Question 1

The correct answer is: a: A small business

Small businesses are at a higher risk of a cyberattack because they usually have fewer resources and assets to deal with cyberattacks.

Question 2

The correct answer is: c: Spyware

keylogger is a type of spyware that records all keystrokes the user makes and sends that data to a third party. Keyloggers can record sensitive information, like usernames, passwords and bank details.

Question 3

The correct answer is: d: Firewall

A firewall is a type of computer network security system that restricts internet traffic entering, leaving, and within a private network, not a type of malware.

Options A, B, and C are all examples of malware.

Question 4

The correct answer is: d: Launching a DDoS attack against a specific web server.

With a targeted cyberattack, attackers are launching a cyberattack against a specific individual or organisation. An example of this is launching a DDoS attack against a specific web server to bring it down or make it unresponsive.

Options A, B, and C are examples of untargeted cyberattacks.

Question 5

The correct answer is: b: Ransomware

Ransomware is a type of malware that blocks access to a computer system or files until a sum of money is paid. Ransomware may encrypt your personal files so that they are inaccessible or even completely lock you out of your computer.

Question 6

The correct answer is: b: False

A Trojan horse is a type of malware. It is not a virus because a virus is self-replicating, meaning that it copies itself to spread from one computer to another. A Trojan horse is not self-replicating since it require users to manually download and install it to become infected. Trojan horses don't spread by themselves. Therefore, it is incorrect to say 'Trojan horse virus' or 'Trojan virus'.

Question 7

The correct answer is: a: Attempting the same username and password combination on other websites after an account has been compromised.

This happens after a user account has been compromised and the attacker tries the username and password combination on other websites, particularly very high-traffic well-established sites, in the hope of correctly guessing it. Attackers often collect lists of stolen credentials that were exposed in previous data breaches. Credential stuffing is a reason why it is not recommended to reuse passwords across multiple accounts.

Question 8

The correct answer is: d: All of the above

Options A, B, and C can all minimise the risks of cybercrime.

Question 9

The correct answer is: a: Physically control the keyboard and mouse.

Unauthorised access does not allow hackers to physically control hardware devices.

Options B, C, and D are all examples of things that a hacker can do once they have gained unauthorised access to an electronic account.

Question 10

The correct answer is: b: Unexpected redirects to scam sites or sites filled with ads.

Options A, C, and D are incorrect as they are browser features, not signs of a browser hijacker.

Question 11

The correct answer is: c: It can leave systems vulnerable to security holes.

Riskware describes software that is not strictly malicious, but poses potential security risks due to software incompatibilities, security holes, or legal violations. Riskware is not a type of malware. It is a risky type of software that has the possibility of becoming a threat to a computer and is often downloaded and installed without the user realising that it poses a risk in some way.

Question 12

The correct answer is: d: Exploiting vulnerabilities in telephone systems to gain unauthorised access to restricted telephone services or areas.

Phreaking is the act of exploiting vulnerabilities in telephone systems to gain unauthorised access to restricted telephone services or areas, often to obtain free phone calls, bypass calling restrictions, have calls charged to someone else's account, and even take control of entire telephone networks.

Question 13

The correct answer is: d: All of the above

Options A, B, and C are all examples of ways that viruses and malware spread.

Question 14

The correct answer is: b: No major antiviruses detect it as malicious.

Question 15

The correct answer is: c: Scareware

Rogue security software is a type of scareware that tricks users into thinking they have viruses or malware on their computers when they actually don't and misleads them with fake detections and alerts.
