I'm pretty sure that it's a universal dream for everyone in the world to retire early. Who wants to to be stuck with the rest of the country and retire when you're almost 70 years old? You heard me right, 70! Most people can't go out and do the things they love to do by the time they're 70, unless they've been practicing good health and exercise their entire life.
The already robust and ingenious Nmap tool has received a whole slew of new scanning scripts that can be used to do all sorts of naughty endeavors. Notably, the SQLi module, since it is a necessary evil that we must cover here at Null Byte. This major update is going to fuel today's lesson.
We're officially seeking Null Byters on a weekly basis who would enjoy taking their time to educate the community. Contributors will write tutorials, which will be featured on the Null Byte blog, as well as the front page of WonderHowTo (if up to par, of course). This is a job meant for anyone with the will to share knowledge. There is no need to be intimidated if you fear you lack the writing skills. I will edit your drafts if necessary and get them looking top-notch! You can write tutorials...
Today I will show you how to create a simple keylogger in Visual C# Sharp, which will start up hidden from view, and record anything the user types on the keybord, then save it into a text file. Great if you share a PC and want to track what someone else is writing.
The biggest struggle with flashing DVD drives on Xbox 360s has been the price tag of the probe to extract keys on some drives. The probe and kit is required to extract the DVD key, which is needed to perform a drive repair, flash, or backup of any kind. Who wants to pay big bucks for the "pro" kit and then get added to a huge waiting list behind a million other people looking to buy the same product? We can hack the same thing together at home!
Keyloggers are a must-have tool in your arsenal. Hardware keyloggers have the advantage of being undetectable through anti-virus or other protection programs. They also capture keystrokes before the OS even boots up, so they are pretty handy tools.
Reverse shells are useful for issuing commands to a remote client when the client is behind something such as a NAT. You might say, "But can't a normal shell or simple SSH tunnel do the same thing?". No, it can't. All over the internet I see a lot of confusion regarding the difference between a normal shell and a reverse shell. Let's clear this up before we get started.
I will not go into some time-waster of a story about how I came to build this app. It was a prerequisite in a bigger project I am still tinkering with from time to time.
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. They...
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.
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 the...
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's...
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.
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.
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.
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...
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.
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.
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.
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.
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.
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.
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...
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...
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.
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.
Ever since kernel 2.6.xx in Linux, a lot of the internet kernel modules for wireless interfaces became broken when accessing 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 suite, the software has become unusable.
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.
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.
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 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 and...
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...
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 machine...
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.
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 lower...
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...
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...
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...
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?
Anonymity is something that doesn't exist today. Everything you do in the world is tracked, from the purchases you make to surfing the internet—even taking pictures on your iPhone. Everything you have ever said and done on the internet is still there—somewhere. This is called caching. For example, when a site is down, you can view its cached page on Google.
When your computer first connects to a nework, it sends out a request on the network to lease an IP from the router. The router then leases your computer an unused IP address, which is used as a unique routing address for sending traffic that is meant for you, to you. As everything tends to, this method has its flaws.
When you first become interested in learning how to program, it can be difficult to find a place to start. A lot of questions come up, especially if you're new to the idea of programming entirely. After you pick which language you want to learn, you have to worry about how you're going to write the language.
Laptops are almost a necessity in today's society. It doesn't help that a laptop that can actually increase your work productivity will put at least a $1,500 dent in your wallet. I'm sure you have searched around to try to find factory direct deals, or (shiver) even looked at used laptops, but that isn't the way to go. You need something that actually has a warranty, and good performance, but at the same time, doesn't require you to sell a kidney. This can cause quite a dilemma, as it can take...
Backing up your files is a requirement in today's world of tech. In an instant, your storage device can fail. This is an unacceptable situation that should never happen to anyone. Storage is cheap, and backups are easier than ever to perform. Most of the time, this can be completely automated, so you can just set it and forget it. Today, Null Byte will be covering how we can automatically, and efficiently back up our data across all OS platforms, while giving a few alternatives to the built-in...
File Transfer Protocol, or FTP, is a network protocol made for transferring files in a client and host fashion over a Transmission Control Protocol (TCP) network, such as the internet. FTP is integrated into most browsers, and you have probably used it before. It is a common way to host files and transfer them easily. To access an FTP, a login is required, unless the server is configured to use anonymous logins (like the Arch Linux mirrors).
With the plethora of programming that we promote at Null Byte, I figured a lot of you newbies that stop by IRC will need a big boost in the right direction to make your dive into programming a lot easier. A hot question that has been thrown around in IRC a lot when making the initial dive is, "How do I write code?". People who do not know much about computers can't understand how code is written. Code that we write here is usually scripted and written in Python, so we will use it as our example...
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:
When Windows stores a password, it is done so by hashing the password in an LM hash and putting it in the Windows SAM file. In the scary moment that you lose your password, but don't want to pay some geek to have full root access to your computer, you need to recover it using Ophcrack. Ophcrack doesn't remove the password, or bypass it, it cracks the password hash using rainbow tables.
More password cracking action from Null Byte! Today we aren't going to be cracking passwords per se, rather, we are going to learn the basics of generating rainbow tables and how to use them. First, let's go over how passwords are stored and recovered.
Back when I was a Windows user, I know I'm not the only one who has experienced password loss—that moment where you just can't remember your password. Sometimes it happens to the best of us. So, how can we get into the system without paying a local geek or geeksquad to do it? First, we have to look into how Windows stores their passwords.
To the displeasure of many loyal Firefox users, Mozilla has been deploying what seems like a new marketing strategy to "catch up" to Google Chrome. I have no idea if this is because the version number is higher than theirs, but it is downright annoying. It's not all complaints, though. Firefox has done an amazing job at completely revamping its source code and redesigning all of its engines, making it a more than worthy competitor to Chrome. However, we are displeased with Firefox because...
As we all know, security is a big thing here in Null Byte. We've talked quite a bit about ways to encrypt traffic and become anonymous on the internet, some of which entail using proxies, VPNs, and SSH tunnels. We've also talked about preference using SSL pages in practice for safe logins. These are all great protocols and tools, but aren't without their flaws and inconveniences.
With the computer's rapid increases in power and efficiency, computer virtualization has taken the scene by storm. With virtualization software, and powerful enough computer hardware, your computer can run a virtual computer within itself. This effectively gives you multiple OS's on the host OS. This can be used for a lot of cool stuff that your computer would normally be limited by. Let's take a look at a few.
