Exploit writing tutorial part 1 : Stack Based Overflows
Last friday (july 17th 2009), somebody (nick)named ‘Crazy_Hacker’ has reported a vulnerability in Easy RM to MP3 Conversion Utility (on XP SP2 En), via packetstormsecurity.org. (see http://packetstormsecurity.org/0907-exploits/). The vulnerability report included a proof of concept exploit (which, by the way, failed to work on my MS Virtual PC based XP SP3 En). Another exploit was […]
Free tool : Find out where your AD Users are logged on into
Hi, I decided to release another free utility I wrote a while ago. This small command-line utility can be used to find out where Active Directory users are logged on into, and/or to find out who is logged on on specific machines. This should include local users, users that are logged in via RDP, user […]
Juniper ScreenOS : Active/Passive clustering
Introduction In this blog post, I’ll show the easy steps to set up a screenOS based active/passive cluster. I’m not going to discuss the configuration of active/active clusters because, in my opinion, this configuration is only needed in rare circumstances and may introduce some weird behaviour issues. Furthermore, active/passive clusters have been working quite well […]
Exchange 2007/2010 : Renaming attachments ‘on the fly’ – custom transport agent
It may sound a bit extraordinary, but I needed to have the ability to change attachment filenames while they were being processed by the transport service on Exchange. I can’t really tell you why I needed this functionality, but I guess there could be many reasons to do so. (e.g. zip files should be renamed […]
Fixing Exchange 2007 Offline Address Book generation (oalgen) and distribution issues
Today, I’m going to share some ‘notes from the field’ about fixing oab issues in Exchange 2007 In order to fully understand the oab generation and distribution process, I will assume that you are running the Mailbox server role and HUB/CAS server roles on different servers. Of course, this is not a requirement to run […]

Juniper ScreenOS : default route manipulations and redistributions
The default route or “route of last resort” is an important route in most present inter-network connectivity configurations. It contains all public and private routes possible and is responsible for directing traffic to a next hop when no better route is found. In most cases, it is used to allow networks to access the internet, […]
Free tool : Windows 2003/2008 Certificate Authority Certificate List Utility for pending requests and about-to-expire certificates
In one of my earlier posts, I have talked about setting up a Windows 2008 based Certificate Authority/PKI. Once your Windows 2008 CA setup is in place and configured, you can go ahead and starting issuing certificates. But at the same time, you need to put a maintenance/management procedure in place so you can stay […]
Juniper ScreenOS : defeating iBGP full mesh requirement using route reflectors and confederations
As explained in one of my earlier posts, one of the requirements to successfully setup and operate an iBGP configuration is that all iBGP clients need to have a BGP connection to all other iBGP clients. (= full mesh). This is required because an iBGP device only exchanges information about its own networks and it […]
