Many home and small business users have a wired or wireless router that allows them to share their high-speed internet connection and that helps to protect their network.

According to a report from security vendor Symantec, failing to secure your router with a custom password can, with some help from badware delivered to your PC, lead to a pretty big security threat. This has already been demonstrated “in the wild” by an attack targeting Mexican internet users.

The solution, according to the Symantec report, is fairly simple: change your router’s password from the default to something you’ll remember. (Most major router vendors provide an instruction manual explaining how to log into the router and change the password.)
