Types of cyberattacks

Phishing is a form of social engineering and a scam where attackers deceive people into revealing sensitive information or installing malware such as viruses, worms, adware, or ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim navigates the site, and traverses any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the Federal Bureau of Investigation's Internet Crime Complaint Center reporting more incident

cyber attack disrupting service by overloading the provider of the service

Cybersquatting (also known as domain squatting) is the practice of registering, trafficking in, or using an Internet domain name, with a bad faith intent to profit from the goodwill of a trademark belonging to someone else. The term is derived from "squatting", which is the act of occupying an abandoned or unoccupied space or building that the squatter does not own, rent, or otherwise have permission to use.

creating IP packets using forged IP addresses in headers

cyber attack in which a person or program successfully masquerades as another by falsifying data

creating an email spam or phishing messages with a forged sender identity or address

internet vigilantism tactic

A LAND (local area network denial) is a denial-of-service attack that consists of sending a special poison spoofed packet to a computer, causing it to lock up. The security flaw was first discovered in 1997 by someone using the alias and has resurfaced many years later in operating systems such as Windows Server 2003 and Windows XP SP2.
