This is a new method that any hacker and web criminal use to sneak into your system and steal your personal data, as well as the info about your internet history and, so on. They leverage some of the vulnerabilities of the interface about the management of the router and modify the DNS server (without us being aware of it).

How to Solve this Problem?

First, the next troubleshooting is generic. Hence, the proper solution varies as per the router brands.

It is advisable to have with you the router user manual.

  1. Verify that the firmware of the router is updated. Else, you would need to find all the information about how to update the firmware on the support area of the manufacturer’s website. For instance, D Link, TP Link, Asus, Netgear, or others.
  2. Access the router interface, find the address in the router manual or on the label under the device. It is usually: 192.168.1.1 or 192.168.0.1.
  3. Log in, and then enter the access credentials which you can also find in the manual or the label. If you are not able to log in or open the interface, then seemingly it has been modified. At this point, you must reset your router through the correct button which is half-hidden and placed on the backside of the device. Keep it pushed for around 10 seconds until all the router LED lights are off and then on again.
  4. After the router reset, you will go back to the manufacturing setting and you must set it up with the parameters of the Internet providers.
  5. Once you are inside the internet router setting interface, you must verify the DNS server, search for the DNS setup or the network setting. The advice is to set up the ones of Google which are 8.8.8.8 and 8.8.4.4 or, the ones of Open DNS: 208.67.222.222 and 208.67.220.220.
  6. If it is possible, since not all the routers allow it, you enter the Access Management section or Remote Management as per the router and click on “Enable”.
  7. For the D Link router. The router parameters must be:
  • Check on Enable remote management.
  • Remote Admin Port: 80.
  • Remote Admin Inbound Filter: Deny All.
  • Details: No one is allowed.

On the Remote Access Control, you should check the following:

  • FTP. Enabled for LAN and WAN.
  • HTTP. Enabled for LAN.
  • ICMP (Ping). Enabled for WAN.
  • TELNET. Enabled for LAN and WAN.
  • TFTP. Enabled for LAN and WAN.

Then apply the settings. Please take note that to access it, which is hidden, you just need to copy the link: http//192.168.1.1/scsrvcntr.html on the browser address bar. Then, remember to save the modifications.

As per for the TP Link router, it must be:

  • ACL. Activated.
  • ACL Rule Index: 1
  • Active: Yes.
  • Secure IP Address: 0.0.0.0 – 0.0.0.0
  • Application: ALL.
  • Interface: LAN.

Do not forget to check out the access control list for the modifications made.

  1. Change the password of the interface access and, for your online security, also the wifi password.
  2. Restart all the devices connected to the network, such as notebook, smartphone, tablet, and so on. This step is so important, else the DNS on these devices will remain the same and won’t change.
  3. To verify that the DNS service is secure, you can perform a DNS test on some website that makes it possible. If the response is “Address is probably not vulnerable”, then the DNS is safe.
