AnarSec: Tech Guides for Anarchists

AnarSec is a new resource designed to help anarchists navigate the hostile terrain of technology — defensive guides for digital security and anonymity, as well as offensive guides for hacking. All guides are available in booklet format for printing and will be kept up to date.

As anarchists, we must defend ourselves against police and intelligence agencies that conduct targeted digital surveillance for the purposes of incrimination and network mapping. With the defensive series, our goal is to obscure the State’s visibility into our lives and projects. Our recommendations are intended for all anarchists, and they are accompanied by guides to put the advice into practice.

With the upcoming offensive series, we hope to contribute to the practice of hacking the State and capital. Astute readers may notice that the art featured on our homepage and booklets is taken from communiqués detailing how anarchists robbed a bank (Phineas Fisher) and destroyed police servers (AntiSec) using only a keyboard.

The defensive series currently includes:

Tails

Tails for Anarchists

Tails Best Practices

Qubes OS

Qubes OS for Anarchists

Phones

Kill the Cop in Your Pocket

GrapheneOS for Anarchists

General

Linux Essentials

Remove Identifying Metadata From Files

Encrypted Messaging for Anarchists

My First CTF (Capture the Flag)

I've never had any experience doing CTF's or using nmap, but today has been really fun as I continued to learn how to find flags using nmap. For this to be able to happen, I went on Hack The Box and started practicing on there.

My experience with this was actually quiet fascinating. I learned about port scanning through nmap and have picked up a skill in knowing how to use the Linux terminal and navigate through it. Today, two of my CTF's contained lessons about using nmap to find open ports for Telnet and FTP (File Transfer Protocol). I'll admit it took me a while to learn how to find the flags within those services but I found great enjoyment in it. To be honest, I want to do so much more as I develop these skills and learn how to use new tools. Doing this also has helped me stay off the phone for a bit because doom scrolling on Instagram or YouTube is really unhealthy.

As a beginner in this area, I highly encourage newcomers to get on Hack The Box if you want to learn how to use nmap, as it also gives you a step by step lessons on how to find the flags and teaches you what to look for, for your future use of nmap.

I felt like sharing this post today because I wanted to show the hacking community how excited I am learning these skills, and even though I haven't done as much and an experience hacker, I'm still proud of the work I've done. If there's any advice, or pointers that anyone is willing to give me, I'll gladly take it. Anyways, thank you for reading this post.

And as always, Godspeed everyone.

I need some help from people familiar with weird USB things

I got this weird android tablet I can't root/charge without this special M/M dongle I do not own

This pic from the manual suggests there's something going on specifically in the tablet side of the m/m usb cable

The tablet has a usb 3.0 connector on it, but all the extra data pins are disconnected except for the middle gnd pin, that has a 5 ohm resistance on it relative to the device's gnd.

I suspect there's some kind of USB OTG shenanigans going on here, where the gnd pin is being used as a USB OTG ID pin, but I can't be certain.

Whatever it's doing it would have to function like a normal usb 2.0 port when either a usb 3.0 device (ties gnd to gnd) or a usb 2.0 device is connected (Extra GND is floating) so I honestly have no clue how this would work unless it's measuring a particular resistance or something

Here are some pics I took of the motherboard

pro tip for programmers - how to alias

hey, so you know that annoying thing that happens when you're coding, and you need to run/test the same program 100 times in a row, so you end up typing "python3 testScriptWithASuperLongName.py" into the terminal about 80,000 times?

well, there's a better way! it's called aliasing :D

in your bash shell (or zsh, or whatever shell you use, but bash is the default on VSCode and most people on tumblr use VSCode, so I'm using bash as the default to explain this concept) you can set an alias, essentially a shortcut command, that runs longer commands.

(yes you can just use the up arrow key to re-run the same command, but sometimes you're typing other things into the terminal too and you don't feel like hitting the up arrow key four times in a row, and also this is just a cool and useful tip to get comfortable with aliasing so shhhh)

so, in your terminal shell, just type this:

alias run="python3 testScriptWithASuperLongName.py"

now, you can run that entire super long command, just by typing the word "run" into your terminal. Here's a screenshot of an example on my computer to make it make more sense:

in this example, i just created a simple python file that contains one line of code: print("it works!")

then, as you can see, by setting the alias to run, i can now run that file, runningatestscript.py, simply with the command 'run'.

the best part is, this alias is temporary - it only lasts as long as your shell session is open. so once you close the terminal, the run alias is cleared and you can set it again next time to any file or task you're currently working on, to save yourself a lot of typing, typos, and time.

so if you want to, you can get in the habit of always setting a run alias in the VSCode terminal for whichever file you're working with as soon as you get everything open. that way, when you need to run the same file 50 million times, you have a super easy way of doing it! you can even set it to a single letter if you want to go for maximum speed, but i prefer to use whole short words, because they're easy for me to remember.

note: if you do want to set an alias to work for all sessions, you can simply add it to your ./bashrc file. this is a common way to automate repeatable tasks, and simply to set easier-to-remember commands for terminal commands that are really complicated/confusing/hard to remember.

for example, i saved the alias checkboot="[ -d /sys/firmware/efi ] && echo 'UEFI mode' || 'BIOS mode'" into my zshrc file (zsh equivalent of bashrc file). this way, no matter how many times i rebooted my machine, i would always be able to quickly check which boot mode was running by simply typing 'checkboot'.

yesterday i was updating my boot mode from BIOS to UEFI on my very old machine that is technically compatible with UEFI, but not configured for it by default. So it was extremely helpful and saved me the time and headache of having to remember and type that long-ass command a thousand times in between many different reboots and new shells.

if you have any tasks like that, or terminal commands that you know would be useful to you, but you can never remember them when you need them, i highly recommend getting comfortable with aliasing! it can be super useful to simply set custom aliases for all the commands you don't want to remember, so that you can automate things away and not have to worry about so much linux syntax all the time when you're tring to focus on programming.

i know this may seem like a simple tip to some, but i only learned about it recently and it's been extremely helpful to integrate into my workflow and customize my OS with! so i thought it might be worthwhile to some people if i share :) hope it helps!
