According to the researchers, between September 21 and 27,
the GhostDNS campaign compromised more than 100,000 routers,
of which 87.8 percent of devices (which equals to 87,800) are located in Brazil only,
which means Brazil is the primary target for GhostDNS attackers.

How to Protect Your Home Router from Hackers

In order to avoid yourself from being a victim to such attacks, you are recommended to ensure that your router is running the latest version of the firmware and set a strong password for the router web portal.

You can also consider disabling remote administration, changing its default local IP address, and hardcoding a trusted DNS server into your router or the operating system.

NetLab researchers also recommended the router vendors to increase the complexity of router default password and enhance the system security update mechanism for their products.
