Hacking, unauthorized access, and cyber-intrusion crimes are serious threats in the digital age. Courts in India, the UK, and the USA have established clear jurisprudence emphasizing:
Protection of digital assets
Punishment for unauthorized access
Procedural fairness and proportionality
Cases like Suhas Katti, Shiju & Others, Aaron Swartz, Sony Hack, and Lennon illustrate how laws are applied in practice, highlighting the evolving nature of cyber law globally.
