Running some Ubiquiti UniFi equipment, I’ve also got a USW-Flex-Mini 5 port switch in my setup. Turns out it’s easy to mess up one’s config for them, when taking shortcuts. Here a little insight into the issue, supported features and the solution for the Flex Mini.

I recently wanted to understand why a product, which was certified following multiple different standards was so easy to pwn. Thus, I got to read a few standards..yay… Here a few random thoughts.

Needing a victim for an OT related talk, I decided to hit eBay and quickly found a cheap offer for a few Hirschmann industrial router/firewall/VPN node “EAGLE One” . For about 25Euro each, they were perfectly in budget and although it was the old and seemingly EOL version, I ordered two and had a look.

So I recently got a Hantek 2D72 handheld scope, signal generator and multimeter. Here’s a short review

Since our first Packetwars at H2HC in 2015, it has somehow become a fun tradition. Although not having been involved in 2018, I was back this year and brought a few fun but seemingly too uggly challenges. Here is a short write up on the concepts, ideas and challenges.

A few months ago a friend asked me whether I’d be prepared to assist the Hacker Jeopardy staff to create a fun little prize for the 25th jubilee edition. After talking cool ideas, steampunk, nixie tubes and badges, we changed over to a small diorama of the HJ stage. All in all it resulted in the production of a limited edition of 15 Nixie tube clocks.

It seems that Hackers have a significant interest in Adrenaline and Epi-Pens: How they work, what they look like and how to use them. So, due to “having access”, I decided to write a short post with a “demo”. Obviously, above being interesting, it’s good to know how to use them.

I’m just on my way home from visiting Blue Frost Security ’s second edition of OffensiveCon . So, obviously, I need to start with a big thanks to Miguel, Lukas and all of the staff for a great conference! Now, sitting on the train with a few symptoms sleep deprivation, I thought I’d drop a few lines a small event I “ran” on the side: Lobby Con!

After having received my new Saleae {:target=_“blank”} Logic Analyzer, I decided to combine my testrun with something I’ve had on my todo list for a few years now: The electronic “Parkscheibe” / parking disc. Thus I ordered one and had a closer look!

About a year ago I was looking for a creative way for bridging about a month of waiting, well bridging the wait for somebody else to be precise. After a little bit of tinkering and playing around I thought it might be a nice idea to send a postcard per day. Obviously, I wanted the cards to be custom (own design), printable (duplex) and somehow connected (telling a story). After a few more days of playing with ideas I decided to add a puzzle aspect, thus each postcard containing a few parts of the puzzle. The way things are with me, the overall design slightly exploded by adding a few more fun features. I’m actually just writing about, as I did quite like the overall idea and thought somebody else might find joy in it or just use it as inspiration, especially as the project turned out to being a complete waste of time.
