According to geeksforgeeks.org, cyber attacks are malicious attempts to gain unauthorized access to computer systems, networks or data, and they are carried out to steal sensitive information, disrupt services or damage digital systems.

Geeksforgeeks.org reported that malware refers to malicious software designed to damage, disrupt or gain unauthorized access to computer systems or take control of a system without the user's knowledge. The same source defined a phishing attack as a social engineering technique where attackers trick users into revealing sensitive information such as passwords, banking details or login credentials.

Geeksforgeeks.org described ransomware as a type of malware that encrypts a victim’s files or locks their computer system, and noted that the attacker demands a ransom payment to restore access to the files.

Geeksforgeeks.org explained that a DDoS attack attempts to make a website or online service unavailable by flooding it with massive traffic from multiple systems, and that SQL Injection is a web application attack where attackers insert malicious SQL commands into input.
