When the victim navigates to the link it will open a active Meterpreter session that we are connected to. The browser will hang, but we will have activity at our msfconsole. When the victim tries to load the page, nothing will be displayed. To do so, just add the following tag to your html anywhere inside the element: In order to get your target's browser to load your malicious URL, you can either send it to them directly, or embed it in an iframe on your perfectly innocent website. The one we want is /exploit/windows/browser/ie_unsafe_scripting.
Msf> search type:exploit platform:windows unsafeĪs you can see from the screenshot below, this search brought 15 exploits. Let's find the appropriate exploit by searching Metasploit for a Windows exploit that takes advantage of unsafe scripting. Fire up your Metasploit ( click here for an intro to Metasploit) on Back Track 5 and let's get cooking! Step 1: Find the Appropriate Exploit In our example, we will use IE 8 on Windows Vista, but it will work on any of the operating systems listed above with Internet Explorer 8.1 or earlier on it. When Windows 7 and Windows Server 2008 were released, the default browser was IE8, so unless the target has upgraded their browser, this vulnerable browser is still on their system and we can hack it. In this hack, we will exploit Microsoft's Internet Explorer 6, 7, and 8 on Windows XP, Vista, Windows 7 or Windows Server 20. In other words, we find a variable in the system software that can be overflowed with too much information and jam our software behind it (kind of oversimplified, but you get the idea, I hope). Just as a background note, nearly all of these hacks I have shown you so far are buffer overflows. Now, I will begin to explore ways to hack the client side of the equation. So, as you would expect, the best hacks are now coming at the client side software. Server operating systems have become more secure, while clients are loaded with insecure software that can be easily exploited. In other words, we have exploited a vulnerability usually in an operating system service ( SMB, RPC, etc.) that all allow us to install a command shell or other code in the target system.Īs I have mentioned numerous times previously, the art of hacking is presently focused on attacking the client side rather than the server side. All of my hacks up to this point have been operating system hacks.
