Comptia Security+ Chapter 2 Malware And Social Engineering Attacks

Front 1

Adware

Back 1

A software program that delivers advertising content in a manner that is unexpected and unwanted by the user

Front 2

Boot sector virus

Back 2

infect computer systems by copying code either to theboot sector on a floppy disk or the partition table on a hard disk. Duringstartup, the virus is loaded into memory. Once in memory, the virus willinfect any non-infected disks accessed by the system.

Front 3

Botnet

Back 3

A logical computer network of zombies under the control of an attacker

Front 4

File types that can be infected?

Back 4

.DOCX, .XLSX Microsoft Office user documents
.EXE Executable program file
.MSI Microsoft installer file
.MSP Windows installer patch file
.SCR Windows screen saver
.CPL Windows Control Panel file
.MSC Microsoft Management Console file
.WSF Windows script file
.REG Windows registry file
.PS1 Windows PowerShell script

Front 5

How are computer attacks different in this day and age?

Back 5

*Availability and simplicity of attack tools

*Universally connected devices

*Greater sophistication of attacks

*Increased speed of attacks

*Faster detection of vulnerabilities

*Delays in security updating

*Weak security update distribution

Front 6

Keylogger

Back 6

Software or a hardware device that captures and stores each keystroke that a user types on the computer’s keyboard.

Front 7

Logic Bomb

Front 8

Back 8

A computer virus that is written in a script known as a macro.

Front 11

Malware that prevents a user’s device from properly operating until a fee is paid

Front 14

Spam

Back 14

Unsolicited email

Front 15

Split infection

Back 15

some viruses split the malicious code itself into several parts (along
with one main body of code), and then these parts are placed at random positions
throughout the program code. To make detection even more difficult these parts may
contain unnecessary “garbage” code to mask their true purpose.

Front 16

Spyware

Back 16

A general term used to describe software that spies on users by gathering information without consent.

Front 17

Watering hole

Back 17

A malicious attack that is directed toward a small group of specific individuals who visit the same website.

Front 18

that can be grouped together as a single command. Often macros are used to automate a complex
set of tasks or a repeated series of tasks.

Front 19

What is a rootkit and how does it work?

Back 19

A set of software tools used by an attacker to hide the actions or presence of other types of malicious software.

is
a set of software tools used to hide the actions or presence of other types of software. This
software can be benign, like playing music CDs, or it can be malicious, such as Trojans,
viruses, or worms. Rootkits do this by changing the operating system to force it to ignore
their malicious files or activity. Rootkits also hide or remove all traces of evidence that may
reveal the malware, such as log entries

Front 20

What is a virus?

Back 20

is malicious computer code that, like its biological
counterpart, reproduces itself on the same computer. Strictly speaking a computer virus replicates
itself (or an evolved copy of itself) without any human intervention.

Front 21

What is an Easter egg?

Back 21

which refers to an undocumented, yet benign hidden feature that launches
by entering a set of special commands, key combinations, or mouse clicks.

Front 22

Worms

Trojan Horse

Aware

Ransomeware

Front 23
