trying their hands on it. So, we now begin

What is Android?

An operating system that is derived from java. Java is object-oriented, such that it’s workings mimic the real world objects. Programs have been made easy to comprehend, to create and to recreate due to this. Hence, derivatively, Android is easy to learn but difficult to master language whose only limitation, is your imagination and your tenacity. Okay now, enough with the emotional-motivational part.

A java program is needed to be compiled into a DEX file to be executed as an android one. I imagine that if you are reading this. you might understand how programming works exactly. You write thecode-> compile the code-> execute the code.

DEX

Dalvik executable. This executable file is mapped for efficient storage and memory mapped execution. Its history is not you should concern yourself with. This topic is about the future.

Below are the things you require before you go on to fondle with the android.

  • An IDE (Integrated Development Environment): This environment gives you developing tools, debugging tools(error removal) and an emulator to test your projects on. Use Android Studio, a free development IDE. Download using the given red colored link.
  • A JDK(Java development kit): Download and install it before downloading and installing the Android Studio. As I say, “Can’t do anything without a good java!”
  • A system with a minimum of 4gigs of RAM.
  • Windows 7/8/10. I am learning it on windows. So you get to do the same too.
  • An android powered tablet or phone with a minimum of Android 4.1 Jellybean.
  • Tenacity to learn

Accumulate these things and you are good to go. By the time we are done, you will be cooking android apps like instant noodles.

 

Search engine for hackers, and it lists every device on the net

Meet Censys, a Shodan like search engine for hackers.

censys

Last month the security consultants at the SEC realized that the work-shy manufacturers of IoT(Internet Of Things) using the same old set of hardcoded cryptographic keys leaving over 3 million of IoT devices vulnerable to mass hijacking. But how did they found out the exact number??

Easy! Censys told them. A search engine that ransacks the net for vulnerable devices.

It knows everything and sees everything

Censys is designed for one purpose, to scan for the poor bastards who got logged on to the net without much thought about unauthorized access to them. Clarification, the poor bastards are the devices. In this aspect Censys is a lot like shodan .

However, the methodology used by Censys is much more complex. All this to make internet a safer place.

Released for free in October by the researchers at the University of Michigan, is powered by google, world’s biggest search engine.

As a part of an open source project, census was created to keep track of every data on the internet. And then create a database out of it. the goal of this is to help companies to unearth their vulnerabilities on the net.

Modus Operandi of Censys.

This search engine for hackers does daily scans of Ipv4 address space. By this it collects the information of hosts and websites. Two tools are plied for this purpose

  1. Zmap : Open Source network Scanner
  2. ZGrab: Application layer scanner

Then databases are maintained after the collection of data(DUH!). This gives the information about how websites are configured.

Zmap’s job is to scan over 4 billion IP addresses every day. What’s more is this helps determining to whether fix the machines right away or not. Whether the prowling eyes of hackers is upon the device already?

Flaws caused by IT administrator can’t hide either.

  So what do ya thing about this? Should this exist? And if it has to, how vulnerable are you?

Post your comments and enlighten our asses.
