Computer Hacking And Ransomware Attacks
Computer hacking and ransomware attacks are cybercrimes targeting digital systems for financial gain, espionage, disruption, or data theft. These offences are increasingly relevant due to widespread use of digital infrastructure in business, government, and personal life.
Key Types of Offences
Computer Hacking – unauthorized access to computer systems, networks, or data.
Ransomware Attacks – malware encrypting victims’ files and demanding payment for decryption.
Data Theft / Identity Theft – stealing sensitive or personal information.
Denial-of-Service (DoS) / Distributed Denial-of-Service (DDoS) – disrupting network services intentionally.
Malware Deployment – spreading viruses, worms, or trojans to cause damage or gain access.
Cyber Espionage – accessing confidential or classified data for political or financial motives.
Legal Principles
Offences are generally criminalized under cybercrime or computer misuse laws.
Intent and unauthorized access are central to proving hacking.
Ransomware attacks can involve multiple offences: extortion, data theft, computer misuse, and money laundering.
Jurisdictions may allow extradition for cybercrime, given its transnational nature.
Both individuals and organizations (for negligence or inadequate cybersecurity) can face liability.
