Understanding Malware

The video tutorial provides an in-depth look at various types of malware, including viruses, Trojan horses, rootkits, spyware, ransomware, and cryptomining software. It explains how these malicious programs operate, the vulnerabilities they exploit, and the potential damage they can cause to computer systems. The tutorial also emphasizes the importance of keeping systems updated with security patches and using antivirus software to protect against these threats.

What is one of the primary reasons for keeping your operating system and applications up to date?

• To increase storage space

• To prevent malware from exploiting vulnerabilities

• To ensure compatibility with new software

• To improve system performance

What is a Trojan horse in the context of computer malware?

• A software that appears legitimate but is malicious

• A program that encrypts your files

• A type of virus that replicates itself

• A tool used for mining cryptocurrency

Why are rootkits particularly difficult to detect?

• They replicate themselves quickly

• They disguise themselves as system files

• They embed themselves deep in the operating system

• They are always encrypted

What is a key characteristic of a computer virus?

• It monitors keystrokes

• It hides in the boot sector

• It encrypts files on the system

• It requires human intervention to spread

How does a boot sector virus operate?

• By monitoring user activity

• By hiding in the system's kernel

• By loading itself from the boot sector every time the system starts

• By encrypting files on the system

What is the primary function of spyware?

• To mine cryptocurrency

• To replicate itself across networks

• To encrypt files on the system

• To monitor and steal personal information

What is a keylogger?

• A type of virus that replicates itself

• A tool used for mining cryptocurrency

• A software that records keystrokes

• A program that encrypts files

What does ransomware do to a victim's files?

• Uses them for mining cryptocurrency

• Deletes them permanently

• Encrypts them and demands payment for decryption

• Monitors and logs keystrokes

How can you recover from a ransomware attack without paying the ransom?

• By restoring from a known good backup

• By updating your antivirus software

• By using a keylogger

• By running a system performance check

What is the primary goal of crypto mining malware?

• To use the system's resources for mining cryptocurrency

• To replicate itself across networks

• To monitor user activity

• To encrypt files on the system
