Unit 1: Introduction to Cybercrime
1. Classification of Cybercrime

Cybercrime can be classified in several ways, primarily based on the target of the crime or the nature of the offense.

Classification Based on the Target:

  • Crimes Against Individuals: These crimes directly target a person's privacy or identity. Examples include cyberstalking, cyberbullying, phishing, and identity theft.
  • Crimes Against Property: These offenses involve the theft or damage of digital property. This category includes hacking, malware attacks (like viruses and ransomware), financial fraud, and cybersquatting.
  • Crimes Against Organizations: These are attacks aimed at businesses, governments, or other organizations. Common examples are large-scale data breaches, ransomware attacks, and cyber extortion.
  • Crimes Against Society: These crimes have a broad impact on the public and national stability. This includes cyberterrorism, cyber warfare, and the distribution of illegal content like child pornography.

Classification Based on the Type of Offense:

  • Financial Cybercrimes: Crimes motivated by illicit financial gain.
  • Identity-related Cybercrimes: Offenses involving the theft and misuse of personal information.
  • Content-related Cybercrimes: Involve the distribution of illegal or harmful content online.
  • Crimes against Computer Systems: Attacks that target the confidentiality, integrity, or availability of data and networks.
2. Financial Crime and Its Types

A financial crime is any illegal activity where an individual or group unlawfully obtains financial assets like money or property. It's often called "white-collar crime" because it is typically non-violent and targets assets rather than people.

Financial crimes generally fall into two categories:

  1. Illegally generating financial benefits for oneself through deceptive means.
  2. Committing an initial crime (like money laundering) to enable another crime for financial gain.

Common Types of Financial Crime:

  • Fraud: Any activity using deceit to gain a financial advantage.
  • Money Laundering: Disguising the origins of illegally obtained money.
  • Terrorist Financing: Providing financial support to terrorist groups.
  • Embezzlement: Illicitly using funds that one has been entrusted with.
  • Corruption and Bribery: Abusing a position of power for financial gain, often involving illegal payments (bribes).
  • Tax Evasion: Intentionally underpaying or not paying taxes.
  • Insider Trading: Using confidential information to gain an unfair advantage in stock markets.
  • Forgery and Counterfeiting: Illegally altering or creating fake financial assets, like checks or currency.
  • Identity Theft: Stealing someone's personal information to commit financial crimes.
  • Cybercrime: Using digital methods to commit any of the above financial crimes.
3. Cyberstalking and Cyberbullying

a) Cyberstalking

Cyberstalking is the use of the internet and other electronic communications to harass, threaten, or repeatedly monitor an individual, group, or organization. It's a pattern of online behavior designed to instill fear, anxiety, and distress in the victim.

Common forms of cyberstalking include:
  • Sending threatening or harassing emails, texts, or social media messages.
  • Spreading false rumors to damage the victim's reputation.
  • Doxing, which is publishing a victim's private information (like their address or phone number) online.
  • Creating fake profiles to impersonate the victim and harass others.

b) Cyberbullying

Cyberbullying is a form of bullying that takes place using digital technologies like social media, messaging platforms, and gaming platforms. It is repeated behavior aimed at scaring, angering, or shaming the target.

Examples of cyberbullying include:
  • Spreading lies or posting embarrassing photos and videos of someone.
  • Sending hurtful, abusive, or threatening messages.
  • Impersonating someone to send mean messages to others on their behalf.
Key Difference: A key difference between traditional bullying and cyberbullying is that cyberbullying leaves a digital footprint—a record that can be used as evidence to stop the abuse.
4. Hacking: Types and Techniques

Hacking is the act of exploiting vulnerabilities in a computer system or network to gain unauthorized access or control. While "white hat" hacking is done ethically to improve security, it is more commonly associated with malicious intent to steal data, compromise systems, or spread malware.

