If you've been around computers long enough, you've probably heard the phrase "have you tried turning it off and on again?" This trick usually works because it forces your computer to empty out the contents of its RAM and disk caches when you restart.
Welcome back, my greenhorn hackers! Over the years, I have written many articles here on Null Byte chronicling the many the hacks of the NSA, including the recent hack of the Juniper Networks VPN. (By the way, my speculation in that article has proven to be correct. The NSA did embed a backdoor on those devices.)
We all know them, and many of us despize them. And some might support them, regardless many have different opinions.
Welcome back everyone. As many of you know, reconnaissance is extremely important in any successful hack. Without proper reconnaissance, we won't know what we're about to get into, literally.
Managing hard drives in Linux is crucial to understanding your system and its operation as well as understanding the system you are exploiting or conducting a forensic analysis on. Linux has numerous commands that can provide us with information, control, and management of hard drives, and in this tutorial, we will examine a number of the most important ones.
Continuing this series, I am now moving on to the section, 'Anonymous'. Hope you are looking forward to read this.
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.
If your Android device wasn't manufactured by Samsung, chances are it uses on-screen navigation buttons. Colloquially referred to as "Soft keys," these have become commonplace due to their flexibility, as well as the fact that manufacturers don't have to include extra hardware buttons with a propensity to fail.
In recent weeks, major bank websites around the world have experienced outages after being have been hit with Distributed Denial of Service (DDoS) attacks. Although few, if any, of these banks have been totally knocked offline, these DoS attacks have dramatically slowed the response time of their websites to legitimate customers. The most recent victim was the Royal Bank of Scotland. Due to this attack, RBS customers were unable to access their accounts for about an hour last week.
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.
Notes on iOS has never been a particularly great app due to a lack of overall features compared to other note-taking apps like Evernote or Microsoft OneNote.
KNOX is a major pain for Samsung owners who like to modify their devices. Its combination of hardware and software security measures make things rather difficult when you're trying to modify system-level files and functions without voiding your warranty.
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.
In the realm of Android mods, none is more powerful than a custom recovery. This is installed in place of the stock offering, and it lets you back up your entire system, flash mods, and install custom ROMs.
Modern medicine utilizes cutting-edge technology more than ever, so it would only make sense that the powerful handheld computers we all carry around these days could play a big role in wellness.
If you're anything like me, you probably think it's borderline sacrilege to even think about a sandwich or a burger that doesn't have a layer of smooth mayonnaise. But I don't just keep a jar of it in my fridge for lunch—it's also there for practical purposes.
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.
The Nexus Player is one of the most robust set-top streaming devices on the market. This is mainly due to the fact that the base software it runs is a direct fork of Android, which is a very powerful operating system itself.
Willpower is a pretty significant word. It's the difference between sticking with a clean eating diet and diving face-first into a plate of brownies. It's what drags you out of bed on Monday mornings and into work rather than letting you stay snuggled under the covers asleep. And, most importantly, it's the kick in the butt we all require to both accomplish goals and make changes.
Unlike wine, you can't re-cork or stopper leftover bubbly after you've opened it, but all is not lost even if you haven't managed to finish every last drop. You can use your leftover champagne to make light-as-air crêpes or pancakes, to create a detox face mask, to cook seafood and rice, or to make dips and salad dressings.
There are certain foods and beverages that can actually brighten your smile or improve your dental health when you chew or sip them. Once you understand their chemical properties or textures, you can look to items you already have in your cupboards or refrigerator to help keep your teeth looking and feeling their best.
Injustice: Gods Among Us is one of the most popular games to come out over the last couple of years. It was a hit on video game consoles, and it's got a solid 4.5 rating on both Google Play and the iOS App Store, with almost 2 million people rating the game combined.
The first few times I posted on some of the Android forums out there, I asked things like "Does anybody how I can make my phone do this or that?" Without fail, the responses to these types of questions were always one word—Tasker.
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 novice hackers! In my series on cracking passwords, I began by showing off some basic password-cracking principles; developed an efficient password-cracking strategy; demonstrated how to use Hashcat, one of the most powerful password-cracking programs; and showed how to create a custom wordlist using Crunch. In this tutorial, I will show you how to create a custom wordlist based upon the industry or business of the targets using CeWL.
Welcome back, my fledgling hackers! Sometimes, for a variety of reasons, we can only get a command shell on our target system. For instance, with Metasploit, it's not always possible to get the all powerful Meterpreter on our target system. In other cases, we may be able to connect to a command shell via Netcat or Cryptcat.
Welcome back, my nascent hackers! We have spent a lot of time in previous tutorials focused on hacking the ubiquitous Windows systems, but the vast majority of "heavy iron" around the world are Linux or Unix systems. Linux and Unix dominate the world of Internet web servers with over 60% of the market. In addition, Linux and Unix servers are the operating system of choice for major international corporations (including almost all the major banks) throughout the world.
It didn't take long at all for developer Chainfire to sort out a root method for the new Android 5.0 Lollipop. After handling a few issues with changes to the SELinux kernel module, Chainfire pushed out an update to his popular SuperSU root app.
Loaded with a gorgeous display and a powerful processor, the Kindle Fire HDX is an impressive all-around tablet, especially when it's used for what Amazon Kindles were built for—reading electronic versions of novels, textbooks, and other printed works.
With Safestrap bringing custom recovery functionality to the AT&T and Verizon Wireless variants of the Samsung Galaxy S5, it's high time we covered this process for all other versions of the GS5.
When people first learn that their Android device is capable of dual-booting different operating systems, e.g. Linux, they almost universally respond with, "That's so cool." And for those of us ambitious enough to actually try one out, we are typically filled with glee as we see Ubuntu, or something similar, boot up for the first time on our tablet or phone.
Resflux is an Xposed mod developed by Julian Paolo Dayag, aka WisdomSky, that provides users with a straightforward and functional way to customize and theme almost every aspect of the packages (apps and system components) installed on their Android device.
This year's I/O was all about bringing Android into the future and onto new devices. On top of announcing the upcoming "L" release of its mobile OS, Google showcased Android Wear, Android Auto, and Android TV.
Have you ever fallen victim to a clever Jedi mind trick? Don't worry. It happens. There are evolutionary reasons as to why our brains sometimes give into the oldest tricks in the book. Fortunately, the more you understand the tricks of a salesman, the easier it is to avoid their gripping psychological influence. Clue #1: Too Much Specificity
If you've ever used the automation app Tasker, then you know exactly how powerful the tool can be. If you haven't, suffice it to say that there's virtually nothing on your Android phone that Tasker can't automatically do for you.
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!
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 novice hackers! We've done a number of tutorials using one of my favorite hacking tools, Metasploit. In each of them, we've used the msfconsole, which can be reached through either the menu system or through simply typing "msfconsole" from the terminal.
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 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.
