In this case, most ordinary people are panicked and don't know what to do.

First of all, the crime of extortion needs to meet a specific behavior structure, that is, threatening others, and then causing the other party to have a fear. The other party disposes of the property based on this fear, so that the perpetrator or the third party can obtain the property, and finally the victim suffers property losses.

Although he was threatened by mail and was afraid, he didn't get rid of his property in the end. The anonymous sender didn't get the property for reasons other than his own, so his behavior constituted attempted extortion. In view of this situation, we should report the case to the public security organ in time.

Once this happens, don't panic, communicate with people around you and call the police in time.

Suggestions on user email security protection:

1, improve personal safety awareness, confirm whether the sending and receiving source is reliable when sending and receiving emails, don't click or copy the URL in the email at will, don't download attachments with unknown sources easily, and it is recommended not to open the emails of strangers.

2. Try not to log in to the mailbox under uncontrollable circumstances, such as computers in Internet cafes and other people's computers.

3. Ensure the environmental safety of the mail receiving and login terminal systems (PC, mobile phone, PAD, etc.). ), upgrade and update in time, fix vulnerability patches, install terminal security protection software and upgrade open monitoring in time to ensure the safety of email receiving and login environment.

4. The email password must be a strong password (if the password is longer than 12 characters, it must be a combination of numbers, English uppercase and lowercase letters and special characters), and the password should be changed regularly; Passwords should not be mixed with other services.

5. If a mail client is used, ensure the security of the client installation program, and configure mail sending and receiving according to the encrypted link mode supported by the mail server (such as SSL), instead of using plain text protocol to send and receive mail; It is recommended to use volume encryption (such as Bitlocker) for the volume where the mail client data files are located.

6. If you use a browser to send and receive e-mail, you need to use the HTTPS protocol to log in to the mailbox instead of using HTTP. 7. Standardize the mail signature according to the organization regulations.

8. Don't spread email addresses at will to reduce the possibility of attackers finding attack portals; If the email address must be made public, you can replace the @ symbol with other symbols to avoid being recognized by reptiles and becoming the target of spam and attack emails.
