How To: Easily Detect CVEs with Nmap Scripts

Nmap is possibly the most widely used security scanner of its kind, in part because of its appearances in films such as The Matrix Reloaded and Live Free or Die Hard. Still, most of Nmap's best features are under-appreciated by hackers and pentesters, one of which will improve one's abilities to quickly identify exploits and vulnerabilities when scanning servers.

Exploit Development: How to Manipulate Code Execution with the Instruction Pointer

The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.

How To: Use a Misconfigured SUID Bit to Escalate Privileges & Get Root

Gaining access to a system is always exciting, but where do you go from there? Root or bust. Sure, a compromised host is a great way to run a botnet, or do some other boring, nefarious thing—but as hackers, we want root. We also want to take the easiest path possible, search out low-hanging fruit, and exploit them. SUID programs are the lowest of the low-hanging fruit.

SEToolkit: Metasploit's Best Friend

If you read my last tutorial on using SEToolkit, you probably know that SEToolkit is an effective way to make malicious actions look legitimate. But, that was only the beginning... the truth is, Metasploit and SEToolkit belong together, and help each other very well.

News: Why Is Linux & Other Open-Source Software Free?

Welcome back, my greenhorn hackers! As hackers, we often take for granted that nearly all of our hacking tools and operating system are free and open source. I think it's important to examine a bit of background on how we arrived at this intriguing juncture in the history of computer software. After all, we pay for nearly all of our other software (Microsoft, Adobe, etc.) and nearly everything else we use in life, so how is it that Linux and all our hacking tools are free?

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: Fix Bidirectional Copy/Paste Issues for Kali Linux Running in VirtualBox

Last week, I updated VirtualBox on my computer since I had skipped a few versions, then I could no longer copy text or paste text from my Kali virtual machine to my host OS and vice versa. Installing the Guest Additions didn't seem to do anything, and the bidirectional shared clipboard was enabled, but there was one thing that did work for me that may help you out too if you experience the issue.

How To: Target Bluetooth Devices with Bettercap

An incredible amount of devices use Bluetooth or Bluetooth Low Energy to communicate. These devices rarely have their radios switched off, and in some cases, are deliberately used as trackers for lost items. While Bluetooth devices support MAC address randomization, many manufacturers do not use it, allowing us to use tools like Bettercap to scan for and track Bluetooth devices.

How To: Use Command Injection to Pop a Reverse Shell on a Web Server

Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.

How To: Use the Cowrie SSH Honeypot to Catch Attackers on Your Network

The internet is constantly under siege by bots searching for vulnerabilities to attack and exploit. While conventional wisdom is to prevent these attacks, there are ways to deliberately lure hackers into a trap in order to spy on them, study their behavior, and capture samples of malware. In this tutorial, we'll be creating a Cowrie honeypot, an alluring target to attract and trap hackers.

How To: Detect BlueBorne Vulnerable Devices & What It Means

Armis Labs has revealed eight vulnerabilities, called "BlueBorne", which put 5.3 billion Android, iOS, Windows, and Linux devices that use Bluetooth at risk. With it, hackers can control devices, access data, and spread malware to other vulnerable devices through networks. In this post, we will learn about the vulnerabilities, then look at how to find devices that have them.

News: New Siri Bug Lets Anyone Bypass Your Lock Screen to See Photos & Contacts

A new iPhone exploit has recently been discovered by YouTube user videosdebarraquito, who has found many other exploits and bugs in iOS over the years. This new exploit allows someone to bypass the lock screen and gain access to contacts and photos via Siri, Apple's digital voice assistant—but it only affects the iPhone 6s and the iPhone 6s Plus because it requires 3D Touch functionality.

How To: Use Meterpeter on OS X

Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on OS X (it has several more commands/options), but I think it is still worth noting how to do it. I've even seen some people mistakenly say that Meterpreter can only be run on Windows, which is not true. Meterpreter can ea...
