Create your own LAN-Connect two computers
Why is it needed??
If we connect two computers, it forms a network. The main advantage of a network is "resource sharing".
We can share files and folders.
We can share printers.
We can play LAN games.
Here are the steps to connect two windows XP computers.
Things You Will Need:
1. A Crossover cabe – This is a Cat5 Ethernet Cable that the wires have been switched around to allow two computers to talk to each other.
2. Ethernet adapter or in simple terms the port on the back of your pc where you are going to insert this cable.
Steps:
1. Connect the two computers with the crossover cable.
2. Set the IP address on both computers. Goto Start > Control Panel > Network Connections ( Choose switch to classic view if you cannot see network connections ).
3. Look for your Local Area Connection ethernet adapter, right click and choose properties.
4. Select Internet Protocol TCP/IP and choose properties.
5. Set the IP as 192.168.1.1 and the subnet mask of 255.255.255.0 on the first computer and 192.168.1.2 on the second with same subnet mask.
6. click OK and OK/Close again.
NOTE: To share your files, right click on any folder or drive and choose sharing to make them shared.
This can also be done with printers to be able to print from one computer while the printer is connected to the other.
If you are using Windows 7 : The steps are similar, you can find your Local Area Connection in Network and sharing center.
All about IP addresses
Lets have a glance at the basics of IP..
What is an IP address?
If a post man wants to deliver a letter to you, first he needs to know the address of your home. In the same way Computers on the Internet need to find one another in order to communicate. Each computer therefore has a unique identifying number known as an IP address.
Simply.. Every system connected to internet must have a unique address. This address is called IP address.
Every URL (say, “www.google.com”) has its own numbered Internet Protocol or IP address.
An IP address looks something like this:74.125.19.147
An IP address is a series of numbers that tells us where a particular device is on the Internet network.
Public IP address
A public IP address is assigned to every computer that connects to the Internet where each IP is unique. Hence there cannot exist two computers with the same public IP address all over the Internet. This addressing scheme makes it possible for the computers to “find each other” online and exchange information. User has no control over the IP address (public) that is assigned to the computer. The public IP address is assigned to the computer by the Internet Service Provider as soon as the computer is connected to the Internet gateway.
Public IP addresses can be divided into two types.
They are STATIC and DYNAMIC..
What is static IP?
A static IP address does not change and is used primarily for hosting webpages or services on the Internet.
Disadvantages of static configuration
This requires manual configuration of each and every computer.
Every time care must be taken that no two systems should have same IP.
This manual configuration has many problems when number of systems increase.
Dynamic IP
On the other hand a dynamic public IP address is chosen from a pool of available addresses and changes each time one connects to the Internet. Most Internet users will only have a dynamic IP assigned to their computer which goes off when the computer is disconnected from the Internet. Thus when it is re-connected it gets a new IP.
To do this Dynamic Host Configuration Protocol (DHCP) was developed.
A DHCP server is a software program that assigns IP addresses to computer dynamically.
Advantages
Administrators of large networks save hundreds of hours per year over manual configuration of computers.
No IP address conflict.
Users need not know about manual configuration.
Private IP address
An IP address is considered private if the IP number falls within one of the IP address ranges reserved for private networks such as a Local Area Network (LAN). The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private networks (local networks):
10.0.0.0 – 10.255.255.255 (Total Addresses: 16,777,216)
172.16.0.0 – 172.31.255.255 (Total Addresses: 1,048,576)
192.168.0.0 – 192.168.255.255 (Total Addresses: 65,536)
How to find your Private IP?
go to start->open RUN->type cmd. Then command prompt will be opened->type the command "ipconfig" without brackets.
The number that you see against “IPV4 Address:” is your private IP.
How to find your public IP?
You can check your public IP address by visiting www.whatismyip.com

Windows-Passwords
We can hack windows passwords using different methods.
Before going to hack windows passwords,we must learn about the internal mechanism that windows follows.
In windows,passwords are stored at C:\windows\system32\config\SAM.
But, that file is read only and is used by the Operating System.
So a normal user cannot access it,rename it or change it in anyway while using windows.
Because the moment windows operating system starts, the SAM file becomes inaccessible.
