How To: Build a Laser Trip Wire Alarm System
Building a DIY Alarm System: The Concept So, you want to protect your property, or maybe a room, car, or even your backyard. The concept of an alarm system is to notify the "alarm administrator" that there is an intruder entering the previously designated boundaries. The triggers for this boundary could be as simple as a pressure sensor, or as complicated as a laser network. They all do the same thing, but some work better than others.
How To: Remotely Control Computers Over VNC Securely with SSH
VNC is a great protocol that you can use on Windows and Linux machines to remotely control computers. This is useful if you need to control your computer when away from home, help your grandma check her email, or help a client with a disk cleanup. VNC is secure in the sense that it requires authentication in order to make the connection, but after that, the data is sent over the internet unencrypted. This means that an attacker could sniff your traffic and snoop everything that's going on. Th...
How To: crack password protection on Excel Spreadsheets
Hi again, Just wanted to share a neat little code that I found way back, when I was presented with a spreadsheet which was locked and asked to ''unlock'' it or do whatever it takes to enable the user to edit it's contents.
UDP Flooding: How to Kick a Local User Off the Network
Only so much data can be passed through the network and to your computer's networking interfaces. This is limited by the amount of bandwidth you have. The more bandwidth you have, the faster your network connections will be. Not only this, but your transfers will be more parallel and distributed so that all of your speed isn't taken up by one transfer. When all of your bandwidth is sapped and unable to be used, this is called a denial of service, or a DOS.

How To: The Hacks Behind Cracking, Part 2: How to Generate Software Keys
If you've ever heard software piracy terminology being discussed, I'm sure the term KeyGens came up. KeyGens is short for key generator, which is a program that exploits algorithmic faults in software by generating software license keys that appear to be genuine. Normally used as a technique to protect the source code software and prevent piracy, a key generator exploits the key algorithm to effectively nullify the need for any software licenses. For example, we must try to find patterns in t...
How To: The Hacks Behind Cracking, Part 1: How to Bypass Software Registration
If you've ever wondered how software pirates can take software and crack it time and time again, even with security in place, this small series is for you. Even with today's most advanced methods of defeating piracy in place, it is still relatively easy to crack almost any program in the world. This is mainly due to computer processes' ability to be completely manipulated by an assembly debugger. Using this, you can completely bypass the registration process by making it skip the application'...
How To: Get Your AMD Graphics, Sound & Other Drivers to Work in Linux on Your Laptop
With the purchase of my latest computer, installing Linux turned into a nightmare from Hell. The graphics drivers are probably the biggest issue that anyone with a newer computer will run into when installing Linux. AMD and NVIDIA are the dominant ones on the market, both of which have awful support.
How To: Hack WPA WiFi Passwords by Cracking the WPS PIN
A flaw in WPS, or WiFi Protected Setup, known about for over a year by TNS, was finally exploited with proof of concept code. Both TNS, the discoverers of the exploit and Stefan at .braindump have created their respective "reaver" and "wpscrack" programs to exploit the WPS vulnerability. From this exploit, the WPA password can be recovered almost instantly in plain-text once the attack on the access point WPS is initiated, which normally takes 2-10 hours (depending on which program you use).
How To: Run a Free Web Server From Home on Windows or Linux with Apache
Paying for web hosting isn't ideal in most situations. If you have your own website, hosting it yourself is very acceptable and easy to do, assuming your internet bandwidth permits. Most people want to run a personal site, nothing crazy, so hosting from home on low-bandwidth internet is actually a better solution in most cases.
How To: Turn Your House Lights On & Off Using the Internet
Haven't you ever wanted to live in a futuristic home? I think that homes are headed towards an era where they will be controlled by our computers and smartphones. No longer will you have to find your keys to unlock your door, or wait until you get home to monitor your security, because X10 is here.
How To: Get Free Netflix for Life
Null Byte is looking for moderators! In today's Null Byte, we're hacking Netflix. As most of you know, Netflix is a subscription service that streams movies and TV shows to your devices over the internet. A common stance amongst my Xbox Live friends is that Netflix isn't worth the cost. The instant movies predominantly consist of old titles, and new movies aren't added often enough.
How To: Hack a Radio to Pick Up Different Frequencies - Including Law Enforcement & More
Hardware hacks are something I feel we don't get enough of at Null Byte, so today I figured I would introduce a fun one. I've always been a curious hardware hacker. Taking things apart and learning how their internals work has always been a part of my nature. Quite some years ago, my father showed me a really cool trick on how to hack normal radios to scan frequencies that are normally non-listenable. This little hack allowed us to scan frequencies belonging to law enforcement, and even frequ...
How To: Hack Coin-Operated Laudromat Machines for Free Wash & Dry Cycles
Most people have had the unfortunate experience of not having a washer and dryer at some point. Apartments in my area tend to charge at least one hundred dollars extra for the units with washer and dryer hookups, and even more if you want a unit with an actual washer and dryer installed already. If you are young and just starting out, this may be hard for you to manage with your current salary. If you have no washer and dryer, the only alternative is the laundromat.
