What’s up?

In this post we will learn how to secure our VPN so that it doesn’t leak any traffic.

If you have ever used a VPN for geolocation specific sites or applications, you might have run into the issue where your VPN turns off and suddenly you are connecting to that application using your main connection which can lead to minor interruptions from that site or application or even becoming blocked.

A solid setup can be the differential preventing this from happening and that is what we will learn how to configure in this post using some basic Windows firewall rules.

Let’s begin.

What’s up yall!

In this post we’ll take a look at Python for data recovery.

We’ll be covering a script I made that reads through a disk (in this example, a USB) and checks for specific file signatures in an attempt to recover photos and images (.jpg) from said disk.

If you haven’t seen my previous post about data recovery using a hex editor, I highly recommend it since a lot of the knowledge from that post will be automated using this script.

I’ll also get into how you can use this script to search for other types of files later on… 😉

Let’s get into the tutorial!

What’s good?

In this post we’ll see how to do data recovery using a hex editor.

If you used a data recovery program in the past you might have asked yourself: how do they work?

That is exactly what we’ll be covering on this post. I’m sure by the end of it you’ll have a broader understanding of what files look like in terms of raw bytes and how to identify them in a drive.

Let’s jump into it! 😉

In this post, we’ll check out file transfer in Python 3 with file size verification check.

In many Python scripts you’ll come across the need for sending and receiving files over the network, so I decided to make this tutorial for a simple yet stable set of scripts to implement whenever needed.

We’ll only use standard Python libraries included with a default installation: socket, time, os and sys.

One nice little detail we’ll implement is file size verification, so that the receiving party can be sure they received the file with the exact amount of bytes the sender intended.

Let’s check it out!

In this video we’ll dive into SQL injection for beginners using both automated tools and then replicating the process by hand so we can truly understand what is going on behind the curtains.

To further comprehend this vulnerability, we’ll also take a look at the code behind the web pages: both the PHP scripts and also the SQL statements to digest it properly.

SQL injection has been a heavy contender in OWASP’s top 10 vulnerabilities every year for over a decade at this point, so safe to say that its here to stay in current web apps and in the future.

Let’s begin by clarifying what exactly is SQL / code injection…
