DirBuster Dictionary Populator

Posted by cirrus

Dirbuster and dirb are in the toolset of all web application security fans. Both tools are excellent (although I prefer dirb due to it being command line and not Java), but their results obviously depends on how good the wordlist you are using is.

How to stop Google Analytics

Posted by cirrus

Yes I know google owns us, yes I know we are using analytics as well.

What you need:
- a web server
- place the two files in this file in the root of the web server
- edit your hosts file and add this entry (where xxx.xxx.xxx.xxx is the IP of your web server):
xxx.xxx.xxx.xxx www.google-analytics.com ssl.google-analytics.com

Now every time you visit an analytics-enabled page, the two files from your web server will be included, and all javascript will be executed properly, but google will not track you.

Windows simple backdooring

Posted by cirrus

I remember reading this ages ago, and a couple of weeks ago I decided to give it a try.
I was amazed to see not only that this works, but that it even works on Windows7. Granted you do need some extra steps to make this happen in the later.

MacOSX Sandboxes

Posted by cirrus

MacOSX Snow Leopard implements a sandbox facility.

According to the sandbox manpage:
The sandbox facility allows applications to voluntarily restrict their access to operating system resources. This safety mechanism is intended to limit potential damage in the event that a vulnerability is exploited. It is not a replacement for other operating system access controls.
