Cybersecurity firm F-Secure today released a free tool to help protect Internet users from having their web traffic misdirected to websites that can spread malware or steal their personal information. Called Router Checker, the tool makes it easy to identify altered Internet settings that can let attackers manipulate what people see and do online.
Attacks that change router or Internet settings are popular amongst hackers because it allows them to reach large numbers of people without being noticed. According to F-Secure’s Labs, over 300,000 home or office routers were discovered to have altered settings in 2014, with each router potentially serving multiple computers, mobile phones and other devices. Attacks like these are difficult to notice because they can manipulate people in very subtle ways.
“Attacks that target Internet settings often go unnoticed because they don’t really have obvious symptoms for people to pick up on. People will suddenly see more ads, or they’ll be misdirected to a dangerous website that looks and feels safe”, says F-Secure Security Advisor Sean Sullivan. “This makes diagnosing these problems important, and Router Checker is all about making the diagnosis accessible and easy so that people don’t have to worry”.
Attackers try to manipulate people’s online behavior by changing their Internet settings to direct their traffic through “rogue DNS servers”. DNS Servers help computers and other devices find each other on the Internet. Attackers make money by setting up rogue servers to misdirect Internet users and connect them with websites that can contain fraudulent advertising, spread malware, or even trick them into revealing personal information. The new Router Checker makes sure the settings on people’s computers, phones, and even their routers connects them to safe DNS servers chosen by users or their Internet service providers.
