Wireless Hacking

Wireless Hacking

Hello Friends, Today we are going to study "Wireless Hacking". Wireless networks are all around , from home to corporate server farms. They make our lives by avoiding physical connectivity to networks via cables while providing guaranteed consistent network connectivity of devices. It is an advantage with a certain danger attached to it . Wireless network are prone to hacking attacks. We will examine a couple of strategies to secure wireless networks to accomplish satisfactory security.

How do Wireless Network Work ?

Before we discuss wireless network security and weakness, we must understand the fundamental radio transmission and the IEEE 820.11 protocol, regularly known as the WLAN protocol. This protocol connects two or more devices within the short range, Using radio signals. to set up a wireless network, you require a wireless access point and a wireless network card for every device to be connected. The access point is also referred as a Hotspot. It consists of a radio transmitter which is used for transmitting and receiving signals, additionally it also contains hardware which converts data signals to radio signals & vice versa.

we can access a wireless network using wireless network enabled device such as a laptop, tablet, smartphones etc. within the transmission range of a wireless point. most of the device have the wireless network option enabled by default.

you can connect to any wireless network if it is not password protected. if it is password protected then you will need the password to gain access.

Wireless network Authentication 

As the wireless network network is open to every body who has a wireless network enabled gadget, most network are now configured with some kind of encryption and authentication mechanisms.

Let's take a look at some of the commonly used wireless authentication techniques.

WEP

WEP is the acronym for wired equivalent privacy. It was developed for IEEE 802.11 WLAN standards. Its objective was to provide data protection similar or equivalent to that provided by wired networks. WEP encrypts the data, When transmitted over the networks to keep it safe.

WEP Weakness

WEP has significant design flaws and vulnerabilities 

• WEP is based on passwords which makes it vulnerable to dictionary based attacks.
• WEP uses R encryption algorithm to create stream ciphers. The stream Cipher input is made of an initial value (iv) and a secret key. The length of the initial value (iv) is 24 bits long while the secret key can either be 40 bits or 140 bits long. The total length of both the initial value and secret can either be 64 bits or 128 bits long. The lower possible value of the secret key makes it easy to crack it.
• Weak initial values combination don't encrypt adequately.
• Initial values can be reused.

WPA

WPA stands for WI-FI Procted access. It is A security Protocol developed through The WI-FI alliance in response to the weakness found in WEP. It is used to encrypt data on 802.11 WLAN's. It uses higher initial values 48 bits as an alternative to the 24 bits that WEP uses. It uses temporary Keys to encrypt packets.

WPA Weakness

• The collision avoidance implementation can be broken.
• It is vulnerable to DoS attacks.
• Pre-shared keys Use passphrases. Weak passphrases are vulnerable to dictinary based attacks.

Finding The location Of a Server

Finding The location Of a Server

Hello Friends, Today i am going to Show to How to Find the location of a Server. This is very Important step in hacking a Server. In a Case you got caught by Cyber Police you can get rid out of the case from the loopholes in Cyber Laws of that country. It will Only happen when you know the Cyber law of that Country this is only possible when you know the location of the server.

  

Pre-requisite

• A Computer installed with OS
• Internet Connection 

What is a Web server ?

A web server is a computer system that processes requests via HTTP, the basic network protocol used to distribute information on the World Wide Web. The term can refer to the entire system, or specifically to the software that accepts and supervises the HTTP requests.

The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). Pages delivered are most frequently HTML documents, which may include images, style sheets and scripts in addition to text content.

Steps to Find The Location Of a Server

1- Open Your Web Browser.

2- Search For "www.iplocation.org".

3- "iplocation.org" Looks like This

4- Give the Target Domain or IP Address.

5- Click on IP lookup.

6- It will show you Result Like This.

You can See that It shows the IP Address Of the Target & Country, Region, City .

How to Hide IP Address in Android 

Hello Friends, Today I am Going to show you How to Hide IP Address in Android . We should Hide Our IP address for some Security reasons like :-

• For Hiding Geographical Location.
• To Prevent Web Tracking.
• To avoid Leaving a Digital Footprint.
• To Bypass Blocked Sites on their IP Address.

