Common cybersecurity threats

1. Phishing


Phishing is a common type of cheating and counterfeiting activity in which fake websites, fake emails, and text messages are sent by intimidating a legal source such as a bank.

Ransomware is a form of malware that, after restricting access to files and computers, forces users to make payments to remove the restrictions. Phishing emails and website emails are frequent types of injections.

Ransomware is basically of two types, namely encrypted ransomware and lock screen ransomware. Encryption ransomware prevents the user from accessing a file on a computer’s hard drive by encrypting them, while locked-screen ransomware prevents access to the computer by imaging methods.

To gain access to the computer, the ransomware will display a notice or warning on the computer that it has been locked and request payment to unlock it.

3. Cryptojacking
