Hack Like a Pro: How to Use PowerSploit, Part 1 (Evading Antivirus Software)
Welcome back, my greenhorn hackers! A few years back, Microsoft implicitly recognized the superiority of the Linux terminal over the GUI-based operating system by developing PowerShell. Since Windows 7, every Windows operating system has had PowerShell installed by default, and they even made PowerShell capable of running Linux commands on Windows!
How To: Android CyanogenMod Kernel Building: Monitor Mode on Any Android Device with a Wireless Adapter
Hi, everyone! Recently, I've been working on a pretty interesting and foolish project I had in mind, and here I'm bringing to all of you my findings. This guide's main aim is to document the process of building an Android kernel, specifically a CyanogenMod kernel and ROM, and modifying the kernel configuration to add special features, in this case, wireless adapter Alfa AWUS036H support, one of the most famous among Null Byters.
SQL Injection 101: How to Avoid Detection & Bypass Defenses
It is often said that the best hackers remain unknown, and the greatest attacks are left undiscovered, but it's hard for an up-and-coming penetration tester or white hat to learn anything unless one of those factors is actually known or discovered. But the end goal here in our SQL injection lessons is to make that statement as true as possible for us when performing our hacks.
Hack Like a Pro: Denial-of-Service (DoS) Tools & Techniques
Welcome back, my fledgling hackers! Over the years, we have examined multiple ways to own, exploit, or compromise a system. On the other hand, we have not spent a lot of time on denial-of-service (DoS) attacks.
How To: Use Google Search Operators to Find Elusive Information
Google is an incredibly useful database of indexed websites, but querying Google doesn't search for what you type literally. The algorithms behind Google's searches can lead to a lot of irrelevant results. Still, with the right operators, we can be more exact while searching for information that's time-sensitive or difficult to find.
Raspberry Pi: Metasploit
Before we dive into the world of frustration, I first would like to thank whoever of the admins and mods made the folder for Raspberry Pi in the How-To's, thank you. Now with that outta the way, this article is about Metasploit on Raspberry Pi (hence the title). I should say that I ran into a error, but I think I figured what the problem is. First of all this is not on Kali Linux, but on a regular Linux OS. With that said let's open up a terminal and begin.
How To: The Ultimate Guide to Hacking macOS
Apple's macOS operating system is just as vulnerable to attacks as any Windows 10 computer or Android smartphone.

In this always-updated guide, we'll outline dozens of macOS-specific attacks penetration testers should know about.
Hacking macOS: How to Perform Situational Awareness Attacks, Part 1 (Using System Profiler & ARP)
The first few minutes after gaining access to a MacBook are critical — but where do we begin? Using tools built into macOS, we can develop an in-depth understanding of running background processes, detect antivirus software, locate sensitive files, and fingerprint other devices on the network. All of this can be done without installing additional software or modifying any files.
How To: Find & Exploit SUID Binaries with SUID3NUM
File permissions can get tricky on Linux and can be a valuable avenue of attack during privilege escalation if things aren't configured correctly. SUID binaries can often be an easy path to root, but sifting through all of the defaults can be a massive waste of time. Luckily, there's a simple script that can sort things out for us.
How To: Steal macOS Files with the USB Rubber Ducky
If you need a tiny, flexible attack platform for raining down human-interface-device (HID) attacks on unattended computers, the USB Rubber Ducky is the most popular tool for the job. By loading the Ducky with custom firmware, you can design new attacks to be effective against even air-gapped computers without internet access.

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: Hack SAML Single Sign-on with Burp Suite
Single sign-on (SSO) lets users login across different sites without having to manage multiple accounts. I'm sure most of us appreciate the convenience of seeing "Sign in with …" buttons that let us login with a single username. Hackers, however, see a possible avenue for exploitation, and you'll soon learn how an attacker can exploit a SAML vulnerability to assume another user's identity.
How to Hack Wi-Fi: Hunting Down & Cracking WEP Networks
While the security behind WEP networks was broken in 2005, modern tools have made cracking them incredibly simple. In densely populated areas, WEP networks can be found in surprising and important places to this day, and they can be cracked in a matter of minutes. We'll show you how a hacker would do so and explain why they should be careful to avoid hacking into a honeypot.
How to Hack Databases: Extracting Data from Online Databases Using Sqlmap
Welcome back, my greenhorn hackers! In a previous tutorial on hacking databases, I showed you how to find online databases and then how to enumerate the databases, tables, and columns. In this guide, we'll now exfiltrate, extract, remove—whatever term you prefer—the data from an online database.
How To: Discover Hidden Subdomains on Any Website with Subfinder
When approaching a target, having a precise and detailed plan of attack is absolutely necessary. One of the main goals is to increase the attack surface since the more opportunities there are for exploitation, the greater the chances of success. Subdomain enumeration is one method used to increase the attack surface, and we'll be using a tool called Subfinder to discover hidden subdomains.
