New Malware Can Alter Your Wireless (Wi-Fi) Router and Steal Your Info

Zlob, one of the most common pieces of malicious software (according to Microsoft), has undergone a frightening transformation. After infecting a victim's PC, Zlob checks to see if the computer is connected to a wireless router (the device that helps create the Wi-Fi hotspot in your house). If connected, then Zlob attempts to gain access by using a list of common and default username and password combinations.Assuming Zlob gains access to the router, the software then changes the DNS settings on the router to send all traffic through a hackers' servers first. DNS servers act like a phone book for the Internet, connecting the user readable addresses like Switched.com to the IP addresses that are understood by computers.
Unfortunately, most people don't bother changing the default password on their routers, thus making it easier for Zlob to infiltrate computer networks and potentially steal personal data and information.
Avoiding being beaten by this attack is relatively easy. First, set up proper security software on your PC (anti-virus and a firewall) and keep it up to date. Second, always change the default administrator passwords on your equipment, especially your router. If an attacker is able to gain access to your router, it can access your entire computer network.
