How To: Linux Basics for the Aspiring Hacker: Using Start-Up Scripts
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.

Hack Like a Pro: How to Fingerprint Web Servers Using Httprint
Welcome back, my greenhorn hackers! Earlier in this series, I showed a you a couple of different ways of fingerprinting webservers. Probably the easiest way, is to use netcat and connect to port 80 and pull the webserver banner.

How To: Extract Windows Usernames, Passwords, Wi-Fi Keys & Other User Credentials with LaZagne
After exploiting a vulnerable target, scooping up a victim's credentials is a high priority for hackers, since most people reuse passwords. Those credentials can get hackers deeper into a network or other accounts, but digging through the system by hand to find them is difficult. A missed stored password could mean missing a big opportunity. But the process can largely be automated with LaZagne.

Hacking Windows 10: How to Remotely Record & Listen to the Microphone of a Hacked Computer
The microphone in a Windows computer is accessible to most applications running on the device at all times and completely without security limitations. Information gathered from recorded audio conversations taking place in the surrounding area of a compromised computer can be used for social engineering, blackmail, or any number of other reasons.

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.

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.

Surveillance is always a useful tool in a hacker's arsenal, whether deployed offensively or defensively. Watching targets yourself isn't always practical, and traditional surveillance camera systems can be costly, lacking in capabilities, or both. Today, we will use motionEyeOS running on a Raspberry Pi Zero to create a small, concealable Wi-Fi connected spy camera that is both affordable and easily concealed.

Hello fellow gray hat hackers, I wrote a program in python that helps me to fill up my proxychains.conf file, so I don't have to manually enter in the proxies. I figured I will give a little how-to of how I did it and maybe I could help some of you(hackers) out there to stay anonymous.

Post-exploitation is often not quite as exciting as popping the initial shell, but it's a crucial phase for gathering data and further privilege escalation.

SSL stands for Secure Socket Layer. It's an encryption standard used on most sites' login pages to avoid their users' passwords being packet sniffed in simple plain-text format. This keeps the users safe by having all of that traffic encrypted over an "https" connection. So, whenever you see "https://" in front of the URL in your browser, you know you're safe... or are you?
