1. The sender's address is wrong or suspicious.
Check if the sender's address is correct. Cybercriminals deceive you through the little things, the details. Sometimes it is just one letter that makes the difference and what should be email@example.com becomes firstname.lastname@example.org.
2. Links and call-to-action buttons can be dangerous.
Never click on a link or call-to-action button immediately. When you hover over them (without clicking), take a look and examine the address that appears at the bottom of your browser. Make sure this address looks real and authentic. If they are different or if you do not recognize the address, do not click.
3. Attachments can be even more dangerous.
It is strictly forbidden (yes, forbidden) to open immediately an attachment that you were not expecting. If it is from someone unknown to you, delete the email. Do not think twice. If it is from someone you know or an organization that you do business with, you need to check the email before opening the file. If necessary, contact the sender to confirm that the email is legitimate.
4. Spelling and grammar errors indicate frauds.
This is a quick tip. Be wary of emails that are full of misspellings or grammar errors. Probably, someone from a country other than yours is trying to lure and then take advantage of you and your organization in a negative way.
5. Miraculous and super lucrative offerings do not exist.
If you receive an email with promises of big profits and little investment, sorry to say that, but it is probably not true. The web is full of scams about inheritances, lottery prizes and great investments. Beware!
