How To: Code a Simple Java App to Kill Any Process After a Specified Time

I may be a bit weird, but I enjoy listening to music at night as I fall asleep. Sure, you could create a playlist of songs so that it stopped after all the songs finished playing, but I have a rather extensive database of music and I enjoy listening to them randomly. Also, I like to ensure it terminates after a specific amount of time (I don't want it playing all night). Or sometimes I use it when I am cooking so that when the music stops, I know I need to check on my food, etc.

How To: Fix Defective Pixels & Improve Image Quality on LCD & LED Monitors

I have owned quite the plethora of electronics in my life. A commonality between most of these devices' screens is frozen or dead pixels. This is probably the most annoying thing about buying new hardware—your LCD, or worse, LED display has one or more pixels that continues to stay lit. Most of the time, this will appear in the form of a brightly colored pixel that never changes, or a pixel that never displays the right color. Once you notice it's there, you just can't stop staring at it. It ...

How To: Take a Deep Dive into AI with This 4-Course Bundle

No longer strictly relegated to the realm of science fiction shows and novels, artificial intelligence can be found behind important technologies that are driving innovation throughout the world.

How To: Gather Information on PostgreSQL Databases with Metasploit

Attacks against databases have become one of the most popular and lucrative activities for hackers recently. New data breaches seem to be popping up every week, but even with all of that attention, databases continue to be a prime target. All of these attacks have to start somewhere, and we'll be exploring a variety of methods to gather information on PostgreSQL databases with Metasploit.

How To: Control Network Traffic with Evil Limiter to Throttle or Kick Off Devices

If you find yourself with a roommate hogging limited data bandwidth with video games or discover a neighbor has invited themselves into your Wi-Fi network, you can easily take back control of your internet access. Evil Limiter does this by letting you control the bit rate of any device on the same network as you, allowing you to slow or even stop data transfer speeds for them completely.

How To: Exploit EternalBlue on Windows Server with Metasploit

Particular vulnerabilities and exploits come along and make headlines with their catchy names and impressive potential for damage. EternalBlue is one of those exploits. Originally tied to the NSA, this zero-day exploited a flaw in the SMB protocol, affecting many Windows machines and wreaking havoc everywhere. Here, we will use EternalBlue to exploit SMB via Metasploit.

How To: Crack Shadow Hashes After Getting Root on a Linux System

After gaining access to a root account, the next order of business is using that power to do something more significant. If the user passwords on the system can be obtained and cracked, an attacker can use them to pivot to other machines if the login is the same across systems. There are two tried-and-true password cracking tools that can accomplish this: John the Ripper and Hashcat.

Mac for Hackers: How to Organize Your Tools by Pentest Stages

With all of the bare-bones setup out of the way in our Mac for Hackers series, your Apple machine should be ready to run a significant amount of pentesting tools. We can pull tools from GitHub and compile them, we can pull dependencies or tools from Homebrew, we have both Python and Ruby. Everything is ready to go and now it's time to start building a toolbox on our local host.

How To: Use UFONet

With the release of the Mirai source code, botnets are back in a big way. In the early days of botnets, zombies (infected hosts) would report to IRC (Internet Relay Chat) channels for CNC (command and control) instructions. Modern botnets have evolved, but they continue to use the same concepts as their predecessors.

How To: Use a Misconfigured SUID Bit to Escalate Privileges & Get Root

Gaining access to a system is always exciting, but where do you go from there? Root or bust. Sure, a compromised host is a great way to run a botnet, or do some other boring, nefarious thing—but as hackers, we want root. We also want to take the easiest path possible, search out low-hanging fruit, and exploit them. SUID programs are the lowest of the low-hanging fruit.

How To: Use Meterpeter on OS X

Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on OS X (it has several more commands/options), but I think it is still worth noting how to do it. I've even seen some people mistakenly say that Meterpreter can only be run on Windows, which is not true. Meterpreter can ea...

How To: Use Social Engineering to Hack Computers

Today I am going to teach the various ways that you can use social engineering to hack a system. For those of you that have followed my past tutorials, you know that social engineering can unlock a world of possibilities. This is because no matter how many firewalls, no matter how many patches there are on a server, the password is kept in the minds of people...and people, are not as smart as computers.

Hack Like a Pro: How to Hijack Software Updates to Install a Rootkit for Backdoor Access

Welcome back, my neophyte hackers! There are innumerable ways to hack a system. We must not overlook any of the possibilities if we want to "own" the system. As systems become more and more secure, we need to be vigilant in our search for weaknesses. In this hack, we'll look at abusing the trust that a user innately has for software updates to install our own listener/rootkit on their system.

Hack Like a Pro: How to Use Netcat, the Swiss Army Knife of Hacking Tools

For over 20 years, a tiny but mighty tool has been used by hackers for a wide range of activities. Although well known in hacking circles, Netcat is virtually unknown outside. It's so simple, powerful, and useful that many people within the IT community refer to it as the "Swiss Army knife of hacking tools." We'll look at the capabilities of Netcat and how the aspiring hacker can use it.

Steampunk Spray Painting: How to Make Almost Anything Look Like Metal

What I'm going to do in this tutorial is, as the title implies, teach you how to make nearly anything look like metal. This can especially come in handy in Steampunk, as most of us don't have the ability to machine brass. We do, however, have access to wood, PVC, and spray paint. Not to mention that, as a costumer, I can speak from personal experience when I say that things made of brass are really, really, really heavy!

How To: Stay as Anonymous as Possible Online

There are lots of people who want to stay anonymous online, and lots of reasons they want to do this. Staying anonymous on the internet isn't easy, and it's probably possible to trace almost anyone with enough time and resources. A lot of people think that they're completely secure with just one method of cover. For example, a lot of people thought anyone using the Tor network was nearly untraceable, but then things like this often cast doubt on just how secure these networks are. Unless you ...

How To: A Hitchhiker's Guide to the Internet: Today and Now, How It All Connects

In the first part of this series, we took a factual and technical look at the history of the Internet. I explained how all of these wires and servers got here in the first place. Obviously, a firm did not just create and build the Internet around 1995! Now that we know how the Internet came to be, we can get into the really fun stuff—what the Internet looks like now! Well, that's not quite the network design I was talking about, but it does show what the Internet looked like back in 2007 befo...
