Secure Computing researchers have discovered a new variant of the DNSChanger Trojan in the wild that attacks routers, meaning any Web surfing computer on that network could be at risk of being redirected to a malicious Web site.
The DNSChanger Trojan changes the DNS settings to point to a host Web site address supplied by the attackers, Sven Krasser, director of data mining research at Secure Computing, said in an interview with CNET News.com on Tuesday. “Your network is essentially reconfigured to do all the (domain) name resolutions over this malicious name server,” he said.
The DNSChanger Trojan is able to access all the settings and functions on the router. It only knows about a few popular router Web interface URLs that it can use to change DNS settings at this time, but that is expected to change and more routers will be affected, according to a Secure Computing blog entry.
