Welcome back, my budding hackers! In previous tutorials, we've looked at some of the basic commands and concepts for using Linux. Along the way, I realized that I've failed to provide you with some basic background material on the stdin, stdout, and stderror.
Do you have an Alfa AWUS036NH Wi-Fi adapter that claims it can go to 2000 mWs, or some card that can supposedly transmit power over 1000 mW? If so, you may have run into problems setting your card's TXPOWER higher than 30 dBm, which is about 1000 mW. Well, I will show you how to break that barrier and go as high as you want!

Dr. Preis has received Top Doctors recognition in the last 10 years of Castle Connelly's Directory. This video is perfect for parents and gives advice on recognizing if lack of eye contact may be a sign of Autism.
Oded Preis MD FAAP Associate Clinical Professor of Pediatrics SUNY Downstate Brooklyn Dr. Preis has received Top Doctors recognition in the last 10 years of Castle Connelly's Directory. In this DrMDK video, he discusses what bonding is and how to bond in birthing centers.
This tutorial teaches how to create new folders and files and how to move them to new directories using cPanel.
The free download manager wget lets you download all the files on a page or directory with a single command. It also allows you to resume downloads after getting disconnected letting you start where you left off instead of starting the download at 0% again. Check out this tutorial and see how to install and use wget.
Samba can be configured to allow any user with write access the ability to create a link to the root filesystem. Once an attacker has this level of access, it's only a matter of time before the system gets owned. Although this configuration isn't that common in the wild, it does happen, and Metasploit has a module to easily exploit this security flaw.
Passwords stored in web browsers like Google Chrome and Mozilla Firefox are a gold mine for hackers. An attacker with backdoor access to a compromised computer can easily dump and decrypt data stored in web browsers. So, you'll want to think twice before hitting "Save" next time you enter a new password.
After a hacker has configured Metasploit on a remote private server, created a resource script for automation, and created a simple payload, he or she can begin the process of remotely controlling someone's Windows 10 computer with just a few moments of physical access — even if the computer is off.
Configuring onion services for the first time can be tricky. A surprising number of system administrators make seemingly trivial mistakes that ultimately lead to catastrophic cases of de-anonymizing supposedly anonymous sites on the dark web. OnionScan is a tool designed to identify common misconfigurations in onion services and aid us in understanding how to fix them.
The default tool for payload generation is MSFvenom, a Metasploit standalone payload generator as well as encoder. This tool is an incredibly powerful tool for payload generation, but it can be difficult and requires a bit of reading for newer users.
Welcome back, my greenhorn hackers! A few years back, Microsoft implicitly recognized the superiority of the Linux terminal over the GUI-based operating system by developing PowerShell. Since Windows 7, every Windows operating system has had PowerShell installed by default, and they even made PowerShell capable of running Linux commands on Windows!
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.
This tutorial was written with Windows 7 in mind, but the principle applies to all versions starting from 7.
How's it goin'? In this tutorial, we will learn about the security issues of the popen and system functions. I've seen a few people attempting to run command line utilities or whatever it is they require with calls to these two functions but may not know the security implications which come along with it. I will show you using an example from the wargame IO Smash The Stack.
Hello friends. This is actually my first how to.
Welcome back, my aspiring hackers!
Welcome back, my newbie hackers! Recently, I "upgraded" to Kali as my hacking platform, despite my preference for BackTrack. I did this reluctantly, primarily because new readers here could no longer download BackTrack from their site. I want to point out here that we all must keep in mind that with any software—or for that matter, any product—that is newer is not necessarily better.
Welcome back, my aspiring hackers! One of those areas of Linux that Windows users invariably struggle with is the concept of "mounting" devices and drives. In the Windows world, drives and devices are automatically "mounted" without any user effort or knowledge. Well, maybe a bit of knowledge. Most Windows users know to unmount their flash drive before removing it, but they usually think of it as "ejecting" it.
Welcome back, my hacker apprentices! In recent weeks, the revelation that the NSA has been spying on all of us has many people up in arms. I guess I take it all in stride as I just assume that the NSA is spying on all of us—all of the time. Don't get me wrong, I don't condone it, but I know the NSA.
Gigafide explains that with so many different social networking sites, it is hard to keep information up to date on all of them. He first introduces TweetDeck, an amazing desktop application that allows a user to update information for their Twitter, Facebook, MySpace, and LinkedIn accounts. If you don't want to go through the hassle of installing TweetDeck on your computer, there is HootSuite, a web application that allows you to do this and if you're interested in keeping track of much more...

We look at how to find the existing and new starter kits for VB 2005. We run the RSS Screen Saver starter kit. Next, we will modify the kit and install the screen saver.
Analysis of photographs and social connections can be a huge component of social engineering. Understanding who a person is, as well as who they know, can establish links within a company. This information could be used by hackers to execute elaborate social engineering attacks.
Hello Everyone! I wanted to share a free and open source note taking tool that I've been using for quite some time now.
In the wake of its 20th anniversary, the folks over at Eltechs have released Original DOOM, a full shareware version of the revolutionary first-person shooter DOOM for Android, available for free on the Google Play Store. It's unmodded and unaltered from the original FPS classic.

The art of privilege escalation is a skill that any competent hacker should possess. It's an entire field unto itself, and while it's good to know how to perform the techniques involved manually, it's often more efficient to have a script automate the process. LinEnum is one such script that can be incredibly useful for privilege escalation on Linux systems.
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 restricted files that contain info about all registered users on the system, their permissions, and encrypted passwords.
It's important to know who you're dealing with after hacking your target's MacBook. Getting remote access is simple, but covertly gathering information about the user and their system can be a challenge.
Transferring hundreds of screenshots, webcam recordings, keystroke logs, and audio recordings between your VPS and a local Kali machine can be tricky. Services like Dropbox don't always have the best privacy policies and suffer data breaches just like any other website. To mitigate these risks, we'll use a secure, open source, and decentralized alternative.
Hello, everyone! If you haven't read the recent announcement on the official release of the Null Byte suite, I suggest you do so. This is going to be a quick tutorial on how to download and install the suite so you can see our communities genius. So, let's get started!
Welcome back, my hacker novitiates! In an earlier Linux Basics tutorial, I had demonstrated the basics of the Apache web server. Since Apache is the world's most widely used web server on the Internet (as of July 2015, Apache was 38%, IIS was 26%, and Nginx is 15%), the more you know about it and understand it, the more success you are likely to have hacking it.
Welcome back, my tenderfoot hackers! One of the issues we often encounter with Metasploit is how to add new modules. Although Rapid7 (Metasploit's owner and developer) periodically updates Metasploit with new exploits, payloads, and other modules, at times, new modules appear that are not added to the Metasploit repository.
