Nice little one-liner to restart all failed services on OpenBSD:

rcctl start $(rcctl ls failed | awk 'BEGIN{ORS=" "}{print}')

I am really glad about the paradigm shift the pandemic brought into my workplace with regards to remote work. Being able to stay at home 80% of my time is something I grew to be fond of and it helped a lot overcoming some personally challenging situations during the pandemic. I really enjoy the …

A while ago I decided to ditch my Windows machine at home as I never really felt at home with the way Windows made me handle the system and the overall `ergonomics' of the OS. Sure, things got better with the introduction of powershell, winget and the Microsoft Terminal but still I always felt like …

There was a discussion lately at my workplace about how to label cables. Currently our cables at the datacenter sadly haven’t been labelled by the previous staff which makes tracing them a nightmare as cables tend to span multiple racks.

So I went ahead and proposed some types of labels I came …

So I am back on Vultr. Kind of. Not that I am disappointed with hetzner but I just want to run my stuff at home just like I was doing when I started getting more into being part of the Internet and before running your mail server from home became more or less impossible. I still like thinking of the …

Completed the Wifi Security Bootcamp at Pentester Academy :-)

Lately I lost the masterkey to my Bitwarden vault. As Bitwarden does not provide a way out of that rabbit hole, losing my masterkey would mean losing all of my data within the vault. Something around 300 entries.

Luckily I had access to the vault on one of my computers as the vault has not been …

Lately I started thinking about my future and whether I should keep my self employed or if I should finally start working on being either self-employed or start my own company. Yeah, interesting timing in such uncertain economic times but I guess they’ll stay uncertain no matter what. As I am …

Wasn’t much going on lately. First work kept me busy, then COVID19 came along and with it homeschooling next to having to work. So for me, COVID19 kept me even more busy. Which feels strange because a lot of people seem to have a lot of spare time at their hands. Still I managed to migrate my …

Finally certified. Too bad I haven’t found the time to tackle the Advanced+ certification but there are enough machines left in the lab and I am pretty sure that I will revisit the lab for the Advanced+ certification, too.

I had a lot of fun in the lab and the guys were quick to respond …

I will use this post to publish my progress while working on virtual hacking lab. It does not have the same reputation as OSCP but I do enjoy the lab and am very pleased with the lab material and dashboard. Also support is quick and nice if you need it (not for clues, of course!). The lab is also …

Recently I had the chance to get myself a copy of a malicious httpd executable used by an unknown party while exploiting CVE-2019-19781. Even though I do not have anything else but a layman’s understanding of forensics I still wanted to dig into it. This is my journal about a journey into …

While working on my DNS firewalling @home I was studying unbound.conf and found what I already had forgotten, unbound’s DNS rebinding protection.

DNS rebinding is a an attack where a malicious website is using your browser to resolve internal addresses (e.g. RFC1918) in order to get their …

There’s one thing that I am really missing under OpenBSD, a network manager which seemlessly handles running around with my laptop. So my main itches to scratch are doing magic things at boot and resume so I don’t have to bother with fiddling with hostname.if(5) ever.

My first take on …

A night without sleep later I am slowly getting a clearer picture of how the pieces are fitting together. Ricing my blog is getting smoother and smoother as my understanding of sblg, HTML and CSS increases and I was able to unclutter both my Makefile and the HTML code. But there is a lot of …

So. After losing my old disk due to operator error my previous blog (based on jekyll) had been totally lost. Note to self: don’t lose the keydisk to your backup.

So years and a new domain later I decided to reboot the thing, now based on sblg. It’s not yet finished as a lot of edges are …