What is SAM?
The Security Accounts Manager is a database in the windows operating systems that contains usernames and passwords.
When a new user account is created with a password, it gets stored in the SAM file. These passwords are contained in the SAM in the hexadecimal format called HASHES.
when a user attempts to login,the username and the associated password will be checked with the entries of the SAM file.
If any entry in the SAM file matches with the entered login details,the user will be logged in. Otherwise it returns an error message requesting the user to enter the login details again.
Types of password attacks:
Dictionary attack:
In this technique, some passwords will be written in a separate file called dictionary. This file contains common passwords used by the people. Using this file,we try to crack the password.
This is very fast but success rate is poor.
Brute Force Attack:
In this method we use all possible permutations by a set of character sets like 0-9,A-Z,a-z.
Advantage of this method is, the success rate is high.
Hybrid Attack:
We use the combination of the above two methods or any other.
Windows passwords can be hacked using the following tools.
1.Ophcrack live CD
2.ERD commander
3.Cain n Abel
4.John the ripper etc.
How to hack windows password using Cain n Abel
Cain n Abel works efficiently with bruteforce attack.
You should disable your antivirus/firewall before installing and working with Cain n Abel. Otherwise it will not work.
As Brute Force Attack: technique takes more time to complete, select this technique if you are thinking that the victim has small password containing same type of characters or two types of characters.i.e only numeric or only lower alphabets or only loweralphabets-numeric and the password length must be less than 7 characters.
Things required:
Cain n Abel.
you can download it from here.
Procedure:
1)Open "Cain n Abel"
2)click the tab "cracker".
Now you will see some "sub-categories" in left panel.
3)Select "LM&NTLM" hashes from left panel
4)click "+" button.
5)Check "import hashes from local system" and then click "Next". You will see all active accounts.
6)right click on any user or admin you want to hack and select "bruteforce"->"NTLM Hashes"
7)you will see a window. Here click on start.
8)After completing,it shows the exact password.
What is phishing?
By srinivas Postado Monday, 19 September 2011
What is phishing?
Phishing is an attempt by the sender to have the receiver of the email to release their personal information i.e the attacker lures the victims to give some confidential information.
Why phishing?
There are many password cracking tools that are coming and going into/from the market. But phishing is the most effecient method to steal confidential information like,
passwords
Credit card numbers
Bank account numbers
How phishing works?
It works just like normal fishing.
A fisherman generally throws a bait into the water to lure the fish. Then a fish comes to take the food feeling that it is legitimate. When it bites the bait,it will be caught by the hook.Now the fisherman pulls out the fish.
In the same way, the hacker sends a fake login page to the victim. The victim thinks that it is a legitimate one and enters his confidential information.Now the data will be with the hacker.
How to protect ourselves from phishing?
Don’t use links
Be suspicious of any e-mail with urgent requests
using secured websites
Using efficient browsers
Using Antivirus or internet security softwares.
How to hack gmail using phishing.
Things required:
1)gmail.html (fake login page)
2)mail.php (to capture the login details)
3)log.txt (to store the captured details)
You can download them from here.
Procedure:
step1: create an account in any free web hosting site like
www.110mb.com
www. t35.com
www. ripway.com
www. my3gb.com
step2: Now upload all the three files you have downloaded.(I have taken www.my3gb.com)
step 3: Give the link of the fake page to your victim.
eg: www.yoursitename.my3gb.com/gmail.html
step 4:when he clicks the link, it opens a fake gmail page where he enters his login details. When he clicks sign in button,his login details will be stored in log.txt file.
Demonstration:
Here i have uploaded my scripts on to www.my3gb.com
and i clicked the gmail.html link.
A fake page was opened where i entered my login details.
Now my login details were captured by the php script and stored in log.txt file as shown in the figure below.
Have you ever written a love letter to your girl friend/boy friend in your notepad and caught by your father??
If yes, you will never be caught again.. because windows provides an excellent feature called Alternate Data Streaming.
What is Alternate Data Streaming?
It is a feature in windows to Hide Files into existing files without affecting their actual functionality or size.
Simply we can hide data in hidden files which are linked to a normal visible file.
Procedure:
Here i will show you how to hide a text file behind a text file.
