Step 1: Identifying the Category of Hacking:
The scenario describes Ethical Hacking (also known as White-Hat Hacking or penetration testing).
• Context: Murugan has obtained explicit, legal authorization from the network owner to probe systems for security gaps.
• Purpose: His objective is defensive. He works to identify security vulnerabilities, document findings, and patch security holes before malicious actors (Black-hat hackers) can exploit them.
Step 2: Evaluating the Legal Status:
No, this activity is not considered a cybercrime.
• Lack of Malicious Intent: Cybercrimes require malicious intent (mens rea) and unauthorized action.
• Legal Authorization: Because Murugan is working with authorization under a formal contract, his actions are entirely legal and act as a critical cyber-defense practice for organizations.