[NOTE]

This Tutorials Is only for Educational Purpose. I will not Responsible any Damage done to your Android Handset

Introduction

Internet has Become so common these days that most of the people take it for granted. While everyone spends hours on internet, only a few online seems to care about their security When they are Online. Cyber Security has become one of the burning issues in this decade and your security is always in your hand. The small measure we take towards secure browsing will have a huge impact. using strong password, Hiding your IP address are some of the security measure you can follow, while the first one is self explanatory in this article I will show you how you can hide your IP address in your PC and Smartphone 

What Is IP address ?

An Internet Protocol address (IP address) is a numerical label assigned to each device (Computer, Printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."

Why you should Hide IP Address ?

You may have your own reasons for hiding your IP Address, but here are a few technical reasons why people hide their public IP Address.

Hiding your IP Address is a good step in Protecting Yourself Online. I don't Want you to think it's Useless, But it's Certainly not the definitive measure that keeps your Online status Anonymous or Protected. 

We should Hide Our IP address for some Security reasons like :-

Basics OF Networking

Basics OF Networking 

What is Network ?

A computer Network or data Network is a Telecommunications Work which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.

• Interconnection of two or more devices is called as a Network.
• The Communication between two or more interconnected devices is called networking.
• An internetwork is a connection of two or more network.
• Internetworking means communication between different networks.

Types of Network ?

• LAN-  Local Area Networks are used to connect networking devices that are in a very close geographic area such as a floor of a building, a building itself or with in a campus.
• MAN- Metropolitan Area Network are used to connect networking devices that may span around the entire city.
• WAN- Wide area networks which connects two or more LANs present at different geographical locations.

LAN Network

Man Network

WAN Network

Basic Requirements to Form a Network.

• NIC ( Network Interface Card ) also called as LAN card.
• Media 
• Networking device like ( Hub,Switch,Router etc. )
• Protocols 
• Logical Address ( IP Address )

NIC(Network Interface Card)

• NIC is the interface between the computer and the network.
• It is also known as the LAN card or Ethernet Card.
• Ethernet Card have a unique 48 bit address called as MAC (Media access Control) Address. MAC Address is also called as physical address or hardware address. The 48bit MAC address is represented as 12 Hexa-decimal digits. Example :0 0 1 6.D 3 F C. 6 0 3 F
• Network card are available in Different Speed.
• Ethernet ( 10 Mbps)
• Fast Ethernet ( 100 Mbps)
• Gigabit Ethernet (1000 Mbps)

Topology

Topology is a physical layout of the system connected in a network.

Different types of Topology are:

• Bus
• Ring
• Mesh
• Star

Bus Topology

• In bus topology all devices are connected to a single cable or backbone.
• It support half duplex communication.
• A break at any point along the backbone will result in total network Failure.

Ex:

Ring Topology

• In Ring topology each computer or device is connected to its neighbor forming a Loop.
• Failure of a single Device or a break anywhere in the cable cause the full network to stop communicating.

                                                                     Ex:

Mesh Topology

• In mesh topology each device is directly connected to all other device.
• The disadvantage is the number of NIC's required on each device and the complex cabling.

Ex:

Start Topology

• The most commonly used topology.
• It consist of one centralized device which can be either a switch or a hub.
• The device connect to the various ports on the centralized devices.

Ex:

Networking Devices 

The various types of Networking Devices are:

• Hub
• Switch
• Router

Hub / Repeater

• It is not an Intelligent device.
• It works with bits.
• Uses broadcast for communication.
• Bandwidth is shared.
• Half-duplex communication.

Ex:

Switch

• It is an Intelligent Device.
• It maintains MAC address table ( Hardware address )
• Each port of the switch has fixed bandwidth.
• It works with flooding and Unicast
• Supports full duplex communication. 

Ex:

Router

• It is an Intelligent device.
• It works with logical addressing (i.e IP, IPX, Apple Talk)
• It work with Fixed bandwidth.
