Certified Ethical Hacker -WGU C701Questions and Answers 100% Solved
Crypter ✔✔It is a software program that can conceal the existence of malware. Attackers use this
software to elude antivirus detection. It protects malware from reverse engineering or analysis,
thus making it difficult to detect by security mechanisms.
Downloader ✔✔It is a type of Trojan that downloads other malware (or) malicious code and files
from the Internet to a PC or device. Usually, attackers install a downloader when they first gain
access to a system.
Dropper ✔✔It is a covert carrier of malware. Attackers embed notorious malware files inside
droppers, which can perform the installation task covertly. Attackers need to first install the
malware program or code on the system to execute the dropper. The dropper can transport
malware code and execute malware on a target system without being detected by antivirus
scanners.
Exploit ✔✔It is the part the malware that contains code or a sequence of commands that can take
advantage of a bug or vulnerability in a digital system or device. Attackers use such code to
breach the system's security through software vulnerabilities to spy on information or to install
malware. Based on the type of vulnerabilities abused, exploits are categorized into local exploits
and remote exploits.
,Injector ✔✔This program injects exploits or malicious code available in the malware into other
vulnerable running processes and changes the method of execution to hide or prevent its
removal.
Obfuscator ✔✔It is a program that conceals the malicious code of malware via various
techniques, thus making it difficult for security mechanisms to detect or remove it.
Packer ✔✔This software compresses the malware file to convert the code and data of the
malware into an unreadable format. It uses compression techniques to pack the malware.
Payload ✔✔It is the part of the malware that performs the desired activity when activated. It may
be used for deleting or modifying files, degrading the system performance, opening ports,
changing settings, etc., to compromise system security.
Malicious Code ✔✔This is a piece of code that defines the basic functionality of the malware
and comprises commands that result in security breaches. It can take the following forms:
o Java Applets o ActiveX Controls o Browser Plug-ins o Pushed Content
APT (Advanced Persistent Threat) ✔✔a type of network attack whereby an attacker gains
unauthorized access to a target network and remains in the network without being detected for a
long time.
, Objectives (APT) ✔✔The main objectives of any APT attack is to repeatedly obtain sensitive
information by gaining access to the organization's network for illegal earnings. Another
objective of an APT may be spying for political or strategic goals.
Timeliness (APT) ✔✔It refers to the time taken by an attacker from assessing the target system
for vulnerabilities to exploiting them to gain and maintain access to the target system.
Resources (APT) ✔✔It is defined as the amount of knowledge, tools, and techniques required to
perform an attack. APT attacks are more sophisticated attacks performed by highly skilled
cybercriminals, and they require considerable resources.
Risk Tolerance (APT) ✔✔It is defined as the level up to which the attack remains undetected in
the target network. APT attacks are well planned and executed with proper knowledge of the
target network, which helps them remain undetected in the network for a long time.
Skills and Methods (APT) ✔✔These are the methods and tools used by attackers to perform a
certain attack. The methods used for performing the attack include various social engineering
techniques to gather information about the target, techniques to prevent detection by security
mechanisms, and techniques to maintain access for a long time.
Actions (APT) ✔✔APT attacks follow a certain number of technical "actions" that make them
different from other types of cyber-attacks. The main objective of such attacks is to maintain
their presence in the victim's network for a long time and extract as much data as possible.
