Secure Wi-Fi

1. Install a Firewall A firewall helps protect your PC by preventing unauthorized users from gaining access to your computer through the Internet or a network. It acts as a barrier that checks any information coming from the Internet or a network, and then either blocks the information or allows it to pass through to your computer.

2. Change the Administrative Password on your Wireless Routers Each manufacturer ships their wireless routers with a default password for easy initial access. These passwords are easy to find on vendor support sites, and should therefore be changed immediately.

3. Change the Default SSID Name and Turn Off SSID Broadcasting This will require your wireless client computers to manually enter the name of your SSID (Service Set Identifier) before they can connect to your network, greatly minimizing the damage from the casual user whose laptop is configured to connect to any available SSID broadcast it finds. You should also change the SSID name from the factory default, since these are just as well-known as the default passwords. NOTE: Even though the SSID is disabled the SSID is included in the data packets that are transmitted and is easy to discover.

4. Disable DHCP For a SOHO network with only a few computers, consider disabling DHCP (Dynamic Host Configuration Protocol) on your router and assigning IP addresses to your client computers manually. On newer wireless routers, you can even restrict access to the router to specific MAC addresses.


5. Replace WEP with WPA WEP (Wired Equivalent Privacy) is a security protocol that was designed to provide a wireless computer network with a level of security and privacy comparable to what is usually expected of a wired computer network. WEP seeks to establish security by encrypting data transmitted over the wireless computer network. Data encryption protects the vulnerable wireless link between clients and access points. Once this measure has been taken, other typical wire computer network security mechanisms such as password protection, end-to-end encryption, virtual private networks (VPN's), and authentication can be put in place to ensure privacy. Unfortunately, WEP is a very weak form of security that uses common 60 or 108 bit key shared among all of the devices on the network to encrypt the wireless data. Hackers can access tools freely available on the Internet that can crack a WEP key in as little as 15 minutes. Once the WEP key is cracked, the network traffic instantly turns into clear text – making it easy for the hacker to treat the network like any open network. WPA (Wi-Fi Protected Access) is a powerful, standards-based, interoperable security technology for wireless computer networks. It provides strong data protection by using 128-bit encryption keys and dynamic session keys to ensure a wireless computer network's privacy and security. Many cryptographers are confident that WPA addresses all the known attacks on WEP. It also adds strong user authentication, which was absent in WEP.

Introduction to CSS

CSS is the acronym for: ‘Cascading Style Sheets’. CSS is the sister language to HTML that allows you to style your web pages. An example of a style change would be to make words bold. In standard HTML you would use the <b> tag like so:

<b>make me bold</b>

This works fine and there is nothing wrong with it per se, except that now if you wanted to, say, change all your text that you initially made bold to underlined, you would have to go to every spot in every page and change the tag.
Another disadvantage can be found in this example: say you wanted to make the above text bold, make the font style Verdana and change its color to red you would need a lot of code wrapped around the text:

<font color="#FF0000" face="Verdana, Arial, Helvetica, sans-serif">
<b>This is text</b></font>

This is verbose (wordy) and contributes to making your HTML messy. With CSS you can create a custom style elsewhere and set all its properties, give it a unique name and then ‘tag’ your HTML to apply these stylistic properties:

<p class="myNewStyle">My CSS styled text</p>

And in between the <head></head> tags at the top of your web page you would insert this CSS code that defines the style we just applied:

<style type="text/css">
<!--
 .myNewStyle {
  font-family: Verdana, Arial, Helvetica, sans-serif;
  font-weight: bold;
  color: #FF0000;
 }
-->
</style>

In the above example we include the style sheet code inline, or in other words, in the page. This is fine for smaller projects or in situations where the styles you’re defining will only be used in a single page.
There are many times though when you will be applying your css styles to many pages and it’s a hassle to have to copy and paste the CSS code into each page. Besides the fact that you will be cluttering up each page with duplicate CSS code, you also find yourself having to edit each of these pages … if you want to make a style change.
The solution: like with JavaScript, you can define/create your CSS style in a separate file and then link it to the page you want to apply the code to:

<link href="myFirstStyleSheet.css" rel="stylesheet" type="text/css">

The above line of code links your external style sheet called ‘myFirstStyleSheet.css’ to the HTML document. You place this code in between the <head> </head> tags in your web page.
To create an external style sheet all you need to do is create a simple text document (on Windows you simply right-click and select new -> text document) and then change it from a file type .txt to .css. You can change the file type by just changing the file names extension. The file name’s extension on Windows tells the computer what kind of file it is and allows the computer to determine how to handle the file when, for example, you try to open it.
You probably guessed it; CSS files are just specially (specifically) formatted text files much in the same way that HTML pages are. There is nothing special or different about the file itself, rather it is the contents of the file that makes a CSS document a CSS document.
When working with an external CSS document there are a couple of points to remember:
1. You DON’T add these tags in the CSS document/page itself as you would if you embedded the CSS code in your HTML:

<style type="text/css"></style>

Since the link in your web page connecting the CSS page to your HTML page says that you are linking to a CSS page, you don’t need to declare that the code in the page is CSS. That is what the above tags do. Instead you would just add your CSS code directly to the page:

.myNewStyle {
 font-family: Verdana, Arial, Helvetica, sans-serif;
 font-weight: bold;
 color: #FF0000;
}
 
.my2ndNewStyle {
 font-family: Verdana, Arial, Helvetica, sans-serif;
 font-weight: bold;
 color: #FF0000;
}
 
.my3rdNewStyle {
 font-family: Verdana, Arial, Helvetica, sans-serif;
 font-weight: bold;
 font-size: 12pt;
 color: #FF0000;
 
}

In the above example I have created a series of CSS classes that can be applied to any HTML tag like so:

<p class="myNewStyle">My CSS styled text</p>

or

<h2 class="my3rdNewStyle">My CSS styled text</h2>

You will notice that in the above example I applied a CSS style to an <h2> tag. This tag sets the size of the text that it wraps to a size that is preset in the browser (ex: 10 pixels). When you apply a CSS class to it, the CSS code overrides the default size that you would normally get with an <h2> tag in favor of the size specified in the CSS class. So now you can see that CSS can override default HTML tag behavior!
In the above examples, I have CSS code where I define my CSS classes and then ‘apply’ them to various elements in the page. Another way to apply CSS is to globally redefine an HTML tag to look a certain way:

h1 { font-family: Garamond, "Times New Roman", serif; font-size: 200%; }

What this CSS code does is set the font style and size of all <h1> tags in one shot. Now you don’t have to apply a CSS class as we did before to any <h1> tag since they are automatically all affected by the CSS style rules.
Here is another example of where I give the whole page bigger margins:

body { margin-left: 15%; margin-right: 15%; }

As you can see, you can redefine any tag and change the way it looks! This can be very powerful:

div {
 background: rgb(204,204,255);
 padding: 0.5em;
 border: 1px solid #000000;
}

Set in the above code, any <div></div> tag will now have a background color of ‘rgb(204,204,255)’ and have a padding of 0.5em and a thin 1 pixel border that is solid black.
A few things to explain about the above:
Color in CSS can be expressed in a few ways:

1. In Hex -> for example: #000000 – this is black and this: #FF0000 is red.
2. In rgb -> rgb(204,204,255) is a light purple-blue color.
3. With named colors like: ‘red’ or ‘blue’

I typically use hex color since I am familiar with them or I just use named colors. So the last example can be rewritten like so:

div {
 background: green;
 padding: 0.5em;
 border: 1px solid #FF0000;
}

So instead of ‘rgb(204,204,255)’ , I just specified ‘green’.
By using RGB (RGB is the acronym for: ‘Red Green Blue’) and Hex color, you can really get the exact color you want easily when you know your codes. Luckily many programs (like Dreamweaver) provide easy to use color pickers for you so you don’t need to know the values for the code.
In this last example I will show you the ‘super cool’ CSS code that allows you to create link roll-over effects without images:

:link { color: rgb(0, 0, 153) } /* for unvisited links */
:visited { color: rgb(153, 0, 153) } /* for visited links */
:hover { color: rgb(0, 96, 255) } /* when mouse is over link */
:active { color: rgb(255, 0, 102) } /* when link is clicked */

The above CSS will cause your link to change color when someone hovers their mouse pointer over it, instant rollovers with no images! One important note with the above code is that it is important that the style declarations be in the right order: "link-visited-hover-active", otherwise it may break it in some browsers.
CSS is very powerful and allows you to do things that you can’t do with standard HTML. It is supported nicely now in all the modern browsers and is a must learn tool for web designers.
The above examples are just a small sample of what you can do with CSS, but it should be more than enough for you to start styling your pages nicely. Like with many technologies, CSS has a lot of capability that most people will not need to use often if at all. Don’t get caught in the trap of thinking that if there is some functionality/feature available, that you have to use it.

Create your own f@ke login page!!! | Create your own fake Page

This is an easier version from the “How to Hack Gmail, Yahoo, Hotmail, Orkut or Any Other”

This goes into more detail on how to create a fake page to login, and get redirected while it is sending a email of the password and username to your inbox. If you found this easy, then try out the post, “How to Hack Gmail, Yahoo, Hotmail, Orkut or Any Other”

Fake login page is a fake page which you can use to hack others username and password. Fake login page looks exactly like the original page and if someone login in your page using his original username and password, the username and password will be mailed to you
The process of Hacking anyone’s id using fake login pages is known as Phishing

Now let’s learn how to create your very own fake login page.
{1} Open www.jotform.com and Sign Up.
{2} then Login there with your newly registered account.
{3} now click on ‘ Create your first form’.
{4} Now delete all the pre-defined entries, just leave ‘First Name:’ (To delete entries, select the particular entry and then click on the cross sign.)
{5} Now Click on ‘First Name:’ (Exactly on First Name). Now the option to Edit the First Name is activated, type there “username:” (for Gmail) or YahooId: (for Yahoo)
{6} Now Click on ‘Power Tool’ Option (In right hand side…)
{7} Double click on ‘Password Box’. Now Click the newly form password entry to edit it. Rename it as ‘Password:’
{8} Now Click on ‘Properties’ Option (In right hand side…). These are the form properties.
{9} You can give any title to your form. This title is used to distinguish your forms. This Title cannot be seen by the victim.
{10} Now in Thank You URL you must put some link, like http://www.google.com or anything. Actually after entering username & password, user will get redirect to this url.(Don’t leave it blank…)
{11} Now Click on ‘Save’. After saving, click on ‘Source’ Option.
{12} Now you can see two Options, namely ‘Option1′ & ‘Option2′. Copy the full code of ‘Option2′.
{13} Now open Notepad text editor and write the following code their.
Paste the Option2 code here
{14} And now save this as index.html. And then host it, mean you will have to put it on the internet so that everyone can view it. Now i think that you would be knowing it and if in case you do not know it please leave a comment with your email-id and i will mail you how to do it.
Now you can view it by typing the url in the address bar.
NOTE: If u want to send it to the internet, then first you will have to create a hosting account which you can create on www.110mb.com and there are many other sites which you can find on the internet very easily.
I suppose that you created your account at 110mb.com
now login to your account then click on “File Manager”, then click on “upload files” or just “upload”. Then select the file which you want to send to the internet and click on upload. And you are done.
Now you can access you file on the net by just typing the url ofthe file.
And you will receive password of the users that login to your site through email-id which you’ve entered while creating the form.

Disable yahoo from tracking you

As you all know, Yahoo! upgraded its features and the capacities of the mail accounts have grown to 2GB. That’s good for sure, but the “monitoring” methods that we all have been far too familiar with in the last couple of years have been renewed with this move also.

Yahoo! is now keeping track of which sites its members that are getting into groups or using Yahoo! services are visiting and storing this data with a method called “Web Beacons”.
The aim is to give these statistics to the partner companies arranged by agreement and to improve the “advertisement guiding” function. However, those who are bothered by this and do not want to be kept track of have still a choice.
Yahoo! has hidden this option way deep inside somewhere but I’m declaring it here in case there are people who want it anyway:
1. Go to the address code http://privacy.yahoo.com/privacy and click the “Cookies” link under the “Special Topics” column.
2. Click the “Web Beacons” link under the “Reference Links” Column.
3. On this page, click the “click here to opt out” link toward the end of the third paragraph under the “Outside the Yahoo! Network” title.
4. After a while, a page that says you have been out of the monitoring program will load. Without doing anything, close that page or continue your usual surfing by typing another address in the address bar. (Do NOT click the “Cancel Opt-out” button, your action will be cancelled!)
5. You’re done! Now Yahoo! will not record what you’re doing during surfing.You can let your friends that might be interested know about this; since no matter how “innocent” it may seem, it’s still a violation of privacy.
