Getting Full Access to an Operating System
This tutorial will teach you how to get full access to a computer's filesystem. Physical access is required. This will work on 99% of computers. Basically what we're going to be doing is booting the computer into our own operating system and then accessing the hard drive that has the original OS.
TLDR;
There is no tldr
1. Make a bootable USB
The first thing we'll need is a USB flash drive. It should be at least 8 GB or so in size preferably. Next we need an alternate Linux OS to boot. I prefer Arch Linux for this type of thing because it's a minimal system and will boot up fast. When choosing your OS, you have to know the architecture of the machine you'll be attacking. If you don't know then usually 64-bit (x86_64) is a good bet. Older hardware may be 32-bit (x86) though. If you're going in blind you can just make a bootable USB for each. Go to hxxp://archlinux.org/download and look under the section called "HTTP direct downloads." Pick one one of the mirrors close to you. For example if you're in the UK, pick one of the links under the UK section. It should take you to a page with a bunch of files for download. Pick one of the ones that says something like archlinux-2020.x.x-x86_64.iso. Make sure you get a .iso file. It's a pretty small file, so it shouldn't take long to download. This is the file that we'll write to the USB and will function as our OS.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Next, we have to get software to write the image to the disk. If you know how, you could also use the command line tool 'dd', but if you don't know what you're doing you'll screw up your OS. Since we don't want you to screw up your OS, we're going to hxxp://balena.io/etcher. Download the appropriate version for your platform. The website should automatically pick the right version for you. Go ahead and install it. If it's not already inserted, put your USB drive into your computer. Keep in mind that putting the OS onto this USB drive will destroy ALL data previously on the USB. Start up etcher. You need to provide it with two things. The image file and the drive to write to. For the image file, choose the file you downloaded earlier. The drive should be the USB drive you have inserted in your computer. Now click the "Flash" button. This is the part that could take a minute or two at least. Go grab a snack or some coffee. Once etcher says it's done, you can take the USB out.
2. The Attack
The hard part is behind us now. You can test out the USB on your computer if you want. Turn your computer off. Now put the USB drive into the computer. We need to boot to the USB. Google how to boot from a USB with your hardware. Something like "boot usb <insert your hardware name>." Go ahead and follow the instructions to boot to a USB drive. When presented with the different boot options (there should be 2 or so), choose the USB drive. It should boot into the Linux OS and from there you can access the computers main OS hard drive. If you want a tutorial on the things you can do from there, let me know.
