How To: The Essential Newbie's Guide to SQL Injections and Manipulating Data in a MySQL Database

No doubt you've seen some of the hack logs being released. One part that stands out over and over again is the heavy database usage. It used to be early on that virus and hackers would destroy data, usually just for lulz. However, with the explosive commercial growth of the Internet, the real target is turning into data theft. You should learn how this happens so you can protect yourself accordingly. Let's take a look at what makes this possible and dare I say, easy.

How to Pick Locks: Unlocking Pin and Tumbler Deadbolts

Lock picking is defined by locksmiths as "the art of opening a lock without the key". There's many ways to accomplish this, but I'm specifically interested in using a lock pick set. Since locks vary in shapes and size, it's better to stick with just one kind of lock at first. Most locks are based on fairly similar concepts, so sharing methods across locks is possible.

How To: Send SMS Messages with Python

In this article, I'll show you how to send SMS messages with Python. You'll need Python 2.7 or later, urllib and urllib2. The code basically uses an online text messaging service to "POST" html data, as if a person was entering the data themselves. The uses for something like this are unlimited. For example, I modified the basic code so I would receive a text message letting me know every time someone rang my doorbell. The program could interface with Arduino through a serial port, and send d...

How To: Encrypt And Decrypt Text In Python

In this article, I'll show you how to create a simplistic AES python based text encryptor. You'll need python 2.7 and PyCrypto (found here). The code is fairly simple, a user enters an encryption key (which basically tells the program how to scramble the text, using an algorithm), then the text to be encrypted. The program takes the key and text and inputs it into the "cryptograph" or code-based algorithm from PyCrypto. PyCrypto can use 16, 24, or 36 character encryption keys, but for the sak...

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: 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: 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: Use Wireshark to Steal Your Own Local Passwords

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 computers to protect from various threats. Here are a few things that should always happen when doing business on computers:

How To: Permanently Delete Files to Protect Privacy and Passwords

Permanently deleting files is something that a lot of people aren't aware of. Actually, most people think that once a file is deleted, it is gone forever. This is not the case. Hard drives write to the disk via magnetic charges, positive and negative correlate to 1s and 0s for binary. This is then interpreted into information for the computer to use and access.

How To: Give Your GRand Unified Bootloader a Custom Theme

GRUB, or the GRand Unified Bootloader, is a program that installs to your Master Boot Record and controls what operating system you load at boot time. Normally, it is used for multi-boot systems. Multi-boots allow you to switch between operating systems installed on seperate drives, or partitions at boot time. Linux actually uses it as its default bootloader, even without multiple operating systems.

How To: Make an Unbreakable Linux Password Using a SHA-2 Hash Algorithm

In Linux, all password hashes are normally stored using the MD5 hashing algorithm in the /etc/shadow file, but MD5 is algorithmically weak due to collision vulnerabilities. The new recommended standard are the higher level SHA-2 hashing algorithms, SHA256 or SHA512. As a friend pointed out to me, Ubuntu is currently the only distro implementing SHA-2 as the default. With SHA-2, your passwords take an unreasonably larger amount of time to calculate. This will greatly decrease how many password...

How To: Get Free Wi-Fi from Hotels & More

Often times when staying at a hotel or anywhere for that matter, you'll whip out your laptop and check the local area for Wi-Fi. I know you've all been in my shoes when you find an unsecured network that appears to be public Wi-Fi belonging to the hotel or airport, and you connect to it. You connect fast and perfectly, only to find that when you open your browser, it says you don't have an account, and are filtered from accessing the web. This is because the owners of the network want to keep...

How To: Run Windows from Inside Linux

Something that can shy a user away from making the switch to Linux is not having the option to go back to Windows. Luckily, there are solutions like dual-booting, where you can have both OS's installed right next to each other. However, Windows 8 appears as if it will block dual-boots with its neo-space BIOS that have been developed. Sneaky-sneaky. Windows users could still throw in a Linux live CD to try out Linux, but what does a Linux user do when they need something from Windows?

How To: Mine Bitcoin and Make Money

Bitcoin is a new currency built off "Satoshi Nakamoto's" (alias) 2008 Bitcoin white-paper. Bitcoin provides its users with a way to make peer-to-peer (P2P) transactions without having to use a bank as a mediator. There is no middle man, no corporation backing it, and no one has access to your money, except you. It's decentralized from government, run by the people, for the people.