How To: Social Engineer Your Debt Collectors Into Giving You More Time to Pay Bills
Having bills to pay is one of the worst parts of life, especially around the holidays. And if you're extremely unlucky, you might also have to pay some hefty medical bills. This can put a heavy damper on plans, wants and needs. What's worse? The people that you owe money to are pushy and always bother you to pay in a more timely fashion, or worse, pay bigger premiums.
How To: Your Guide to Buying Computer Parts: How to Get the Most for Your Money
When you buy computer parts, it can be a tough decision where you want to put all of your hard earned dollars into. Not only that, but when you buy a top of the line component, 3 months later (at most), your hardware will likely be outdated. This puts consumers like us in a bit of a pickle when it comes to purchasing, especially on a tight budget.
How To: How Credit Card Algorithms Work: The Anatomy of Credit Card Numbers
Have you ever wondered how credit card numbers work? I mean, how they really work? How do they come up with the numbers? Credit cards actually follow a very specific pattern. Let's take a look at how they're set up.
How To: Downgrade and Jailbreak Your iOS Devices Stock Firmware for the Holidays
Lots of people are going to be getting the latest iOS devices this holiday season. But what good is a portable device if you don't hack it? Jailbreaking on the latest stock iOS, version 4.3.5, is a bit of a trivial endeavor. Not many people know how to downgrade from this firmware to a firmware that can be jailbroken (pre-iOS 5). If you want the added functionality and the complete control over your device that comes with jailbreaking, then read on.
How To: Install an Off-the-Shelf Hard Drive in an Xbox 360 (Get 10x the GB for Your Money)
Since the day of the Xbox 360 release, storage space for the device has been overpriced beyond belief. OEM 250GB HDD models still cost $110 USD! A 250GB hard drive should not destroy my wallet, Microsoft. Storage space, especially on HDDs, is cheap. You can buy a removable 2TB external for only $100 USD, so it's a little beyond my comprehension to see how they calculate their MSRP to yield such a large profit. On the other hand, Xbox 360 had very impressive hardware specs back in the day, equ...
How To: Get Unlimited Money in Skyrim by Hacking Your Game Saves
Skyrim is a time consuming game. I know I'm not alone in saying I constantly find myself looking for more time in the day. There is never enough time to read the books I want to read, or learn what I want to learn, or play the games that I want to play.
How To: Defend from Keyloggers in Firefox with Keystroke Encryption
Null Byte is looking for moderators. More threats to computers exist every day. Not only do we have computer viruses and malware, but we have rootkits and other nasty pieces of code that can log your keyboard strokes or even add your computer to a botnet to attack other websites. Your computer can be infected even if you have anti-virus software installed. I can't stress enough how easy it is for a hacker to write a piece of code that gets around every piece of anti-virus software.
How To: Hack Your Xbox Gamerscore
Nearly everyone has the capacity to be a cheater. Sometime or another, all Xbox users have yearned to get their gamerscore to unimaginable thresholds—for bragging and egotistical purposes. I can relate to this desire. However, I also don't want to mod my gamerscore, because it's just unfair and not nearly as much fun as doing it the honest way. To me, it's synonymous to entering the cheats into a game after you've beaten it. Cheats can add new life into a game once you're done, but since the ...
How To: Copy & Convert your Skyrim Game Save from the Xbox 360 to your PC
Gamers like myself who have switched back and forth between Skyrim on PC and Xbox lack the ability to share game saves. This really sucks. I love playing Skyrim on a console. It's a very comfortable, easy and relaxed gaming experience. You don't have to worry about your frame rate being optimized, or wrist pains from using a keyboard. However, gaming on the PC can allow you to use texture enhancing mods and get an overall smoother experience due to a lack in glitches and bugs that plague the ...
How To: Windows 7 Won't Boot? Here's How To Fix Your Master Boot Record
With a lot of Null Byters playing around with Linux because of its excessive use in the hacking world, some of you are bound to run into some trouble with the installation at some point or another. If you make a mistake, or you're intimidated by the wonky-looking installation screen, you may want to just stick with Windows. However, you may notice it can be hard to go back once you've crossed a certain point in the installation. Your Windows installation may be broken or unbootable.
How To: The Novice Guide to Teaching Yourself How to Program (Learning Resources Included)
Today's post is a small go-to guide for beginner programmers in Null Byte. With many of our community members picking up programming from our Community Bytes, it only makes sense to lay out a one-stop guide for your reference. Hopefully this guide will help you make an educated and thoughtful choice on what programming languages you want to learn, and how you want to learn said languages.
How To: Fix the Channel -1 Glitch in Airodump on the Latest Kernel
Ever since kernel 2.6.xx in Linux, a lot of the internet kernel modules for wireless interfaces ended up becoming broken when trying to use monitor mode. What happens commonly (to myself included) is a forced channel that your card sits on. No good! For users of airodump and the aircrack-ng software suite, the software has become unusable.
How To: Fix the Unreadable USB Glitch in VirtualBox
Many users of the virtualization software VirtualBox may have noticed that the USB system has been pretty buggy for quite a long time. I've had my USB randomly duck out on me way too many times to count. This can really be difficult to deal with when you require access to the devices and files from the host system.
