There are many different types of cyber threats, but some of the most common are malware, ransomware, cryptoviruses, spear phishing, DDoS attacks, and insider threats.
Malware is a type of software designed to harm or disable computers. It can include worms, viruses, Trojans, and spyware.
Ransomware is malware that locks files on a computer and asks the user to pay to unlock them.
Cryptoviruses are a social engineering attack in which encrypted files are locked, and users must pay to unlock them.
Spear phishing is a type of phishing attack with the goal of getting an intended target user, organization, or business to hand over information. Insider threats are caused by humans, employees, contractors, or customers.
Insider threats are caused by humans, for example, employees, contractors, or customers.
DDoS attacks shut down targeted systems by disrupting traffic from multiple systems (for example, servers and websites). Advanced persistent threats (APTs) are prolonged targeted attacks.
Flooding the target with packets or connection requests can slow down a system or crash it, preventing legitimate traffic from using it.
Botnets, drive-by-download attacks, exploit kits, malvertising, vishing, credential stuffing attacks, cross-site scripting ( XSS ) attacks, and SQL injection attacks are common cyber threats. Malware variants vary from ransomware to worm to virus.
