Question 1

What is the term used to describe unwanted software that installs along with the application software that you originally downloaded and installed?
A) RAT
B) PUP
C) Evil Twin
D) Adware

Accepted Answer

PUP stands for Potentially Unwanted Program, which refers to software that is not necessarily malicious, but can install without the user's knowledge or consent and cause annoyances or harm to the system. Adware is a type of PUP that displays unwanted ads, while RAT (Remote Access Trojan) is a type of malware that allows unauthorized access to a computer. Evil Twin is a type of Wi-Fi attack where a fake network is created to intercept user data.

Question 2

A ______________ exploit usually begins with a virus warning and an offer to disinfect the infected device.
A) rogue antivirus
B) virus hoax
C) RAT
D) backdoor

Accepted Answer

The scenario described matches the characteristics of a rogue antivirus exploit, which tricks users into downloading fake antivirus software that claims to clean their infected system but actually installs malware.

Question 3

The most common types of PUPs and PUAs are toolbars and alternative browsers.

Accepted Answer

Toolbars and alternative browsers are indeed among the most common types of potentially unwanted programs (PUPs) and potentially unwanted applications (PUAs). Other examples of PUPs and PUAs include adware, spyware, system optimizers, and fake antivirus programs.

Question 4

______________________ increases security by verifying identity based on more than just a password or PIN.
A) RAT
B) A hash value
C) Two-factor authentication
D) HTTPS

Accepted Answer

Two-factor authentication requires a user to provide two forms of identification before being granted access, such as a password and a code sent to their phone, making it more secure than just using a password or PIN.

Question 5

A dropper installs a malicious program on a device, and it works with an entire program.Code injection inserts a segment of malicious code into another program.It carries only a short segment of code rather than an entire program.

Accepted Answer

Droppers typically install a complete malicious program, while code injection involves inserting only a segment of malicious code into an existing program.

Question 6

Antivirus software's on-access scanning has a high probability of identifying zero-day exploits.

Accepted Answer

On-access scanning in antivirus software is designed to detect known threats by comparing file signatures or behavior patterns against a database of known malware. Zero-day exploits are previously unknown vulnerabilities that attackers exploit before they are discovered by antivirus vendors or security researchers. Therefore, the probability of identifying zero-day exploits through on-access scanning is low. However, some antivirus software may use behavioral analysis or heuristics to detect suspicious activity, which could potentially identify zero-day exploits.

Question 7

____________ is a service offered by Google that checks URLs against a list of suspicious Web site URLs.
A) Personal firewall
B) Safe Browsing
C) Heuristic analysis
D) SmartScreen Filter

Accepted Answer

Safe Browsing is a service offered by Google that checks URLs against a list of suspicious Web site URLs. This service helps protect users from phishing, malware, and other harmful websites.

Question 8

Pharming attacks carried out by domain name system (DNS) spoofing can be detected by antivirus software or spyware removal software.

Accepted Answer

Antivirus or spyware removal software typically does not detect DNS spoofing, as it involves redirecting traffic at the network level rather than installing malicious software on a device.

Question 9

Microsoft uses a service called Safe Browsing to alert users about sites to avoid.

Accepted Answer

Microsoft uses a service called SmartScreen, not Safe Browsing, to alert users about potentially malicious websites. Safe Browsing is a service provided by Google.
