Domain back up

Wed, 30 Sep 2015 11:36:26 +0000

Due to a ‘administrative problem’ between my registrar Xs4all and their US-partner Network Solutions, my domain has been offline since Sunday. Resolving the issue took them some time, and there was a technical issue after the administrative one was resolved. Add long DNS TTL values into the mix, and the disruption was quite lengthy. The domain is back up, although it may still take some hours for everyone to see it due to DNS caching.

GPG key update

Mon, 16 Dec 2013 08:54:05 +0000

I have revoked my old gpg keys 0BA788C7 and F5DFF229. They are superseded by 926856B4. You can grab that from http://pgp.mit.edu.

Reason for the update is to get rid of the 1024 bit keys. I have no reason to believe they were compromised :)

Twitter

I’ve finally given in to the hype and got an account on Twitter. I must say that so far I’m liking it more than I expected. It seems almost everyone from the infosec community is active on the service. I am updating it nearly daily about (among other things) the OISF development I’m doing.

Available for contract work

Mon, 05 Jan 2009 13:26:06 +0000

This year there will be a lot of work that needs to be done for the Open Infosec Foundation. And like I wrote a few days ago, a lot of work is already being done. However, most of it is unpaid at this time as it will be some months before our funding comes in. So at least until then I’m available and looking for contract work.

For the last two years I’ve been doing work as a contractor in the (open source) security field. My experience is mostly in coding in C and Perl, primarily on Snort and Snort_inline. Recently I created the (Perl language) SidReporter program for Emerging Threats. Areas I worked in: IPv6 IDS/IPS coding, signature writing, Web Application Firewalls, threading, bandwidth accounting, and more…

Site moved

Thu, 05 Apr 2007 08:05:56 +0000

This site is hosted at a server at my home and is connected using my DSL connection. Next weekend I’m moving and the DSL has to be moved as well. Since that usually takes a few weeks here, I had to move the blog (and my mailserver) elsewhere for a while. Luckily Adi Kriegisch provided me with access to a server, so yesterday both my mailserver and weblog were moved. I have no native IPv6 connection there so I’ve disabled IPv6 access for now. Maybe I’ll try to restore it later. As far as I can see everything works, but if you see any problems please let me know! Big thanks to Adi for hosting my site!

Vuurmuur developments

Fri, 12 Jan 2007 21:47:01 +0000

This is my first blog post in 2007, so let me start by wishing everyone a good and healthy new year. In the new year I finally released a new version of Vuurmuur. It was the longest period between two releases, the last one was in April 06. The last year has been pretty hectic, with my graduation, looking for work, and now working… Also I’ve been stepping up work on Snort_inline and Modsec2sguil, which all took away coding time from Vuurmuur.

Snort_inline: getting closer to 2.6.0.2

Sun, 29 Oct 2006 22:40:29 +0000

I’m back from my vacation which was very nice. Hardly did any geek stuff, other than meeting up with Philippe, who lives in Paris. It was the first time I met someone I got to know through the Vuurmuur project :)

So with Snort_inline things aren’t moving as fast as I hoped, but there is certainly progress. I’m currently hunting for a few bugs. First of all I’ve seen it segfault on me once. Sadly I had forgotten to enable coredumps, so no clue as of why. Second, William and I have been ironing out some issues where the new stream4 mode was getting mixed up with the old. I think these are pretty much taken care of now. Third, there is a bug where an unified alert fired by http_inspect doesn’t contain a payload. Finally, i’m hunting what appears to be a heisenbug in the new stream reassembly, because I’ve never encountered it since I’m actually looking for it.

Vacation!

Since I was very busy this summer with finishing my Master thesis I still owed my girlfriend a vacation. Tomorrow we are leaving for a week of vacation in Paris…

A word about my current employment situation

Fri, 13 Oct 2006 08:19:59 +0000

Yesterday the talks between me and my employer of the last five years broke down in disagreement. The company where I have been working as a part-time Sytem Admin for the last five years next to my study, offered me a job in their webdevelopment team. It wasn’t security related, but it sounded interesting enough since I would mostly work on the backend where connections with databases and third parties would be handled. Anyway, the talks broke down so I’m now looking for work.
