Remediation
- Remember that most of these hackers use phishing/fake emails to fool people.
- If you receive an email that you know you’re not supposed to get, immediately delete the email and don’t click on anything in it.
- Keeping security software and hardware updated is also an excellent way of preventing hackers from barging in.
