The Rabbit Hole

Preventing 2FA Crises

So...you've heard about using two/multi factor authentication (or 2FA/MFA), and hopefully you've already started using it...😅 A recent podcast episode I listed to detailed the painful process of what could happen if you lose your 2FA codes, and I hope to address how to prevent this even

GitHub action security

This is mainly a high level overview of some best practices I've been thinking about while contributing to an open source project recently, and mainly a note for me on how to use some of the cool features I've been playing with 😅.  This is much more extensive documentation than my

Deleting versions from a Linode s3 bucket

So...this wasn't as straight forward as I thought... Problem/story Enabling versioning for s3 buckets is standard practice for terraform's s3 backend, which Linode supports...kind of... While yes technically Linode supports the versioning, it doesn't support deleting the versions from the web-ui... 🤦. Alright, that's fine I've heard they

PikaPods

tl;dr: PikaPods is an awesome + cost effective place to host your blog 🥳 quick side-note: first time I've seen a picture of a pika and they are so cute 😅 Uptime I've been hosting my blog on PikaPods for probably close to a month now, and I've loved it! I kept

Customizing the Casper theme

So, I think I did this because I wanted to add analytics to my blog and I read somewhere that code injection could potentially be wiped out (which hasn't happened for my css modes yet).  So, I forked the Casper theme GitHub (GH) repo and started making modifications to it.

vagrant

Enabling clipboard support for vagrant-libvirt (vagrant-libvirt clipboard)

So, I think I have mentioned how much I LOVE vagrant 😁 One of the things that I normally never do, is use the GUI of whatever VM I am using vagrant to control. Even if I am using the clipboard for vim or my web browser for my automated vagrant

packer build in a container...? 🛳️🤔

tl;dr: I was able to run a packer build command, for my packer-kali_linux project, inside of a Fedora toolbox container which I had installed HashiCorp's packer and qemu/kvm...and that is just the start of the inception... 🙃😅 So...I am a weird individual... 😅 my normal setup for

disaster recovery to Proxmox

Just to clarify I am doing this as more of a retroactive post to show how I migrated from my xcp-ng server ( I had some weird network sh!t go down...and I honestly didn't probably need to migrate but it happened 😅 ) to proxmox. Just wanted to link to the

PowerShell for bash converts + pentesting goodies Note for the image... while it isn't directly correlated to the right kind of Windows, it is a peaceful picture. Normally I don't associate peacefulness with powershell, it is normally me fighting with the shell and it normally wins 🤕, so I am trying to

NOTE: the image for this blog post is because we are talking about something in the...shell... 😁️ I know that doing curl and directly pipe'ing into bash is considered a bad practice for security, and people discourage it. When it comes to automation though, sometimes there is no way to

So, I was curious about how I could push down a static route from my pfSense router (and it looks to also work for OpnSense as well under Services --> DHCPv4) to my work vlan for another network (my work's lab network (i.e. where some machines that I have