1)first open command prompt.
you can open it by following these steps.
start->run->type cmd.
now a command prompt will be opened.
2)here type the following command
C:\notepad confidential.txt
It opens a notepad. Type something and save it on your desktop.
Now type the following command
C:\notepad confidential.txt:hack.txt
It opens a notepad where you have to write your text(love letter) that is to be hidden. and click save.
thats it.
The "hack.txt" file is hidden behind your "confidential.txt"
If any one opens your confidential.txt, it doesnt show your hack.txt even though it is behind that file.
If you want to see your hidden file, again type the following command
C:\notepad confidential.txt:hack.txt
It opens your hidden file.
How to identify fake log-in pages to avoid phishing
Phishing attacks are very simple to avoid.
When you are asked to put your confidential data in any website or login pages, first check the URL.
If the URL is different from your original URL, then it is a fake page.
say.. we have gmail, in this case the URL should be "mail.google.com" or "gmail.com" like this.
Anything else is fake.
We can also identify fake login pages by observing the source code of the page.
In the case of gmail fake login page, do the following steps.
1) right click on the page
2) click on "view page source"
3) Now the source code of the page will be opened.
4) Now search for the word "action"
This can be done by pressing "ctrl+f". It opens a search box. Now enter the word "action" into the box and press enter.
If You see "something.php" next to the word "action" then it is a fake page. otherwise it will be original a one.
Block websites without using any software
We can block websites in windows by modifying HOSTS file.
What is HOSTS file?
One of the lesser known, but important files included with Windows is the hosts file.
It's a simple text file without any file extension that was designed to map or override IP addresses before accessing a domain name server.
i.e when you enter a domain name (eg:www.google.com), your browser searches for the IP address of www.google.com in your HOSTS file before searching it in the DNS server.
Procedure:
step 1)open your notepad with admin rights as shown below.
step2)now goto file and click on "open" and then navigate to C:\windows\system32\drivers\etc
step3)Now change your extension to "all files" in the notepad.
you will see HOSTS file and open it.
It will look like
step4)add the following lines in the HOSTS file as shown in the figure.
127.0.0.1 www.google.com
127.0.0.1 google.com
step5)save it. and open your browser. Now type www.google.com
It will not be opened.
An Introduction to malwares
Malware is a short form for malicious software. It consists of programming code designed to disrupt or deny operation, gather information that leads to loss of privacy, gain unauthorized access to system resources etc. Simply it is a software program that does many malicious things.
These Malwares include virus,worm,trojan,RAT,keyloggers etc.
Virus:
A computer virus is a computer program that can replicate itself and spread from one computer to another. A true virus can spread from one computer to another when its host is taken to the target computer. For instance because a user carried it on a removable medium such as a USB drive.
Worm:
A computer worm is a self-replicating malware, which uses a computer network to send copies of itself to other computers on the network. It doesnt need any user intervention.A worm does not need to attach itself to an existing program. Worms always cause at least some harm to the network, even if only by consuming bandwidth.
Trojan Horse:
Trojan are used to get remote access to a target computer system. Once a Trojan has been installed on a target computer system,we may have access to the computer remotely and perform various operations, limited by user privileges on the target computer system and the design of the Trojan.
RAT:
A Remote Administration Tool (a RAT) is a piece of software that allows an operator to control a system as if he has physical access to that system. The operator controls the RAT through a network connection. It is very similar to trojans.
Key loggers:
keyloggers are softwares which record every key stroke pressed by the user of a computer. They can perform many other things like taking screenshots,monitoring the system etc.
Block unwanted emails in Gmail
Sometimes you may not like to receive emails from some particular email IDs.
Gmail is providing filters to filter those type of mails. Other email services like yahoo,hotmail are also providing this filtering service.

How to identify fake log-in pages to avoid phishing
Phishing attacks are very simple to avoid.
When you are asked to put your confidential data in any website or login pages, first check the URL.
If the URL is different from your original URL, then it is a fake page.
say.. we have gmail, in this case the URL should be "mail.google.com" or "gmail.com" like this.
Anything else is fake.
We can also identify fake login pages by observing the source code of the page.
In the case of gmail fake login page, do the following steps.
