Which of the following can be performed with software or hardware devices in order to record
everything a person types using his keyboard?

A.
Warchalking

B.
Keystroke logging

C.
War dialing

D.
IRC bot

Explanation:

Keystroke logging is a method of logging and recording user keystrokes. It can be performed with
software or hardware devices. Keystroke logging devices can record everything a person types
using his keyboard, such as to measure employee’s productivity on certain clerical tasks. These
types of devices can also be used to get usernames, passwords, etc.
Answer option C is incorrect. War dialing is a technique of using a modem to automatically scan a
list of telephone numbers, usually dialing every number in a local area code to search for
computers, BBS systems, and fax machines. Hackers use the resulting lists for various purposes,
hobbyists for exploration, and crackers (hackers that specialize in computer security) for password
guessing.
Answer option A is incorrect. Warchalking is the drawing of symbols in public places to advertise
an open Wi-Fi wireless network. Having found a Wi-Fi node, the warchalker draws a special
symbol on a nearby object, such as a wall, the pavement, or a lamp post. The name warchalking
is derived from the cracker terms war dialing and war driving.
Answer option D is incorrect. An Internet Relay Chat (IRC) bot is a set of scripts or an independent
program that connects to Internet Relay Chat as a client, and so appears to other IRC users as
another user. An IRC bot differs from a regular client in that instead of providing interactive access
to IRC for a human user, it performs automated functions.
