Is AI good or bad? It doesn’t matter. What matters is that it is up to the infosec community to fix it, whether we want to or not.

APT and Sendmail Monitoring
Instead of simply discarding incoming phishing emails from APT actors, I decided to make sure it was loud and clear in mail logs that I discarded them - with attribution.
Network Updates
Everything on the network is finally done. Oh who am I kidding? Things change constantly between software and hardware updates and upgrades. This just documents a small part of it.
Using AI Responsibly
I wanted to use AI but in a way that was responsible, didn’t dig into my privacy, and helped me to get what I want. One might say I am “hacking” AI. Maybe I am. I’m trying to get it to do what I want it to do on my own terms - the essence of hacking. But first, I had to devise a test. Granted, this test is for my needs, but maybe you might find it interesting as well.
LGBTQ+
I was asked by a friend why I was a supporter of the gay community. I didn’t realize I was, I thought I was just being accepting to everyone.
Using AI Code Generation Securely
I did a bit of an experiment with several LLMs and code generation, and one of them actually seemed to perform slightly better from a security perspective.
Network Review 2025
Unsurprisingly to other techies my server rack has changed over the past year and few months. Warning, nerd territory ahead.
MTA-STS: Why and How I Did It
I closed a security hole on my mail server. Granted, one could barely see the hole, and the chances of compromise are quite low, but everything counts. Right? Right?
Installing Wireguard
There are a lot of decent tutorials online about Wireguard setup. I’m not claiming this is one of them, but this is about a real world implementation.
My Pi-hole Rabbit Hole
Running Pi-hole in recursive mode has a lot of benefits - especially if you run your own mail server.
Network Revamp 2023
To save on server room space as well as power consumption, I migrated three tower systems to Intel NUCs and rack mounted them. Here’s why.
Fun Friday: The Great Pharmacy Heist
Destroying infrastructure to cover for a crime is hardly a new phenomena…
Past Predictions
Instead of making predictions, I look back at past predictions, particularly the outlandish ones, just to see how well I did.
Mastodon and Self-Hosting
Hosting your own Mastodon instance isn’t for everyone, but if you decide to do it, it’s probably easier than you think.
Old Weird Hacker Things
Yes, all of the things that needed fixing were fixed ages ago. But still…
Locking Down Accounts
If you set up SSH on a server, you should also lock it down.
Daemon
To properly run a mail server, you need your DNS in order. This is my over-the-top method to do just that.
Advancing Persistently Against APT
It’s all fun and games until a PRC-sponsored attack group gets personal.
Talon
There are reasons I run my own mail server, they may seem paranoid but they are not. Well. not too paranoid...
The Home Network Overhaul
I moved everything to UniFi, then they had a major breach. I’d do it again the same way regardless.
