HackThisSite.org (HTS) is an online hacking and security website founded by Jeremy Hammond. The site is maintained by members of the community after he left the organization. [1] It aims to provide users with a way to learn and practice basic and advanced "hacking" skills through a series of challenges in a safe and legal environment.
In hacking, a wargame (or war game) is a cyber-security challenge and mind sport in which the competitors must exploit or defend a vulnerability in a system or application, and/or gain or prevent access to a computer system. [1] [2] [3]
There are two types of Footprinting that can be used: active Footprinting and passive Footprinting. Active Footprinting is the process of using tools and techniques, such as performing a ping sweep or using the traceroute command, to gather information on a target.

[1] Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, [2] challenge, recreation, [3] or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.
In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability.It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.

In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
This anti-shoulder surfing security method was developed based on survey results of users' affinity of choices, [11] and through observation on the way children paint pictures. The resulting mechanism was developed from the survey of user choices, and the outcome created three input schemes named Swipe Scheme, Colour Scheme, and Scot Scheme.
