My First PANDA

Introduction

Being someone who tries to play a lot with Windows memory, I really wanted to play with PANDA, but I was slightly scared because I'd never touched qemu before - all my experience had been with VirtualBox and VMware.

My goal was to install PANDA into a (relatively) clean install of Debian 8 'Jessie', capture a recording and successfully run a PANDA plugin.

Python zipapp web apps

What's a zipapp?

This concept is very much like .jar or .war archives in Java.

NOTE: The built .pyz zipapp can run on both Python 2 & 3 but you can only build .pyz zipapps with Python 3.5 or later.

Initial setup

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

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
