How To: Scan for Viruses in Windows Using a Linux Live CD/USB

Many windows users, if not all, run into a virus infection once in a while. This is unavoidable when using Microsoft's operating system. Without digressing too much, the fact that Windows is such a popular OS with no controlled software sources makes it easy for viruses and malware to spread. And while there's a plethora of antivirus tools for Windows, sometimes infections (such as certain scareware) can disable the install and/or use of antivirus systems and render your OS unusable until cle...

How To: Spy on SSH Sessions with SSHPry2.0

SSH, or the secure shell, is a way of controlling a computer remotely from a command-line interface. While the information exchanged in the SSH session is encrypted, it's easy to spy on an SSH session if you have access to the computer that's being logged in to. Using a tool called SSHPry, we can spy on and inject commands into the SSH sessions of any other user logged in to on the same machine.

How To: Use Private Encrypted Messaging Over Tor

Tor is an excellent obfuscation network for web traffic, and while instant messaging over the network is very useful, it can be relatively difficult to configure. In this guide, we'll look at two synchronous communications platforms (instant messengers) which can be routed over the Tor network, Ricochet and XMPP.

How To: Identify Missing Windows Patches for Easier Exploitation

No operating system is stricken with as many vulnerabilities as Windows, and it's often a race to release the latest patches to fix things. From an attacker's point of view, knowing which patches are present on a Windows machine can make or break successful exploitation. Today, we will be covering three methods of patch enumeration, using Metasploit, WMIC, and Windows Exploit Suggester.

How to Hack Databases: Cracking SQL Server Passwords & Owning the Server

Welcome back, my rookie hackers! A short while back, I began a new series on database hacking, and now it's time to continue and extend your education in that field. As you know, the database contains all of the most valuable info for the hacker, including personally identifiable information, credit card numbers, intellectual property, etc. So, it's the ultimate goal of cybercrime and the APT hacker.

How To: Upgrade a Normal Command Shell to a Metasploit Meterpreter

When attempting to compromise a target, we want as much control as possible over the victim. Metasploit's meterpreter allows us to have immense control over the victim, the only issue is that sometimes we can't land a meterpreter. We may only be able to land a standard shell, but fear not, there is a way to upgrade our shell into the all powerful meterpreter!

How To: Install an Off-the-Shelf Hard Drive in an Xbox 360 (Get 10x the GB for Your Money)

Since the day of the Xbox 360 release, storage space for the device has been overpriced beyond belief. OEM 250GB HDD models still cost $110 USD! A 250GB hard drive should not destroy my wallet, Microsoft. Storage space, especially on HDDs, is cheap. You can buy a removable 2TB external for only $100 USD, so it's a little beyond my comprehension to see how they calculate their MSRP to yield such a large profit. On the other hand, Xbox 360 had very impressive hardware specs back in the day, equ...

Hack Like a Pro: Metasploit for the Aspiring Hacker, Part 12 (Web Delivery for Linux or Mac)

Welcome back, my budding hackers! Metasploit, one of my favorite hacking/pentesting tools, has so many capabilities that even after my many tutorials on it, I have only scratched the surface of it capabilities. For instance, it can be used with Nexpose for vulnerability scanning, with Nmap for port scanning, and with its numerous auxiliary modules, nearly unlimited other hacking related capabilities.

Hack Like a Pro: Digital Forensics for the Aspiring Hacker, Part 3 (Recovering Deleted Files)

Welcome back, my tenderfoot hackers! I recently began a new series on digital forensics to help tenderfoot hackers from being detected and ultimately, incarcerated. In this installment of that series, we will look at recovering deleted files. This is important to hackers because you need to know that even when you delete files on your computer or on the victim's computer, a forensic investigator can usually recover them.

How To: Use the USB Rubber Ducky to Disable Antivirus Software & Install Ransomware

Ransomware is software that encrypts a victim's entire hard drive, blocking access to their files unless they pay a ransom to the attacker to get the decryption key. In this tutorial, you'll learn how easy it is to use the USB Rubber Ducky, which is disguised as an ordinary flash drive, to deploy ransomware on a victim's computer within seconds. With an attack that only takes a moment, you'll need to know how to defend yourself.

How To: Install Gitrob on Kali Linux to Mine GitHub for Credentials

GitHub is an extremely popular site that allows developers to store source code and interact with other users about their projects. Anyone can download public, open-source files on GitHub manually or with Git, and anyone can fork off someone's project to expand or improve it into its own project. It's a really great site for programmers, developers, and even inspiring hackers.

SQL Injection 101: Advanced Techniques for Maximum Exploitation

For SQL injection, the next step after performing reconnaissance and gathering information about a database is launching an attack. But something seems off .. in the real world, it's usually not quite as simple as passing in a few fragments of SQL code to an input field and seeing all that glorious data displayed right in the browser. This is when more advanced techniques are needed.

Exploit Development: How to Read & Write to a Program's Memory Using a Format String Vulnerability

Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.

News: Change from BASH to zsh

Hello fellow Null-Byters today I will be showing you how to change from the simple but powerful BASH system to a more powerful and faster Z - Shell system. This change can be permanent if you want but doesn't have to be, and it is an extremely simple one to perform.
