My previous intro post was a few years old, so behold, new intro post:

Mike. Live in the Seattle area having grown up in the UK as a full blown British. Have a wife (incredible), child (boy), and three dogs (golden retriver/cream retriver/fuck knows).

I work in information security, something I have done for about 20 years. By day I run corporate security, enterprise IT and various other bits and pieces for an EV charging startup. I am big into EV's and currently drive one that is not a Tesla. I want an electric motorbike, so if anyone has a spare one please send it.

I also have a company of my own, Secure Being (securebeing.com), which does pen testing and digital forensic work - it's my way of staying super hands on while still doing the management bits on the career path.

I have written books about information security things. Five of them. Two are non-fiction textbooks, and three are fiction based on real world #infosec things. Check out infosecdiaries.com and your local bookstore to find them, just search for my name. I have been trying to write more stuff, but always seem to find myself distracted by other things, such as work. linktr.ee/secureowl has some mini stories I've written.

I love radio and everything RF. I have lots of antennas and various scanners and radios on my desk. I love intercepting and decoding things, like digital radio protocols.

I am a big aviation nerd. I always wanted to be a commercial pilot. I gained my private pilots license in the UK at 17, all self funded by my employment at the local Safeway/Morrisons store. I did the sim test and commercial assessments, but for some reason, at 18, I was unable to find the £100k needed to complete the commercial training, so I did computers. But do not worry, because those computers and love of aviation and radio/RF combined, and I run a project called ACARS Drama. acarsdrama.com has all the details.

I play guitar and am a big guitar/audio nerd as well. I record music under the moniker Operation: Anxiety, operationanxiety.com - the music is on all the normal places.

Finally, I am a massive fan of motorsport. I believe I have watched every F1 race for the last 30 years, maybe 25. I also follow F2, FE, Indycar and MotoGP closely. I average around 18 hours of Le Mans 24 hour racing watching per year.

So there you have it. If you are looking for a thought leader on the topics mentioned above, you've come to the wrong place - because this is where I shitpost, and shitposting is cheap therapy.

“Off We Go To War: Starmer’s Strategic Defence Review”

by Binoy Kampmark in Savage Minds on Substack

“Unpopular governments always retreat to grounds of lazy convenience. Instead of engaging in exercises of courage, they take refuge in obvious distractions. And there is no more obvious distraction than preparing for war against a phantom enemy”

Zero Retries · Zero Retries 0200By Kay Savetz K6KJN

While admitting that most of the Zero Retries amateur radio newsletter is way over my head — and I'm a General Class license holder — I was able to pull out of the most recent issue that THIS IS THE RADIO TO GET (and to beat):

@micahflee lemme guess: @eff just took a multi-network eSIM and multi-network WWAN modules to scan for "#deauth" / "#EvilTwin" attacks?

Cuz I remember @heiseonline or @golem actually suggest this as a method to detect #IMSIcatchers without requiring an expensive #SDR:

  • By precisely looking when which WWAN stick (for #3G back then) got disconnected and warning if they all got disconnected & reconnected at the same time...

AFAIK #GSMK uses that same technique for their #Baseband-#Firewall to automatically detect #Interception attempts and deploy countermeasures!

Does anyone know any #SDR tools (maybe a #GNURadio script?) to turn an SDR into a wideband scanner? Or is there a clever frontend device that can do that?

I have a nice SDR (LimeSDR Mini) that’ll do 20+MHz bandwidth and 0-3GHz, but what I really want is a visualisation of large chunks of spectrum (100MHz minimum, ideally full range) to identify congestion and rogue transmitters in our building on all ISM, FM, DECT, RadioMic, TV, WiFi, etc. bands.
I understand that it’ll be slower, having to sweep across the frequencies, but averaging over minutes is fine.
But there are spectrum monitoring devices around that seem to manage it somehow.