1) right click on the page
2) click on "view page source"
3) Now the source code of the page will be opened.
4) Now search for the word "action"
This can be done by pressing "ctrl+f". It opens a search box. Now enter the word "action" into the box and press enter.
If You see "something.php" next to the word "action" then it is a fake page. otherwise it will be original a one.
We can block websites in windows by modifying HOSTS file.
What is HOSTS file?
One of the lesser known, but important files included with Windows is the hosts file.
It's a simple text file without any file extension that was designed to map or override IP addresses before accessing a domain name server.
i.e when you enter a domain name (eg:www.google.com), your browser searches for the IP address of www.google.com in your HOSTS file before searching it in the DNS server.
Procedure:
step 1)open your notepad with admin rights as shown below.
step2)now goto file and click on "open" and then navigate to C:\windows\system32\drivers\etc
step3)Now change your extension to "all files" in the notepad.
you will see HOSTS file and open it.
It will look like
step4)add the following lines in the HOSTS file as shown in the figure.
127.0.0.1 www.google.com
127.0.0.1 google.com
step5)save it. and open your browser. Now type www.google.com
It will not be opened.
An Introduction to malwares
Malware is a short form for malicious software. It consists of programming code designed to disrupt or deny operation, gather information that leads to loss of privacy, gain unauthorized access to system resources etc. Simply it is a software program that does many malicious things.
These Malwares include virus,worm,trojan,RAT,keyloggers etc.
Virus:
A computer virus is a computer program that can replicate itself and spread from one computer to another. A true virus can spread from one computer to another when its host is taken to the target computer. For instance because a user carried it on a removable medium such as a USB drive.
Worm:
A computer worm is a self-replicating malware, which uses a computer network to send copies of itself to other computers on the network. It doesnt need any user intervention.A worm does not need to attach itself to an existing program. Worms always cause at least some harm to the network, even if only by consuming bandwidth.
Trojan Horse:
Trojan are used to get remote access to a target computer system. Once a Trojan has been installed on a target computer system,we may have access to the computer remotely and perform various operations, limited by user privileges on the target computer system and the design of the Trojan.
RAT:
A Remote Administration Tool (a RAT) is a piece of software that allows an operator to control a system as if he has physical access to that system. The operator controls the RAT through a network connection. It is very similar to trojans.
Key loggers:
keyloggers are softwares which record every key stroke pressed by the user of a computer. They can perform many other things like taking screenshots,monitoring the system etc.

Android-an open platform for mobile development
ANDROID:
Android is a software stack for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language. It is a Linux based operating system developed by Google supports cellular based communication.
Eg.: gsm,cdma
It is unique because Google is actively developing this platform (API) and is downloaded and is moulded according to us and can be used. The main purpose of this android operating system is we can mould this android os on our own device.
Why android?
1. Android can Run Multiple Apps at the Same Time
Starting with version 1.0, Android has been able to run multiple applications at the same time regardless of whether they are system apps or apps from the Android Marketplace. Android users benefit greatly from this discrepancy, as they can receive notifications, listens to music, or even record GPS data without keeping the application open.
2. Android Keeps Information Visible on Your Home Screen
One of the key features Android has is a customizable home screen keeps active widgets right at your fingertips, always accessible and always visible - without having to launch an application first.
3. Android Gives You Better Notifications
The other os has some trouble with notifications. Because they are restricted to pop-up notifications, they can only handle one at a time and because it lacks multitasking, applications must be open in order for them to make notifications. Android, on the other hand, has a convenient notification bar which displays an icon for every notification you have waiting. The notification bar can also be pulled downward to reveal more detail about each notification.
4. Android Lets You Change Your Settings Faster
Smart phones have been gaining more and more functionality over the past few years: Wi-Fi, GPS, 4G, Bluetooth, etc. While these are all great and necessary additions, they have very adverse affects on battery life. In attempts to counter poor battery life, users have taken to toggling system settings like turning on Wi-Fi or 3G on only when they are needed. Android lets you use widgets to manage your settings directly from your home screen - and for those lesser-used settings that might not have dedicated widgets, you can also create shortcuts on your home screen to take you directly to the setting you want to change.