Common Hacking Types and Techniques:

  • Malware Attacks: Infecting a system with malicious software (viruses, worms, trojans) that can steal data or damage files.
  • Ransomware Attacks: A type of malware that encrypts a victim's files and demands a ransom payment to restore access.
  • Phishing Attacks: Tricking users into revealing sensitive information (like passwords or credit card numbers) by disguising as a trustworthy entity in an email or message.
  • Brute Force Attacks: Systematically trying every possible password combination to gain access to an account.
  • Man-in-the-Middle (MitM) Attacks: Secretly intercepting and altering communications between two parties to steal data.
  • SQL Injection Attacks: Inserting malicious SQL code into a web application's database to steal or manipulate data.
  • Distributed Denial-of-Service (DDoS) Attacks: Overwhelming a server or network with traffic from multiple sources to make it unavailable to users.
5. Impact of Cybercrime

Cybercrime has far-reaching and damaging consequences that affect everyone, from individuals to entire nations.

a) Impact on Individuals

  • Financial Loss: Individuals can lose significant amounts of money through online fraud, phishing scams, and identity theft.
  • Psychological Impact: Victims of cyberstalking, harassment, and cyberbullying often suffer from fear, anxiety, depression, and emotional distress.
  • Privacy Violations: Having personal information stolen in a data breach leads to a loss of privacy and a feeling of vulnerability.
  • Reputational Damage: False information spread online can harm a person's personal and professional reputation.

b) Impact on Organizations

  • Financial Loss: Organizations face enormous costs from data breaches, ransomware payments, and operational downtime.
  • Reputational Damage: A cyberattack can severely damage a company's reputation, leading to a loss of customer trust and business.
  • Operational Disruption: Attacks can shut down business operations, causing lost productivity and revenue.
  • Legal Consequences: Companies may face heavy fines and lawsuits for failing to protect customer data.
  • Loss of Intellectual Property: The theft of trade secrets and proprietary information can give competitors an unfair advantage.

c) Impact on Society

  • Disruption of Critical Infrastructure: Attacks on essential services like healthcare, energy grids, and transportation systems can threaten public safety and well-being.
  • National Security Threats: Cyberattacks can compromise national defense systems and disrupt government services.
  • Erosion of Trust: Widespread cybercrime erodes public trust in digital platforms, institutions, and the digital economy.
  • Economic Impact: The overall cost of cybercrime, including financial losses and cybersecurity spending, places a significant burden on the national economy.
Unit 2: Digital Forensics & Investigation
1. Phases of Cybercrime Investigation

Cybercrime investigations follow a systematic process that is typically broken down into three main phases:

1. Incident Response and Preparation

This is the initial phase that begins when a cyber incident is detected. The key actions include detecting the breach, containing the damage to prevent it from spreading, and planning the investigation by allocating resources and setting timelines.

2. Digital Evidence Collection

In this phase, investigators gather and secure evidence from the affected systems. This involves identifying all relevant devices and networks, collecting data by creating forensic images of drives and copying files, and preserving the evidence's integrity through proper handling and storage procedures.

3. Analysis and Reconstruction

The final phase involves examining the collected evidence to understand what happened. Investigators use forensic tools for examination, analyze the data to reconstruct the timeline of the attack, and create a final report documenting their findings for legal or internal purposes.

2. Types of Digital Evidence

Digital evidence is any information of probative value that is stored or transmitted in a digital form. It can be categorized in several ways:

Data from Electronic Devices

This is the most common category and includes:

  • Files and Documents: Word documents, spreadsheets, PDFs, etc.
  • Communications: Emails, text messages, and instant messenger chats.
  • Web Activity: Browser history, search queries, and online transaction records.
  • Multimedia: Photos, videos, and audio recordings.
  • System Data: Databases, system logs, and application logs that record events.
  • Metadata: Data about data, such as file creation dates, author information, and modification times.

Data from Networks and the Cloud

Evidence isn't just on local devices. It also includes:

  • Cloud Storage: Files and backups stored on services like Google Drive or Dropbox.
  • Network Traffic: Captured data of website visits and data transfers.
  • Social Media: Posts, private messages, and user profile information.

