Concept: Cybercrime refers to illegal activities carried out using computers, networks, or the internet. These crimes involve unauthorized access, data theft, financial fraud, or disruption of digital systems. Cybercriminals exploit vulnerabilities in computer systems to gain access to sensitive information or damage digital resources. Definition of Cybercrime: Cybercrime is any criminal activity in which a computer, network, or internet-connected device is used as a tool, target, or both. 1. Hacking Hacking is the act of gaining unauthorized access to a computer system or network in order to steal, modify, or destroy data. Characteristics:

• Unauthorized access to computer systems.
• Data theft or manipulation.
• Can lead to privacy breaches and system damage.

Example: A hacker breaking into a company's database to steal confidential customer information. 2.

• Encrypts files or blocks access to systems.
• Demands money to unlock data.
• Often spreads through malicious attachments or infected websites.
