Okay, this isn't new but I never got to the point to actually talk about this here. While HTTP source streaming is a very basic concept, I noticed that not everyone noticed it's principle and that some programmers still don't understand security. In certain cases programmers need to stream a file to the screen. The problem arises when programmers are streaming hardcoded files to the screen instead of stored file pointers. The URI is not designed to correlate files, it's meant for the basic scheme and it's optional query string parameters.  read more »

Today I had time for another shot at my new .htaccess, and I can tell you that it got better. I think it's pretty much done now, and I am really happy with it. I also got a couple of questions about how it exactly works. So I post my latest .htaccess here, plus a walkthrough on the various mod_rewrite rules I use.

First off, here is my latest beauty:  read more »

RewriteEngine On
Options +FollowSymLinks
ServerSignature Off

RewriteCond %{REQUEST_METHOD}  ^(HEAD|TRACE|DELETE|TRACK) [NC,OR]
RewriteCond %{THE_REQUEST}     ^.*(\\r|\\n|%0A|%0D).* [NC,OR]

Ah well, pun intended. :)

Looks like Ning.com is vulnerable to XSS, and quite a bit at it. I signed up on PDP's new social network called House of Hackers. It seems that Ning let us edit the stylesheet, obviously they never heard of CSS XSS moz-binding attacks otherwise this would not work. These XSS attacks can be launched from a stylesheet.

Alright this is fun and a bit old school, I finally got around to write about this too. What I will be talking about is a trick to fool users in userland to into executing an executable. Which is really one of the most used techniques in trojan or virus writing, and it can be very reliable. The trick is to let the user think that the action he is about to take is legitimate. Like clicking on a JPG, which actually is an executable and will be treated as such. Imagine this simple scenario;  read more »

A recent survey shows organizations are worried about risks posed by employees and increasingly interested in training as the network perimeter continues to crumble.

Today I decided to give a very brief example on pharming and why it's so easy to pharm surfers with little or no skills. Usually, browser exploit writers give simple examples on how to read the boot files, or launch a calculator. There is so much you can do with Javascript that the best way to describe the toxic mix of browser exploits with Javascript will be an example to launch a pharming attack. The sheer beauty of pharming is that the surfer will almost never know that he has been compromised, because it is very silent.  read more »
