The Dark Web is a network of systems connected to the Internet designed to share information securely and anonymously. These capabilities are abused by cyber criminals to enable their activities, for example selling hacking tools or purchasing stolen information such as credit card data. Be aware that your information could be floating around the Dark Web, making it easier for cyber criminals to create custom attacks targeting you..
A common method cyber criminals use to hack into people's computers is to send them emails with infected attachments. Cyber attrackers will try to trick you into opening these attachments by making the email appear to come from someone or something your know or trust. Only open email attachments that you were expecting.
More and more scams and attacks are happening over the phone. Whenever you get an urgent phone call pressuring you to do something (such as a caller pretending to be the tax department or Microsoft Tech Support), be very suspicious. It's most likely a scammer trying to trick you out of money or pressure you into making a mistake. Protect yourself, simply hang up the phone or tell the person you can't help them. You are not being rude, the person on the other line is trying to take advantage of you.
Never send an email when you are angry or emotional; you will most likely regret it later. Instead, open up an email and write everything you feel, but do not send the email. (Be sure there is no name in the TO field so that you do not accidently send it.) After you have vented, go have a coffee or tea and come back an hour later and re-write your email then. Only reply to any type of emotional situation after you have had time to cool down.
Ransomware is a special type of malware. Once it infected your computer, it encrypts all of your files and demands you pay a ransom if you want your files back. Be suspicious of any emails trying to trick you into opening infected attachments or click on malicious links, common sense is your best defense. In addition. backups are often the only way you can recover from ransomware.
