Study Notes

Introduction to Cybercrime and Threats

Cybercrime is criminal activity targeting or using a computer, computer network, or networked device.
Most cybercrime is financially motivated.
Cybercrime can be committed by individuals or organizations, ranging from novice hackers to highly skilled, organized groups.
Cybercrime includes hacking, social engineering, phishing, malware, ransomware, identity theft, and cyber espionage.
Cybercrime poses significant risks to businesses, governments, and individuals.

Types of Cybercrimes

Malware: Malicious software designed to damage or disrupt computer systems.
Phishing: Social engineering attacks tricking individuals into revealing sensitive information.
Password Attacks: Exploiting vulnerabilities in systems to gain unauthorized access.
DDoS (Distributed Denial-of-Service): Overloading a network, website, or service with traffic to make it unavailable.
Man-in-the-Middle: Intercepting communications between two parties without their knowledge.
Drive-by Downloads: Malware downloaded automatically when visiting compromised websites.
Malvertising: Malware disguised as legitimate advertisements.
Rogue Software: Software designed to deceive users into revealing sensitive information.

Criminology of Cybercrime

Criminology is the scientific study of crime, behavior, and the criminal justice system.
Criminologists use various theories—Routine Activity Theory, Social Learning Theory, and Victim Participation Theory—to understand cybercrime.
Routine Activity Theory investigates the intersection of motivated offenders, suitable targets, and the absence of capable guardians.
Social Learning Theory explains how criminal behavior is learned through observation, retention, reproduction, and motivation.
Victim Participation Theory examines how victims' actions or inactions contribute to their victimization.
Cybercrime's characteristics differ from traditional crime, with a lack of robust evidence regarding actors in cyberspace.

Cybercrime Investigation

Cybercrime investigations involve identifying, tracking, and prosecuting those performing illegal activities digitally.
Investigations utilize digital forensics for evidence collection and analysis.
Techniques include performing background checks, gathering information, tracking individuals, and using specialized tools and techniques.
Obstacles include anonymity, the use of proxy servers, and the need for international cooperation.
Investigators need legal expertise and technical skills.

Cybercrime Laws

Cyber laws provide a legal framework for activities conducted in cyberspace, addressing issues like data privacy, intellectual property, cybercrime, and electronic commerce.
Cyber security laws mandate information security measures.
Cybercrime laws define the offenses and penalties for illegal activities like hacking, identity theft, and cyber-terrorism.
Cyber crime laws address issues like the harmonization of national laws and the role of law enforcement.

Corporate Data

Corporate data encompasses structured, unstructured, and semi-structured data.
Valuable data includes financial statements, sales reports, customer databases, employee records, and market research data.
Hackers often target personally identifiable information (PII) such as social security numbers and financial details, and digital infrastructure.

Cyber Threats

Cybercriminals may use various means— such as phishing, malware, or other social engineering techniques—to attain their goals.
Nation-state actors, or a nation's government-connected groups, conduct activities like cyber espionage.
Insider threats originate from individuals within an organization who misuse their access.
Hacktivists use hacking as a form of protest.
Advanced persistent threats (APTs) are highly organized and sophisticated groups.
Script kiddies are inexperienced or amateur hackers using automated or pre-programmed tools.

Cyber Policy

A security policy defines and outlines rules, expectations, and methods for maintaining confidentiality and integrity of data.
Effective security policies include a clear purpose, scope, and commitment from senior management.
Policies are organized into program, issue-specific, and system-specific types.
Policy elements include clear objectives, scope, management commitment, realistic policies, and up-to-date information.

Denial of Service (DoS) Attacks

A DoS attack floods a server with data packets to overwhelm its resources, making the service unavailable.
Classifications include volume-based (bandwidth attacks), protocol attacks (resource starvation), and application layer attacks.
Types of DoS attacks include UDP floods, SYN floods, ICMP floods, Ping of Death, Teardrop, Land, and Nuke attacks.
DDoS attacks involve multiple computers launching an attack, making them harder to defend against.

Cyber Threat Modeling

Cyber threat modeling is the systematic identification and mitigation process of vulnerabilities
It helps to determine the possible threats to assets, how and when they could be mitigated
Benefit includes early identification of potential threats, improved understanding of security posture, cost effective risk management, and enhanced collaboration

Cyber Kill Chain

The Cyber Kill Chain is a framework for understanding how cyber attacks occur
It consists of stages such as Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control, and Actions on Objectives
Each stage offers a place to implement security measures to prevent attackers
The kill chain is used to identify vulnerabilities, mitigate security risks, and anticipate threats
