How To: Create Custom Wordlists for Password Cracking Using the Mentalist
Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Using the Mentalist, we can generate millions of likely passwords based on details about the target.
How to Hack Wi-Fi: Get Anyone's Wi-Fi Password Without Cracking Using Wifiphisher
While password cracking and WPS setup PIN attacks get a lot of attention, social engineering attacks are by far the fastest way of obtaining a Wi-Fi password. One of the most potent Wi-Fi social engineering attacks is Wifiphisher, a tool that blocks the internet until desperate users enter the Wi-Fi password to enable a fake router firmware update.
How To: Hide a Virus Inside of a Fake Picture
In my last tutorial, I talked about creating a virus inside of a Word Document in the scenario of a mass-mailer attack. In this post, however, I'm going to be covering creating a fake image or screenshot with a meterpreter backdoor hidden inside to be used in a similar scenario. Step 1: Creating the Virus

Android for Hackers: How to Backdoor Windows 10 & Livestream the Desktop (Without RDP)
The Windows 10 desktop and microphone can be livestreamed without using Remote Desktop Protocol (RDP) software and without opening any ports on the target computer. A hacker with low user privileges can monitor and exfiltrate a target's every move and private conversation in real time no matter where they are. Hackers are watching and listening, and there are few ways to protect yourself.
Advice from a Real Hacker: How I Would Build the God's Eye of Furious 7
In the recent hit movie Furious 7, the storyline revolves around the acquisition of a hacking system known as "God's Eye" that is capable of finding and tracking anyone in real time. Both the U.S. spy agencies and an adversarial spy agency (it's not clear who the adversary is, but the location is "beyond the Caucasus mountains," which could imply Russia?) desperately want their hands on this system.
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.
Hack Like a Pro: Linux Basics for the Aspiring Hacker, Part 11 (Apache Web Servers)

How To: Set Up a Wi-Fi Spy Camera with an ESP32-CAM
The ESP32-CAM is a convenient little camera module with a lot of built-in power, and you can turn one into an inconspicuous spy camera to hide in any room. There's only one issue: it does omit a USB port. That makes it a little harder to program, but with an ESP32-based board, FTDI programmer, and some jumper wires, you'll have a programmed ESP32 Wi-Fi spy camera in no time.
How To: Fully Anonymize Kali with Tor, Whonix & PIA VPN
Hacking from a host machine without any form of proxying is reckless for a hacker, and in a penetration test, could lead to an important IP address becoming quickly blacklisted by the target. By routing all traffic over Tor and reducing the threat of malicious entrance and exit nodes with a VPN, we can configure Kali to become thoroughly private and anonymous.
How To: Perform Local Privilege Escalation Using a Linux Kernel Exploit
Getting root is considered the Holy Grail in the world of Linux exploitation. Much like SYSTEM on Windows, the root account provides full administrative access to the operating system. Sometimes even a successful exploit will only give a low-level shell; In that case, a technique called privilege escalation can be used to gain access to more powerful accounts and completely own the system.
