Study Notes

Cyberattack Overview

Cyberattacks represent deliberate endeavors undertaken by malicious actors, including cybercriminals and hackers, to infiltrate and disrupt computer networks or systems. These actions typically involve employing sophisticated techniques to breach security measures and gain unauthorized access for nefarious purposes.
Targets range from individual users to enterprises and governments.
Common goals include altering, stealing, destroying, or exposing sensitive information.
For organizations, hackers aim to access valuable resources, such as intellectual property, customer data, or payment details.

Common Types of Cyberattacks

Malware
- Malicious software designed to harm computers, networks, or servers.
- Encompasses various forms, including ransomware, trojans, spyware, viruses, worms, keyloggers, bots, and cryptojacking.
Denial-of-Service (DoS) Attacks
- Floods a network with false requests, disrupting business operations.
- Users experience interruptions in accessing email, websites, and online accounts.
- Differences between DoS and Distributed Denial-of-Service (DDoS): DoS attacks originate from a single system; DDoS attacks come from multiple systems and are harder to combat.
Phishing
- Utilizes email, SMS, phone, and social media to trick victims into sharing sensitive information.
- Victims may inadvertently download malicious files that install viruses.
Spoofing
- Cybercriminals impersonate trusted sources to gain access to systems or devices.
- The goal is to steal information, extort money, or install harmful software through deception.
Identity-Based Attacks
- Occur when an attacker uses stolen credentials to masquerade as a legitimate user.
- Hard to detect as the attacker mimics typical user behavior.
Code Injection Attacks
- Involve injecting malicious code into a vulnerable system to alter its function.
- Can take several forms targeting application vulnerabilities.
Supply Chain Attacks
- Target trusted third-party vendors vital to the supply chain.
- Software attacks involve injecting malicious code into applications to affect all users, while hardware attacks compromise physical components.
Social Engineering Attacks
- Manipulate human psychology to deceive individuals into providing sensitive information or access.

Summary of Cyberattack Impact

Cyberattacks can result in significant financial losses, operational disruptions, and theft of sensitive information across various sectors.
Prevention and mitigation strategies are essential to counter these threats effectively.
