DDoS Attack
DDoS (Distributed Denial Of Service) attack involves a malicious user using several zombie computers to sabotage/ destroy a website or server.
This is easily done when a malicious user sends traffics to a computer /server over and over again, this increases traffic and thereby causing the website to slow, thereafter, crashing the server or website.
It is also possible for your computer to be used to perform these attacks. These can be done when a malicious user takes advantage of your computer vulnerabilities to 'distribute' these attacks or spam emails since this is a 'distribution' process, your computer can also be used to perform DDoS attacks.

A user might not be aware of these links and might think it’s a genuine link that directs them to the real website or sometimes a file they needed to check on, these links are made to steal data from you.
Phishing Attack: Computer threat
A phishing attack is a common computer threat that can allow a malicious user to perform the following.
- Stealing sensitive content from a computer.
- Having access to a private document stored in a computer.
- Stealing/ changing a user password.
- Engage in data espionage.
- Subduing of data.
