Cybersecurity Offenses And Digital Crime Investigations
I. Introduction: Cybersecurity Offenses and Digital Crime
Cybersecurity offenses involve illegal acts committed using computers, networks, or digital systems, affecting confidentiality, integrity, and availability of data.
Digital crime investigations involve collecting, preserving, analyzing, and presenting electronic evidence for prosecution under cyber laws.
1. Types of Cybersecurity Offenses

Identity Theft & Phishing: Fraudulently acquiring personal data for financial gain (Section 66C, IT Act).
Cyber Stalking and Harassment: Online threats, harassment, or bullying (Section 66A [repealed] and IT Act provisions).
Data Breach and Privacy Violations: Unauthorized access or exposure of sensitive data (Sections 43, 66, IT Act).
Financial Cyber Crimes: Online fraud, phishing, and banking crimes (Sections 66D, 66F IT Act).
Cyber Terrorism: Disruption of critical digital infrastructure (Section 66F IT Act).
