šŸ‘‹ Hi, I'm Alex!

I'm a Security and Cybersecurity professional with 5+ years of experience in Offensive Security, Physical and Digital Pentesting and Ethical Hacking. As a Red Team operator I have helped many networks and places become more secure.

I get excited about the challenge of getting into places (legally) I should not be able to. It doesn't matter if it's through hacking or lockpicking, I like to help people and companies improve their security.

About me...

  • šŸ” Freelance physical & digital pentester
  • :feelsgood: Former Special Forces Operator
  • šŸŽ¼ I love Heavy Metal
  • šŸ’» Used to be a web developer

esp8266-wifi-deauther icon esp8266-wifi-deauther

Today we're doing something different. We will leave the computer for a while and make something with our hands. Let's make the Wi-Fi Deauther from Spacehuhn. Check his Github, it's awesome all the stuff he makes!

fingerprinter icon fingerprinter

Fingerprinter is a simple Browser Fingerprinter built using HTML, CSS and JavaScript. I have based this project on FingerprintJS but adding some extra features out of the scope of browser fingerprinting as a PoC of how much data can be easily gathered from a client when visiting a website.

gc2 icon gc2

GC2 is a Command and Control application that allows an attacker to execute commands on the target machine using Google Sheet and exfiltrate data using Google Drive.

kioptrix1-walkthrough icon kioptrix1-walkthrough

Today we are hacking into a highly recommended beginner CTF called Kioptrix. I had some troubles installing the machine from VulnHub so, in case you face some errors, I am providing you the .OVA file for the vulnerable machine.

kioptrix2-walkthrough icon kioptrix2-walkthrough

Today I'm hacking into Kioptrix 1.1. Or Kioptrix #2. Whatever. This is one of the many beginner-friendly OSCP-like CTFs of Vulnhub. So it's a great starting point for preparing the OSCP tests.

lord-of-the-root-walkthrough icon lord-of-the-root-walkthrough

As a LOTR fan I decided to start my CTF documentations by documenting the process of hacking this VulnHub Machine called Lord Of The Root.

passman icon passman

#passman is a password generator and manager built using Python and SQLite3. It has a nice GUI made with customtkinter and it features a little mod of the ctk_optionmenu widget to add a placeholder text. You'll have to add this mod to be able to use it.

powersploit icon powersploit

PowerSploit - A PowerShell Post-Exploitation Framework

proxmark3-bulk-wrbl icon proxmark3-bulk-wrbl

Writing blocks with a Proxmark3 Easy can become an exhausting task when you need to write several blocks and the built-in function for restoring fails.

python-hacking-tools icon python-hacking-tools

These are all the python tools and scripts I have crafted so far. I will be updating the repo as I code more or if any update needs to be made.

red-team-book icon red-team-book

This repository contains cutting-edge open-source security notes and tools that will help you during your Red Team assessments.

secure-network-for-ctf icon secure-network-for-ctf

The process is quite easy but it allows you to run VulnHub machines without any risks. This way you can be safe while you hack into vulnerable machines as these machines won't be connected to the Internet.

sheller icon sheller

Sheller is a simple Online Reverse Shell Generator built using HTML, CSS and JavaScript. I have based this project on the amazing RevShells that supports way more languages and variants of all type of shells. I just wanted this project to be as simple as possible although Iā€™m thinking of adding more features.

tr0ll-walkthrough icon tr0ll-walkthrough

Today we are hacking into Tr0ll - a boot-to-root vulnerable machine. It's not a hard machine to hack into but it's a good one to learn new stuff and let the previous knowledge sink in.

wp-backdoor icon wp-backdoor

Many times I have asked myself how to maintain access to a compromised WordPress site for the sake of surveillance/data gathering/etc... Apart from reverse shells, of course, because I see some issues with the reverse shells stuff. That's why I posted this WordPress Backdoor.

wpyscan icon wpyscan

Like WPScan but UNLIMITED and FREE. A tool developed in Python for enumerating and scanning WordPress websites.