Volatile vs. Non-Volatile Evidence

Volatile Data

This is temporary evidence that is lost when the device is powered off. Examples include data in RAM, running processes, active network connections, and clipboard content. It's crucial for understanding the system's live state.

Non-Volatile Data

This is permanent data that remains even when the device is powered off. It includes files stored on hard drives (HDDs), solid-state drives (SSDs), and USB flash drives. It provides historical evidence of past events.

3. Evidence Collection and Preservation Methods

a) Collection Methods

Collection is the process of gathering digital evidence from various sources. The method used must ensure the evidence remains unaltered. Key methods include:

  • Forensic Imaging: This involves creating an exact, bit-for-bit copy of an entire storage device (like a hard drive). This captures all data, including deleted files and fragments, while leaving the original device untouched.
  • Logical Acquisition: This method involves collecting only specific active files from a device. It's faster than a full image but doesn't capture deleted data.
  • Network Packet Capture: This technique records data traffic moving across a network, which helps in analyzing communication patterns and data flow.
  • Cloud Forensics: This involves specialized methods to extract data from cloud services and storage, which requires legal authorization and cooperation from the service provider.
  • Mobile Device Forensics: This uses specific tools and techniques to acquire data from smartphones and tablets, including call logs, messages, app data, and location history.

b) Preservation Methods

Preservation is the act of protecting the integrity of collected evidence to ensure it's usable in legal proceedings. It's a continuous process that involves:

  • Forensic Imaging: As a collection method, it is also the primary preservation technique because it leaves the original evidence in its pristine state. Analysis is performed only on the created image.
  • Maintaining the Chain of Custody: This is the most critical aspect of preservation. It is a detailed log that documents the chronological history of the evidence, including who collected it, who had access to it, and where it was stored at all times.
  • Data Integrity Verification: Using hashing algorithms like MD5 or SHA-256 to create a unique digital fingerprint of the evidence. This hash is calculated upon collection and later verified to prove that the evidence has not been tampered with.
  • Proper Documentation: Thoroughly recording every step of the collection and handling process is essential for demonstrating that proper procedures were followed.
4. Analysis of Digital Evidence

The analysis of digital evidence is done by examining the collected data to uncover, interpret, and document information relevant to the investigation. It's not a single process but a range of specialized fields:

  • Computer Forensics: Analyzing data from computers and hard drives to recover deleted files, examine system logs, and reconstruct user activity.
  • Network Forensics: Monitoring and analyzing network traffic to identify security breaches, track unauthorized access, or understand how an attack occurred.
  • Mobile Device Forensics: Extracting and analyzing data from smartphones and tablets, such as call logs, text messages, GPS data, and social media activity.
  • Memory Forensics: Analyzing a computer's RAM (volatile memory) to find runtime information that isn't stored on the hard drive, which is crucial for malware investigations.
  • Malware Forensics: Reverse engineering malicious software to understand its purpose, origin, and impact.
  • Cloud Forensics: Examining data stored in cloud environments, which presents unique challenges related to jurisdiction and data access.
5. Presentation of Digital Evidence

Presenting digital evidence in a legal setting requires careful preparation to ensure it is understood and accepted by the court. It can be presented in two main ways:

1. Substantive Evidence

The evidence is presented to directly prove a fact. For example, an email containing a threat is substantive evidence of the threat being made.

2. Demonstrative Evidence

The evidence is used to illustrate or clarify other testimony or evidence. For example, using GPS data to create a map that shows a suspect's movements.

Key Requirements for Presentable Evidence:

  • Authentication: It must be proven that the evidence is genuine and has not been tampered with. This is where the chain of custody and hash values are critical.
  • Relevance and Admissibility: The evidence must be directly relevant to the case and meet all legal standards for admissibility in court.
  • Clarity: The evidence must be presented in a way that is clear and understandable to non-technical individuals, such as a judge or jury. This often involves expert testimony to explain the significance of the findings.
6. Chain of Custody and Admissibility

a) Chain of Custody

The chain of custody is the chronological, documented record of the handling of evidence. Its purpose is to prove the integrity of the evidence by showing that it has been secured and handled properly from the moment of collection to its presentation in court.

