When we hack a web server, we usually want to be able to control it in order to download files or further exploit it. There are many websites that let you upload files such as avatar pictures that don't take the proper security measures. In this series, I will be showing you how to gain root access to such a web server.
Your IP (Internet Protocol) address is your unique ID on the internet. It's synonymous with your home address. Anyone in the world can contact your computer through its IP address, and send a retrieve information with it.
Hack Like a Pro: Python Scripting for the Aspiring Hacker, Part 3 (Building an FTP Password Cracker)
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 greenhorn hackers!
Welcome back, my hacker trainees! A number of you have written me regarding which operating system is best for hacking. I'll start by saying that nearly every professional and expert hacker uses Linux or Unix. Although some hacks can be done with Windows and Mac OS, nearly all of the hacking tools are developed specifically for Linux. There are some exceptions, though, including software like Cain and Abel, Havij, Zenmap, and Metasploit that are developed or ported for Windows.
Welcome back, my tenderfoot hackers! I have written many tutorials on hacking using Metasploit, including leaving no evidence behind and exploring the inner architecture. Also, there are my Metasploit cheat sheets for commands and hacking scripts.
Welcome back, my hacker novitiates! Many of you have probably heard of a man-in-the-middle attack and wondered how difficult an attack like that would be. For those of you who've never heard of one, it's simply where we, the hacker, place ourselves between the victim and the server and send and receive all the communication between the two.
Welcome back, my rookie hackers! As most of you know, Mr. Robot is probably the best hacker TV show ever! This is a great show about a cyber security engineer who is being enticed to hack the very corporation he's being paid to protect. This show is so good, I began a series to demonstrate how to do the hacks he uses in the show.
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.
Hello Elite Hackers! Welcome to my 3rd Post, which explains how to hack any account like G-mail, Facebook, etc.
How To: Create a Reverse Shell to Remotely Execute Root Commands Over Any Open Port Using NetCat or BASH
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.
Hi everyone! This is my first How To. Before we start you need to have a Facebook account (of course) and...this only works with your Facebook friends (so if you're looking for someone's mail on Facebook but you're not friends this won't work)
Welcome back, my greenhorn hackers! Before we attempt to exploit any target, it is wise to do proper reconnaissance. Without doing reconnaissance, you will likely be wasting your time and energy as well as risking your freedom. In previous guides, I have demonstrated multiple ways to perform reconnaissance including passive recon with Netcraft, active recon with Nmap or hping3, recon by exploiting DNS or SNMP, and many others.
OpenVPN is the open-source VPN (Virtual Private Network) client, used over the PPTP (Point to Point Tunneling Protocol). It allows you to connect to a remote network over a secure, encrypted connection and mask your IP addresses over all ports. Since there is only one "hop," the network speeds are barely effected and are far more secure.
Welcome back, my tenderfoot hackers! Not too long ago, I showed how to find various online devices using Shodan. As you remember, Shodan is a different type of search engine. Instead of indexing the content of websites, it pulls the banner of web servers on all types of online devices and then indexes the content of those banners.
Welcome back, my fledgling hackers! In the first part of my series on Wi-Fi hacking, we discussed the basic terms and technologies associated with Wi-Fi. Now that you have a firm grip on what Wi-Fi is exactly and how it works, we can start diving into more advance topics on how to hack Wi-Fi.
Long time reader, first time 'How To' poster. This tutorial has been highly requested. Here are the steps to perform a Pixie Dust attack to crack a WiFi password that has WPS enabled.
Welcome to the second Null Byte in a series educating you on Social Engineering awareness and techniques. Today, I'm going to show you how a saavy Social Engineer would trick a friend into unknowingly surrendering their Facebook password. My intent is to warn and demonstrate how easy it is to succumb to phishing via Social Engineering, and therefore expose yourself.
Hack Like a Pro: How to Find Vulnerable Targets Using Shodan—The World's Most Dangerous Search Engine
Welcome back, my greenhorn hackers! Sometimes, we don't have a specific target in mind, but rather we are simply looking for vulnerable and easy-to-hack targets anywhere on the planet. Wouldn't be great if we had a search engine like Google that could help us find these targets? Well, we do, and it's called Shodan!
