What is Router Checker?

Router Checker is a free, web-based tool that checks your router’s connection settings. If your router isn’t configured to use an authorized DNS server, it might mean someone has modified it in order to hijack your Internet connection. Like any device on your home or office network, your router is vulnerable to attacks. And these attacks have the potential to put all of your connected devices at risk.

A DNS hijack means that someone has intentionally modified the settings on your router without your consent. This type of attack allows an attacker to monitor, control, or redirect your Internet traffic. For example, if your router’s DNS has been hijacked, any time you visit an online banking site on any device connected to that router, you may end up being redirected to a fake version of the site. From there, the attacker can gain access to your banking session and use it to transfer money without your knowledge. Home routers can be hacked if they contain vulnerabilities, or if they are misconfigured.

  • DNS hijacking can alter the advertisements you see while browsing. If you start seeing inappropriate ads, such as porn ads, on normal pages that you visit, it might be a sign that you’re in trouble.
  • Furthermore, advertisements can be modified to trick you. If you start to see warnings or notifications indicating there’s something wrong with your computer, you may be the target of DNS hijacking.
  • DNS hijacks redirect your browser from popular web pages (such as social media and online banking sites) to fake versions of those sites. These fake sites collect your login credentials, personal information, and sometimes even credit card information and banking credentials.

Safeguarding your Privacy

As a privacy protection measure, all IP addresses tested are anonymized by dropping the last octet, so that the information cannot be linked to an individual user. Aggregated, anonymized data is used only to make improvements to the service, for the benefit of all users.
