Preventing 2FA Crises

Preventing 2FA Crises

Deleting versions from a Linode s3 bucket

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

disaster recovery to Proxmox

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

PS for bash converts

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

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

Lost without routing Sense

Lost without routing Sense
