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.

Hack Like a Pro: Advanced Nmap for Reconnaissance

Welcome back, my novice hackers! Reconnaissance is one of the most important preparatory steps to hacking. As I have emphasized many times before here on Null Byte, you must know the operating system, the ports, the services, the applications, and sometimes even the language of the target to be effective. If you haven't taken the time to gather this info, then you are likely wasting your time.

How To: Tactical Nmap for Beginner Network Reconnaissance

When it comes to attacking devices on a network, you can't hit what you can't see. Nmap gives you the ability to explore any devices connected to a network, finding information like the operating system a device is running and which applications are listening on open ports. This information lets a hacker design an attack that perfectly suits the target environment.

Dissecting Nmap: Part 1

Welcome aboard my inquisitive comrades. I am starting a new series that nobody expected coming. It may not seem very exciting at first, but await the last few parts as many startling discoveries will be made. This is a series which I plan to continue after the completion of Nmap, unless you have major objections.

Zanti: Nmap

In my last tutorial I very briefly introduced Zanti , but in this tutorial I will start to show its many features. The first step on hacking is recon . You could use Nmap , but the problem with Nmap on Android is that by itself, in order to gain full functionality your phone must be rooted. Thank goodness for a few geniuses in Zanti's dev team whom managed to implant full fuctionality of Nmap in Zanti without rooting your phone. With that being said, boot up your Android phone and lets start ...

How To: Automate Brute-Force Attacks for Nmap Scans

Using Hydra, Ncrack, and other brute-forcing tools to crack passwords for the first time can be frustrating and confusing. To ease into the process, let's discuss automating and optimizing brute-force attacks for potentially vulnerable services such as SMTP, SSH, IMAP, and FTP discovered by Nmap, a popular network scanning utility.

How To: Get Started Writing Your Own NSE Scripts for Nmap

The road to becoming a skilled white hat is paved with many milestones, one of those being learning how to perform a simple Nmap scan. A little further down that road lies more advanced scanning, along with utilizing a powerful feature of Nmap called the Nmap Scripting Engine. Even further down the road is learning how to modify and write scripts for NSE, which is what we'll be doing today.

How To: Do an Idle Scan with Nmap

Welcome back my fellow hackers. Today I'm going to teach you how to preform an Idle Scan. You may be asking what is an Idle Scan. Its a very stealthy scan because you don't use your own ip you use a zombie (in computer terms).

How To: Enumerate NetBIOS Shares with NBTScan & Nmap Scripting Engine

NetBIOS is a service that allows for communication over a network and is often used to join a domain and legacy applications. It is an older technology but still used in some environments today. Since it is an unsecured protocol, it can often be a good starting point when attacking a network. Scanning for NetBIOS shares with NBTScan and the Nmap Scripting Engine is a good way to begin.

How to do an NMAP scan on Armitage to find IPs within a certain range. Armitage is a gui interface of Metasploit, and advanced hacking/exploiting program. It can be downloaded from http://metasploit.com/ and http://fastandeasyhacking.com/ and you will need NMAP. http://www.nmap.org/

How To: Port scan with Nmap

Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they a...

How To: Use the Nmap security tool

This hour-long hacking tutorial looks at the Nmap security scanner. In particular, this Nmap tutorial looks at port scanning concepts, TCP three way handshake, stealth scans, idle scans, bounce scans, version detection, OS detection, NSE/LUA scripting and firewall logs. To get started using Nmap, watch this video tutorial. Use the Nmap security tool.

Hacking Reconnaissance: Finding Vulnerabilities in Your Target Using Nmap

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 root boxes, you'll need to learn how to perform the necessary reconnaissance first. In fact, you will spend far more time researching your target then you will exploiting it. In this article, I am going to show you the fi...

How to Hack Databases: Hunting for Microsoft's SQL Server

Welcome back, my fledgling hackers! The database is the hacker's "pot-of-gold," as it contains information that is very valuable to both the business and the hacker. In this, the second of my series on hacking databases, we're on the "hunt" for Microsoft's SQL Server. Although far from the most commonly used database (Oracle hold's that title), Microsoft's SQL Server is very often found in small-to-medium sized businesses. Even a few big businesses use it.

Hack Like a Pro: Scripting for the Aspiring Hacker, Part 2 (Conditional Statements)

Welcome back, my greenhorn hackers! I recently began a series on scripting and have received such positive feedback that I'm going to keep this series going. As I've said before, to graduate from the script kiddie to the pro hacker, you'll need to have some scripting skills. The better you are at scripting, the more advanced your hacking. Ultimately, we are leading up to developing the skills to build your own zero day exploits.

Hack Like a Pro: How to Perform Stealthy Reconnaissance on a Protected Network

Welcome back, my fledgling hackers! One of the first issues any hacker has to address is reconnaissance. Before we even begin to hack, we need to know quite a bit about the target systems. We should know their IP address, what ports are open, what services are running, and what operating system the target is using. Only after gathering this information can we begin to plan our attack. Most hackers spend far more time doing reconnaissance than exploiting.

How To: Use Magic Tree to Organize Your Projects

MagicTree is often the go-to tool for data collection and reporting for many pentesters. It organizes data in nodes in a tree-structure which is very efficient at managing host and network data. Reports can be completely customized to meet the user's needs. Also, MagicTree allows you to import XML data and has XSLT transforms for Nessus, Nmap, OpenVas, Burp, Nikto. MagicTree comes pre-installed in Kali.

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.

How To: Gain SSH Access to Servers by Brute-Forcing Credentials

SSH is one of the most common protocols in use in modern IT infrastructures, and because of this, it can be a valuable attack vector for hackers. One of the most reliable ways to gain SSH access to servers is by brute-forcing credentials. There are a few methods of performing an SSH brute-force attack that will ultimately lead to the discovery of valid login credentials.
