Update!

This gist is out of date and I can no longer help much, as I got rid of my Mac.

Acknowledgements

This gist is just a compilation of the hard work that others have put in. I'm not a software developer, so if there are any mistakes or better ways of doing things, I'd appreciate any suggestions. Here's a list of the real heroes who made this possible:

Base64 Patterns - Learning Aid

Base64 Code	Mnemonic Aid	Decoded*	Description
`JAB`	🗣 Jabber	`$.`	Variable declaration (UTF-16), e.g. `JABlAG4AdgA` for `$env:`
`TVq`	📺 Television	`MZ`	MZ header
`SUVY`	🚙 SUV	`IEX`	PowerShell Invoke Expression
`SQBFAF`	🐣 Squab favorite	`I.E.`	PowerShell Invoke Expression (UTF-16)
`SQBuAH`	🐣 Squab uahhh	`I.n.`	PowerShell Invoke string (UTF-16) e.g. `Invoke-Mimikatz`
`PAA`	💪 "Pah!"	`<.`	Often used by Emotet (UTF-16)

Linux Kernel Modules for NixOS

You can find what kernel modules are loaded using lsmod.

However some kernel modules are required at stage 1 boot. Basically preloaded in the initial ram disk before switching to the root filesystem. These kernel modules are mostly needed to deal with peripherals, storage devices, filesystems and network devices. You may need to be wary of these required modules:

sd_mod - SCSI, SATA, and PATA (IDE) devices
