Study Notes

Chapter 4: Understand Information Security Attacks

  • This chapter outlines information security attacks
  • The objectives of the chapter include understanding motives, goals, and objectives of information security attacks, overview of the classification of attacks, and understanding hacking methodologies and frameworks.
  • A cyberattack is an attempt by cybercriminals, hackers, or other digital adversaries to access a computer network or system to alter, steal, destroy, or expose information.
  • Cyberattacks target individuals, enterprises, and governments, often focusing on sensitive company resources like intellectual property (IP), customer data, or payment details.

Motives, Goals, and Objectives of Information Security Attacks

  • Attacks are a result of motive, goal, method, and vulnerability
  • Motives behind information security attacks include disrupting business continuity, stealing information and manipulating data, creating fear and chaos, causing financial loss to the target, and damaging the target's reputation.

Attack Classification

  • Passive Attacks: These attacks do not tamper with data but involve intercepting and monitoring network traffic and data flow. Examples include sniffing and eavesdropping.
  • Active Attacks: These attacks tamper with data in transit or disrupt communication between systems. Examples include denial-of-service (DoS), man-in-the-middle, session hijacking, and SQL injection.
  • Close-in Attacks: These attacks happen when the attacker is physically close to the target system or network. Examples include social engineering tactics like eavesdropping, shoulder surfing, and dumpster diving.
  • Insider Attacks: These attacks involve using privileged access to violate rules or intentionally cause harm to the organization's information systems. Examples include theft of physical devices, planting keyloggers, backdoors, and malware.
  • Distribution Attacks: Attacks where attackers tamper with hardware or software before installation, or while in transit
  • Common Types of Cyberattacks: Malware, Denial-of-Service (DoS) Attacks, Phishing, Spoofing, Identity-Based Attacks, Code Injection Attacks, Supply Chain Attacks, Social Engineering Attacks, Wireless and Mobile Attacks, AI-Powered Attacks.

1. Malware

  • Malware is malicious software designed to do harm to computers, networks, or servers.
  • Common types of malware include ransomware, trojans, spyware, viruses, worms, keyloggers, bots, cryptojacking.
  • Malware attacks utilize software in malicious ways.

2. Denial-of-Service (DoS) Attacks

  • DoS attacks flood a network with false requests to disrupt operations, making resources unavailable.
  • DoS attacks aim at critical business operations.
  • Distributed DoS (DDoS) attacks originate from multiple systems, making them harder to block than single-source DoS attacks.

3. Phishing

  • Phishing is a social engineering attack using emails, SMS, phones, or social media to trick victims into sharing sensitive information (passwords, accounts) or downloading malicious files that install viruses.
  • Types of Phishing include Spear Phishing, Whaling, SMiShing, and Vishing.

4. Spoofing

  • Spoofing is a technique where a cybercriminal disguises themselves to access systems.
  • Types include Domain Spoofing, Email Spoofing, and ARP Spoofing.

5. Identity-Based Attacks

  • These attacks exploit compromised user credentials. It's difficult to detect when an adversary masquerades as a valid user.
  • Common types include Man-in-the-Middle (MITM) Attack, Credential Harvesting, Credential Stuffing, Brute Force Attacks, Dictionary Attacks, Password Spraying, and Pass-the-Hash Attacks

6. Code Injection Attacks

  • Code injection attacks involve inserting malicious code into vulnerable systems to alter their course of action.
  • Common types include SQL Injection, Cross-Site Scripting (XSS), Buffer Overflow, Remote Code Executions, ActiveX Controls and Java controls, and Malvertising.

7. Supply Chain Attacks

  • Software supply chain attacks inject malicious code into applications to infect all users.
  • Hardware supply chain attacks compromise physical components for the same purpose. Modern software depends on many external components (APIs, open source code, proprietary vendors).

8. Social Engineering Attacks

  • Social engineering uses psychological tactics to manipulate people into desired actions or revealing information.
  • Attackers exploit people's willingness to be helpful or prey on people's weaknesses.
  • Common types include Pretexting, Something for Something (Quid pro Quo), Shoulder Surfing, and Dumpster Diving, Impersonation and Hoaxes, Piggybacking and Tailgating, Online, Email, and Web-based Trickery.

9. Wireless and Mobile Attacks

  • Wireless and mobile networks are susceptible to interference, jamming, and attacks such as rogue access points (unauthorized points on a secure network) and RF jamming.
  • Bluejacking and Bluesnarfing (sending unauthorized messages or copying information from other Bluetooth devices).
  • Attacks on WEP and WPA protocols

10. AI-Powered Attacks

  • Adversarial AI/ML attacks manipulate or mislead AI systems, Dark AI exploits vulnerabilities using AI and ML, Deepfakes create realistic but fake media, and AI-generated social engineering uses human-like interactions to collect information.

Hacking Methodologies and Frameworks

  • EC-Council Hacking Methodology: Includes Phases: Planning and Reconnaissance, Scanning, Gaining Access, Maintaining Access, and Clearing Tracks.
  • Cyber Kill Chain Methodology: This method describes the stages of an attack from reconnaissance to actions on objectives. Stages involved are reconnaissance, weaponization, exploitation, delivery, installation, and actions on objectives.
  • Tactics, Techniques, and Procedures (TTPs): These frameworks help describe how attackers are operating.
  • MITRE Attack Framework: This is a knowledge base of adversary tactics and techniques.
  • Diamond Model of Intrusion Analysis: A framework to correlate events in an intrusion, helping analyze and develop mitigation strategies.

Additional Concepts

  • Hacking means exploiting vulnerabilities in systems to gain unauthorized access. It can be used to steal data or disrupt services.
  • Motives behind hacking include thrill, challenge, financial gain, prestige, revenge, and vindictiveness.