We're nearly done getting our Mac set up for hacking. If you haven't checked out previous tutorials, I'd recommend you do so first before diving right into this one.
Welcome back, my budding hackers! Previous to this tutorial, we've focused mostly on hacking the target system. If we're successful in owning the target system, we'll then want to make certain that the system administrator doesn't know we were there, and that he or she cannot track us.
Welcome back, my novice hackers! The worst thing that can happen to any hacker is being detected by a security admin, the security technologies (IDS, firewall, etc.), or a forensic investigator.
Welcome back, my novice hackers! There are SOOOO many ways to hack a system or network, which means you need to think creatively in order to be successful.
Welcome back, my tenderfoot hackers! Recently, Microsoft released a new patch (September 8, 2015) to close another vulnerability in their Windows Vista, 7, 8, and 8.1 operating systems. The vulnerability in question (MS15-100) enabled an attacker to gain remote access to any of these systems using a well-crafted Media Center link (MCL) file.
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 to this short and easy tutorial on hacking and DDosing (is that even a word I don't know) anyways lets get started
Welcome Back !! TheGeeks. SQL Injection (SQLI) Part-1
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 ...
Hello, everyone! Many of you don‘t even know about my existence here on Null Byte, so I thought of contributing something rather interesting. Recently, someone asked how to make your own "Bad USB," and I promised to make a how-to on this topic. In addition, it would be nice to have something related on our WonderHowTo world. So here it is!
Welcome back, my apprentice hackers! In this series on password cracking, I have been attempting to develop your skills in the age-old art of password cracking. Although it might seem like a simple and straightforward exercise, those of you who have attempted password cracking know that there are many subtleties to this art.
This is my first contribution in an ongoing series on detailing the best free, open source hacking and penetration tools available. My goal is to show you some of the quality tools that IT security experts are using every day in their jobs as network security and pen-testing professionals. There are hundreds of tools out there, but I will focus and those that meet four key criteria:
Lockpicking is a skill that takes years upon years to master. Locks come in all sorts of shapes and sizes, but have common ground in how they work. Most cylinder locks have "tumblers," which are metallic cylindrical objects that sit vertically to the actual locking mechanism. Tumblers have five or six holes with rounded key pins of various height in them, each needing to meet an exact height or the cylinder in the center (the lock itself) will not be allowed to turn. This is the reason why yo...
Hey, hackers! Now that you've hacked/owned your first "box" in my last article, let's look a little closer at another great feature of Metasploit, the Meterpreter, and then let’s move on to hacking a Linux system and using the Meterpreter to control and own it.
Welcome back, my novice hackers! This new series on Bluetooth hacking was inspired by a recent episode of Mr. Robot (my favorite TV show). In episode 6, Eliot hacked the bluetooth keyboard of the police office in order to hack the prison and release his nemesis, Vera. This is just one of the many hacks we will explore in the series.
Welcome back, my fledgling hackers! A number of you have written me in recent weeks asking how to find IP addresses of a potential target. There are numerous ways to do this, but in this tutorial I will show you how to use a tool built into BackTrack that leverages Address Resolution Protocol or ARP to discover live hosts on the network.
Dirty, malformed, and outright mischievous text strings have long been the enemy of interactive website developers. Strings contain any combination of letters, numbers, spaces, and punctuation, and are entered into text boxes on websites by users. These strings in particular can do everything from highlighting XSS vulnerabilities to soliciting 404 error pages.
Welcome back, my budding hackers! One of the keys to becoming a professional and successful hacker is to think creatively. There is always a way to get into any network or system, if you think creatively. In previous tutorials, I have demonstrated ways to crack passwords on both Linux and Windows systems, but in this case, I will show you a way to get the sysadmin password by intercepting it from a Remote Desktop session.
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 a previous tutorial on hacking databases, I showed you how to find online databases and then how to enumerate the databases, tables, and columns. In this guide, we'll now exfiltrate, extract, remove—whatever term you prefer—the data from an online database.
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.
