Welcome back my, tenderfoot hackers! Many people come to Null Byte looking to hack Facebook without the requisite skills to do so. Facebook is far from unhackable, but to do so, you will need some skills, and skill development is what Null Byte is all about.
Very often we have processes in Linux that we want to always run in the background at startup. These would be processes that we need to start at bootup and always be available to us.
Hello fellow gray hat hackers, I wrote a program in python that helps me to fill up my proxychains.conf file, so I don't have to manually enter in the proxies. I figured I will give a little how-to of how I did it and maybe I could help some of you(hackers) out there to stay anonymous.
Welcome back, my greenhorn hackers! The Holy Grail of any hacker is to develop a zero-day exploit—an exploit that has never been seen by antivirus (AV) and other software developers, as well as intrusion detection system (IDS) developers. In that way, you can exploit systems with your newly discovered vulnerability with impunity!
Hello fellow Null-Byters! In this "tutorial" we will be going basics of HTML. In the next tutorial, we will be going over CSS and then apply JavaScript.
Welcome back, my novice hackers! More and more, the world is turning to and adopting the smartphone platform as the digital device of choice. People are not only using smartphones for voice communication, but also web services, email, SMS, chatting, social networking, photography, payment services, and so on.
If you have never heard of a Virtual Machine (VM) before you might think it to be some new kind of gamers virtual reality system, and that would be incorrect. A virtual machine is a Virtually a real computer that exists inside of your own computer. You can run Kali inside of a Windows environment via your VM. Not quite the same as an actor portraying an actor on TV. A virtual machine will have it's own IP address and you have the ability to network to it from your Real (Host) computer and bac...
If you ever need to make calls and/or send texts to the U.S. or Canada from abroad, or even just receive them from those locations, there's an easy way to do so without breaking the bank. In fact, it's free, and all you need is a smartphone, computer, and some free tools.
Amazon thinks that by simply removing an app from their Appstore, that they will stop users from accessing it. But with Android OS powering their Fire TV Stick and Fire TV, there really isn't anything they can do to prevent us from sideloading an APK onto the streaming media devices.
Welcome back, my greenhorn hackers! Many new hackers come from a Windows background, but seldom, if ever, use its built-in command-line tools. As a hacker, you will often be forced to control the target system using just Windows commands and no GUI.
Welcome back, my hacker novitiates! There are many ways to hack databases, and most of these techniques require SQL injection (SQLi), which is a way of sending SQL commands back to the database from a web form or other input. In this tutorial, we will use SQL injection to get access to the underlying server. So instead of getting access to the database and its data, we will use the database as an intermediary to gain access to the underlying server.
WPA Enterprise is widely used in large corporations as it offers individual and centralized control through a server that authenticate the users (RADIUS server). In this tutorial I will show you how to break the barrier and obtain the user credentials.
In the last iteration of how to train your python, we covered basic string manipulation and how we can use it to better evaluate user input. So, today we'll be covering how to take user input. User input is very important to scripting. How can we do what the user says if we can't tell what the user wants? There are multiple ways to take input, we can give the user a prompt and take input from them directly, or we could use flags/switches, and take their input before the script is even execute...
Mostly all hackers like to have a laugh. We like to have fun! We like to troll. And maybe, even cause some havoc once in a while. But, while we do this, we must always stay in the line of the law.
Well hello dear readers of Null byte, let me start off stating english is not my first language and they will be some grammar mistakes. This also is my first tutorial so don't hesitate to give me feedback :)
Welcome back, my tenderfoot hackers! A number of you have written me telling me how much you enjoy the Mr. Robot series on USA Network. I am also a huge fan! If you haven't seen it yet, you should. It may be the best show on TV right now.
I'm sure that many of us have heard of that nasty Shellshock vulnerability, but not very many people know how to exploit it. Try these few tricks on vulnerable websites!
At last, what you all finally waited for! Hi! Fire Crackers,
Welcome back, my rookie hackers! In my ongoing attempts to familiarize aspiring hackers with Linux (nearly all hacking is done with Linux, and here's why every hacker should know and use it), I want to address a rather obscure, but powerful process. There is one super process that is called inetd or xinetd or rlinetd. I know, I know... that's confusing, but bear with me.
Welcome back, my tenderfoot hackers! A short while ago, I started a new series called "How to Spy on Anyone." The idea behind this series is that computer hacking is increasingly being used in espionage and cyber warfare, as well as by private detectives and law enforcement to solve cases. I am trying to demonstrate, in this series, ways that hacking is being used in these professions. For those of you who are training for those careers, I dedicate this series.
Welcome back, my novice hackers! This is the third installment of my Python scripting series. If you haven't read the previous two articles, take some time now to go back and read Part 1 and Part 2 before you proceed here.
