Malware, also known as malicious software, is a software that is designed to attack, harm or gain system access. Examples include:
- Viruses
- Worms
- Trojans
- Spyware
B. Phishing
Phishing is a method of fooling users into divulging sensitive information such as financial or passwords usually through fake email or messages. It can also be done through websites. Phishing attacks are among the most popular and efficient cyber-attacks.
C. Ransomware
Ransomware blocks a system or secures data until a payment is made. It could target business, individuals as well as government systems that cause financial and operational harm.
D. Social Engineering
This type of attack alters the human mind to gain access to sensitive data. For instance, a person could appear to be IT support to get your credentials.
E. Denial-of-Service (DoS) Attacks
DoS attacks cause chaos to websites, systems or networks with high traffic, making them inaccessible to users. This could disrupt companies and services in significant ways.
F. Advanced Persistent Threats (APTs)
APTs are targeted, long-term attacks that are designed to steal information or track systems for a period of time. They are typically sponsored by organized groups, or even nation-states.
