Attacks such as thisa multi-stage miscellany of IE and Mediaplayer bugs that resulted in the "silent delivery and installation of an executable on the target computer, no client input other than viewing a web page" were reported with regularity.
So what has become of the multi-stage attacks - have they become redundant? The answer to this, which I'm sure you can guess, is a resounding "no" and will be emphatically demonstrated in my upcoming Black Hat talk "The Internet is Broken: As a teaser for that, I'm going to revisit an old attack - pre-computed dictionary attacks on NTLM - and discuss how we can steal domain credentials from the Internet with a bit of help from Java.
I'm going to split it into two posts. In my next post we'll consider its impact on Windows Vista. In a nutshell, this attack works as follows: Position yourself on the Intranet. Coerce a client, either actively or passively, into connecting to a service such as SMB or a web server on your machine.
Request authentication and supply a pre-selected challenge.
Capture the hashes from the NTLM type 3 message and crack them using rainbow tables or brute force. A requirement of this attack is for the attacker to be located on the Intranet. There have been suggestions on how to remove this necessity; see this post for a discussion on DNS rebinding as a potential solution.
Let's take a step back though and begin by reviewing IE's criteria for determining whether a site is located on the Intranet or the Internet: By default, the Local Intranet zone contains all network connections that were established by using a Universal Naming Convention UNC path, and Web sites that bypass the proxy server or have names that do not include periods for example, http: If we were therefore able to fully control a web server on the local machine, headers and all, and we were able to cause IE to connect to it, we could ask IE to authenticate allowing us to use a pre-selected challenge in order to carry out a pre-computed dictionary attack.
But how does a malicious website run a web server on your machine? This is where the Java browser plugin comes into play A Web Server in Java There is nothing to stop an unsigned Java applet from binding a port provided the port number is greater than The same origin policy, which I've discussed previously is enforced when the applets accepts a connection from a client; only the host from which the applet was loaded is allowed to connect to the port.
If a different host connects, a security exception is thrown, as shown below. This means that if we can make the applet think it was loaded from localhost, we can bind a port and act as a web server, serving requests originating from localhost.
I have previously covered two ways of manipulating the applet codebase the verbatim protocol handler and defeating the same origin policybut these flaws are now patched.
We can accomplish the same effect on the most recent Java browser plugin by forcing content to be cached in a known location on the file system and by referencing it using the file: So if we know that our class was stored at c: So this attack effectively boils down to caching content in a known location.
There are, however, multiple ways of silently getting content onto the local machine with a fixed name. And thats all I'm going to say for now; we'll be addressing this topic further in our Black Hat talk:Jul 08, · How To Write a Good Cover Letter Postscript P.S.
