The sooner the DNS hijacking problem is discovered, the better, so how can it be discovered in the first place?

IIS7 website monitoring

Check whether the website is hijacked, whether the domain name is walled, DNS pollution and other information.

Coping methods

1. Modify DNS manually

(1) fill in the username and password of your router and click "OK"

(2) in the "DHCP Server-DHCP" service, enter a more reliable address of 114.114.114.114 for the primary DNS server and 8.8.8.8 for the standby DNS server, and click Save.

2. Modify the router password

(1) enter the user name and password of your router. The initial user name of the router is admin, and the password is also admin. If you have modified it, fill in the modified user name and password, and click "OK".

(2) after filling in correctly, you will go to the router password modification page, which can be completed in the system tools-modify login password page (the original user name and password are the same as those entered in 2)

3. Prevent DNS hijacking

(1) Internet companies prepare more than two domain names. In the event of DNS hijacking, users can access another domain name.

(2) the Internet should further amend the emergency plan and strengthen the coordination process for domain name service providers.

(3) Domain name registrars and agents may become centralized targets in a specific period of time, which need to be prevented.

(4) the coordination and communication between the relevant domestic institutions and the relevant overseas institutions should be established quickly to assist domestic enterprises to deal with this incident in a rapid and timely manner.
