Connect your Mac to the Windows computer using a standard Ethernet cable. If your Mac doesn’t have an Ethernet port, try using a USB-to-Ethernet adapter. Connecting the two computers creates a small local network that consists of just the two computers. On the Windows computer, turn on file sharing.
Wireless networks are accessible to anyone within the router’s transmission radius. This makes them vulnerable to attacks. Hotspots are available in public places such as airports, restaurants, parks, etc.
In this tutorial, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks.
Topics covered in this tutorial![]() What is a wireless network?
A wireless network is a network that uses radio waves to link computers and other devices together. The implementation is done at the Layer 1 (physical layer) of the OSI model.
How to access a wireless network?
You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point. Most devices (if the wireless network option is turned on) will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access.
Wireless Network Authentication
Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected. Let’s look at some of the most commonly used authentication techniques.
WEP
WEP is the acronym for Wired Equivalent Privacy. It was developed for IEEE 802.11 WLAN standards. Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping.
WEP Authentication
Open System Authentication (OSA) – this methods grants access to station authentication requested based on the configured access policy.
Shared Key Authentication (SKA) – This method sends to an encrypted challenge to the station requesting access. The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted.
WEP Weakness
WEP has significant design flaws and vulnerabilities.
Because of these security flaws, WEP has been deprecated in favor of WPA
WPA
WPA is the acronym for Wi-Fi Protected Access. It is a security protocol developed by the Wi-Fi Alliance in response to the weaknesses found in WEP. It is used to encrypt data on 802.11 WLANs. It uses higher Initial Values 48 bits instead of the 24 bits that WEP uses. It uses temporal keys to encrypt packets.

How to Crack Wireless Networks

Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. WEP cracking refers to exploits on networks that use WEP to implement security controls. There are basically two types of cracks namely;
WEP Cracking Tools
WPA Cracking
WPA uses a 256 pre-shared key or passphrase for authentications. Short passphrases are vulnerable to dictionary attacks and other attacks that can be used to crack passwords. The following tools can be used to crack WPA keys.
General Attack types
Cracking Wireless network WEP/WPA keys
It is possible to crack the WEP/WPA keys used to gain access to a wireless network. Doing so requires software and hardware resources, and patience. The success of such attacks can also depend on how active and inactive the users of the target network are.
We will provide you with basic information that can help you get started. Backtrack is a Linux-based security operating system. It is developed on top of Ubuntu. Backtrack comes with a number of security tools. Backtrack can be used to gather information, assess vulnerabilities and perform exploits among other things.
Some of the popular tools that backtrack has includes;
Cracking wireless network keys requires patience and resources mentioned above. At a minimum, you will need the following tools
A wireless network adapter with the capability to inject packets (Hardware)
How to Secure wireless networks
In minimizing wireless network attacks; an organization can adopt the following policies
Hacking Activity: Crack Wireless Password
In this practical scenario, we are going touse Cain and Abel to decode the stored wireless network passwords in Windows. We will also provide useful information that can be used to crack the WEP and WPA keys of wireless networks.

Summary
The question “how to hack a computer” is probably the one that is most frequently asked by many Internet users and hacking enthusiasts. So, in order to address some of the common questions and doubts on the subject, I have decided to write down this article. If you are looking for information on possible ways to hack a computer, this post can surely help you out.
What Computer Hacking Really Means?
Computer hacking is a vast subject and it has several different meanings. For example, when someone superficially asks how to hack a computer, it can simply mean how to break the password of a local or remote computer so as to gain access to it. However, hacking is not only that which involves breaking into a computer. If you go deeper, computer hacking can also involve things like techniques to bypass the authentication of a system, hack Internet users, computer databases, software programs and so on.
So, to define in simple words computer hacking is a means of exploiting the weakness in a computer system or network in order to gain unauthorized access to its data or take advantage of it.
How Can I Begin to Hack?
To hack a computer, you need to do know how computers actually work and learn some basic concepts on the subject. If you are serious and passionate about it, you can take up an ethical hacking course that will help you master the skills. You can pick up a book that will teach you the concepts of computer hacking right from the basics. If you are a beginner, we recommend the book “Hacking Secrets Exposed” which is an excellent source of information to start off.
What Skills Do I Need to Hack a computer?Hack Computers On Same Network Mac Pro
Even though there exists a lot of ready-to-use tools and programs on the Internet, you should possess at least a fair amount of computer knowledge to make use of them. Things like basics of operating system, computer networks and their protocols, firewalls and knowledge of how each of these work seems necessary. If you want to take it up as a profession and want to become an ethical hacker or penetration tester you will have to go a few steps further and consider learning operating systems like Unix/Linux and also programming languages like C, PHP, JavaScript, SQL etc.
If you are completely new to hacking and only have a basic knowledge of computer, you can refer freely available resources on the Internet to develop your skills. However, if you need an easy to follow guide with all the necessary resources at one place and don’t mind spending a few dollars, go for the book Hacking Secrets Exposed which is a perfect source of learning for beginners and intermediate readers.
Is Computer Hacking Legal?Mac Network Settings
In most cases hacking a computer without the permission of its owner is considered illegal. Mac computer got hacked photos. However, there are many ethical hackers who are hired by large companies and government organizations with special permissions to break into a computer in cases such as catching a cyber criminal or terror group. Sometimes penetration testers are given prior permission to hack computers so that possible vulnerabilities could be found and patched up before another hacker exploits it. In such cases it is completely legal to hack a computer.
