They ask you to click the link provided.” They claimed that “we are computer security expert from Microsoft. We have been alerted that your PC has been infected with malware and are contacting you to assist so that your network is not compromised.” Next day, when you tried to boot your computer, you realized that you cannot access into your files because they are all encrypted, and you have a message in the screen asking for money if you want to access your files again. What types of threats are in this scenario and how can you mitigate them?
