motive behind these scams is to extort money from the victim.

Cybercriminals can also install malware such as keylogging software

or backdoor Trojans in order to gain access to personal information.

How to stay safe: Don't fall for phone calls that tell you your software

or computer isn't working. Never give your personal information like

social security or credit card numbers to someone that you don't know

Botnets

A botnet is a string of infected, connected computers coordinated

together to perform a task. Botnets gain access to your machine

through some piece of malicious coding. Once the software is

downloaded, the botnet will now contact its master computer and let it

know that everything is ready to go. Now your computer, phone,
