For a moment, picture a situation where you want to host some files or images, but you do not want it traced back to you. Perhaps you're working on a project with others and need secure data storage. Anonymity is the new shield of the 21st century—and you best protect yourself ...more

File recovery on Linux is a bit different than Windows. It requires different software than the Windows counterparts because every OS has their own file system. Windows uses NTFS, or FAT file systems, while on the other hand, Linux uses ext-based file systems. I personally use ...more

If you remember last time, we successfully uploaded picture with a small hidden PHP command executer embedded in it onto a server. Now, our goal is to take this a step further and get an interactive shell. To do this, we need to upload another file that either binds a port for ...more

In this article, we will explore the basics of radare2, a powerful package that comes with Kali. We are going to write a simple program, and then disassemble it, to see what is really doing in the processor. I will use Kali version 1 and x86 (64 bits) instructions. Not all ar ...more

Welcome back, my budding hackers! One of the keys to being successful as a hacker, pentester, or cyber warrior is the ability to find vulnerabilities or flaws in the target system, which are what we exploit when we hack. We have looked at several ways to do that including var ...more

Hundreds of Windows 10, macOS, and Linux vulnerabilities are disclosed every single week, many of which elude mainstream attention. Most users aren't even aware that newly found exploits and vulnerabilities exist, nor that CVEs can be located by anyone in just a few clicks fro ...more

Here at Null Byte, we've spoken a lot about securing and anonymizing traffic. This is a big deal. With all of today's business taking place electronically via computers, we need to be secure when on-the-go. A lot of businesses don't even train their employees to secure their c ...more

The ESP32-CAM is a convenient little camera module with a lot of built-in power, and you can turn one into an inconspicuous spy camera to hide in any room. There's only one issue: it does omit a USB port. That makes it a little harder to program, but with an ESP32-based board, ...more

Complex shell scripts can be implanted into photo metadata and later used to exploit a MacBook. In addition to obfuscating the true nature of an attack, this technique can be used to evade network firewalls as well as vigilant sysadmins. In this attack scenario, a malicious c ...more

AppleScript is quite an easy scripting language to use. In this guide, I will be showing you several commands. Near the end, I will show how these can be used to create a fake virus that actually does no harm. Of course, this is only one way to use these commands—use your ima ...more

A lot of people still trust their web browsers to remember every online account password for them. If you're one of those users, you need to adopt a more secure way of managing passwords, because browser-stored passwords are hacker gold mines. With a USB Rubber Ducky and physi ...more

What if the code you are trying to reverse engineer is obfuscated or somehow corrupted? What if no way is left? Here comes what I like to call (wrongly and ironically) the "brute force of reverse engineering". Before I even start, as always, I wanted to apologize for any uncl ...more