A proper chain of custody log must include:
  • Who collected the evidence.
  • The date and time of collection.
  • A detailed description of the evidence.
  • The names of everyone who handled the evidence.
  • The dates and times of any transfers of custody.
  • Where the evidence was stored.
A break in the chain of custody can raise doubts about the evidence's authenticity and may lead to it being ruled inadmissible.

b) Admissibility

Admissibility refers to whether a piece of evidence is legally acceptable and can be presented in court. For evidence to be admissible, it must be:

  • Relevant: It must have a logical connection to the facts of the case.
  • Authentic: It must be proven to be what it purports to be. A strong chain of custody is essential for establishing authenticity.
  • Reliable: The method used to collect and analyze the evidence must be reliable and sound.
If the integrity of the evidence is questionable (for example, due to a broken chain of custody), a judge may rule it inadmissible, meaning it cannot be considered in the case.
Unit 3: Legal Frameworks
1. IT Act 2000 (India) and Its Amendments

The Information Technology Act, 2000 (IT Act) is the primary law in India that provides a legal framework for electronic transactions and cybercrimes. Its main purpose is to give legal recognition to electronic records and digital signatures, thereby facilitating e-commerce, e-governance, and a secure digital environment.

Key Features of the IT Act, 2000:

  • Legal Recognition: It equates electronic records and digital signatures with physical documents and handwritten signatures.
  • E-Governance: It enables the electronic filing of documents with government bodies.
  • Cybercrime Provisions: It defines various cybercrimes like hacking and data theft and prescribes punishments for them.
  • Regulatory Bodies: It established the Controller of Certifying Authorities (CCA) to regulate digital signatures and the Cyber Appellate Tribunal to handle disputes.

Major Amendments:

The Act has been updated to keep pace with changing technology, most notably through two key amendments:

The 2008 Amendment

This was a significant overhaul that introduced provisions for:

  • Cyber Terrorism (Section 66F).
  • Data Protection (Section 43A), making companies liable for negligence in securing sensitive personal data.
  • Intermediary Liability (Section 79), defining the responsibilities of platforms like ISPs and social media companies.
  • It also introduced Section 69A, giving the government power to block public access to online information. (Note: Section 66A, which dealt with offensive messages, was added in this amendment but was later struck down by the Supreme Court in 2015).
The 2023 Amendment

This recent amendment focused on refining and updating definitions and terminology within the act.

2. Relevant Sections of IPC and CrPC for Cyber Offenses

While the IT Act is the special law for cybercrimes, several sections of the Indian Penal Code (IPC) and the procedural framework of the Code of Criminal Procedure (CrPC) are also applied.

Relevant Laws Defining Offenses:

Information Technology Act (IT Act):
  • Section 66: Deals with hacking and computer-related offenses.
  • Section 66C: Covers identity theft.
  • Section 66D: Pertains to cheating by impersonation using a computer.
  • Section 66F: Addresses the serious crime of cyber terrorism.
  • Sections 67, 67A, 67B: Prohibit publishing or transmitting obscene or sexually explicit material, especially involving children.
Indian Penal Code (IPC):
  • Section 354D: Addresses cyberstalking.
  • Sections 419 & 420: Deal with cheating and fraud, which can include online scams.
  • Section 292: Prohibits the sale or distribution of obscene materials, which can extend to electronic forms.