Welcome back, my hacker novitiates! Eluding and evading antivirus software and intrusion detection systems is one of the most critical tasks of the hacker. As soon as a new exploit is developed and discovered, the AV and IDS developers build a signature for the attack, which is then likely to be detected and prevented.
Welcome back, my hacker novitiates! As you know by now, the Metasploit Framework is one of my favorite hacking tools. It is capable of embedding code into a remote system and controlling it, scanning systems for recon, and fuzzing systems to find buffer overflows. Plus, all of this can be integrated into Rapid7's excellent vulnerability scanner Nexpose.
Welcome back, my tenderfoot hackers! Those of you who have been reading my posts here for awhile know how much I emphasize good reconnaissance. Novice hackers often jump into a hack/exploit without doing proper recon and either fail or get caught. Experienced and expert hackers know that 70-80 percent of a good and successful hack is dependent upon successful and accurate reconnaissance.
Welcome back, my aspiring hackers! Those of you who use Windows in a LAN environment understand that Windows machines can share directories, files, printers, etc. using "shares." This protocol dates back to the 1980s when the then dominant computer firm, IBM, developed a way for computers to communicate over the LAN by just using computer names rather than MAC or IP addresses.
We've already seen the visual changes that Android 5.0 Lollipop has brought to the table, but Google spent just as much time altering things under the hood. Awesome new functionality and hardware capabilities have been added left and right, and with the OS already out now, it's high time we had a look at some of these tweaks.
What if someone asks you to do a Nmap scan but you left your pc at home? What if a golden opportunity shows during a pentest but you were walking around the building, taking a break?
Welcome back, my novice hackers! It has become clear from some of your questions that quite a few of you are unfamiliar with the hexadecimal system, or simply, hex. The hexadecimal system is used throughout computing and if you have never studied this Base16 numering system, it may appear relatively opaque.
Welcome back, my budding hackers! We've spent a lot of time learning to compromise Windows systems, and we've successfully compromised them with Metasploit, cracked their passwords, and hacked their Wi-Fi. However, very little time was spent developing ways to extract the information from the system once inside.
Welcome back, my tenderfoot hackers! We have looked at a number of ways that we sniff traffic on the network with such tools as Wireshark, tcpdump, dnsiff, and others, but each of these tools is only capable of pulling packets off the wire.
Welcome back, my greenhorn hackers! In my continuing effort to demonstrate to you how to hack the ubiquitous Windows 7, we will going after that notoriously vulnerable Adobe Flash that is on nearly every client Windows system (you are not likely to find it on servers).
The Samsung Galaxy S5 was just officially announced at Mobile World Congress. The new flagship device will be available worldwide beginning April 11, 2014, including all major U.S. and international carriers. With over 200 million Galaxy devices sold to date, the S5 doesn't stray too far from the trend, at least not aesthetically. We've still got a high-grade plastic shell with perforated back covers, and four color choices at launch. Our highlights of the release event are as follows.
Welcome back, my budding hackers! In my continuing effort to build your basic Linux skills for hacking, I want to show you how to build a secure "tunnel" to MySQL.
Welcome back, my greenhorn hackers! After the disaster that was Windows Vista and the limited and reluctant adoption of Windows 8 and 8.1, Windows 7 has become the de facto standard operating system on the desktop/client.
Welcome back My sleepless army of young hackers, Everyone uses internet, right? So for this tutorial, i'll start with the basics and slowly we'll get to the UPD Protocol.
Welcome back, my fledgling hackers! Awhile back, I demonstrated one of my favorite little tools, netcat, which enables us to create a connection between any two machines and transfer files or spawn a command shell for "owning" the system. Despite the beauty and elegance of this little tool, it has one major drawback—the transfers between the computers can be detected by security devices such as firewalls and an intrusion detection system (IDS).
Welcome back, my rookie hackers! When Wi-Fi was first developed and popularized in the late '90s, security was not a major concern. Unlike wired connections, anyone could simply connect to a Wi-Fi access point (AP) and steal bandwidth, or worse—sniff the traffic.
Welcome back, my nascent Hackers! In my last blog, we looked at a passive way to gather information necessary for a hack. The advantage of using passive recon is that it's totally undetectable, meaning that the target never knows you're scouting them and you leave no tracks. The disadvantage, of course, is that it's limited to only some websites and not entirely reliable.
Welcome back , my fledgling hackers! Lately, I've been focusing more on client-side hacks. While web servers, database servers, and file servers have garnered increased protection, the client-side remains extremely vulnerable, and there is much to teach. This time, we'll look at inserting a listener (rootkit) inside a PDF file, exploiting a vulnerability in Adobe's Reader.
When I left off on our last hack, we had hacked into the ubiquitous Windows Server 2003 server by adding ourselves as a user to that system so that we can return undetected at any time. The problem with this approach is that a sysadmin who is on their toes will note that a new user has been added and will begin to take preventative action.
