How To: Get Root Filesystem Access via Samba Symlink Traversal

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.

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: Exploit Remote File Inclusion to Get a Shell

A simple security flaw can allow an attacker to gain a strong foothold with little effort on their part. When a web application permits remotely hosted files to be loaded without any validation, a whole can of worms is opened up, with consequences ranging from simple website defacement to full-on code execution. For this reason, RFI can be a promising path to obtaining a shell.

How To: Exploit Shellshock on a Web Server Using Metasploit

One of the most critical bugs to come out in the last five years was Shellshock, a vulnerability which allows attackers to execute arbitrary code via the Unix Bash shell remotely. This vulnerability has been around for a while now, but due to the ubiquity of Unix machines connected to the web, Shellshock is still a very real threat, especially for unpatched systems.

How To: Use Beginner Python to Build a Brute-Force Tool for SHA-1 Hashes

Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal. Due to the way hashes work, not all are created equal. Some are more vulnerable than others, and a little Python could be used to brute-force any weak hashes to get the passwords they were created from.

IFTTT 101: Secure Your Automations with 2-Step Verification

If you want to automate tasks with your smartphone, IFTTT is a great app. It does a tremendous job of helping you find applets or creating your own from scratch, so it's easy to connect your favorite online services and make them react to each other. With all this personal information, though, you should ensure that your data is secure by enabling two-step verification.

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.

How To: Create a Reusable Burner OS with Docker, Part 1: Making an Ubuntu Hacking Container

Containers are isolated software instances representing applications, servers, and even operating systems—complete with all of their dependencies, libraries configuration files, etc.—and they're taking over the corporate world. The ephemeral, portable nature of containers help them stay current and speedy, and they can work on pretty much any computer, virtual machine, and cloud.

News: How to Write Better Code

Programming is an essential thing in hacking/pentesting, and at times, I do not feel that it is being addressed enough here, at Null-byte. I understand that this is a forum dedicated for hacking, but I'll address some of the stuff I feel is muy importante about programming. I am not a professional programmer, but I do have experience and I do want to share some of the stuff professionals have taught me.