Procedural Law for Investigation (CrPC):

The CrPC does not define cybercrimes but provides the procedure for their investigation and prosecution. Key relevant sections include:

  • Sections 154-157: Govern the lodging of a First Information Report (FIR) to initiate a police investigation.
  • Sections 41-41D: Outline the procedures for arresting a person in connection with a crime.
  • Section 91: Empowers a court to summon necessary documents or digital records from service providers.
  • Section 164: Covers the recording of statements before a Magistrate to ensure their admissibility as evidence.
  • Section 173: Deals with the filing of the final police report (charge sheet) after an investigation is complete.
3. International Legal Frameworks

International legal frameworks are the set of rules, principles, and processes that govern the relationships and interactions between countries and other international actors. They are essential for maintaining global order, promoting cooperation, and resolving cross-border disputes.

Categories of International Legal Frameworks:

  • Public International Law: Governs the relationships between states (e.g., treaties, diplomatic relations, laws of war).
  • Private International Law: Deals with legal disputes between private individuals or entities from different countries, determining which country's laws should apply.
  • Supranational Law: Law created by international organizations (like the European Union) that is binding on their member states.

Primary Sources of International Law:

The primary sources of international law include treaties, customary practices followed by states, general principles of law recognized by nations, and judicial decisions from international courts.

4. Role of GDPR in Preventing Cybercrime

The General Data Protection Regulation (GDPR), an EU law, plays a significant indirect role in preventing cybercrime by enforcing strict data protection standards. While its primary goal is privacy, its requirements inherently bolster cybersecurity.

How GDPR Helps Prevent Cybercrime:

  • Mandates Strong Security: GDPR requires organizations to implement "appropriate technical and organisational measures" to ensure data security (integrity and confidentiality). This forces companies to adopt robust cybersecurity practices like encryption and access control, making it harder for criminals to breach systems.
  • Reduces the Attack Surface: The principle of data minimization requires companies to collect and store only the data that is absolutely necessary. Less stored data means there is less for cybercriminals to steal in the event of a breach, making the target less attractive.
  • Creates a Powerful Deterrent: The penalties for non-compliance are severe—fines of up to €20 million or 4% of a company's annual global turnover. This massive financial risk provides a strong incentive for organizations to invest heavily in cybersecurity measures to avoid breaches, thus preventing cybercrime.
  • Enforces Accountability: GDPR forces organizations to be accountable for the data they handle, including conducting data protection impact assessments and reporting breaches promptly. This culture of accountability leads to better overall security posture.
5. Budapest Convention

The Budapest Convention on Cybercrime is the first and only legally binding international treaty created to address cybercrime. It serves as a comprehensive framework that encourages international cooperation and helps countries harmonize their national laws to fight computer-facilitated crime more effectively.

Key Aspects of the Convention:

  • Harmonization of Laws: It requires member countries to criminalize a specific list of offenses, including illegal access (hacking), data interference, computer-related fraud, and online child pornography.
  • Procedural Tools: It establishes procedures for law enforcement to collect electronic evidence effectively.
  • International Cooperation: It creates a 24/7 network for rapid cooperation among member nations, allowing them to share information and request assistance in cross-border cybercrime investigations.
India's Position: It's important to note that India is not a party to the Budapest Convention.
6. Recent Judicial Decisions

In the context of international law, judicial decisions, especially from bodies like the International Court of Justice (ICJ), are a crucial source for interpreting and developing legal frameworks that govern states. Recent decisions highlight evolving global challenges and the role of international courts.

Key Impacts and Trends from Recent Judicial Decisions:

  • Addressing Global Issues: Courts are increasingly being asked to rule on pressing global issues. A notable example is the litigation brought by Small Island States to the ICJ regarding the climate crisis, seeking to clarify the legal obligations of nations in protecting the environment.
  • Enforcement Challenges: Recent cases have underscored the difficulty in enforcing ICJ decisions, as the court lacks a dedicated enforcement mechanism, raising concerns about state compliance.
  • Influence on Domestic Law: Decisions from international courts can influence national laws. The Filartiga v. Pena-Irala case, for example, demonstrated how customary international law (unwritten rules that become binding on states) can be incorporated into a country's domestic legal system to address human rights violations.
