How To: Writing 64-Bit Shellcode - Part 1 (Beginner Assembly)

In this simple tutorial you will be shown step-by-step how to write local shellcode for use on 64-Bit Linux systems. Shellcode is simple code, usually written in assembly that is used as payload in exploits such as buffer overflow attacks.

A few simple changes can be made to a Kali Linux desktop to make it safer to use in this environment.

How To: Use Maltego to Target Company Email Addresses That May Be Vulnerable from Third-Party Breaches

The easiest way around a security policy is to find users who don't follow it.

Apple introduced third-party keyboards back in iOS 8, and swipe-input options like Gboard, SwiftKey, and Swype made typing on an iPhone one-handed much easier. Even better, apps like Word Flow moved the keyboard to the side of the iPhone, so there was less thumb-stretching.
