Remember that scene in The Matrix when Trinity uses a realistic Nmap port scan, followed by an actual SSH exploit (long since patched) to break into a power company? Well, believe it or not, but that scene is not far fetched at all. If you want to exploit vulnerabilities and r ...more
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 ...more
Welcome back, my greenhorn hackers. When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications confidentiality. WEP, as it became known, proved terribly flawed and easily cracked. You can read more about that in my b ...more
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. Please note, this attack is very specific in nature. I've had a lot of success running this ...more
Welcome back, my rookie hackers! Many newbie hackers focus upon the technical aspects of hacking and fail to give enough attention to social engineering. In fact, I would say that technical hacks should ONLY be attempted if social engineering attacks fail. Why bother spending ...more
Welcome back, my novice hackers! In a recent tutorial, I showed how the SNMP protocol can be a gold mine of information for reconnaissance on a potential target. If you haven't already, I strongly suggest that you read it before progressing here, as little of this will make m ...more
Welcome back, my greenhorn hackers! Earlier in this series, I showed a you a couple of different ways of fingerprinting webservers. Probably the easiest way, is to use netcat and connect to port 80 and pull the webserver banner. The banner is simply the application advertisi ...more
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 hacke ...more
Welcome back, my budding hackers! When we are looking for ways to hack a system, we need a specific exploit to take advantage of a certain vulnerability in the operating system, service, or application. Although I have shown you multiple ways to exploit systems here in Null B ...more
Welcome back, my fledgling hackers! Nearly every commercial enterprise worth hacking has an intrusion detection system (IDS). These network intrusion detection systems are designed to detect any malicious activity on the network. That means you! As the name implies, a networ ...more
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. Every time we send a packet to our intended target, that packet contains our IP ...more
Welcome back, my greenhorn hackers! Lately, much of the discussion here on Null Byte has revolved around evading detection and not getting caught hacking. Several of you have written me asking for a series on evading detection and forensics, and while I began a series 5 month ...more
Today, I want to share a tutorial on one of the most useful but old methods which you could use to hack websites, that is using the Dot net nuke (DNN) vulnerability . I know some of you already know about this method. Note: This method only works if the website has the vulner ...more

Android has several features built into the platform that improve user experience but require extra attention to prevent a security breach. By modifying these settings, you can drastically reduce the possibility of someone exploiting your device or intercepting information. B ...more
Welcome back, my greenhorn hackers! Recently, I asked the Null Byte community what subject they would most like me to cover in future tutorials. Many of you cited scripting, and I decided it's best to cover this subject soon, so here goes. Any self-respecting hacker must be ...more
Welcome back, my neophyte hackers! I have already done a few tutorials on password cracking, including ones for Linux and Windows, WEP and WPA2, and even online passwords using THC Hydra. Now, I thought it might be worthwhile to begin a series on password cracking in general. ...more
With all the web applications out on the internet today, and especially the ones built and configured by novices, it's easy to find vulnerabilities. Some are more perilous than others, but the consequences of even the slightest breach can be tremendous in the hands of a skille ...more
Directory traversal, or path traversal, is an HTTP attack which allows attackers to access restricted directories by using the ../ characters to backtrack into files or directories outside the root folder. If a web app is vulnerable to this, an attacker can potentially access ...more
Welcome back, my hacker apprentices! My recent posts here in Null Byte have been very technical in nature, so I thought that I'd have a little fun with this one. Have you ever had an annoying neighbor whose dog barks all night, who has loud parties that keep you awake, or who ...more
Welcome back, my hacker apprentices! I recently began a new series on digital forensics to show aspiring hackers what the forensic investigator can do and see while investigating a cyber attack. This is the second installment in that series and will focus upon network forensi ...more
Maybe you thought sitting behind a Mac gives you special protection when it comes to getting hacked. Thanks to a a new report from Check Point, you can kiss that theory goodbye. The cyber security company just uncovered the latest strain of malware — OSX/Dok — infecting all ve ...more
Welcome back, my hacker novitiates! A short while ago, I introduced you to regular expressions. Regular expressions are a language that is particularly useful for finding complex text patterns in streams of data. Although first developed for Perl, regular expressions are use ...more
Welcome back, my fledgling hackers! A short while ago, I did a tutorial on conducting passive OS fingerprinting with p0f. As you remember, p0f is different from other operating system fingerprinting tools as it does not send any packets to the target, instead it simply takes ...more
