Correct Answers
Malware
A malicious software
Virus
malicious code that runs without user's knowledge. Viruses require a user action in order to
reproduce and spread
Boot Sector Virus
A virus stored in the first sector of a hard drive and loaded into memory upon boot up. It is
hard to detect
Macros Virus
Virus embedded in a document and executed when the document is opened .
Program Virus
virus that infect an executable or an application
Multipartite Virus
A virus that combines both boot sector and program viruses together by attaching itself to the
boot sector and system files
Encrypted Virus
A virus that uses a cipher to encrypt the content itself to avoid detection by any antivirus
software .
Polymorphic Virus
,An advanced version of an encrypted virus that changes itself everytime its executed by
trying to morph the way the code looks so the sign-based antivirus cant defect it
Metamorphic Virus
A virus that is able to rewrite itself entirely before it attempts to infect a file
Stealth Virus
a category of a virus protecting itself techniques viruses
Armored-
layer of protection to confuse a program or person analyzing it
Easter Egg
not a virus , trick user to infect themselves
Worms
A malware like a virus but it's able to replicate itself without user interaction that cause
disruptions to network traffic, computer activities, and cause a system to crash or slow down
Trojans
A malware disguised as a piece of harmless software to preform desired and malicious
functions to infect a system.
Remote Access Trojan (RAT)

payment is recieved
, Spyware

keylogger that captures keystrokes and take screenshots.
Adware
Displays advertisments based upon its spying
Grayware
mane a computer system to behave improperly
Rootkit
A software aimed to gain administrative level control on a system without detection. The
attacker uses a technique called DLL Injection to maintain their persistent control
DLL Injection
A malicious code inserted into a running process on a Windows machine by taking advantage
of Dynamic Link Libraries that are loaded at running time.
Driver manipulation
An attack that relies on compromising the Kernel-mode device drivers that operate at a
private or system level. A shim is placed between two components to intercept calls and
redirect them
What makes up a rootkit?
DDL Injection and Driver Manipulation
Spam
