This is a networking security lab that helps you to check whether a router has been hijacked by cybercriminals. It can be found at https://www.f-secure.com/en/web/home_global/router-checker. A common threat today is DNS hijacking; one of the ways in which it is carried out is through unauthorized modifications of a router's configurations so that a third party can monitor, control, or redirect the traffic that is passing through the router. This security lab teaches you how to easily check whether a router has fallen victim to DNS hijacking. This knowledge can help victims stop attacks early enough before any significant damage is done. For example, in a situation where a router's DNS has been hijacked, a quick test using this tool will detect the attack and recommend an appropriate cause of action. This will prevent a user from being redirected to fake versions of genuine sites, such as in online banking, where their records or login credentials can be stolen and used to access their bank accounts. The tool is also important because it detects vulnerabilities or misconfigured settings in routers that can be exploited by criminals to harm users.
F-Secure Router Checker provides the interface shown in the following screenshot to allow users to analyze the settings of their routers for vulnerabilities. A user, therefore, needs to access the F-Secure website, and then select Online Tools and they will be directed to the router checker tool. Provided that they are connected to the internet, they just need to click on the Check your router button to start the analysis. After a few minutes, a report with the relevant information regarding the health of the router will be displayed with appropriate suggestions on how the issues can be rectified. The tool offers more tests for other devices, but these are offered at a subscription fee and so they might not be ideal for learning purposes:
