How to Protect an Email Account from being Hacked

Today in this post I’ll teach you how to protect your email account from being hacked. Nowadays I get a lot of emails where most of the people say “My Email account is hacked please help…”. Now one question which arises in our mind is:”Is it so easy to hack an email account? OR Is it so difficult to protect an email account from being hacked?”. The single answer to these two questions is “Absolutely NOT!”. It is neither easy to hack an email nor difficult to protect an email account from bieng hacked.

If this is the case, then what is the reason for many people to loose their accounts?
The answer is very simple. They don’t know how to protect themselves from being hacked! In fact most of the people who loose their email accounts are not the victims of hacking but the victims of Trapping. They loose their passwords not because they are hacked by some expert hackers but they are fooled to such an extent that they themselves give away their password.

Are you confused? If so continue reading and you’ll come to know…

Now I’ll mention some of the most commonly used online scams which fool people and make them loose their passwords. I’ll also mention how to protect your email account from these scams.

1. WEBSITE SPOOFING

Website spoofing is the act of creating a website, with the intention of misleading the readers. The website will be created by a different person or organisation (Other than the original)especially for the purposes of cheating. Normally, the website will adopt the design of the target website and sometimes has a similar URL.

For example a Spoofed Website of Yahoo.com appears exactly same as Yahoo Website. So most of the people believe that it is the original site and loose their passwords. The main intention of spoofed websites is to fool users and take away their passwords. For this,the spoofed sites offer fake login pages. These fake login pages resemble the original login pages of sites like Yahoo,Gmail,Orkut etc. Since it resemble’s the original login page people beleive that it is true and give away their username and passwords by trying to login to their accounts.

Solution:

• Never try to login/access your email account from the sites other than the original site.
• Always type the URL of the site in the address bar to get into the site.Never click on the hyperlink to enter the site.

2. BY USING KEYLOGGERS

The other commonly used method to steal password is by using a Keylogger. A Keylogger is nothing but a spyware. The detailed description of keylogger and it’s usage is discussed in the post Hacking an email account. If you read this post you’ll come to know that it is too easy to steal the password using a keylogger program. If you just access your email account from a computer installed with keylogger, you definitely loose your password. This is because the keylogger records each and every keystroke that you type.

Solution:

Protecting yourselves from a keylogger scam is very easy.Just install a good anti-spyware program and update it regularly. This keeps your PC secure from a keylogger. Also there is a program called Anti-keylogger which is specially designed to detect and remove keyloggers. You can use this program to detect some stealth keyloggers which remain undetected by many anti-spyware programs.
3. ACCESSING YOUR EMAIL ACCOUNT FROM CYBER CAFES

Do you access your email from cyber cafes? Then definitely you are under the risk of loosing your password.In fact many people loose their email account in cyber cafes. For the owner of the cyber cafe it’s just a cakewalk to steal your password. For this he just need’s to install a keylogger on his computers. So when you login to your email account from this PC, you give away your password to the cafe owner. Also there are many Remote Administration Tools (RATs) which can be used to monitor your browsing activities in real time.

This doesn’t mean that you should never use cyber cafes for browsing the internet. I know, not all the cyber cafe owners will be so wicked but it is recommended not to use cafes for accessing confidential information. If it comes to the matter of security never trust anyone, not even your friend. I always use my own PC to login to my accounts to ensure safety.

Intro

The purpose of this article is NOT, I repeat, NOT to teach someone how to “hack an email account”. It’s true purpose is actually MUCH more devious. The purpose of this and all other articles in the “An Exploit Explained: ” series is to teach readers about various web technologies, and the basics of security and exploiting. I will try to give you a hands-on, learn as you go type of education in computer security. Sound good??? Then let’s get in to it!!

Preface

On Wednesday, Sept. 22 1999, yet another bleary day in the life of little v, the following message was sent to my inbox:

To: BugTraq
Subject: Yet another major Hotmail security hole -
injecting JavaScript using "javasCript:"
Date: Wed Sep 22 1999 10:48:04
Author: Georgi Guninski

Yet another major Hotmail security hole - injecting
JavaScript using "javasCript:"

There is a major security flaw in Hotmail which allows
injecting and executing JavaScript code in an email
message using the javascript protocol. This exploit
works both on Internet Explorer 5.0 (guess IE 4.x)
and Netscape Communicator 4.x. Hotmail filters the
"javascript:" protocol for security reasons. But it
does not filter properly the following case:
"javasCript:" where "C" is the ASCII code of "C".

So the following HTML is executed 
if the user has enabled automatically loading of
images (most users have).

Probably this may be used in other HTML tags.

Executing JavaScript when the user opens Hotmail
email message allows for example displaying a fake
login screen where the user enters his password
which is then stolen. I don't want to make a scary
demonstration, but I am sure it is also possible to
read user's messages, to send messages from user's
name and doing other mischief. Hotmail deliberately
escapes all JavaScript (it can escape) to prevent such
attacks, but obviously there are holes. It is much
easier to exploit this vulnerability if the user uses
Internet Explorer 5.0. AFAIK this is not a browser
problem, it is Hotmail's problem.

Workaround: Disable JavaScript

The code is:

Ok, don’t puke, I’m going to explain what just happened in a fashion that even your dog can understand.

What is this all about?

This important part of this posting to the Bugtraq(1) (http://www.securityfocus.com) mailing list is the actual exploit(2).
The exploit would be:

What does it do?

As this exploit, when put into an email message sent to a hotmail user, opens a little box using the “alert()”(3) function in javascript(4), and is also supposed to read who the first message in your inbox is from. However, this code does not work on its own. You see, the email also says that you need to use the ASCII(5) code for “C” in the message. If I get out my handy HTML reference book, I can see that the ASCII code is C. If we substitute this into our little exploit, minus the “read who the first message in your inbox” part, we get this:

How does it work?

Finding out how an exploit works is always the part that makes people a bit spindizzy. If we look at that gibberish we call code one more time we can see that it uses an tag, which all you who took my HTML tutorial would know is to display an image onto the page. Because hotmail tries to be the “top dog” webmail provider, they allow you to set autoloading of images, so the image just shows up on the same page as the mail. When you open a new hotmail account, this option is already set (hurray!). The conflict happens because your normal browser allows you to put javascript tags into your IMG tags. Because JavaScript is a strong little language, and allows just about full control over someone’s browser, if the conditions are right. Naturally, people like you and me started exploiting hotmail’s allowing of javascript. Soon, the
