Understanding Cyberattacks

Questions and Answers

What is the primary goal of a cyberattack?

The primary goal of a cyberattack is to access a computer network or system to alter, steal, destroy, or expose information.

What is malware and why is it significant in cyberattacks?

Malware, or malicious software, is any program designed to harm a computer and is significant because it encompasses various attack types like ransomware and viruses.

What distinguishes a Denial-of-Service (DoS) attack from a Distributed Denial-of-Service (DDoS) attack?

A DoS attack originates from a single system, while a DDoS attack comes from multiple systems.

Cyberattack Overview

Cyberattack refers to attempts by cybercriminals to gain unauthorized access to systems for harmful purposes such as data theft or destruction.
Victims of cyberattacks range from individual users to businesses and governments, often targeting sensitive data like intellectual property and customer information.

Common Types of Cyberattacks

Malware:
- Includes harmful programs designed to disrupt, damage, or gain unauthorized access to systems.
- Subtypes encompass ransomware, trojans, spyware, viruses, worms, keyloggers, bots, and cryptojacking.
Denial-of-Service (DoS) Attacks:
- Floods a network with fraudulent requests, disrupting access to services and operations.
- Results in loss of availability rather than data loss; two types include:
  - DoS: originates from a single system.
  - Distributed Denial of Service (DDoS): launched from multiple systems, making it harder to block.
Phishing:
- Uses deceptive communication (emails, SMS, social media) to trick victims into revealing sensitive information or downloading malware.
Spoofing:
- Involves impersonating a trusted source to deceive victims into disclosing information or allowing unauthorized access.
- Can take forms such as email spoofing or website spoofing.
Identity-Based Attacks:
- Occurs when attackers masquerade as legitimate users by compromising their credentials, making detection difficult.
Code Injection Attacks:
- Malicious code is inserted into vulnerable systems to alter their behavior or actions.
Supply Chain Attacks:
- Targets third-party vendors to compromise software or hardware components in the supply chain.
- Software supply chain attacks introduce malicious code into applications affecting all users.
Social Engineering Attacks:
- Manipulates individuals into divulging confidential information through psychological manipulation techniques.
