Microsoft Internet Explorer is prone to a remote code-execution vulnerability.

Attackers can exploit this vulnerability to execute arbitrary code in the context of the user running the application. Successful exploits will compromise the application and possibly the underlying computer. Failed attacks will cause denial-of-service conditions.

This Vunerability will be easy exploit thorugh metasploit modules. This IE_XML exploits a vulnerability in the XML handling code of Internet Explorer. In order to execute code reliably, this module uses the .NET DLLmemory technique pioneered by Alexander Sotirov and Mark Dowd. This method is used to create a fake vtable at a known location with all methods pointing to our payload. Since the .text segment of the .NET DLL is non-writable, a prefixed code stub is used to copy the payload into a new memory segment and continue execution from there. This code is a very early version of what the final implementation will be and the API and this module will continue to be updated as progress continues.

In computer science, session hijacking refers to the exploitation of a valid computer session to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a remote server. It has particular relevance to web developers, as the HTTP cookies used to maintain a session on many web sites can be easily stolen by an attacker using an intermediary computer or with access to the saved cookies on the victim's computer.

TCP session hijacking is when a hacker takes over a TCP session between two machines. Since most authentication only occurs at the start of a TCP session, this allows the hacker to gain access to a machine.

A popular method is using source-routed IP packets. This allows a hacker at point A on the network to participate in a conversation between B and C by encouraging the IP packets to pass through its machine.

If source-routing is turned off, the hacker can use "blind" hijacking, whereby it guesses the responses of the two machines. Thus, the hacker can send a command, but can never see the response. However, a common command would be to set a password allowing access from somewhere else on the net.

A hacker can also be "inline" between B and C using a sniffing program to watch the conversation. This is known as a "man-in-the-middle attack".

In this video from learn security online will show us session hijacking using a tool ferret and hamster.

One of the most common techniques used by hackers to penetrate your network, is just plain-old password guessing. This goes for external hacking attempts as well as internal hacking attempts.This is the scenario how hackers can use tools to perform brute force password hacking in your Terminal Server environments and what you can to prevent these kinds of attacks.

Terminal Server environments are juicy targets for hackers. In this article I showed some techniques hackers can use to perform brute force attacks against local administrator accounts. I also showed you what you can do to prevent these attacks. Please keep in mind that these are just pointers and only make up a small part of the steps you should take to secure your Terminal Server environment.

This exploit is very critical because it will attack the client. Why the client is so danger to this vulnerability? Ok let's we make some illustration here. The bank. Bank have a very good security procedure. So it almost impossible to attack it. And let's take another way "the client" what do you think?

The question is who is the client? what they use to open the e-mail? what is their operating system? what version is it? what is the browser they use? All of this question will you get if you do the social engineering technique. So when you get that information you can use some client side exploit like this example.

So, what the solution? Nothing we can do against this. All we can do is patch from the vendor. My solution here is learn some skill from bad guy world so you know how they do this and know how to prevent that. This video taken from offensive-security.

This is video an old video and i think this video very awesome. this is scenario where it will tunneling some old exploit "dcom exploit" through SSH. As i read many source from the internet, they (security expert) say never put your trust 100% on security software, it just will help us to do a job. When the first time i read that, i don't believe it, but what can i say it true. The fact everyday there are many exploit out there public exploit or private exploit that have been created to hack in the server.

This video i get from the hackingdefined and this is by muts aka mati aharoni the author of backtrack. He create a good scenario here with a picture that make everybody understand.

This video will present how to do metasploit autopwn. it mean the framework ( Metasploit ) will search the exploit that match with the open port ( scan with Nmap ) from the victim computer. This feature from metasploit is very good for penetration tester to minimize a time for testing the server or computer client.

This how usually people installing backtrack clean install. clean install mean no change at all from the source or never touch from the user. This video guide installing backtrack taken from offensive security from the author or maker of backtrack.

So i hope this video will help you installing backtrack a lot of easiar because i think it's very obvious and visually. And voice for explaination. Excellent video, and i recommended to see it first before installing backtrack to your harddisk.
