The attack affected 240,000 owners of the 9 year-old Dasan routers. Keep reading to find out how to beef up your router’s security.

The flaws were an authentication bypass (CVE-2018-10561) and a remote code execution vulnerability (CVE-2018-10562), which combined open the door for hackers to take control of a router to execute code on a device. Compromised routers have thus far largely been used to mine cryptocurrencies.

  • Configure the settings of your router to change the administrator username and password– this is typically done through a website portal of the router’s brand
  • Enable MAC address filtering so you have control over which devices are connected to your local WiFi network
  • Inquire if your router can undergo firmware updates
  • Ensure your devices are protected in real-time with an anti-virus, this solution will alert you if you’re surfing a network that might be compromised.
