Rust Cheat Sheet

Variables & Mutability

Variables are immutable by default. This makes Rust safer and makes concurrency easier.
Immutable means once a value is bound to that variable, it cannot be changed.
For example:

fn main() {
 let x = 5;

Time-Based Blind SQL Injection

Indication of a correct query is based on the time the query takes to complete.
This time delay is introduced by using built-in methods such as SLEEP(x) alongside the UNION statement.
The SLEEP() method will only ever get executed upon a successful UNION SELECT statement.

Base query example

/endpoint?query=admin123'

Attack query example

log4j RCE Exploitation Detection

You can use these commands and rules to search for exploitation attempts against log4j RCE vulnerability CVE-2021-44228

Grep / Zgrep

This command searches for exploitation attempts in uncompressed files in folder /var/log and all sub folders

sudo egrep -I -i -r '\$(\{|%7B)jndi:(ldap[s]?|rmi|dns|nis|iiop|corba|nds|http):/[^\n]+' /var/log

Turris

opkg install kmod-veth
opkg install kmod-ipt-extra
opkg install iptables-mod-extra

Install a new container (I created an arch linux container)
Open up the /srv/lxc/containername/config file for editing:

Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

Two native ports exist.

Improve Fonts

Newest

Make your Arch fonts beautiful easily! This is what I do when I install Arch Linux to improve the fonts.

You may consider the following settings to improve your fonts for system-wide usage without installing a patched font library packages (eg. Infinality):

Install some fonts, for example:
sudo pacman -S ttf-dejavu ttf-liberation noto-fonts

Docker on Android 🐋📱

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.
