mail to misp - Email in your threat intel

I receieve a lot of spam and malware via email. Sometimes I can't be bothered to do much with it, but recently I've been picking up doing things with the samples I have been sent. Ever thought about setting up your own "this is a phish button" in your email client? If so, this post may be for you.

Fixing my PPPOE configuration on PfSense

I am moving from a virtual machine on VMWare to a physical host for my firewall. There are many reasons. This machine was the last hold out of my move. I also was upgrading from Pfsense version 2.5.2 to version 2.7.2 as well, which did complicate matters.

pfSense and Tor

I have recently moved from a pfSense vm to dedicated hardware. I may move back, but while I was evaluating the system, I installed TOR ( The Onion Router) package on to my firewall to allow me to route traffic.

Using Kestra to update my proxmox IPSet

I've been using Kestra for a while now to automate some of the more mundane tasks around my network. One of these tasks is keeping the firewall up to date. This blog sits behind cloudflare, and as such, only cloudflare needs to access it. All other sources should be be denied (except internally).

Need extra sponsors to drive your email security program? Want to see your logo in certain mail clients like gmail? If so, then you need BIMI.

Deploying vault via docker and ansible

Adding to my in-promptu series on automating docker containers with ansible, this time I'm looking at Hashicorp's Vault. This is slightly different, in that it required a binary to be installed on the ansible controller (a raspberry pi). Once vault is deployed, we need to unseal the containter.

Monitoring DMARC with Docker

In this post, I deploy a docker container via docker compose and ansible to read my dmarc reports.

Wireless doorbell hacking

I bought a wireless doorbell from B&M and the doorbell works great. I have always been interested in decoding radio, so this gave me a chance to try this out. My end goal here is to be able to press the doorbell and have home assistant act on the button press.