How To: Install Linux to a Thumb Drive
Let's face it, CDs and DVDs are a thing of the past. We no longer use them as a storage medium because they are slow, prone to failure in burning, and non-reusable. The future is flash memory. Flash memory is cheap, fast, and efficient. Eventually, flash drives might even replace discs as the preferred prerecorded selling format for movies.
How to Hack Your Game Saves: A Basic Guide to Hex Editing
The days of entering left, right, left, right, up, down, up, down, a, b to cheat your way through a video game are long gone. With achievements and trophies in existence, game developers have, for the most part, removed cheats from video games.
How To: Make Skyrim (& Other Games) Utilize AMD Crossfire Before the Patch is Released
Users of the latest AMD 6xxx series graphics cards may have noticed that when they are playing Skyrim, their framerate isn't anywhere near what it is supposed to be with dual GPUs in Crossfire. AMD is working on releasing drivers with these issues fixed, but it has been too long since Skyrim has come out to just sit and wait.
How To: GPU Accelerate Cracking Passwords with Hashcat
How to Crack Passwords Faster by Putting Your GPU to Work with HashcatSecurity on the internet is always changing. Not too long ago, having a 10 character password meant that you were safe from all forms of hash cracking. Hash cracking is when you take a string of characters that have been passed through a cryptographic hash and try to reverse them. The normal processors that are housed inside of our computer cases are general purpose. The processors are not meant for handling complex math an...
How To: Fix a Bricked iPhone or iPod Touch After a Failed Jailbreak
I can't believe it, but I've actually read about dozens of people getting their iTouch, iPhone, or iPad stuck in a bricked recovery loop and then going out to buy a new one. This is overly unnecessary. When it gets stuck in the recovery loop, some people mistake themselves by thinking that it is impossible to get the device back into DFU (Device Firmware Upgrade) mode. Getting the device back into DFU mode would at least allow us to jailbreak the device, essentially bringing it back from its ...
How To: Safely Overclock Your GPU, CPU & RAM for Better Speed & Performance
Overclocking is quite an awesome thing. When computer components are designed, they are made to run at a certain speed, otherwise known as their clock and bus speeds. These limits are not actually limits. You can overclock components, which essentially makes them go faster than their set limitations. This can save you a lot of cash when newer components come out and you don't have enough money to upgrade. However, when you overclock components, you must be careful and make sure that the machi...
How To: Proof of Social Engineering Success!
Just showing off the successful social engineering results. Make sure that if you used the guide, post back here with a picture of whatever you bought!
How To: Shorten URLs from the Command Line with Python
Shortening URLs has become a necessity in this age of Twitter and limited-character status updates. It not only allows us to cram more words into our oh-so-important Twitter statuses, but it also helps us with a few other things.
How To: Social Engineer Your Way Into an Amusement Park for Free
When it comes to social engineering, Null Byte is here to show you how it's done. Social engineering is the key fundamental to unlocking tons of possibilities and opportunities in your everyday life. So, what is social engineering? Social engineering can be called many things. It's taking nothing and turning it into something. It's taking the bad and making it good. Above everything else, it's the art of manipulating the world and people around you—coercing that salesman into giving you a low...
How To: Create a Free SSH Account on Shellmix to Use as a Webhost & More
Having an SSH or Secure SHell to tunnel your traffic through is something we have talked about many times at Null Byte. As we know, it allows us to securely route and encrypt our traffic through a remote server, effectively anonymizing us and protecting our traffic from all forms of analysis—simultaneously. We have gone over how to make a home SSH tunnel. However, the question has come up, "How can I get an SSH tunnel to somewhere other than my computer?" This would be useful in a situation w...
How To: Backup All of Your Xbox 360 Data to Your Computer
Flash memory can be a tad unpredictable at times. I have had 4 flash drives die out on me over the last few years, and they usually die without warning. When a flash memory based device dies, the data is likely impossible to recover. Adversely on an HDD, or Hard Drive Disk, even if the disk dies out, someone will probably be able to fix it and get it back to working order—at least long enough for you to back up your data. Hard drives are a bit more forgiving. As you can guess, due to the unpr...
How To: Code Your Own Twitter Client in Python Using OAuth
This is my attempt to show people some cool things we can do with programming, and to give a small incentive for people to join the weekly Community Bytes. I wanted to make a tutorial on how to use Twitter from the command line with Python. This would have been an easy project to do not too far back, and a good bit of practice for a beginner to programming. It teaches that you can do useful stuff with programming. However, a while ago Twitter started using something called OAuth to access the...
How To: Encrypt your Skype Messages to Thwart Snooping Eyes Using Pidgin
Skype is a great service. It allows a free solution for VoIP to VoIP calls, and cheap VoIP to landline calling. However, a very disturbing, little known fact that might push you away from Skype does exist. If you closely read the terms of service agreement, it clearly says that Skype is allowed to decrypt your messages whenever they please. Here at Null Byte, we tend to enjoy our anonymity, don't we?
