How to hack Account with Cookie stealing

How to hack Email account:

If you are a newbie and don’t know about cookie, then for your information, Cookie is a piece of text stored on user computer by websites visited by the user. This stored cookie is used by webserver to identify and authenticate the user. So, if you steal this cookie (which is stored in victim browser) and inject this stealed cookie in your browser, you can imitate victim identity to webserver and enter hisEmail account easily. This is called Session Hijacking. Thus, you can easily hack Email account using such Cookie stealing hacks.

Tools needed for Cookie stealing attack:

Cookie stealing attack requires two types of tools:

1. Cookie capturing tool
2. Cookie injecting/editing tool

1. Cookie capturing tool:

Suppose, you are running your computer on a LAN. The victim too runs on same LAN. Then, you can use Cookie capturing tool to sniff all the packets to and from victim computer. Some of the packets contain cookie information. These packets can be decoded using Cookie capturing tool and you can easily obtain cookie information necessary to hackEmail account. Wireshark and HTTP Debugger Pro softwares can be used to capture cookies.

Update: Check out my Wireshark tutorial for more information on cookie capturing tool.

2. Cookie injecting/editing tool:

Now, once you have successfully captured your victim cookies, you have inject those cookies in your browser. This job is done using Cookie injecting tool. Also, in certain cases after injection, you need to edit cookies which can be done by Cookie editing tool. This cookie injection/editing can be done using simple Firefox addons Add N Edit Cookies and Greasemonkey scripts. I will write more on these two tools in my future articles.

Drawbacks of Cookie Stealing:

Cookie Stealing is neglected because it has some serious drawbacks:

1. Cookie has an expiry time i.e. after certain trigger cookie expires and you cannot use it to hijack victim session. Cookie expiry is implemented in two ways:
   1. By assigning specific timestamp(helpful for us).
   2. By checking for triggers like user exiting from webbrowser. So, in such cases, whenever user exits from his browser, his cookie expires and our captured cookie becomes useless.
2. Cookie stealing becomes useless in SSL encrypted environment i.e. for https (Secure HTTP) links. But, most Email accounts and social networking sites rarely use https unless vicitm has manually set https as mandatory connection type.
3. Also, most cookies expire once victim hits on LogOut button. So, you have to implement this Cookie stealing hack while user is logged in. But, I think this is not such a serious drawback because most of us have the habit of checking “Remember Me”. So, very few people actually log out of their accounts on their PCs.

So friends, this was a short tutorial on basics of how to hack Email account using Cookie Stealing. As I have stated, Cookie stealing has some disadvantages. But, I think Cookie stealing is a handy way to hack an Email account. In my next articles, I will post detailed tutorial to hack Facebook and Gmail accounts using Cookie stealing. If you have any problem in this tutorial on how to hack Email account using Cookie stealing, please mention it in comments.

SMTP Mail Sending Problems – How to Solve them

Posted on June 11, 2013 by hostingguide Publisher

By: Devis Eliot

SMTP is the abbreviated form of Simple Mail Transfer Protocol, extensively used by the servers for sending emails. Neither sending or receiving emails was a great problem even two decades ago. With help of an SMTP mail server, any body could send emails across the net. An unavoidable but unexpected spanning problem emerged and it posed a threat to both sending and receiving email. As a result Internet Service Providers made some significant changes in their functioning to overcome this spamming problem. Verifying that the sender of an email is not a spammer but a genuine owner is a way to sort out this junk email problem, commonly known as spamming problem. The verification is done by checking if the person is connected to an authorized ISP network.

Email senders experience several SMTP mail sending problems. The most common of them is encountering the ‘Bad login’ error. Such problem may occur due to the mismatch between Username and Password. When you are notified about unsuccessful login, the first step is to check your hosting account. In case, the email account has not been successfully created, the error message will continue to generate whenever you try to log in. The next step to eradicate the SMTP mail problem is to verify if you have input in the correct username. As long as the correct username is not given, you will experience the bad login problem. Users often forget the password especially if they have several email accounts. One method to solve this issue is going to Cpanel or Plesk and find out if you have provided the correct password for the specific username or not.

Another irritating SMTP mail problem is when the ‘Server not found’ error flashes on the screen. If you encounter this problem, first check whether the internet connection has been set up rightly or not. Internet connection is the must-have requirement to have an access to the SMTP service provider. If you are sure that there is nothing wrong with the internet connection, then get your email client setting checked. Such checking is advised to ensure that you are using the correct SMTP mail server. An SMTP server is generally recognized as mail.userdomain. But there are many Internet Service Protocols that mandate the use of their own SMTP mail servers. So, know the actual requirement of your ISP technical support.

If an individual is using a newly registered domain name, he may encounter the same ‘ Server not found’ message. The reason is that the domain does not propagate on the net as soon as the new registration is done. So, indicating your client to mail.userdomain will not work at this moment and you have to bear this problem at least one day. Another SMTP mail sending problem is when an immediate message ‘Mailbox full’ in response to your email pops up on the screen. It is not a problem of your SMTP service provider. The message simply indicates the address box of your receiver is filled up to the brim. In such a case, you can only advise him or her to delete some of the messages.
